Comment on CDI and Transactions e.g. in JBoss-7.0.2 by jonny

@Daniel: Uh, you are right my little example snippet is not feature complete. I would advice to throw an appropriate exception in that case… What do you think?

@Sven: Indirection “as it is” is a nice thing, but in a container environment like an application server you get it all “for free”, i.e., you don’t want all of it, but hey it’s there…

CDI on the other hand gives you the control to add indirection and therefor container facilities step by step. If you think: “enough is enough” you may stop adding more indirection. But all that glistens is not gold.

Nice post!

BTW: that is going to be a bitch if transaction is in state STATUS_MARKED_ROLLBACK or other states in which you cannot start a new transaction:

if (tx.getStatus() != Status.STATUS_ACTIVE) {
utx.begin();
}

Interesting post! Despite all the involved indirection, I like the elegance of CDI.

Comment on Standalone Tomcat with jBoss plus authentication against LDAP by jonny

There is no propagation. The Login name and credential is stored in a static class member (of the login module) and later reused for a login during creation of the InitialContext initializing the connection to the JNDI of the jboss.

Hi Jonny
I realy didn’t undertands how standalone web container propagates JAAS autentication to ejb container !!!! I’ve read a lot of stuff and I realized that I must config and duplicate roles inside war and ejb xmls….and duplicate the specific way how this container will autenticate and authorized (XML, JDBC, LDAP etc….)
I’m right ??
Best Regards

I don’t have a solution for a productive system by now. But I’m working out a solution using REST-services to access a jboss from an external tomcat. I will write a concept post soon.
