Hi everybody,

When I try to publish one simple web project in tomcat 7 server, the wtp gives me a nullpointer with the following stacktrace:

java.lang.NullPointerException
	at org.eclipse.wst.server.core.util.PublishHelper.publishSmart(PublishHelper.java:331)

	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:53)


I have tried to remove server and add again, even update eclipse!

This error never happens to me before, can you help-me?

Sorry for my bad english.

It's not clear exactly what scenario brings about this NPE. Does
right-clicking on the Tomcat 7 server in the Servers view and executing
"Clean..." able to get past this error?

Cheers,

So, when I do this, the same NPE occurs. I tried to re-build the project and clean de work directory of tomcat too. Nothing of this actions works for me.

Thank you for the answer!

I've inspected the code and I have no good guesses as to what is causing
you to encounter the NPE. It's not something I've ever seen. The stack
trace indicates that you have selected "Use Tomcat installation...". Do
you get the same behavior with "Use workspace metadata..."?

Cheers,
Larry
