为什么在使用远程应用程序库部署ejb模块时，Wildfly 8.1.0最终返回java.lang.NoClassDefFoundError：，但是glassfish没有？

Question

I tried to create a simple EJB remote client sample but I keep getting java.lang.NoClassDefFoundError: any time I tried to deploy the EJB.

The Remote Java Library File Structure is:

 > TestRemoteInterface --Source Package -- bean --TestBeanRemote.java -- Libraries -- Java EE 6 API Library --JDK 1.8 

The EJB Module File Structure is:

 > TestEJBModule --Source Package -- bean --TestBean.java -- Libraries -- TestRemoteInterface – dist/TestRemoteInterface -- Java EE 6 API Library -- JDK 1.8 

TestBeanRemote.java

package bean;
import javax.ejb.Remote;

@Remote
public interface TestBeanRemote {

    String getName(String name);

}

TestBean .java

package bean;

import javax.ejb.Stateless;

@Stateless public class TestBean implements TestBeanRemote {

 @Override public String getName(String name) { return "Here is my " + name; } } 

Question: When I try to deploy the TestEJBModule on get the follow log:

WARN [org.jboss.modules] (MSC service thread 1-6) Failed to define class bean.TestBean in Module "deployment.TestEJBModule.jar:main" from Service Module Loader: java.lang.LinkageError: Failed to link bean/TestBean (Module "deployment.TestEJBModule.jar:main" from Service Module Loader)

When I tried to deploy this same sample with Glassfish 4. It works fine.

NB: I am using netbeans 8.0.1

There appear to be a similar thread but it didn't help much. Thank you in advance.

Answer 1

I solved this problem by deploying the TestRemoteInterface jar to the sever first. Then I added it to the project manifest.mf as a dependency.

example:

Dependencies: deployment.TestRemoteInterface.jar

Another option if you are using maven is the use maven dependencies manifest

<configuration>
   <archive>
      <manifestEntries>
         <Dependencies>TestRemoteInterface.jar</Dependencies>
      </manifestEntries>
   </archive>
</configuration>
