<p>
This module implements the configuration editors that support editing "Sun specific"
deployment descriptors. These editors are based on an extended version of the
API's defined in JSR-88, that is customizer based.
</p>
<p>
It was developed by refactoring the server integration module and jars that
supported SJSAS 8.1 PE in NetBeans 5.0. The goal of the refactoring is to allow
multiple integration modules (for various Sun projects) to re-use these editors.

<question id="compat-standards" when="init">
Does the module implement or define any standards? Is the
implementation exact or does it deviate somehow?
</question>

<answer id="compat-standards">
<p>
The module depends on the implementation of a few standards from the Application Server itself. The plugin dynamically loads JAR files from the app
server installation directory to get access to a J2EE 1.4 specification implementation : EJB, JWS, Web Services, JSR 88, JMX,...

<question id="compat-version" when="impl">
Can your module coexist with earlier and future
versions of itself? Can you correctly read all old settings? Will future
versions be able to read your current settings? Can you read
or politely ignore settings stored by a future version?
<hint>
Very helpful for reading settings is to store version number
there, so future versions can decide whether how to read/convert
the settings and older versions can ignore the new ones.
</hint>
</question>
-->
<answer id="compat-version">
<p>
There is an earlier version of the plugin that shipped with NetBeans 3.6 in auto update center. These settings are not compatible with the new plugin, but
the migration is as simple as specifying again the Application Server Installation Directory.
We expect future versions of the plugin to understand the current structure of the settings going forward.

<answer id="dep-non-nb">
<p>
The plugin depends a lot on the Application Server 8.1 product and needs an installation of it to be fully functional. We need for example the
JSR 88 implementation provided by the application server. We also need all the CLients APIS for Management of an app server.
We also depends on the directory structure of an application server installation area, to get access to a few command line tools like asadmin, verifier or the log files.

<answer id="deploy-jar">
<p>
The plugin is a more than a JAR file, in order to be able to dynamically load JAR files from the Application Server product itelf.
We have abstracted via interfaces the communication between the real netbeans module (loaded by a NetBeans Class loader) and the App Server jars.
So far, the structure is as follow:
moduleles/org-netbeans-modules-j2ee-sun-ide.jar
that depends on
modules/ext/appserv-jsr88.jar
modules/ext/validation.jar

<question id="deploy-packages" when="init">
Are packages of your module made inaccessible by not declaring them

NetBeans module system allows restriction of access rights to

<p>
Yes, the plugin has a specific class loader to load the necessary Spec implementations JARs from the application server area.
We could have copied the necessary jars under modules/ext, but 1/ this is not ARC compliant, and 2/ the size of the external jars is way too big to be bundled
within NetBeans. The NetBeans product is tracking the issue related to loading external jar files (i.e outside the netbeans installation directory with this bug:

<hint>
Often <code>JComponent.getClientProperty</code>, <code>Action.getValue</code>

a behavior of some code. This of course forms an interface that should
be documented. Also if one depends on some interface that an object

Check for cases when you have an object of type A and you also
expect it to (possibly) be of type B and do some special action. That
should be documented. The same applies on operations in meta-level
(Class.isInstance(...), Class.isAssignableFrom(...), etc.).

We do use introspection as of today to handle the dynamic aspect of the fact that the application server JARs location is unknown by the plugin code. A special

If your module defines any APIs, or has complex internal structures

data against concurrent access, race conditions, deadlocks, etc.,
and whether such rules are enforced by runtime warnings, errors, assertions, etc.
Examples: a class might be non-thread-safe (like Java Collections); might
be fully thread-safe (internal locking); might require access through a mutex
(and may or may not automatically acquire that mutex on behalf of a client method);
might be able to run only in the event queue; etc.

If you do a lot of tricks when adding actions to regular or context menus, you can significantly
slow down display of the menu, even when the user is not using your action. Pay attention to
actions you add to the main menu bar, and to context menus of foreign nodes or components. If
the action is conditionally enabled, or changes its display dynamically, you need to check the
impact on performance. In some cases it may be more appropriate to make a simple action that is
always enabled but does more detailed checks in a dialog if it is actually run.

We do implement a "wait-node" for all the management calls within the nodes int he runtime tab. For example, querying the application server for the list of deployed applications can take a few seconds.
This "wait-node" makes sure the UI is responsive for other parallel activities within the IDE.

