Hello,

My eclipse throws loads of this exception every time I try to do anything, e.g. If try to click on a project with the right button.

java.lang.ClassCastException: org.eclipse.jst.j2ee.application.internal.impl.ApplicationImpl cannot be cast to org.eclipse.jst.javaee.application.Application

Session Data:

eclipse.buildId=M20090917-0800
java.version=1.6.0_17
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_GB
Framework arguments:  -product org.eclipse.epp.package.jee.product
Command-line arguments:  -os win32 -ws win32 -arch x86 -product org.eclipse.epp.package.jee.product

It's been impossible to work lately. I downloads a new eclipse and "started over again" but I get the same exceptions. I guess it is something related with my projects.

I'm trying to attach the session's log but the upload feature is not working for me.

Any help is appreciated as I'm stuck and can't work at all.

Regards,
Luiz Abrahao

Open a bug report against WebTools. This is the best way to get this
investigated and fixed.

Thank you for your reply Oliver.

I opened the bug report. I'm afraid nobody will put much (or any) effort on it though.

It's difficult to replicate and as far as I know it's not a problem many people come across.

For me it's critical as I'm not able to work and I ran out of things to do that are not related with eclipse. Now I'm literally stuck watching my deadlines passing by. Sad

Thanks,
Luiz

Why don't you try to patch it yourself ? This is the magic of open source.

Hi Oliver,

I wish I had the knowledge to do so.

Carl Anderson found the root of the problem.

My EAR module had the EAR 1.3 facet installed when the application descriptor had the version attribute set to 5. So, as far as I understood, if you don't keep the facet and the descriptor in sync this problem happens.

Thanks,
Luiz

I guess you might have found a solution for this problem, I encountered a same problem and fixed it by changing couple of configuration on my eclipse project

<workspace-dir>/<project>/.settings/org.eclipse.wst.common.project.facet.core.xml

should change the following
<installed facet="jst.ear" version="1.4"/>
to
<installed facet="jst.ear" version="5.0"/>

and also in the same folder
there is a file called org.eclipse.wst.common.component
should change the following
<project-modules id="moduleCoreId" project-version="1.4.0">
to
<project-modules id="moduleCoreId" project-version="1.5.0">

Hope it would help.
Cheers
