-## A Beginner's Installation Guide to Taverna Server
+ * [Introduction](introduction.md)
+ * [Installing](install.md)
+ * [Using](usage.md)
-When installing Taverna Server, you *need* to decide whether to
-install in secure or insecure mode. In secure mode, the server
-enforces logins, ensures that they are done over HTTPS, and applies
-strong restrictions to what users can see of other users'
-workflows. In insecure mode, no restrictions are enforced which
-simplifies configuration but greatly reduces the overall system
-security. *Do not mix up installations between the two types.*
-You will need:
+# Export restrictions
-* **Unix** (e.g., Linux, OSX). Running Linux inside a virtual machine
- or in Docker works. Running directly on Windows is not supported.
+This distribution includes cryptographic software.
+The country in which you currently reside may have restrictions
+on the import, possession, use, and/or re-export to another country,
+of encryption software. BEFORE using any encryption software,
+please check your country's laws, regulations and policies
+concerning the import, possession, or use, and re-export of
+encryption software, to see if this is permitted.
+See <http://www.wassenaar.org/> for more information.
-* **Java 8** (or later).
+The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS),
+has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1,
+which includes information security software using or performing
+cryptographic functions with asymmetric algorithms.
+The form and manner of this Apache Software Foundation distribution makes
+it eligible for export under the License Exception
+ENC Technology Software Unrestricted (TSU) exception
+(see the BIS Export Administration Regulations, Section 740.13)
+for both object code and source code.
-* **Apache Tomcat** (use most recent version).
+The following provides more details on the included cryptographic software:
-If you are installing in secured mode (default) you will also need:
-
-* **SSL** (i.e., HTTPS) **host certificate**. This should not be
- self-signed and should have the hostname in the Common Name (CN)
- field. (Self-signed certificates or ones without the hostname in are
- exceptionally awkward for clients to work with, and proper
- single-host certificates are in reality very cheap. Save yourself a
- lot of work here!)
-
-* For the simplest operation, you should create a user `taverna` that is
- a member of the group called `taverna`. This user will be used for
- executing workflows, and does not need to allow anyone to log in as
- it.
-
-Stick to the Factory Defaults
------------------------------
-
-Taverna Server has a long list of things that may be configured,
-but it comes with “factory” settings that are correct in the majority
-of cases. Leave them alone for your first installation.
-
-Setting up Apache Tomcat
-------------------------
-
-Note that the instructions below do not describe setting up Tomcat
-users. These are not necessary for Taverna Server, as that needs
-finer-grained permission control than is normal for a webapp.
-
-
-### Installing on Debian Linux, Ubuntu
-
-On Debian Linux (and derivatives), you install Tomcat with:
-
- sudo apt-get install tomcat8 tomcat8-admin tomcat8-common tomcat8-user
-
-You then start Tomcat with:
-
- sudo /etc/init.d/tomcat8 start
-
-And stop it with:
-
- sudo /etc/init.d/tomcat8 stop
-
-It's configuration file (called `conf/server.xml` in the instructions below) will be in:
-
- /etc/tomcat8/server.xml
-
-It's webapp directory (`webapps` below) will be in:
-
- /var/lib/tomcat8/webapps/
-
-### Installing on RedHat Linux, Fedora, CentOS, Scientific Linux
-
-On RedHat Linux (and derivatives), you install Tomcat with:
-
- yum install tomcat8-webapps
-
-You then start Tomcat with:
-
- sudo service tomcat8 start
-
-And stop it with:
-
- sudo service tomcat8 stop
-
-It's configuration file (called `conf/server.xml` in the instructions below) will be in:
-
- /etc/tomcat8/server.xml
-
-It's webapp directory (`webapps` below) will be in:
-
- /var/lib/tomcat8
-
-### Installing on MacOS X, and using a baseline Apache distribution
-
-On OSX (or if otherwise installing from a standard Apache
-distribution), you install Tomcat by downloading from the distribution
-page at:
-
-* http://tomcat.apache.org/
-
-Both ZIP and `.tar.gz` download versions include a file `RUNNING.txt`
-that describes how to perform the installation, start the server, and
-stop it again.
-
-The normal location of the configuration file (`conf/server.xml` in
-the instructions below) is, for Tomcat 6.0.35:
-
- /usr/local/tomcat6.0/apache-tomcat-6.0.35/conf/server.xml
-
-And its `webapps` directory is at:
-
- /usr/local/tomcat6.0/apache-tomcat-6.0.35/webapps
-
-Installing an Unsecured Taverna Server
---------------------------------------
-
-This is not the default configuration of Taverna Server because it is
-_insecure_; there is no attempt to verify the identity of users or to
-keep them from interfering with each other's workflows. _We recommend
-that you use the secured version if possible._
-
-The insecure version is installed by:
-
-### First, place the WAR into Tomcat's webapps directory
-
-You may use a filename that relates to what URL you want Taverna Server to
-appear at within Tomcat (e.g., if you want it to be at `/taverna`, use the
-filename `webapps/taverna.war`).
-