Does your module execute any long-running tasks?
<hint>Long running tasks should never block
AWT thread as it badly hurts the UI
<a href="http://performance.netbeans.org/responsiveness/issues.html">
responsiveness</a>.
Tasks like connecting over
network, computing huge amount of data, compilation
be done asynchronously (for example
using <code>RequestProcessor</code>), definitively it should
not block AWT thread.

<p>
Starting and stopping the application server call take a long time. The UI is not blocked during this step, and the IDE, via J2EEServer module is showing a progess bar.
There is a time out of 2 minutes. Also, the plugin can detect is the target server is stopped in debug mode at a breakpoint. This way, the plugin stops doing administrative request
calls, because these calls would not return.

<question id="perf-scale" when="init">
Which external criteria influence the performance of your
program (size of file in editor, number of files in menu,
in source directory, etc.) and how well your code scales?
<hint>
Please include some estimates, there are other more detailed
questions to answer in later phases of implementation.
</hint>
</question>

<answer id="perf-scale">
<p>
The Deployment time of J2EE applications depends a lot on the state of the running server (how many applications have been deployed, how many users are using the server, etc).
Since this is a development environment, we expect that the server is per user, and this user can undeploy unecessary applications, in case of performance issues.

<question id="perf-spi" when="init">
How the performance of the plugged in code will be enforced?
<hint>
If you allow foreign code to be plugged into your own module, how
do you enforce that it will behave correctly and quickly and will not
negatively influence the performance of your own module?
</hint>
</question>

<answer id="perf-spi">
<p>
So far, no foreign code can be plugged to this module.

<question id="perf-startup" when="final">
Does your module run any code on startup?
</question>
-->
<answer id="perf-startup">
<p>
Yes, as a side effect of the fact that the servers have to be registered. Database registration is done in a lazy manneer.

<question id="perf-wakeup" when="final">
Does any piece of your code wake up periodically and do something
even when the system is otherwise idle (no user interaction)?
</question>
-->
<answer id="perf-wakeup">
<p>
The is one optional wakeup thread whenever the user has decided to view the local application server log file. As soon as the log viewer dialog is closed, the thread is stopped.

<question id="resources-file" when="final">
Does your module use <code>java.io.File</code> directly?
<hint>
NetBeans provide a logical wrapper over plain files called
<code>org.openide.filesystems.FileObject</code> that
provides uniform access to such resources and is the preferred
way that should be used. But of course there can be situations when
this is not suitable.
</hint>
</question>
-->
<answer id="resources-file">
<p>
java.io.File is used for accessing the application server log file, as well adn the default-web.xml file to configure the HTTP monitor tool.
All other resources are accessed via the NetBeans APIS.

<!--
<question id="resources-layer" when="final">
Does your module provide own layer? Does it create any files or
folders in it? What it is trying to communicate by that and with which
components?
<hint>
NetBeans allows automatic and declarative installation of resources
by module layers. Module register files into appropriate places
and other components use that information to perform their task
(build menu, toolbar, window layout, list of templates, set of
options, etc.).
</hint>
</question>

<answer id="resources-layer">
<p>
Yes the module has it's own layer file for declaring the resource templates, the online help system, and some J2EE Server specific configuration for a few factories.

<!--
<question id="resources-mask" when="final">
Does your module mask/hide/override any resources provided by other modules in
their layers?
<hint>
If you mask a file provided by another module, you probably depend
on that and do not want the other module to (for example) change
the file's name. That module shall thus make that file available as an API
of some stability category.

<question id="resources-read" when="final">
Does your module read any resources from layers? For what purpose?

<question id="security-grant" when="final">
Does your code grant additional rights to some other code?
<hint>Avoid using a class loader that adds extra
permissions to loaded code unless really necessary.
Also note that your API implementation
can also expose unneeded permissions to enemy code by
calling AccessController.doPrivileged().</hint>

<question id="exec-ant-tasks" when="impl">
Do you define or register any ant tasks that other can use?
<hint>
If you provide an ant task that users can use, you need to be very
careful about its syntax and behaviour, as it most likely forms an
API for end users and as there is a lot of end users, their reaction
when such API gets broken can be pretty strong.
</hint>
