We've got some problems with an external company trying in integrate into a WCF service we expose and they are a Java shop. I was wondering if there are more than one toolkit that they can try to solve their issues and would like a list to suggest to them but I'm not familiar with the Java world at all.
Essentially they've got some memory leak (apparently!) but they are very sketchy in the details.
Are they using Axis, if you are presenting a standard webservice to them? Or are you presenting a custom REST service that they have had to do more manual coding for (HTTPClient, XML generators/parsers, etc)?
You need to ensure you're using a normal web service binding and nothing else. I admit though over the years getting java and .net web services to play nicely is no mean feat. A memory leak by the way, would have nothing to do with calling your web service and everything to do with the way the external company is managing their memory. You're not executing anything on their servers after all :-)
Microsoft and Sun worked together to ensure that their latest web services toolkits worked with each other. Sun's java implementation is Metro.
I've done this successfully with Axis. It was actually pretty straight forward, using the Eclipse plugins.
