Re: [Wicket-user] Hibernate transactions

[Igor Vaynberg]

There is in fact an on error handler Application.onRuntimeException(). its called whenever there is a runtime exception. instead of trying to do try/catch in your filter you can use a request variable to indicate success/failure. set it to success, and in the error handler set it to failure. I use this approach whenever i know my requirements will never exceed the single-transaction-per-request limitation.

Hope this helps,

Hi,

I am using hibernate with my wicket application and was wondering how I can
control transactions?  Usually I use a servlet filter that either commits the
current transaction or rolls it back.

Something like this:

try
{
   chain.doFilter(req, resp);
  // commit if needed
}
catch (Exception e)
{
  // roll back if needed
}
finally
{
  // close session if needed
}

I am using wicket HEAD and all exceptions are caught and handled in the
RequestCycle so my catch block is never called.  Instead of using a servlet
filter I tried subclassing WebRequestCycle to use onBeginRequest and
onEndRequest.  But how do I catch exceptions to rollback the current
transaction?  I was looking for some kind of onError handler.

How do others handle this?

Thanks,

John
