How to call method of one EJB3.0 project in another EJB3.0 project

Question

Hi,
I would be thankful if someone could help me in this -
I am using SAP Netweaver 7.2 and have two EJB3.0 projects.
Now I am trying to instantiate a class of one EJB project into another and when I get a run time exception as -
javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError
I have tried to add it under the Java Build Path -> Projects but it only helps during compile time.
I have also tried checking the projects under "Project References" but it still gives the same problem
Here is the code and where exactly its failing -
import java.util.ArrayList;
import java.util.logging.Logger;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;
import org.csagroup.wsecomm.OrderSearch;
import org.csagroup.wsecomm.SalesOrderSearchQueryInImplBean;
import VendaOrders.ServiceClientImpl;
import com.sap.scheduler.runtime.JobContext;
import com.sap.scheduler.runtime.JobParameter;
import com.sap.scheduler.runtime.mdb.MDBJobImplementation;
import com.sap.xi.appl.se.global.SalesOrderID;
* Message-Driven Bean implementation class for: HelloWorldBean
@MessageDriven(
          activationConfig = {
                    @ActivationConfigProperty(propertyName = "messageSelector", propertyValue = "JobDefinition='HelloWorldJob'"),
                    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") })
public class HelloWorldBean extends MDBJobImplementation {     
     * @see MessageListener#onMessage(Message)
     public void onJob(JobContext ctx) {
         Logger logger = ctx.getLogger();
         logger.info("Hello World Testing onJob().....");
         try
              logger.info("Before Order Search...");
              OrderSearch os = new OrderSearch();   *// this is where it fails*
              logger.info("Before os...");
              SalesOrderID salesOrderIdBeginRange = new SalesOrderID();
              logger.info("Before salesOrderIdBeginRange...");
              salesOrderIdBeginRange.setValue("1");
              logger.info("After setValue(1)");
              SalesOrderID salesOrderIdEndRange = new SalesOrderID();
              logger.info("Before salesOrderIdEndRange");
             salesOrderIdEndRange.setValue("99999");
             logger.info("After 99999");
             os.setBeginRange(salesOrderIdBeginRange);
             os.setEndRange(salesOrderIdEndRange);
             SalesOrderSearchQueryInImplBean salesOrderSearchQueryInImplBean = new SalesOrderSearchQueryInImplBean();
             logger.info("After salesOrderSearchQueryInImplBean");
         } catch (Exception e){logger.info("Exception is...." + e.getLocalizedMessage());}
        // TODO Auto-generated method stub
I am able to see the message in my logs till "Before Order Search.." and fails when I try to instantiate OrderSearch class which is in another EJB 3.0 project.
Thanks for the help in advance.

Hi,
I am not sure if my posting was in readable format.
As soon as try to add the code, all the formatting is lost.
I would explain once again - My code is generated by the webservice "Generate Client code" i.e using WSDL into an EJB 3.0 Project. Now I am trying to call a method of the bean which takes a class object (OrderSearch) as the parameter.
When I am trying to instantiate this OrderSearch class in my another EJB3.0 project its failing.
Safter- Thanks for your reply but can someone help me who has worked on a similar issue.
Thanks,
Shiv