-### Next, start Tomcat (if stopped), and shut it down again once it has unpacked the WAR.
-
-At this point, Taverna Server is installed but not usable.
-
-### Then configure for unsecure operation.
-
-Go to the unpacked WAR, find its `WEB-INF/web.xml` (with the above
-installation path, it would be
-`webapps/tavernaserver/WEB-INF/web.xml`), and change the lines:
-
- <param-value>WEB-INF/secure.xml</param-value>
- <!-- <param-value>WEB-INF/insecure.xml</param-value> -->
-
-to read:
-
- <!-- <param-value>WEB-INF/secure.xml</param-value> -->
- <param-value>WEB-INF/insecure.xml</param-value>
-
-This changes which part of the rest of the server configuration is
-used. It does so by altering what part of that XML file are commented
-out. One of those two `<param-value>` lines **must** be
-uncommented. The overall XML file **must** be valid.
-
-### Finally, start Tomcat.
-
-> **NB:** When accessing an unsecured Taverna Server, for most
- operations (such as submitting a run) you will need to pass the
- credentials for the default user. The default user has username
- `taverna` and password `taverna`.
-
-Installing a Secured Taverna Server
------------------------------------
-Taverna Server 2.5 is installed in secure mode by doing this:
-
-### First you need to enable SSL on Tomcat.
-
-With Tomcat not running, make sure that its `conf/server.xml` file
-contains a `<Connector>` definition for SSL HTTP/1.1. The file should
-contain comments on how to do this. Here's an example:
-
- <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
- maxThreads="150" scheme="https" secure="true"
- clientAuth="false" sslProtocol="TLS" keystorePass="tomcat"
- keystoreFile="conf/tavserv.p12" keystoreType="PKCS12" />
-
-This configuration enables secure access on port 8443 (HTTPS-alt;
-strongly recommended) with the server using the key-pair that has been
-placed in a standard PKCS #12 format file in the file `tavserv.p12` in
-the same directory as the configuration file; the key-pair file will
-be unlocked with the (rather obvious) password “`tomcat`”.
-
-Note that if the configuration file is located below `/etc`, it is
-recommended that you specify the full path to the PKCS #12 file. You
-should also ensure that the file can only be read by the Unix user
-that will be running Tomcat.
-
-### Next, you need to grant permission to the Tomcat server to run code as other users.
-
-In particular, it needs to be able to run the Java executable it is
-using as other people via `sudo`. You _should_ take care to lock this
-down heavily. You do this by using the program visudo to add these
-parts to the sudo configuration. Note that each goes in a separate
-part of the overall file, and that we assume below that Tomcat is
-running as the user `tavserv`; you will probably need to change (e.g.,
-to `tomcat` or `nobody`) as appropriate.
-
-This defines some flags for the main server user:
-
- Defaults:tavserv !lecture, timestamp_timeout=0, passwd_tries=1
-
-This defines a rule for who the server can switch to. Let's say that
-they have to be a member of the Unix user group `taverna`; if a user
-isn't in that group, they cannot use Taverna Server. (Note that `root`
-should not be part of the group!)
-
- Runas_Alias TAV = %taverna
-
-This creates the actual permission, saying that the `tavserv` user may
-run anything as any user in the alias above (i.e., in the `taverna`
-group). The `NOPASSWD` is important because it allows Taverna Server
-to do the delegation even when running as a user that can't log in.
-
- tavserv ALL=(TAV) NOPASSWD: ALL
-
-### Now, place the WAR into Tomcat's `webapps` directory.
-
-You may use a filename that relates to what URL you want Taverna Server to
-appear at within Tomcat (e.g., if you want it to be deployed at
-`/taverna`, rename the WAR to a filename like `webapps/taverna.war`).
-
-### Finally, start Tomcat.
-
-Taverna Server should then become available at
-the equivalent of http://localhost:8080/taverna-server/
+* Taverna Server's `CertificateChainFetcher` uses
+ [Java Secure Socket Extension](https://docs.oracle.com/javase/8/docs/technotes/guides/security/jsse/JSSERefGuide.html)
+ (JSS) to pre-fetch certificates of SSL-secured web services accessed by Taverna workflows.
+* Taverna Server's support for propagating username/password credentials in
+ `SecurityContextFactory` relies on
+ [BouncyCastle](https://www.bouncycastle.org/) bcprov encryption library and
+ [Java Cryptography Extension](http://docs.oracle.com/javase/8/docs/technotes/guides/security/crypto/CryptoSpec.html)
+ (JCE) to generate a keystore for Taverna Command-line tool.
+ The [JCE Unlimited Strength Jurisdiction Policy](http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html)
+ may need to be installed separately.
+* Taverna Server may interact with the credential manager support in
+ [Apache Taverna Command-line Tool](https://taverna.incubator.apache.org/download/commandline/)
+ to provide a keystore of client credentials and trusted certificates for SSL-secured web services.
+* After building, the
+ `taverna-server-webapp/target/taverna-server.war` will include
+ dependencies that are covered
+ by export restrictions, including:
+ [BouncyCastle](https://www.bouncycastle.org/) bcprov encryption library,
+ [Apache HttpComponents](https://hc.apache.org/) Core and Client,
+ [Apache Derby](http://db.apache.org/derby/),
+ [Jetty](http://www.eclipse.org/jetty/),

