Hello Ruwan,
I have a small test case to reproduce the second issue (unknown character).
Maybe this problem also applies to issue one.
As you expected the issue seem to be related to the response size.
Please consider the following basic service code which is based on your Hessian
sample.
BasicAPI.java:
--------------
package com.sample.server;
import java.util.List;
public interface BasicAPI {
public List getResultObjectList(int listSize);
}
ResultObject:
-------------
package com.sample.domain;
import java.io.Serializable;
public class ResultObject implements Serializable {
private Long id;
private String s = "äüö&?ß_\\/241234";
public ResultObject(Long id) {
this.id = id;
}
public String toString() {
StringBuffer sb = new StringBuffer(64);
return sb.append("id = ").append(id.toString()).append(", s =
").append(s).toString();
}
}
HelloServlet:
-------------
package com.sample.server;
import java.util.ArrayList;
import java.util.List;
import com.caucho.hessian.server.HessianServlet;
import com.sample.domain.ResultObject;
public class HelloServlet extends HessianServlet implements BasicAPI {
public List getResultObjectList(int listSize) {
List list = new ArrayList();
for (int i = 0; i < listSize; i++) {
ResultObject o = new ResultObject(new Long(i));
list.add(o);
}
return list;
}
}
In the client code you can test with diffent values for the listSize parameter.
I tested 5, 10, 20, 50, 100 successfully. As I changed the parameter to 500 I
got the following exception:
Caused by: com.caucho.hessian.io.HessianProtocolException: unknown code:?

By the way, where do I find the source for your Hessian additions? I had a
short look at the Axis2 repo but could find the classes.
So I took a quick look in the Axis2-hessian.jar.
Could you please have a look at MessageFormater.getBytes()! I saw a suspicious
limitation to 8192 bytes while reading from an inputstream.
I hope some of the information is helpful to track down the problem.
Regards,
Eric
