Subject:	[wtp-dev] Exception when deploying project to Tomcat from Eclipse

---

Hi. I could use some assistance with the
following problem:
“Could not publish server configuration:
null. java.lang.NullPointerException” when deploying a project to Tomcat.
 
Steps:
1. Create new server based on Tomcat 5.5
runtime
2. Choose a single project to deploy on this
server
2. Rename server, check “Serve modules without
publishing” and “Publish module contexts to separate XML files”.
3. File + Save
4. Close file and click OK to rename configuration
files to match new server name.
5. Try to run the server – causes the error
when it attempts to publish
 
Environment:
- Tomcat 5.5
- Eclipse 3.3.1.1
 
Things that did not fix the problem:
1. unchecking “Publish module contexts to
separate XML files”
2. clean the server
3. clean the workspace
4. restart Eclipse
5. try Tomcat 6.x runtime
6. delete and recreate the servers
7. delete and recheckout the project, then
re-add to server
8. rebuild entire workspace
9. bang head against desk
 
Temporary workaround: 
- Uncheck the “Serve modules without publishing”
checkbox – don’t want to do this as it messes with a servlet filter we’ve
written (which may be an issue on our part).
 
Things that did fix the problem:
1. Rename the entire project and web application
– don’t want to do this, though, since it puts me out of sync with the
rest of the team. After a few weeks, the problem mysteriously reappeared.
It seems to be intermittent. If renaming the project and web app fixed
it, maybe it’s related to some kind of caching problem.
 
Is anyone else having this problem?
- Yes, one other person. The other team members
seem to be running ok.
 
A google search turned up this link (http://dev.eclipse.org/newslists/news.eclipse.webtools/msg15819.html),
but everything looks ok on our server.xml. I could provide this if needed.
 
Regards,
Andy_______________________________________________
