Re: [jetty-users] Embedded jetty-all 8.1.x JNDI + Atomikos + OpenJPA 2.x
|
Thanks for the tip Jan! That seemed to get me further than I was...
I'm still running into an issue with the Transaction and I believe it's
related to the JNDI lookup. According to
http://wiki.eclipse.org/Jetty/Feature/JNDI#Configuring_XA_Transactions all
that is required is to add a new org.eclipse.jetty.plus.jndi.Transaction
passing in com.atomikos.icatch.jta.J2eeUserTransaction (which I found out is
for an older version of Atomikos; supposed to use
com.atomikos.icatch.jta.UserTransactionImp). It also states that we can then
lookup "java:comp/UserTransaction in your web app", but doesn't say how to
do this if we are just using a handler. Even so, if that is all that is
needed in a webapp, how does Jetty instantiate the
com.atomikos.icatch.jta.UserTransactionManager? I found that I had to add a
static call to com.atomikos.icatch.jta.UserTransactionManager.init() to my
Jetty configuration to get the transaction manager running. I then added a
org.eclipse.jetty.plus.jndi.Resource so it could be looked up by OpenJPA in
the persistence.xml (below). That all seems to work and I can get data back
from queries to the database, but I can't seem to get the
org.eclipse.jetty.plus.jndi.Transaction to be recognized. Is there another
step that I'm missing to get Jetty to expose the Transaction? Maybe a way to
get Jetty to instantiate the transaction manager instead of doing it myself
in the jetty configuration?

Will,
java:comp/env is a namespace related to webapps. You don't have a
webapp, just a handler.
Therefore, put your jndi bindings into the global namespace (rather
than the Server instance's namespace), and then look them up from that
global namespace.
So take out the <Ref id=Server> from the binding of your jndi
resource, then look it up with:
ctx = new javax.naming.InitialContext();
String configArg = (String) ctx.lookup("jdbc/myDS");
