Eclipse : Running command line to EJB inside Eclipse

I'm running Eclipse Europa (the J2EE package).

See the previous post about running a command line Java program inside a DOS box and the million paths etc. you have to set up.

It's a lot easier to run it inside Eclipse by right clicking the application in the Package Explorer and selecting "Run As" / "Java Application".

(Note : JBoss needs to be started first by selecting the Server view inside the J2EE perspective , right click, "Start".)

You get this error in the console:

Need to specify class name in environment or system property, or as an
applet parameter, or in an application resource file: java.naming.factory.initial

As per the previous post, the solution then was to add a path to the jndi.properties file:

set CLASSPATH=C:\JBoss-4.0.5.GA\server\default\conf;%CLASSPATH%

In Eclipse, however, go "Project Properties" / "Run/Debug Settings" / select the launch configuration / "Edit" / click on the "Classpath" tab / "Advanced: / "Add External Folder" and then browse to the jndi.properties folder as above and "OK" out.

That's it - Eclipse takes care of all the other stuff!

Enjoy!

EJB : Running a command line client to a JBoss EJB

The EJB example running on JBoss is taken from the WTP (Web Tools Project) tutorials here plus XDoclet - all inside Eclipse.

Call the package ejbs.

We have an EJBTestBean:

 /** 
  *
  *  
  * @ejb.interface-method view-type="remote"
  *  
  * @generated
  *
  * //TODO: Must provide implementation for bean method stub
  */
 public String greet(String param) {
  return "Hi dude " + param;
 }

XDoclet creates all the Home and Util stubs.

Now we want to test this from a Java command line client.

So we create a Java class with a main() method (called CLTestClient):

try 
  {
   EJBTestHome home = ejbs.EJBTestUtil.getHome();
   EJBTest service = home.create();
   String result = service.greet("Tom");
   System.out.println();
   System.out.println("Result is " + result);
  }
  
  catch (Exception e)
  {
   System.out.println();
   System.out.println("Exception " + e.getMessage());
  }

and we want to test from the command line:

java CLTestClient

and we get ClassNotDefined all over the place.

So we add the EJB files to the CLASSPATH:

set CLASSPATH=C:\JBoss-4.0.5.GA\
server\default\lib\jboss-j2ee.jar;C:\your path\EJBTestClient\build\classes;C:\your path\EJBTestClient\build\classes\ejbs;%CLASSPATH%

Then we get this error:

Need to specify class name in environment or system property, or as an
applet parameter, or in an application resource file: java.naming.factory.initial

The solution is to add a path to the jndi.properties file:

set CLASSPATH=C:\JBoss-4.0.5.GA\server\default\conf;%CLASSPATH%

More ClassNotDefined errors:

set CLASSPATH=C:\JBoss-4.0.5.GA\client\jbossall-client.jar;C:\JBoss-4.0.5.GA\lib\jboss-common.jar;C:\JBoss-4.0.5.GA\server\default\lib\jboss.jar;C:\JBoss-4.0.5.GA\client\jnp-client.jar;C:\JBoss-4.0.5.GA\client\jboss-client.jar;%CLASSPATH%

and finally:

java CLTestClient

returns:

Result is Hi dude Tom

By the way, if you wanted to do this from a browser inside a jsp page:

LT%@page import="ejbs.EJBTestUtil"%GT
LThtmlGT
LTheadGT
LTtitleGTEJBWebTestLT/titleGT
LT/headGT
LTbodyGT
LT%
 ejbs.EJBTest tb = null;

 try
 {
  ejbs.EJBTestHome home = EJBTestUtil.getHome(); 
  tb = home.create();
 }
 
 catch(Exception exception)
 {
    
 }
 
%GT

LTbGTLT%= tb.greet("Tom") %GTLT/bGT

LT/bodyGT
LT/htmlGT

Where LT = "less than" and GT = "greater than".

Enjoy!
