Is your entity ben CMP or BMP, i.e. in your ejb-jar.xml file what's your <transaction-type> </transaction-type> value?   SAINT-MARTIN Cecile [EMAIL PROTECTED] -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]De la part de Edward Wang Envoy�� : mercredi 11 juillet 2001 11:12 À : JBoss Objet : [JBoss-user] Urgent, May someone tell me how JBoss realize a Transaction? 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.
