Creating Entity EJB's in loop

Question

I have a servlet in my EAR that inserts default fields into a table based on one of my CMP Entity EJB's (v2.x).
The servlet operates as such:
public void init(ServletConfig config) throws ServletException {
     super.init(config);
     ServletContext application = getServletContext();
     Context ctx = null;
     AccountType act = null;
     AccountTypeHome acth = null;
     try{
          ctx = new InitialContext();
          Object obj = ctx.lookup(JNDI_USERPRIVELAGES);
          application.log("Creating system privelage groups...");
          UserPrivelages usp = null;
          UserPrivelagesHome usph = null;
          usph = (UserPrivelagesHome) PortableRemoteObject.narrow(obj,UserPrivelagesHome.class);
          usp = usph.create(new Integer(1),baseUserPrivelages[0][0],baseUserPrivelages[0][1],baseUserPrivelages[0][2]);
          UserPrivelages uspStandard = usph.create(new Integer(2),
               baseUserPrivelages[0][0],baseUserPrivelages[0][1],
                              baseUserPrivelages[0][2]);
          application.log("Created system privelage groups...");
          application.log("Creating system users...");
          Context ctx2 = new InitialContext();
          SysUserHome sysh = null;
          application.log("Looking up: "+JNDI_SYSUSER);
          Object o = ctx2.lookup(JNDI_SYSUSER);
          application.log("Narrowing object...");
          sysh = (SysUserHome) PortableRemoteObject.narrow(o,SysUserHome.class);
          for(int i=0;i<1;i++){
               String[] users = baseSysUsers;
               application.log("Creating: "+users[1]);
               Integer id =new Integer(users[0]);
               String login = users[1];
               String pword = users[2];
               String forename = users[3];
               String surname = users[4];
               String empNo = users[5];
               String priv = users[6];
               String group = users[7];
               String lastUpdatedBy = users[8];
               SysUser sys = null;
               application.log("Creating sysuser...");
               sys = sysh.create(id,login,pword,forename,surname,empNo,priv,group,new java.sql.Timestamp(System.currentTimeMillis()),lastUpdatedBy);
               application.log("Created "+users[1]);
          application.log("Created system users...");
     } catch(NamingException ne){
          application.log("Error initialising startup!",ne);
     } catch(RemoteException re){
          application.log("Error creating startup db entries.",re);
     } catch(CreateException ce){
          application.log("Error creating Sysuser",ce);
When the servlet starts, the first 2 ejbs are created without a problem. When it gets to the loop to create the SysUsers, it seems to create the first then throws the following exception:
Error creating startup db entries.
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
     java.rmi.RemoteException: Transaction aborted (possibly due to transaction time out).; nested exception is: javax.transaction.RollbackException; nested exception is:
     javax.transaction.RollbackException
java.rmi.RemoteException: Transaction aborted (possibly due to transaction time out).; nested exception is: javax.transaction.RollbackException; nested exception is:
     javax.transaction.RollbackException
javax.transaction.RollbackException
     <<no stack trace available>>The ejbCreate method for the SysUserBean interface is as follows:
     public Integer ejbCreate(Integer id,
     String login,
     String pword,
     String forename,
     String surname,
     String empNo,
     String privelage,
     String group,
     java.sql.Timestamp lastUpdated, String lastUpdatedBy) throws CreateException {
          System.out.println("Constructing new SystemUser with login: "+login);
          this.setSysu_id(id);
          this.setSysu_login_name(login);
          this.setSysu_password(pword);
          this.setSysu_forename(forename);
          this.setSysu_surname(surname);
          this.setSysu_forename(empNo);
          this.setSysu_user_privelage(privelage);
          this.setSysu_user_privelage(group);
          this.setSysu_last_updated(lastUpdated);
          this.setSysu_last_updated_by(lastUpdatedBy);
          System.out.println("Created new SystemUser: "+login);
          return null;
     }When I run the code, the servlet runs up until it calls sysh.create(...) where it throws the exception.
Inside the ejbCreateMethod, the whole method is run (as I have the "System.out.println('Created new SystemUser: '+login);" statement having been executed.
The "return null" statement at the end of the method doesn't seem to be the problem (it is a CMP) besides, I've tested it with returning the primary key (return this.getSysu_id()) but this makes no difference and I have the same implementation for the UserPrivelages interface.
The ejbCreate method in the UserPrivelagesBean class also has the same format without the error occurring.
I'm currently testing with the J2EE Application deployment tool 1.3.
Do I need to "close" (if such an option exists) the SysUser interface before I create a new one?

Found the problem. Too much late night programming. I double declared a couple of methods in the Create method on the SysUserBean class.
All working fine now.
