Error in deploying a cmp bean in j2ee 1.3

Question

Hi,
I am deploying a cmr application using 3 cmp entity beans. while deloyment i get a error for one of the entity bean, studentEJB. the error is :
For [ StudentEJB ]
Error: There are no method permissions within this bean [ StudentEJB ]. Transaction attributes must be specified for the methods defined in the remote interface [ LocalStudent ]. Method [ getLastName ] has no transaction attribute defined.
my LocalStudent file is:
import javax.ejb.*;
import java.util.*;
public interface LocalStudent extends EJBLocalObject
public String getStudentID();
public String getFirstName();
public String getLastName();
public ArrayList getAddressList();
public ArrayList getRosterList();
public void addAddress(LocalAddress address);
public void addRoster(LocalRoster roster);
while no errors are coming for the studentID and firstName fields why is the error coming for lastName field ?
three fields, studentID, firstName and lastName contain similar implementations in the LocalStudent and studentEJB class.
wiating for an early response...

Hello there!
I am having a similar problem here also. I am trying to build a lab for test the J2EE tecnology in order for the company I work for switch our Cash Dispenser system to java.
I have made a very simple entity EJB witch local interface is:
public interface LabLocal extends EJBLocalObject
String getExperiment();
String getDescription();
void setDescription(String description);
String getResult();
void setResult(String result);
Local home is:
public interface LabLocalHome extends EJBLocalHome
     LabLocal create( String experiment, String description, String result ) throws CreateException;
     LabLocal findByPrimaryKey( LabPK key ) throws FinderException;
     void remove();
and the bean itself is:
public class LabBean implements EntityBean
private EntityContext ctx;
private DataSource dataSource;
public String experiment;
public String description;
public String result;

I will omit the PK code in order to not create a longer than necessary post.
I am using the deploytool�s Graphical interface to generate a standalone jar file. When I run the verify tool I get the following errors:
For [ D:-Linux-Java-LabJar.jar#LabJar.jar#LabBean ]
Error: There are no method permissions within this bean [ LabBean ]. Transaction attributes must be specified for the methods defined in the remote interface [ simpleEJB.LabLocal ]. Method [ getDescription ] has no transaction attribute defined.

I�ve read the forum in search for an good answer and found some sugestions to look in the security and transaction tab in order to force the tool to generate the entries for the methods. It did not helped at all.
I tried to change the defaults in transaction tab from "required" to "mandatory". When I save, the tool presents the root screen of the jar file, but when I go check the values of the transaction atributes, they are again set to "required" .
In the descriptor viewer for the application descriptor it shows:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sun-ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Sun ONE Application Server 8.0 EJB 2.1//EN" "http://www.sun.com/software/sunone/appserver/dtds/sun-ejb-jar_2_1-0.dtd"> <sun-ejb-jar> <enterprise-beans> <name>LabJar</name> <unique-id>366779567</unique-id> <ejb> <ejb-name>LabBean</ejb-name> <jndi-name>LabBean</jndi-name> </ejb> </enterprise-beans> </sun-ejb-jar>
I cant get to edit it when I try.
I am using the "Deployment Tool for Java 2 Plataform Enterprise Edition 1.4" from the J2EE SDK 1.4_2 running on Windows 2000 SP4.
Tks in advance,
Leonardo.
P.S.: Ok. Isnt it silly. I wrote all that, and then choose "supported" instead of mandatory, saved and verified that it saved the setting indeed. returned to required and runned the test. It worked.
