when running any web application, I always got the following error:
WARNING: Context path from ServletContext:/example differs from path from bundle: example.
That cause actionListeners not called from any implicitly returned form (a form that retrieved as ajax response).

This sounds like a problem in your own application and not a NetBeans IDE defect. If I misunderstood you please provide steps to perform in the NetBeans IDE to reproduce the defect and what is expected behaviour. Thx.

I too have experienced this exact issue. My project was working before with no issues whatsoever then one day I came back to the project; tried to run it in debug mode (so that I could see what a client was passing to the web service) and it would no longer deploy. I do note however that this seems to be an issue with the Glassfish 4 server. My project is located here: https://github.com/sylnsr/docx4j-ws

I resolved my issue. I am using Intelli-J. I checked the project settings and found the issue there. The project always used to was when the Artifact Type was set to WAR Exploded. For some reason is was set to WAR (not exploded). I switched it back to Exploded and the app deployed fine. I suspect that you are using Glassfish and that your Netbeans project configuration may have the same issue (just guessing).

For the record, this is a horrible red herring that Glassfish4 throws.

Correction: The particular application referenced run when the Artifact Type is "JavaEE Application: Exploded"

AFAICT, NetBeans deploy project in exploded form. But it should be relatively simple to narrow this issue down to a reproducible test case.

Btw. is there an issue filed for GF server in their bugzilla? Could you add a link here to the issue if you know it? Thanks.

I got rid of the message by removing the leading slash from the context root (defined in glassfish-web.xml in a simple web application or in application.xml in an EAR).

Source for the log entry is RealmAdapter.getAppContextID(final ServletContext servletContext): https://java.net/projects/glassfish/sources/svn/content/trunk/main/appserver/security/webintegration/src/main/java/com/sun/web/security/RealmAdapter.java
