Hi,
Here's a strange bug. I have some MBean code that does our system
initialisation for us. On startup of JBoss (Version 3.0.5), it gets a
TransactionRolledBackLocalException.
However, if I redeploy our EAR, then it runs with no problems. I guess
that I need to add another dependency. But what should I add?
Here's the JBoss-service.xml
<?xml version="1.0" encoding="UTF-8"?>
<server>
<mbean code="xcom.traxbahn.system.TraxbahnManagement"
name="TIPS:service=TraxbahnManager">
<depends>jboss.jca:service=LocalTxDS,name=OracleDS</depends>
<depends>jboss.j2ee:service=EJB,jndiName=ejb/CurrencyBc</depends>
<depends>jboss.j2ee:service=EJB,jndiName=ejb/LoginBc</depends>
<depends>jboss.j2ee:service=EJB,jndiName=ejb/local/User</depends>
<depends>jboss.j2ee:service=EJB,jndiName=ejb/local/UserGroup</depends>
<depends>jboss.j2ee:service=EJB,jndiName=ejb/local/Command</depends>
<depends>jboss.j2ee:service=EJB,jndiName=ejb/local/SubCommand</depends>
</mbean>
</server>
Here's the bit of code I call in the MBean:
public void startService() {
log.info( "Starting Service" );
refreshSysConfig(); // Uses direct JDBC calls. Connection
looked up in JNDI.
refreshCurrencyManager(); // Uses direct JDBC calls. Connection looked
up in JNDI.
refreshIssuers(); // Uses direct JDBC calls. Connection looked up in
JNDI.
ensureTwoAdmins(); // The offending problem - uses Entity beans
}
public String ensureTwoAdmins() {
try {
log.info("Attempting to ensure two admins");
LoginBcHome home =
(LoginBcHome)RemoteHomeFactory.getFactory().lookUpHome( LoginBcHome.class,
JndiNames.JNDI_NAMES_LOGIN_BC_REMOTE );
LoginBcRemote loginBean = home.create();
Collection admins = loginBean.findUsersInGroup("admin"); //
Marked as txn required
if ( admins.size() < 2 ) {
loginBean.removeAllUsers();
createUser( "admin", "admin", "admin" );
createUser( "system", "system", "admin" );
return "Created admin/admin, system/system and god";
}
} catch (CreateException e) {
} catch (RemoteException e) {
} catch (TBException e) {
}
return "No new users created";
}
Finally, here's the exception stack trace.
