Hi all,

I have an application which uses hibernate that runs fine in hosted
mode, but no longer when deployed.
Here's the details:

In hosted mode it connects to a database that resides on a remote
server.
Connection details set in hibernate.cfg.xml

When run I it get a long stacktrace with errors similar to the
following:

SEVERE: Unable to instrument
com.google.gwt.user.server.rpc.impl.ServerSerializationStreamWriter
$ValueWriter$8. Security restrictions may not be entirely emulated.

Which apparently has to do with the fact that it's being run in hosted
mode, and I read that it can be ignored.
The application saves and retrieves data without problems.

After deploying it on appspot and when I try to save a new row in a
table I get this:

javax.servlet.ServletContext log: Exception while dispatching incoming
RPC call
com.google.gwt.user.server.rpc.UnexpectedException: Service method
'public abstract boolean

com.appspot.positivevoice.client.panels.blog.BlogService.saveBlog(com.appspot.positivevoice.client.models.BlogModel)'
threw an unexpected exception: java.lang.NoClassDefFoundError: Could
not initialize class com.mysql.jdbc.ConnectionImpl
at
com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java:
378)
at
com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:
581)

Since the app works fine in hosted mode ( apart from those
exceptions ) I am not even sure which files I should add to the
post...

Any idea much appreciated!

Thanks
