Can I intercept calls for my WSDL on Glassfish (or on any application server)?

Question

I created the Java web service using annotation @WebServiceand deployed the service to the Glassfish server, which lives behind the proxy server.

The problem is that someone accesses our WSDL and looks at the location of the service endpoint address that they see

http://app server url/service...

instead

http://proxy server url/service...

I would like the proxy server URL to be returned to the address point of the WSDL service endpoint instead of the application server URL.

I am wondering if I can write a filter or listener to listen for WSDL requests and then change the address of the WSDL service endpoint with the proxy server URL? What could be the recommended way to do this - I thought the filter was the best choice, but was not 100% sure?

If Apache is your proxy server, you can try to do what I did, which is very simple. Apache is causing the problem (sorting), so use Apache to fix it:
