# New Features

<a name="OpenEJB1.0-RemoteServersupportsEJBinvocationsoverHTTP"></a>
## Remote Server supports EJB invocations over HTTP

Having a hard time with those pesky firewalls?	Our Remote Server now has
it's own HTTP front end which supports a stripped-down version of HTTP
specifically for supporting our EJB protocol.  Remote invocations from EJB
Clients can now be layered over HTTP and serviced by our standalone EJB
Server.

<a name="OpenEJB1.0-TomcatIntegrationsupportsRemoteEJBClients"></a>
## Tomcat Integration supports Remote EJB Clients

No extra ports necesarry.  Simply point your EJB client to the URL of the
LoaderSerlvet and go!  All HTTP requests to the LoaderServlet will be sent
into the embedded OpenEJB container.  Combine this with the [Collapsed EAR](collapsed-ear.html)
 approach to embedding OpenEJB and you get a single webapp containing it's
own private EJBs and OpenEJB container which can now support it's own
remote java clients as well as web browsers.  Or combine this with
traditional style of embedding OpenEJB into the root of Tomcat at a global
level and turn your Tomcat server into a no holds-barred EJB server.  If
you want no remoting at all, simply remove the LoaderServet's
serlvet-mapping and the door is closed.

<a name="OpenEJB1.0-Bettercommandlinesupport"></a>
## Better command line support

OpenEJB and it's tools can now be executed via an executable jar.  Simply
'java -jar openejb-core-1.0.jar start' and the server will start.  Or 'java
-jar openejb-core-1.0.jar deploy' to deploy an EJB application.  This makes
it far easier to use OpenEJB in scripts and third party tools like IDEs. 
You can even add your own custom commands to the command line via any class
with a static main method and a properties file in the classpath at
META-INF/org.openejb.cli/mycommand.

<a name="OpenEJB1.0-Xinet.dstyleprotocolconfiguration"></a>
## Xinet.d style protocol configuration

Protocols in OpenEJB are a pluggable, snap-in, style concept.  Anything
that consumes data on a socket is wrapped with a standard set of xinet.d
like services for ip and port management, connection pooling, host-based
authorization and more.    Want to disable a protocol and prevent it from
starting?  Want to change it's port?  Want to limit the max number of
concurrent connections or restrict access to clients on specific IP
addresses?  Just crack open that protocol's properties files and edit away.

<a name="OpenEJB1.0-EJB2.0Localinterfacesupport"></a>
## EJB 2.0 Local interface support

  OpenEJB now has support for EJB 2.0 Local Interfaces.  This is very nice
for when OpenEJB is combined with Tomcat  or embedded in another
application where Remote interfaces  are not always needed.  See the
"Moviefun" example in the  source or binary distributions for how to use
them.  Note that no other EJB 2.0 features (such as CMP 2 or MDBs)
  are supported in the OpenEJB 1.x codebase.

<a name="OpenEJB1.0-CollapsedEARsupport"></a>
## Collapsed EAR support

 [Collapsed EAR](collapsed-ear.html)
s are an OpenEJB invention allowing you to  combine your ejbs and servlets
in the same archive and  classloader.  This is essentially a new way to
embed OpenEJB  into Tomcat so that OpenEJB and your EJBs are loaded only 
into your webapp.  Combine this with an embedded database  and you have a
complete mini-J2EE environment that can be  hosted in your Tomcat webapp
space.

  See the "Moviefun" example in the distribution which will  be online for
a short while here:

<a name="OpenEJB1.0-UnpackedEJBJarsupport"></a>
## Unpacked EJB Jar support

  It is now possible to deploy and run EJB apps that are not  in a *.jar
archive.  For example, for ejb app located at:

    /home/jsmith/myejbapp/META-INF/ejb-jar.xml

  Simply add a Deployments declaration to the openejb.conf  like the
following:

    <Deployment dir="/home/jsmith/myejbapp" />

<a name="OpenEJB1.0-AutoDeployforSimpleApps"></a>
## Auto Deploy for Simple Apps

  In OpenEJB 1.0 beta1, the use of openejb-jar.xml is not  required for
ejb-jar.xml files that do not contain CMP  EntityBeans or ejbs with
multiple datasource references.

<a name="OpenEJB1.0-MacOSXUsers"></a>
## Mac OSX Users

The speed of the Remote Server has been improved tremendously  to
compensate for differing default parameters for TCP Socket  creation and
closing in the Mac OSX Java VM.  This makes sequential	calls from a Remote
Client to the Server several times faster.


<a name="OpenEJB1.0-UpgradeNotes"></a>
# Upgrade Notes

<a name="OpenEJB1.0-CMPconfigchange"></a>
## CMP config change

In 0.9.2 and before, the JDO database was using the private JNDI namespace
of the very first CMP accessed to grab a datasource and hold onto it for
use on all requests into the CMP container.  This was configured with
something like this:

    <database name="Global_TX_Database" engine="instantdb">
       <jndi name="java:comp/env/jdbc/basic/entityDatabase" />
       <mapping href="conf/default.cmp_mapping.xml" />
    </database>


This was just wrong.  We've switched it so that the "jndi" tag of a Castor
database.xml file can be set directly to the global JNDI name of a
Connector element declared in an openejb.conf file.
    
     <database name="Global_TX_Database" engine="instantdb">
         <jndi name="java:openejb/connector/Default JDBC Database" />
         <mapping href="conf/default.cmp_mapping.xml" />
     </database>


This is still not so optimal as we do not want to people using OpenEJB's
internal jndi and encourage people to become dependent on it.  Newer
releases of Castor allow for a completely programmatic way to configure a
JDO database.  In future releases, these global and local database files
will go away all together!  You will only need to specify your mapping.xml
and will be able to pack it in your ejb jar.
