Hi,

I'm using GroovyWS to integrate a third party WSDL into my Grails project,
and my Grails project has to be able to service multiple requests at the
same time. So this is what I have:

- User facing gui sends a HTTP request to a Grails Controller
- Controller calls a Grails Service
- Grails Service creates a new WSClient using the 3rd party WSDL for the
request, then makes calls to the 3rd party webservice, then returns the
results to the user facing gui as XML

If I do one request at a time, everything works fine. However, if I do
multiple requests at the same time, it looks like my code breaks when
creating a new WSClient.

Is this because I'm creating multiple WSClients (one for each request) at
the same time? Below are the details of the error I get.

Thanks,
Bilal
