Description Udo Walker CLA 2008-06-03 07:26:47 EDT 
Build ID: M20071023-1652

Steps To Reproduce:
1. IProgressMonitor monitor = new NullProgressMonitor();
2. IProject project = ... some web project.
3. EARArtifactEdit edit = new EARArtifactEdit(project,false);
4. edit.setWebContextRoot(project,"test");
->NPE


More information:
The variable edit contains after line 3 a not null reference value.
Line 4 creates a null pointer exception.

I also do not understand why I need a project to create the EARArtifactEdit and when I want to set the web context root I need the project again?

I don't know how to set the web context root otherwise.
Comment 1 Carl Anderson CLA 2008-06-03 12:13:30 EDT 
Udo, do you just have a standalone Web project, that you want to set the Context Root for?  Or is this Web project a member of an EAR?  And is it a Servlet 2.5 Web module?  Or Servlet 2.4 or earlier?
Comment 2 Carl Anderson CLA 2008-06-03 12:15:39 EDT 
Also, if the project in step 2 is a web project, it should not be passed into EARArtifactEdit's constructor - that is for EAR projects.  (So this would appear to be a usage problem.)
Comment 3 Udo Walker CLA 2008-06-04 06:02:19 EDT 
The project facets are:

Dynamic Web Module 2.5
Java 6.0
Comment 4 Udo Walker CLA 2008-06-04 06:03:12 EDT 
How can I change the context path of a "not EAR" web project?
Comment 5 Carl Anderson CLA 2008-08-06 09:30:18 EDT 
The appropriate way to set the context root for a Web project is via

J2EEProjectUtilities.setServerContextRoot(webProject, contextRoot);

While J2EEProjectUtilities is an internal class, it is used extensively by both WTP code and adopters.  If requested, an API can be created to access this.

I am lowering the severity of this bug for now.

Hi Carl,

a public API for setting the context root would be great!
Comment 7 Carl Anderson CLA 2008-08-06 10:46:16 EDT 
The proper place to put this would be in WebUtilities.
