rest - Jersey 1.18.1 is unable to pick my restful service when deployed on Jboss 7.1.1 final

Question

I have a very confusing problem with me. I have a eclipse Restful service project which is being built by gradle. I can successfully build and run my application in Tomcat 7.0.54, from within Eclipse and by deploying the war directly in /webapps folder of Tomcat.

But when I deploy my same war in Jboss 7.1.1 Final, it gives me below error.

Moreover, when I unpack this war to a folder and deploy that folder inside Jboss, it works! It also works if I run my project in Jboss directly from Eclipse. However, if I export the project as a war (from eclipse) and deploy that war file into Jboss, it again gives me same problem.

When I drilled down into the the code of Jersey, I found that com.sun.jersey.core.spi.scanning.uri.FileSchemeScanner is not able to pick my class files from the war.

Please help us resolve this issue.

Answer 1

I found the solution, and would like to post it so someone else could benefit. The problem was there in our build script. We were using different version of Jersey libraries. For some of the libraries, version 1.18.1 was being used, while for some other version 1.18 was being used.

Once the version for all the libraries was updated to 1.18.1, it worked perfectly.