+workflows.
+
+In-depth documentation is available for:
+
+* [Installation guide](install)
+* [API User guide](usage)
+
+
+# Prerequisites
+
+* Java 1.8
+* [Apache Maven](https://maven.apache.org/download.html) 3.3.9 or newer
+* a Java Servlet container, e.g. [Apache Tomcat](https://tomcat.apache.org/)
+
+
+# Building
+
+After [downloading Taverna Server](/download/server/) and unpacking,
+then to build, use:
+
+ mvn clean install
+
+This will build each module and run their tests.
+
+You should then find `taverna-server.war` in the folder
+`taverna-server-webapp/target/`
+
+Below we'll show how to install and configure this _WAR file_
+with Apache Tomcat.
+
+
+## A Beginner's Installation Guide to Taverna Server
+
+When installing Taverna Server, you *need* to decide whether to
+install in secure or insecure mode. In secure mode, the server
+enforces logins, ensures that they are done over HTTPS, and applies
+strong restrictions to what users can see of other users'
+workflows. In insecure mode, no restrictions are enforced which
+simplifies configuration but greatly reduces the overall system
+security. *Do not mix up installations between the two types.*
+
+You will need:
+
+* **Unix** (e.g., Linux, OSX). Running Linux inside a virtual machine
+ or in Docker works. Running directly on Windows is not supported.
+
+* **Java 8** (or later).
+
+* **Apache Tomcat** (use most recent version).
+
+If you are installing in secured mode (default) you will also need:
+
+* **SSL** (i.e., HTTPS) **host certificate**. This should not be
+ self-signed and should have the hostname in the Common Name (CN)
+ field. (Self-signed certificates or ones without the hostname in are
+ exceptionally awkward for clients to work with, and proper
+ single-host certificates are in reality very cheap. Save yourself a
+ lot of work here!)
+
+* For the simplest operation, you should create a user `taverna` that is
+ a member of the group called `taverna`. This user will be used for
+ executing workflows, and does not need to allow anyone to log in as
+ it.
+
+Stick to the Factory Defaults

