Ok... so here's what I've discovered so far. Methodology is similar to yours.
Open an eclipse with wtp-2.0.1 workspace and create a seam project (seam 2),
make sure it deploys appropriately (it does), close down eclipse.
Open a new eclipse with wtp-2.0.2 but use the same workspace.
The very first thing I notice is a stacktrace in the output (starting from
command-line). Trace is as follows:
[EMAIL PROTECTED] eclipse]$ ./eclipse
Listening for transport dt_socket at address: 4000
*** ERROR ***: Wed Mar 12 19:27:50 EDT 2008
org.eclipse.jst.j2ee.commonarchivecore.internal.exception.OpenFailureException:

at org.eclipse.jst.jee.internal.deployables.JEEDeployableFactory.createB
inaryModules(JEEDeployableFactory.java:163)
Tracing through, this happens during startup for me because I made sure to have
the JBossServers view up which probably helped force the initialization of the
deployable factories. blah blah ;) Moving along.
I stopped the trace at createBinaryModules because this, I feel, is the
important part. This is where the model for this project is started. Looking
at the code for this method, we see the following. (context: It's parsing
through the list of objects in the application.xml's module tags). Here are
some snippets.
| if (moduleComponent.isBinary()) {
| // create an ear edit, app only if the module is binary
prevents exceptions when there
| // is no deployment descriptor in many cases see bug 174711
| if(earEdit == null){
| earEdit =
EARArtifactEdit.getEARArtifactEditForRead(component.getProject());
| app = earEdit.getApplication();
| }
| // if we are missing the application.xml, cannot check for
module URI so assume an archive
| if (app == null) {
| continue;
| }
|
So it's obvious they're trying to make sure if it's binary and has no
application.xml, to just give up on it and accept that it's a generic archive.
The problem is despite their best efforts, this is not working. It is returning
something. app is not null. The code fails at the following place.
| else if (j2eeModule.isJavaModule()) {
| moduleEdit =
ComponentUtilities.getArtifactEditForRead(moduleComponent,
| J2EEProjectUtilities.APPLICATION_CLIENT);
| ApplicationClient appClient = (ApplicationClient)
moduleEdit.getContentModelRoot();
| moduleType = J2EEProjectUtilities.APPLICATION_CLIENT;
| moduleVersion = appClient.getVersion();
| }
|
So basically, the top snippet tries to screen out generic java modules, but
somehow fails. When it gets to the second snippet, it's assuming it's an
application client jar, not a generic archive.
This is most definitely an upstream wtp bug and I will mark it as such and push
it to tim and the server team. I'll also continue looking into it and try to
provide a patch to eclipse.
