problem with Persistence.createEntityManagerFactory

[Jordan Thompson]

Hi all,
I have an application that runs fine as an application. I have (tried) to package it as a web start app, but it dies at Persistence.createEntityManagerFactory(). When I say dies, I mean nothing happens - it never returns from the call. I have not been able to debug it as a web application - I have set up a logger that prints to a file and the last thing in the file is "INFO Getting an EntityManagerFactory"

Here is part of the code:

        myLogger.log(Level.INFO, "Getting an EntityManagerFactory");
        EntityManagerFactory entityManagerFactory =
                             Persistence.createEntityManagerFactory(myPersistenceUnit,
                new HashMap<String, String>() {
                    private static final long serialVersionUID = 1L;
                    {
                        put("hibernate.show_sql", "false");
                        put("hibernate.connection.url", myUrl);
                        put("hibernate.connection.username", myUsername);
                        put("hibernate.connection.password", myPassword);
                    }
                });
        myLogger.log(Level.INFO, "Setting myEntityManager");

This code is never called:

        myLogger.log(Level.INFO, "Setting myEntityManager");

Here is my jnlp file (all three jar files listed are signed - there are others in the lib directory that are not):

<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0"
 codebase="file:."

     <update check="background"/>
</jnlp>					

Here is the list of files in my lib directory:

mysql-connector-java-3.0.17-ga-bin.jar
thompco.jar


I am really at a loss - I have tried running from the command line in hopes that something may be printed, but am disappointed that nothing shows up.
I have tried to debug from netbeans, but cannot connect to the port (8989) I specified (any suggestions here would be very helpful.)
set JAVAWS_TRACE_NATIVE=1
set JAVAWS_TRACE_NATIVE=1
set JAVAWS_VM_ARGS=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjwp:transport=dt_socket, address=8989,server=y,suspend=n
javaws dataApp.jnlp

thanks for any help you may have for me.

this has been resolved - turns out that I had removed the mysql jar and added back the mysql library. Ant did not include the library (but it did include the jar.)