+
+Taverna Server has a long list of things that may be configured,
+but it comes with “factory” settings that are correct in the majority
+of cases. Leave them alone for your first installation.
+
+Setting up Apache Tomcat
+------------------------

+Note that the instructions below do not describe setting up Tomcat
+users. These are not necessary for Taverna Server, as that needs
+finer-grained permission control than is normal for a webapp.

+
+On OSX (or if otherwise installing from a standard Apache

+page at:
+
+* http://tomcat.apache.org/
+
+Both ZIP and `.tar.gz` download versions include a file `RUNNING.txt`
+that describes how to perform the installation, start the server, and
+stop it again.
+
+The normal location of the configuration file (`conf/server.xml` in
+the instructions below) is, for Tomcat 6.0.35:
+
+ /usr/local/tomcat6.0/apache-tomcat-6.0.35/conf/server.xml

+
+ /usr/local/tomcat6.0/apache-tomcat-6.0.35/webapps
+
+Installing an Unsecured Taverna Server
+--------------------------------------
+
+This is not the default configuration of Taverna Server because it is
+_insecure_; there is no attempt to verify the identity of users or to
+keep them from interfering with each other's workflows. _We recommend
+that you use the secured version if possible._
+
+The insecure version is installed by:
+
+### First, place the WAR into Tomcat's webapps directory
+
+You may use a filename that relates to what URL you want Taverna Server to
+appear at within Tomcat (e.g., if you want it to be at `/taverna`, use the
+filename `webapps/taverna.war`).
+
+### Next, start Tomcat (if stopped), and shut it down again once it has unpacked the WAR.
+
+At this point, Taverna Server is installed but not usable.
+
+### Then configure for unsecure operation.
+
+Go to the unpacked WAR, find its `WEB-INF/web.xml` (with the above
+installation path, it would be
+`webapps/tavernaserver/WEB-INF/web.xml`), and change the lines:
+
+ <param-value>WEB-INF/secure.xml</param-value>
+ <!-- <param-value>WEB-INF/insecure.xml</param-value> -->
+
+to read:
+
+ <!-- <param-value>WEB-INF/secure.xml</param-value> -->
+ <param-value>WEB-INF/insecure.xml</param-value>
+
+This changes which part of the rest of the server configuration is
+used. It does so by altering what part of that XML file are commented
+out. One of those two `<param-value>` lines **must** be
+uncommented. The overall XML file **must** be valid.
+
+### Finally, start Tomcat.
+
+> **NB:** When accessing an unsecured Taverna Server, for most
+ operations (such as submitting a run) you will need to pass the
+ credentials for the default user. The default user has username
+ `taverna` and password `taverna`.
+
+Installing a Secured Taverna Server
+-----------------------------------
+Taverna Server 2.5 is installed in secure mode by doing this:
+
+### First you need to enable SSL on Tomcat.
+
+With Tomcat not running, make sure that its `conf/server.xml` file
+contains a `<Connector>` definition for SSL HTTP/1.1. The file should
+contain comments on how to do this. Here's an example:
+
+ <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
+ maxThreads="150" scheme="https" secure="true"
+ clientAuth="false" sslProtocol="TLS" keystorePass="tomcat"
+ keystoreFile="conf/tavserv.p12" keystoreType="PKCS12" />
+
+This configuration enables secure access on port 8443 (HTTPS-alt;
+strongly recommended) with the server using the key-pair that has been
+placed in a standard PKCS #12 format file in the file `tavserv.p12` in
+the same directory as the configuration file; the key-pair file will
+be unlocked with the (rather obvious) password “`tomcat`”.
+
+Note that if the configuration file is located below `/etc`, it is
+recommended that you specify the full path to the PKCS #12 file. You
+should also ensure that the file can only be read by the Unix user
+that will be running Tomcat.
+
+### Next, you need to grant permission to the Tomcat server to run code as other users.
+
+In particular, it needs to be able to run the Java executable it is
+using as other people via `sudo`. You _should_ take care to lock this
+down heavily. You do this by using the program visudo to add these
+parts to the sudo configuration. Note that each goes in a separate
+part of the overall file, and that we assume below that Tomcat is
+running as the user `tavserv`; you will probably need to change (e.g.,
+to `tomcat` or `nobody`) as appropriate.
+
+This defines some flags for the main server user:
+
+ Defaults:tavserv !lecture, timestamp_timeout=0, passwd_tries=1
+
+This defines a rule for who the server can switch to. Let's say that
+they have to be a member of the Unix user group `taverna`; if a user
+isn't in that group, they cannot use Taverna Server. (Note that `root`
+should not be part of the group!)
+
+ Runas_Alias TAV = %taverna
+
+This creates the actual permission, saying that the `tavserv` user may
+run anything as any user in the alias above (i.e., in the `taverna`
+group). The `NOPASSWD` is important because it allows Taverna Server
+to do the delegation even when running as a user that can't log in.
+
+ tavserv ALL=(TAV) NOPASSWD: ALL
+
+### Now, place the WAR into Tomcat's `webapps` directory.
+
+You may use a filename that relates to what URL you want Taverna Server to
+appear at within Tomcat (e.g., if you want it to be deployed at
+`/taverna`, rename the WAR to a filename like `webapps/taverna.war`).
+
+### Finally, start Tomcat.
+
+Taverna Server should then become available at
+the equivalent of http://localhost:8080/taverna-server/

The blue states are the initial and final states, and all states in *italic* cannot be observed in practice. The black arrows represent automatic state changes, the blue arrows are for manually-triggered transition, and the red arrows are destructions, which can be done from any state (other than the initial unobservable one) and which may be either manually or automatically triggered; automatic destruction happens when the run reaches its expiry time (which you can set but cannot remove). Note that there are two transitions from *Operating* to *Finished*; they are not equivalent. The automatic transition represents the termination of the workflow execution with such outputs produced as are going to be generated, whereas the manual transition is where the execution is killed and outputs may be not generated even if they conceptually existed at that point. Also note that it is only the transition from *Initialized* to *Operating* that represents the start of the workflow execution engine.
