Sebastian Wiemer commented on XMLRPC-137:
-----------------------------------------
I did a quick fix on this using the following patch:
-- XmlRpcStreamServer.java
183,184c183,186
< istream.close();
< istream = null;
---
> // changed my -snwiem-
> // This will throw an IOException (stream
> already closed) on Sun AppServer 7 !!
> //istream.close();
> //istream = null;
192a195
> istream = null;
211,212c214,215
< ostream.close();
< ostream = null;
---
> //ostream.close();
> //ostream = null;
214a218
> ostream = null;
220,221c224,225
< dest.close();
< dest = null;
---
> //dest.close();
> //dest = null;
223a228
> dest = null;
Cause: I don't see the requirements to explicitely close the streams in the
public void execute(XmlRpcStreamRequestConfig pConfig, ServerStreamConnection
pConnection) method. All stream-handling is done within the finally-blocks
anyways, catching all errors away ;)

> Hi,
> there's an issue with the Sun Application Server 7 on booth ends (client,
> server) using XmlRpcServletServer. This error does not occure on Tomcat 5x
> (running booth client and server) or other client/server implementations
> based on eg python or ruby.
> The clients successfully send the request to the server endpoint. The server
> recieved to call and processed all parameters. The error seems
> to occure, when the server writes the response back to the client. The
> problem is, that althouch the business logic behind the request was processed
> correctly, the client doen't have a chance to get the response value
> (including exceptions)
> On the server side we get the following exception:
