[JBoss-user] [Persistence, JBoss/CMP, Hibernate, Database] - How to use a primary Key CMP field in CMR?

2006-06-15 Thread jbossACM 
Hi,

I'm trying to use a Primary Key CMP field in a CMR relationship. 

This CMP field is part of a composite primary key within the entity bean where 
I define the CMR relationship. The declaration within the EJB is as follows:


  | /**
  |  * @ejb:persistent-field
  |  * @ejb:pk-field
  |  * @ejb:interface-method
  |  *
  |  * @jboss.column-name name="native_service_unit"
  |  */
  | abstract public String getNativeServiceUnitId();
  | 
  | /**
  |  * @ejb:interface-method
  |  * @ejb:relation
  |  *name="NativeServiceUnit-NativeCategory"
  |  *role-name="many-nativecategory-has-one-nativeserviceunit"
  |  *
  |  * @jboss.relation
  |  *fk-column="NATIVE_SERVICE_UNIT"
  |  *related-pk-field="nativeServiceUnitId"
  |  */
  |abstract public NativeServiceUnitLocal getNativeServiceUnit();
  | 

The corresponding generated XML segments are:

jbosscmp-jdbc.xml: 
< entity >


  | 
  |  NativeCategory
  | 
  |  NATIVE_CATEGORY
  | 
  |  
  | nativeCategoryId
  | native_category_id
  | 
  | 
  |  
  | nativeServiceUnitId
  | native_service_unit
  | 
  | 
  | 
  | 

jbosscmp-jdbc.xml: 



  | 
  |   
NativeServiceUnit-NativeCategory
  | 
  |   
  |   
many-nativecategory-has-one-nativeserviceunit
  |   
  | 
  |   
  |   
  |   
one-nativeserviceunit-has-many-nativecategory
  |   
  |  
  |nativeServiceUnitId
  |NATIVE_SERVICE_UNIT
  |  
  |   
  | 
  |   
  | 
  | 

The problem is that when I try to create an entity, I get the following error:

  | 2006-06-15 15:41:17,312 ERROR 
[org.jboss.ejb.plugins.cmp.jdbc.JDBCCreateEntityCommand.NativeCategory] Could 
not create entity
  | java.sql.SQLException: Column 'native_service_unit' specified twice
  | 

Is there any workaround to this situation? I know that this works well on other 
servers.

Thanks!

[JBoss-user] [JNDI/Naming/Network] - How to change UserTransaction JNDI name?

2006-06-15 Thread jbossACM 
Hi,

I'm performing a migration from Weblogic Server to Jboss. Throughout my 
application I obtain explicit transactions as follows:

transaction = (UserTransaction) ctx.lookup("javax.transaction.UserTransaction");

Whereas in Jboss it seems to be:

transaction = (UserTransaction) ctx.lookup("UserTransaction");

Is there any way to change this default JNDI name?

Thanks!
