Also reproducible in the latest 7.3.1 build.

Is this issue really new? I guess this might be reproducible even in 7.3.

You are right, this was also a problem in 7.3 - just reproduced. In the light of that, I think we can waive this for NB 7.3.1, if Jirka agrees. Adding 731-not-a-stopper.

I agree it is not a stopper for 7.3.1.

This is unrelated to the Maven. Creating Ant web project, changing context path and then following steps from description results in the same problem.
Although not sure yet where exactly should it be fixed. Need to investigate further..

I have improved server recognition in Maven web projects a little bit (web-main #578000e13c1e) and now it behaves identical to the Ant based projects.

The rest of the problem needs to be evaluated/fixed on Glassfish side. glassfish.eecommon.api.config.GlassfishConfiguration.getContextRoot() does not return correct value when it's called from j2ee.deployment.config.ConfigSupportImpl.getWebContextRoot() : line 266

Targeting to 7.4. I'm quite busy with other issues now but this should be fixed before release.

I can't reproduce this issue with latest Dev build. Petr, please can you try it too? Looks like ti's working fine.
I did some change into context root code last week. Maybe it resolved this issue too.

1. Create Ant web app with GF4
2. Go to project properties and set context root to /this-is-reproducible
3. Shut down IDE
4. Start IDE with clean userdir
5. Open the project
6. Project is missing server, resolve the problem by registering GF4
7. Go to project properties, Run subcategory

--> Context root shows /WebApplication1 instead of /this-is-reproducible

org.netbeans.modules.glassfish.eecommon.api.config.GlassfishConfiguration

   protected FileObject getSunDD(File sunDDFile,
           boolean create) throws IOException {
        if (!sunDDFile.exists()) {
            if (create) {
                createDefaultSunDD(sunDDFile);
            } else {
                return null;
            }
        }
        return FileUtil.toFileObject(sunDDFile);
    }

Here seems to be source of our problems - primarySunDD points to /tmp/WebApplication1/web/WEB-INF/sun-web.xml but there is glassfish-web.xml instead.

This is being initialized in GlassfishConfiguration costructor:
            this.primarySunDD = moduleHelper.getPrimarySunDDFile(module);

Looks like J2eeModuleHelper has 2 sources of configuration:

    public static final J2eeModuleHelper getSunDDModuleHelper(
            Object type) {
        return helperMap.get(type);
    }

    public static final J2eeModuleHelper getGlassfishDDModuleHelper(
            Object type) {
        return gfhelperMap.get(type);
    }

getSunDDModuleHelper is old GF v2 config and getGlassfishDDModuleHelper is v3/v4 config with WEB-INF/glassfish-web.xml.
This is being selected in Hk2ModuleConfigFactory. But without server GF v2 version is selected.

Added code into Hk2ModuleConfigFactory.create(J2eeModule module) to check for WEB-INF/glassfish-web.xml file and if exists, select proper v3/4 config.
Also create(final @NonNull J2eeModule module,
final @NonNull String instanceUrl) was modified to rely on new Tooling Library code and compare real server version instead of internal URI which is just a key here.

Checked into web-main:

changeset:   259121:e971252d9895
summary:     #228939 - Context path from glassfish-web.xml not reflected
             if the project is opened before the server is registered

Please don't close the issue until the changeset is pushed to the repository. I tried to reproduce it with todays build, it wasn't working and then I found out that the revision is not in web-main yet. It's hard to verify the fix if the bug is closed in BZ but it's not obvious when it will be part of the build. Thanks

Will push in 5 minutes after all bugs are updated.

Integrated into 'main-silver', will be available in build *201307252300* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Works fine, thanks
