Hi,

I'm trying to run a simple GWT project where I'm trying to do a simple persitence via hibernate to a HSQLDB database. The database I'm using I have been using for at least 2 years with several osgi applications without any problems. So all I done is reused the same configuration and added a simple object mapping file. The problem I have is that I get a socket creation error when ever I try to persist the object with in GWT jetty. I now the database is up and running, I can telnet to it, run OSGI projects that uses the same config with out problems. This is the stack I get when running
