Re: [JBoss-user] Urgent, May someone tell me how JBoss realize a Transaction?

[Edward Wang]

My Bean is a BMP entity bean, and I have already set the 
<persistence-type>Bean</persistence-type> in ejb-jar.xml.
In my impression, <transaction-type> </transaction-type>  is only needed in the 
ejb-jar.xml for a Session Bean?

Better if someone could send me a BMP entitybean .jar file with the source code that 
really works with transaction
on JBoss+Tomcat. All of us knows, that the poor documentation and examples of JBoss 
frustrated us too much. 
May any of you do me the favour? Thanks a lot!!!!!!!

Below is my ejb-jar.xml file:
<?xml version="1.0" encoding="UTF-8"?>

<ejb-jar>
  <description>zee120 Bean</description>
  <display-name>zee120BeanHome</display-name>
  <enterprise-beans>
    <entity>
  <ejb-name>zee120BeanHome</ejb-name>
  <home>com.edward.MSTMT.Entity.zee120.zee120BeanHome</home>
  <remote>com.edward.MSTMT.Entity.zee120.zee120</remote>
  <ejb-class>com.edward.MSTMT.Entity.zee120.zee120Bean</ejb-class>
  <persistence-type>Bean</persistence-type>
  <prim-key-class>com.edward.MSTMT.Entity.zee120.zee120BeanPK</prim-key-class>
 </entity>
  </enterprise-beans>
</ejb-jar>

below is the jboss.xml:
<?xml version="1.0" encoding="UTF-8"?>

<jboss>
  <enterprise-beans>
     <entity>
       <ejb-name>zee120BeanHome</ejb-name>
       <jndi-name>zee120BeanHome</jndi-name>
     </entity>
  </enterprise-beans>
</jboss>


Thanks in advance.

Edward

Is your entity ben CMP or BMP, i.e. in your ejb-jar.xml file what's your 
<transaction-type> </transaction-type> value?

Now I am using JBoss+Tomcat 2.22 pack.

I setup a Datasource that connect to SQLServer 7.0 with the JDBC Driver of WebLogic 
(BEA Sys, a Type 4 Driver).
And in my Client Class that calls an EJB (Entity), I use the 
"javax.transaction.UserTransaction", it seems JBoss
can not find the name in it's Context. Then I use a TxManager class in the following 
way:

  TxManager tx = null;

  try {
   tx = org.jboss.tm.TxManager.getInstance();
   tx.begin();
 
   zee120Beanhome home = getHome();
   zee120BeanPK pk = new zee120BeanPK("001");
   zee120 cli = home.findByPK(pk);
   
   cli.remove();

   tx.commit();
  } catch (Exception e) {
    tx.rollback();
  }

The record "001" is expected to exist in my DB still if some error occurs, but the 
result is it was removed.

How can I use Transaction with JBoss?

Thanks for your help.
