Help with exception calling cmp entity bean from session bean

Question

Hi,
I know someone else posted a very similar problem recently but I think the root of my problem may be different.
This is the exception that I receive:
javax.transaction.TransactionRolledbackException: CORBA TRANSACTION_ROLLEDBACK 9998 Maybe; nested exception is:
org.omg.CORBA.TRANSACTION_ROLLEDBACK: vmcid: 0x2000 minor code: 1806 completed: Maybe

This is my primary key implementation:
public final class SecurityUserKey implements java.io.Serializable {
public java.lang.Integer userId;
public java.lang.Integer roleId;
public java.lang.String emailAddress;
     * Creates an empty key for Entity Bean: SecurityUser
     public SecurityUserKey() {
* @see java.lang.Object#equals(java.lang.Object)
public boolean equals(java.lang.Object otherOb) {
if (this == otherOb) {
return true;
if (!(otherOb instanceof itsthes.security.entitybeans.SecurityUserKey)) {
return false;
itsthes.security.entitybeans.SecurityUserKey other = (itsthes.security.entitybeans.SecurityUserKey) otherOb;
return (
(userId==null?other.userId==null:userId.equals(other.userId))
(roleId==null?other.roleId==null:roleId.equals(other.roleId))
(emailAddress==null?other.emailAddress==null:emailAddress.equals(other.emailAddress))
* @see java.lang.Object#hashCode()
public int hashCode() {
return (
(userId==null?0:userId.hashCode())
^
(roleId==null?0:roleId.hashCode())
^
(emailAddress==null?0:emailAddress.hashCode())
My entity method invocation is this:
public Collection findUserRoles() {
Vector userCollection=new Vector();
try {
Context jndiContext = new InitialContext();
LocalSecurityUserHome home = (LocalSecurityUserHome) jndiContext.lookup(this.securityUserBean);
Iterator i = home.findAll().iterator();
while ( i.hasNext() ) {
LocalSecurityUser securityUser = (LocalSecurityUser)i.next();
SecurityUser sessionBean=mapLocalSecurityUser(securityUser);
userCollection.add(sessionBean);
} catch (javax.naming.NamingException e) {
System.err.println(e);
} catch (javax.ejb.FinderException e) {
System.err.println(e);
return userCollection;
If anyone could point me in the right direction that would be great.
thanks,
William

Hi,
The Transaction Rollback exception may be due to the SystemException thrown in your findUserRoles() code which force the container to rollback the transaction. catch the generic exception in your findUserRoles() code and veriy what went wrong.
i hope this helps.
