Here is the spring code dont see any debug option here

try {
                // Try Hessian 3.x (with service interface argument).
                Constructor ctor = HessianSkeleton.class.getConstructor(new Class[] {Object.class, Class.class});
                checkService();
                checkServiceInterface();
                skeleton = (HessianSkeleton)
                        ctor.newInstance(new Object[] {getProxyForService(), getServiceInterface()});
            }
            catch (NoSuchMethodException ex) {
                // Fall back to Hessian 2.x (without service interface argument).
                Constructor ctor = HessianSkeleton.class.getConstructor(new Class[] {Object.class});
                skeleton = (HessianSkeleton) ctor.newInstance(new Object[] {getProxyForService()});
            }

Hi its 3.13, where do I put the debug property on the server or client ? Its exported via the hessian exporter in spring ill have to take a look at the api and see if it has that.

Hi ive only managed to call a method with one string param as an argument, trying ArrayLists of Objects String[] arrays of strings or objects gives me this

org.springframework.web.util.NestedServletException: Hessian skeleton invocation failed; nested exception is java.lang.UnsupportedOperationException: com.caucho.hessian.io.BasicDeserializer@1cea92:

Which version of Hessian is this with? There have been fixes in the most recent version (3.1.3).

Also, if you're using the 3.1.3 version, you may want to set debug="true" so we can look at the Hessian data.

When just simply sending strings as arguments i get this

com.caucho.hessian.io.HessianProtocolException: add: expected end of call ('z') at 'S'. Check method arguments and ensure method overloading is enabled if necessary

The C# code is like

List<ServerConfig> list = new List<ServerConfig>();
ServerConfig config = new ServerConfig();
config.name = "test";
list.add(config);
service.add(list);

on the java side

There is an interface and impl of

public void add(List<ServerConfig> config)
{

}

This is getting quite annoying because every kind of remoting impl ive tried that isnt soap doesnt work from C# to java and this was the easiest to setup in spring similar to rmi.

Let me know.
