rendering a page for an email: org.hibernate.HibernateException: createCriteria is not valid without active transaction

[Fernando Wermus <fe...@gmail.com>]

Hi all,
     I have coded the following to render a mail,


Application app;
try{
app=MyApplication.get();
}catch(Exception e){
app=new WicketTester().getApplication();
}
final Application app2=app;
final ExecutorService service = new ScheduledThreadPoolExecutor(1) {
@Override
protected void beforeExecute(final Thread t, final Runnable r) {
Application.set(app2);
};
@Override
protected void afterExecute(final Runnable r, final Throwable t) {
Application.unset();
}
};
service.submit(new ThreadMail(destinatarios, clazz, p));

But, I got a org.hibernate.HibernateException: createCriteria is not valid
without active transaction
when I tried to load an entity in a model to be used in the PageMail.

How can I attach the Transaction to the thread to get this working?

thanks in advance

This has nothing in particular to do with Wicket, and would be hard to
answer without knowing the details of what you are doing for transaction
management.
