Spring RPC with hessian over HTTP works fine on maven tomcat plugin, but return http 500 error on Tomcat server

I work with Spring RPC with hessian over HTTP, it works fine when I tried it on maven tomcat-plugin(Servlet Engine: Apache Tomcat/6.0.29, Java 7).

But after I packaged it with maven-war plugin and deployed on a tomcat server.(I have tried both 6.0.36 and 7.0.37), the RPC call returns 500 error.

I'm not sure what's the difference between these two usage of tomcat. RPC call is from same procedure to it's HTTP service, I mean they use same code. Two parameters are both String.

I have tried to add a MIME-TYPE as "application/x-hessian" to tomcat server, 500 is still there.

Anyone knows what's wrong with my tomcat server?

update question:

Thank you @Ralf, you are right, the old log didn't show the server error, I added new logs.

The server side log shows error about HessianProtocolException, and I found a method to resolve this: down grade the hessian version to 3.1.5, now the RPC works.

But, the question is still there, why when I use 4.0.33, the tomcat started by maven plugin works fine, the stand alone tomcat shows error?

My interface is

public interface RemoteMessage {
    public boolean callMethod(String number, String content);
}

Remove spring-remoting dependency. It conflicts with latest version of hessian library. I faced the same problem & after googling I found this HessianConnectionException: (HTTP) 500 error when using Hessian 4.0.7 & Spring 3.1.1 .
