I have a project that I have just imported from CVS. It is working in several dozen other developers IDE, but in my case, it is reporting a problem:
CHKJ3000E: WAR Validation Failed: com.ibm.etools.j2ee.commonarchivecore.exception.DeploymentDescriptorLoadException: WEB-INF/web.xml
Googling for this suggests its an issue with the way Eclipse loads the context. For some users, cleaning the project works. It didn't for me.
Any ideas on what I could attempt next to resolve it?
This is a common problem and is because of cache maintained by eclipse.
Try clearing cache of plugins and doing a full clean ,you can also delete the existing server and create a new one.
Refer here for more details , see people gave faced similar issue and clean and removing cache and restarting stuff like this have solved it for them.
