hello
i generate a cmp ejb automatically by using jb6,it map to the jobs table of
pubs database within the mssqlserver2000,as follow:


     local interface: Jobs.class
 localhome interface: JobsHome.class
    remote interface: JobsRemote.class
remotehome interface: JobsRemoteHome.class
implementation class: JobsBean.class

after that,i create a  test program by using the "test client wizard" in
jb6,as follow:

package jobentity;

import com.mansion.ejb.entity.*;
import javax.naming.*;
import javax.rmi.PortableRemoteObject;

public class JobsTestClient1 {
  private JobsRemoteHome jobsRemoteHome = null;


  public JobsTestClient1() {
    try {
            Context ctx = new InitialContext();

            Object ref = ctx.lookup("JobsRemote");

          jobsRemoteHome = (JobsRemoteHome) PortableRemoteObject.narrow
(ref,JobsRemoteHome.class);
    }
    catch(Exception e) {
      e.printStackTrace();
    }
  }

  public JobsRemoteHome getHome() {
    return jobsRemoteHome;
  }

  public static void main(String[] args) {
    JobsTestClient1 client = new JobsTestClient1();
    try{
      JobsRemote jobsRemote=client.getHome().findByPrimaryKey(new
Integer(1));
    }catch(Exception e){
      System.out.println(e.getMessage());
    }
  }
}



when i run the test program,it tell me "Must call within a valid 
transaction
context",as follow:
