Glassfish return java.lang.NoClassDefFoundError when deploying while using library from external JAR

[Ace David]

Hi guys,

I am currently developing an application using Glassfish v3 and Netbeans IDE 6.9 and currently having issues. I have an Enterprise Application project which consist of a project-ejb and project-war. I am trying to use an external library/har from the project-ejb.

In the project-ejb, I added the external library/jar using Properties > Libraries > Compile and used it on one of my session beans. The problem is that the server always return an error after I declared the variable that is using the library and deployed the project.

   
package com.org.test;

import com.ext.ExternalLibrary;

@Singleton
@LocalBean
public class TestSessionBean {
    ExternalLibrary extLib;

   public void someMethod(){
   }
}

SEVERE: Class [ Lcom/ext/ExternalLibrary; ] not found. Error while loading [ class com.org.test ]
WARNING: Error in annotation processing: java.lang.NoClassDefFoundError: Lcom/ext/ExternalLibrary;
org.glassfish.deployment.common.DeploymentException: java.lang.NoClassDefFoundError: Lcom/ext/ExternalLibrary; 
        at org.glassfish.weld.WeldDeployer.event(WeldDeployer.java:167)
        .
        .

Compilation works fine but deployment does not. The weird thing is that when I use the external library from the project-war, it just deploys fine and it can use it properly. Please advise on what I am doing wrong. I have searched the forum thoroughly for solutions but it seems that I am the only one who cannot solve the problem. Thanks!

Regards,
Ace

After scouring google, I finally found a solution to a certain problem but tried it anyway. I just have to put the libraries in this directory: <glassfish_home>/domains/domain1/lib
