Libraries missing when deploying enterprise application

[naranha]

i'm using netbeans 6.8 to develop java ee 6 application with glassfish 3. My problem is, when I deploy my Web-Application everything works fine, however when I deploy my webapplication as part of my enterprise application, some libraries (like struts) are missing and glassfish throws errors. most libraries are there, but not all of them. any idea how to solve this?

- I have an Enterprise App, which at the moment has one web module
- deploying the web-module alone works fine
- the projects ear file contains nearly all .jar-files, but some are missing

Build output:
Initial deploying <project> to /home/<user>/NetBeansProjects/<project>/<project>/dist/gfdeploy/<project>
Completed initial distribution of <project>
Initializing...
deploy?path=/home/<user>/NetBeansProjects/<project>/<project>/dist/gfdeploy/<project>&name=<project>&force=true failed on GlassFish v3
/home/<user>/NetBeansProjects/<project>/<project>/nbproject/build-impl.xml:257: The module has not been deployed.
BUILD FAILED (total time: 12 seconds)

glassfish3 output:
INFO: [ERROR] 00:27 (ActionServlet.java:init:364)
Unable to initialize Struts ActionServlet due to an unexpected exception or error thrown, so marking the servlet as unavailable. Most likely, this is due to an incorrect or missing library dependency.

Interestingly it works if I copy the struts-1.2.9.jar file to the <proj>/dist/gfdeploy/<proj>/lib directory, while the project is building.

I switched to a maven2 based architecture now, something I wanted to do sooner or later anyway. It works fine and I get no more missing library errors.
