the code of stateless session bean is :-
| try{
| initial = new InitialContext ();
| logger.debug("before lookup");
| groupsHome = (GroupsLocalHome) initial.lookup
("java:/comp/env/ejb/GroupEJB");
| logger.debug("After lookup");
| logger.debug("group id = " +userLocal.getGroupID());
| GroupsLocal gLocal =
groupsHome.findByPrimaryKey(userLocal.getGroupID());
| logger.debug("After find " );
| logger.debug("the class name = " + gLocal);
|
| String str = gLocal.getGroupName();
|
here in this code when i try execute last line (glocal.getGroupName())
then the exception occurs ... even i ahd checked my deployment descriptor also
...everything is alright and the bean which i'm calling is also having the proper
getter and setter meathod in its EJB and Local classes ...
but then also i'm not able to find that why it is throwing this error ....
why it is not getting the CMP feilds ....
deployment descriptors are :-
|
| ejb-jar
| <ejb-name>GroupEJB</ejb-name>
|
<local-home>com.le.nms.persistence.security.GroupsLocalHome</local-home>
| <local>com.le.nms.persistence.security.GroupsLocal</local>
|
<ejb-class>com.le.nms.persistence.security.GroupsBean</ejb-class>
| <persistence-type>Container</persistence-type>
| <prim-key-class>java.lang.Integer</prim-key-class>
| <reentrant>True</reentrant>
| <cmp-version>2.x</cmp-version>
| <abstract-schema-name>Groups</abstract-schema-name>
| <cmp-field>
| <field-name>groupID</field-name>
| </cmp-field>
| <cmp-field>
| <field-name>groupName</field-name>
| </cmp-field>
|
| jbosscmp-jdbc----------
|
| <ejb-name>GroupEJB</ejb-name>
| <table-name>groups</table-name>
| <cmp-field>
| <field-name>groupID</field-name>
| <column-name>GroupID</column-name>
| <auto-increment/>

| <entity-command name="mysql-get-generated-keys"/>
| <cmp-field>
| <field-name>groupName</field-name>
| <column-name>GroupName</column-name>
| </cmp-field>
|
