JWS & JasperReport, fail to open JPrint with JasperViewer

Question

Hi,
I'm developping an application that use JWS and JasperReport. It's a client-server application. The server create the report and save it as JPrint, transfer it to the client and the client open it with JasperViewer. It runs well in local without using JWS, but when JWS is used, the client can't open the jprint with the JasperViewer. Nothing appends, no exception is thrown and the thread of that process is cut off (just stop working). I think it might be a memory lack or something, but I have no evidence of that. Someone know something about it?
Thanks !!

i alrealy checked the logs and nothing apear. It may be useful to see this :
System.out.println("Pass 2");
JasperPrint jp = JRPrintXmlLoader.load(response.getAttachment());
System.out.println("Pass 3");Don't ever do this. It's a waste of your time. Use a debugger so you can step in and out of code and see what's going on. Using System.out isn't going to tell you much, as you've just seen.
The first line is executed, but not the third and no exception is thrown( If it was the case, it is in a try/catch block with printStackTrace)
For the profiler, maybe you can show me where I can learn how to use this ?Google for OptimizeIt or JProfiler. NetBeans comes with a free one I hear but I've never used it since I find NetBeans impossible to use for basic needs, much less something as advanced as profiling.
