GileadRPCServiceExporter

[Huage Chen]

Hi all,
I'm trying to migrate from Hibernate4Gwt to Gilead, however I have the following problem: when I call a rpc service, I receive the following erreur.

2008-11-28 16:48:28,445 org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/Gali] log line 676 Exception while dispatching incoming RPC call

It seems to be a service mapping problem, I have the following servlet mapping file, and I have well defined Hibernate BeanManager in another file:

Can anyone tell me what's wrong with my configuration? Thanks a lot.

Hi

Looks like a version error between GWT-SL and GileadRPCExporter. Which version of GWT-SL are you using ?

Hi Bruno,

I have imported the java file into my project, and it works now, but I have a serious problem concerning the performance. By the way, I have sent you a mail to explain the problem. I don't know if it is a general problem for Gilead, if so, I will post it in this forum later.

Thanks a lot for your help.

Regards

Huage
