CMP bean does not deploy -- need your advice

[Joseph Sweet]

Hello Friends,

I am trying to deploy a very simple CMP bean on JBoss with Hypersonic SQL database.

But it does not deploy. JBoss does not even give error messages, simply nothing. What am I missing?

Here is the jar file that I am trying to deploy.

Here is a zip file of the code.

Here is the code:

Catalog.java

 
package com.ejb;
 
import java.rmi.RemoteException;
import javax.ejb.*;
 
 
public interface Catalog extends EJBObject {
 
 
  public String getCatalogId() 
    throws RemoteException;
 
  public String getJournal() 
    throws RemoteException;
 
  public String getPublisher() 
    throws RemoteException;
 
   public void setJournal(String journal) 
    throws RemoteException;
 
  public void setPublisher(String publisher) 
    throws RemoteException;
 
}
 
 

CatalogHome.java

 
package com.ejb;
 
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
import javax.ejb.FinderException;
import java.rmi.RemoteException;
 
 
 
public interface CatalogHome extends EJBHome {
 
  
  public Catalog create(String catalogId)
    throws CreateException, RemoteException;
 
  public Catalog findByPrimaryKey(String catalogId)
    throws FinderException, RemoteException;
 
  
 
}
 
 

CatalogBean.java

 
package com.ejb;
 
import javax.ejb.*;
 
abstract public class CatalogBean implements EntityBean {
 
 
  private EntityContext ctx;
 
public CatalogBean() {};
 
 
  public void setEntityContext(EntityContext ctx) {
    
    this.ctx = ctx;
  }
 
 
  public void unsetEntityContext() {
    this.ctx = null;
   
 
  }
 
abstract public String getCatalogId();
abstract public void setCatalogId(String catalogId);
 
abstract public String getJournal();
abstract public void setJournal(String journal);
 
abstract public String getPublisher();
abstract public void setPublisher(String publisher);
 
  public void ejbActivate() {
      
  }
 
 
  public void ejbPassivate() {
    
  }
 
  
  public void ejbLoad() {
    
  }
 
  public void ejbStore() {
    
  }
 
  
  public void ejbRemove()
    throws RemoveException
  {
    
  }
 
  
  public String ejbCreate(String catalogId, String journal, String publisher)
    throws CreateException
  {
 
    setCatalogId(catalogId);
setJournal(journal);
setPublisher(publisher);
 
    return catalogId;  
  }
 
  
  public void ejbPostCreate(String catalogId)
  {
    
  }
 
 
 
}

That jar does not have the correct packaging. This is what the jar contains:

META-INF/
META-INF/MANIFEST.MF
production/com/
production/com/ejb/
production/com/ejb/Catalog.class
production/com/ejb/CatalogBean.class
production/com/ejb/CatalogHome.class
production/META-INF/
production/META-INF/ejb-jar.xml
production/META-INF/jboss.xml
production/META-INF/jbosscmp-jdbc.xml

Notice that a META-INF folder has been created *inside* the "production" folder and all the xml files (which are necessary for recognizing the jar as an ejb jar) are placed here.

The correct packaging should look like:

META-INF/
META-INF/MANIFEST.MF
[B]META-INF/ejb-jar.xml
META-INF/jboss.xml
META-INF/jbosscmp-jdbc.xml
[/B]production/com/
production/com/ejb/
production/com/ejb/Catalog.class
production/com/ejb/CatalogBean.class
production/com/ejb/CatalogHome.class

This will help JBoss to identify this as an ejb jar and then process it for deploying.

Yes Jaikiran is right.

Also your jar has a production folder, but your package name is "com.ejb" so I doubt if Jboss can find the classes

Why don't you create an EAR and have proper packaging as specified in the specs. Have APP-INF/Class and all your classes inside it.

[Joseph Sweet]

Thank you guys, you were right.

JBoss did not identify the ejb-jar.xml thus did not start the deployment. I also had a little mistake with the Home interface's create() method signature but I could see it by the error output once the deployment occurred.

BTW, what is APP-INF directory? I have never heard of something like that.

Is it vendor-specific?

Yes. My bad, this is specific to weblogic server.
