Starting JBoss 7.1.1 from eclipse fails

Question

When starting JBoss from the servers view inside Eclipse Indigo SR2 with JBoss Tools 2.3.0 on my machine, everything runs fine.

I have copied all contents of my work folder containing Eclipse and JBoss-7.1.1.Final to a different machine.

Now, when I try to start the server, it fails with this message:

Starting JBoss 7.1.1 Runtime encountered an error. The archive: /jboss/jboss-modules.jar which is referenced by the classpath, does not exist.

I don't see anything referencing the jar in the runtime or server or project configurations. And the jboss-modules.jar is inside the root folder of the JBoss server, as expected. There are no deployments in the standalone.xml. Both machines are running SuSe 12. .bashrc and .profile are empty.

The server starts fine from command line.

I have created a new runtime and a server using this runtime from scratch in Eclipse, but get the same error.

Any ideas are appreciated.

Answer 1

I have found the solution just now:

1. I have found the reference to the jboss-modules.jar in the launch configuration of the server under User Libraries. All attempts to delete it failed. After removing or resetting to defaults and applying, I started the server, received the same error and the .jar was in the launch cofig classpath again.
   
2. I actually had a project named jboss without any facets, just to have the JBoss files visible from the eclipse project browser. This project was closed.

After I opened it, the server started fine again.

I am still clueless about how the reference to the jboss-modules.jar from a project got into the launch config classpath and why it resisted removing attempts.

Answer 2

modules.jar is required to run JBOSS 7.1 Runtime, which is missing.

1. Go to Window > Preferences > Server > Runtime Environment > Default Classpath. If you don't see any classpath in the right side menu,you can tweek the classpath setting by-

   1. Change server to JBOSS 7.0 Runtime.
   2. Again Change server to JBOSS 7.1 Runtime.

Delete and Add Server Again,

while Add new server,

1. Please Check the 2nd and 3rd checkboxes
   -"Listen on all Interfaces to allow remote web connections"
   -"Expose your management port as server's hostname"

now everything will run fine.

Answer 3

I know this is a late response but in case anyone needs a solution to this issue.

If you go to Window > Preferences > Servers > Runtime Environments > Default Classpath

You will see that the 'JBoss 7.0 Runtime' does not have 'modules../-[*/.jar]' dependency, which is where the jboss-modules.jar lives. After selecting the 'JBoss 7.0 Runtime' rather than the JBoss 7.1 Runtime, the error relating to the jboss-modules.jar went away, and the server starts without error.

My application also started without error. I am using JBoss 7.1.1.
