HI,

everybody,my appliaction is ejb2.0 ,container jboss405,migrate from weblogic92,but the transaction problem puzzle me for a long time

public static UserTransaction getUserTransaction() throws NamingException,Exception {
 if (fooTransaction != null)
 return fooTransaction;

 UserTransaction tran = null;
 try {
 Context ic = getInitialContext();
 if (ic != null) {
 tran = (UserTransaction) ic.lookup("UserTransaction");
 // tran = (UserTransaction) ic.lookup("java:/UserTransaction");
 }
 if (tran == null) {

 throw new Exception("UserTransaction is null!");

 }
 } catch (NamingException ex) {
 System.out.println("catch NamingException when trying to lookup UserTransaction name\n"+ ex.toString());
 throw ex;
 } finally {
 }
 return tran;
}

[code
in the oracle-ds.xml:


<jndi-name>jdbc/mydatasource</jndi-name>
<use-java-context>false</use-java-context>



but when i invoke ejb on my client,a exception happen:

2008-07-16 10:40:29,718 INFO [STDOUT] catch NamingException when trying to lookup UserTransaction name

and another problem ,how does everybody solve the datasource 'java.lang.ClassCastException: javax.naming.reference' when I do this:

ds = (javax.sql.DataSource) ic.lookup("jdbc/mydatasource");



to avoid the effect of tomcat ,I make some changes as below:
at $JBOSS_HOME/server/default/deploy/jbossweb- tomcat55.sar/META-INF/jboss-service.xml
changes the UseJBossWebLoader's attribute to true

<attribute name="UseJBossWebLoader">true</attribute>



but it doesn't work, I don't konw how to do it
could anyone please look in.....
thanks a lot
