Remote services and Hessian

[gpoirier]

Actually, the non-java client thing is a non-issue, because the server always support both mangled and non-mangled method names, it's the client that default not to mangle method name. However, not mangling method name is the default value of hessian/burlap, Spring just doesn't mess with that if not asked. I guess caucho decided to have non-mangled method names by default for performance reasons.

Hello,

I have exposed a Hessian service in my web-app and am trying to connect a standalone client to it. I seem to be getting the error:

com.caucho.hessian.io.HessianProtocolException:
at com.caucho.hessian.client.HessianProxy.invoke(Hess ianProxy.java:176)
at $Proxy0.createArrayDesign2Persist(Unknown Source)

.....

my client config file is:

<beans>
<!-- Remoting -->
<!-- Server Side RMI is on port 1299 ... see IntegrativeMetaAnalysis
springapp-servlet.xml -->
<!--Client Side Hessian -->
<bean id="readFile" class="tools.SimpleClientObject">

Any ideas? The only difference between this and the Spring examples I have looked at is the fact that I am using a standalone command line client as opposed to another servlet.

Any help would be greatly appreciated.

Thanks.
