Hi Jochen,
I have been experimenting with these two classes inside Jetty, but now I
seem to be a bit stuck. Let me show some code:
---------------------------------------------------------------------
// First initialize the server
XmlRpcServerConfigImpl serverConfig = new XmlRpcServerConfigImpl();
serverConfig.setEnabledForExtensions(true);
serverConfig.setKeepAliveEnabled(true);
PropertyHandlerMapping dhm = new PropertyHandlerMapping();
try {
dhm.addHandler("Ums", MethodForwarder.class);
} catch (XmlRpcException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
XmlRpcLocalStreamServer server = new XmlRpcLocalStreamServer();
server.setConfig(serverConfig);
server.setHandlerMapping(dhm);
---------------------------------------------------------------------
I guess so far so good. Now initialize the client with the inputstream I
get from Jetty:
---------------------------------------------------------------------
// initialize client
XmlRpcClientConfigImpl clientConfig = new XmlRpcClientConfigImpl();
clientConfig.setEnabledForExtensions(true);
clientConfig.setContentLengthOptional(true);
LocalStreamConnection lsc = new LocalStreamConnection(clientConfig, new
LimitedInputStream(getInputStream(), getInputStream().available()));
---------------------------------------------------------------------
Now I want to execute the client request at the server:
---------------------------------------------------------------------
try {
server.execute(clientConfig, lsc.getServerStreamConnection());
} catch (XmlRpcException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Answer: "+lsc.getResponse().toString());
---------------------------------------------------------------------
When I execute this I get an exception:
java.lang.NullPointerException

After looking a bit in the code I found that this nullpointer was thrown
because the
setXmlRpcServer(XmlRpcRequestProcessor pServer)
property was not set in the XmlRpcClientConfigImpl object. So I added
the following line to the client config:
clientConfig.setXmlRpcServer(server);
setting the server as the xmlrpcserver of the client. However, when I
added this line I got a non stopping throwing of the following
exception:
java.lang.StackOverflowError

org.apache.xmlrpc.server.XmlRpcLocalStreamServer.execute(XmlRpcLocalStre
amServer.java:14)
org.apache.xmlrpc.server.XmlRpcLocalStreamServer.execute(XmlRpcLocalStre
amServer.java:14)
org.apache.xmlrpc.server.XmlRpcLocalStreamServer.execute(XmlRpcLocalStre
amServer.java:14)
....
It appears like a loop which constantly throws this error.
Any ideas of what I am doing wrong?
Regards
p.

Take the XmlRpcLocalStreamServer and the LocalStreamConnection as an
example: A raw InputStream is fine. (That's what the XmlRpcStreamServer
is made for.)
