Hi,

I have an RCP client application based on eclipse 3.7.2. The application make calls to a websphere server using spring remoting invoker.
In this time I am facing a performance issue due to de-serialisation time of the objects results of the remote invocation,
With a java profiler I can see that the DefaultClassLoader open many times the same jar (attache a stack trace for more details) to load the same class.
I am looking for an option to cache loaded classes to optimize classes loading and then de-serialisation time, have you please any idea about that ?

Regards

Hi Marouen,

Is that related to Dirigible in any way? Probably, the particular forum or mailing list of the spring framework that you are using is better place for this question?

Hi Nedelcho,

Thank you for your reply

No no relation with Dirigibale.

I am not sure that the problem concerns eclipse, but my tests of the same service call with same parameters in my RCP application and in a Unit test shows a big difference between the de-serialisation time of the response Object in both sides.

I am trying to test a couple of eclipse OSGI options like osgi.framework.activeThreadType , osgi.bundlefile.limit for the moment with no impact.

In the same time I am looking for JVM (oracle 1.7) options that can optimize classloading.....

I will keep you informed if I will resolve the problem

Thanks
Marouen
