How to disable DTD validation, supress downloading dtd from w3.org

2009-12-10T01:06:36Z

Hi there,

Since a few weeks we get the following exception when we fetch informations
from the Trac-System via xml rpc.
Is it possible to disable the xml validation - or to supress the dtd
download from w3.org?

Thanks!

types problems version 3.1.2

2009-12-03T04:13:01Z

Whit this new library's there is a lot of problem using HashTabele as one of the input parameters in client execution.

With old library's everything work fine, why is know such problem using different types of data.

I try to do this:
String username;
Map keyVals;
String sessId;

Object[] params = new Object[]{username, keyVals, sessId};
rez = client.execute("Calculus.DoInter", params);

available data types

2009-12-03T03:25:21Z

On page are list of valid types http://ws.apache.org/xmlrpc/types.html , but for java.util.Map it doesn't say if raw type or parametrized(Generic).

Regards, Tomaz

org.apache.xmlrpc.XmlRpcException: type error

2009-12-03T02:45:27Z

Is there any way to get more debug level in xml-rpc, I get this error:

org.apache.xmlrpc.XmlRpcException: type error

which is hard to figure it out what is wrong.

Regards, Tomaz

xml-rpc over SSL; strange behavior

2009-12-01T04:24:43Z

Is it possible a client close connection, client use SSL.
I have very strange problem with all apache xml-rpc (1.2 or 3.1.2 version) library when using SSL.

I have this: xml-rpc client in java (using 1.2. version OR 3.1.2 version) xml-rpc server(c++)

1) When I use client(whith SSL) on centos, ubuntu it works fine, but if I use it on Win XP it crash server.

XP OS(java 1.5 or 1.6): Actually first run a client program It looks everything fine, but second run of client, crash server.
Linux OS(java 1.5 or 1.6): Client run for many times and server is still alive.

It seam that something is wrong with SSL communication, I can't figure it out.

2) Is it possible from XmlRpcClient close connection(SSL)?

3) What is the best pratice to use XmlRpcClient with SSL?

4) XmlRpcClient version 1.2 I use this class org.apache.xmlrpc.secure.SecureXmlRpcClient and set the keystore and truststore

Can I close SSLContext through SecureXmlRpcClient ?

5) XmlRpcClient version 3.1.2 I use SSLContext and HttpsURLConnection which I set him default socket factory

HttpsURLConnection.setDefaultSSLSocketFactory(sslc.getSocketFactory());

Is there any better way to use SSL communication?
How to send close connection from client?

Any ideas,

regards Tomaz

INFO ABOUT XML RPC METHOD CALL

2009-11-20T09:38:46Z

Hi,
I've a question about the newXmlRpcHandlerMapping() method on XmlRpcServlet.

I've a test class as this:

@Override
protected XmlRpcHandlerMapping newXmlRpcHandlerMapping()
throws XmlRpcException {
PropertyHandlerMapping mapping;
URL url = XmlServlet.class.getResource("XmlRpcServlet.properties");
if (url == null) {
throw new XmlRpcException(
"Failed to locate resource XmlRpcServlet.properties");
}
try {
mapping = newPropertyHandlerMapping(url);
} catch (IOException e) {
throw new XmlRpcException("Failed to load resource " + url + ": "
+ e.getMessage(), e);
}

AbstractReflectiveHandlerMapping.AuthenticationHandler handler = new
AbstractReflectiveHandlerMapping.AuthenticationHandler() {
public boolean isAuthorized(XmlRpcRequest pRequest) {
XmlRpcHttpRequestConfig config = (XmlRpcHttpRequestConfig) pRequest
.getConfig();
return isAuthenticated(config.getBasicUserName(), config
.getBasicPassword());
}
};
mapping.setAuthenticationHandler(handler);
return mapping;
}

and in my XmlRpcServlet.properties I've the mapping of the class
(MethodExample.java) that exports public methods. But how I can get
username and password in my MethodExample.java since is a POJO?

Thanks very much.

Best regards

many requests are sent before getting the errors. and continues till the last request. although it gets the error, the client continues to get the result for all the requests that were successfully send.

It still seems to have some connection breakdown after certain number of requests. This is really bugging me! Can you confirm if it is the problem?

as for your suggestion to use fully blown servlet, i would like first to get this WebServer working before submerging into servlet engine.

thanks again!

Might be the problem in the connection pool that was resolved some
time ago. Please try to build from the latest sources and use that
version.

If that doesn't help, consider using a fully blown servlet engine like
Tomcat or Jetty and not a toy like the WebServer class.

But when i have higher requests more than 250, the xml rpc client gets the error. the error is 'connection refused' caused by java.net.connectionexception.. it seems to me that somehow WebServer limits the number of concurrent requests and doesn't accept any more connections. anyway, I would be happy if you guys could give some hint or let me know if you had also similar situations.

xmlrpc client crashes with high concurrent requests

2009-11-05T07:01:04Z

Hi,

I have made a xmlrpc client-server architecture which uses the minimal HTTP server 'WebServer class'.
Currently i am doing some load test on my server architecture. And of course, I am getting some error.
With single request or concurrent requests less than 250 or 300 (sometimes 200) works fine and i get the result. But when i have higher requests more than 250, the xml rpc client gets the error. the error is 'connection refused' caused by java.net.connectionexception.. it seems to me that somehow WebServer limits the number of concurrent requests and doesn't accept any more connections. anyway, I would be happy if you guys could give some hint or let me know if you had also similar situations.

thanks

getServletContext() from my class that processes xmlrpc

2009-11-03T13:53:11Z

I'm trying to call getServletContext from a class that the XmlRpcServlet is
using for processing requests.

I'm using spring's IOC, and I need to get the context to get the bean
factory.

Thanks,
Mike.

I kind of thought that, since the access log does not even show that I'm connecting.

I don't really trust this. I'd expect that you have some problem in
your setup, like not properly reloading, or something like that.

Anyways, as the problem is way before the XML-RPC code is touched, I
suggest that you contact tomcat-user, or a similar mailing list for
your web server.

I tried both, removing the /* and leaving the test script gives a 302 error, leaving the /* and adding / to the test script gives 404.

Any other ideas?

Alternatively, remove the /* from the pattern below.

Try using the URL from the location header. In other words, add a "/"
to the URL.

Daphna, we don't have access to that information. All we have is the exception you are seeing. We ask the SSL library for an incoming connection, or get a connection from Tomcat (or whatever servlet engine might be in use). If we get it, fine, if we don't get it, there's an exception.

Hi Daphna,

I know it is a long shot but the the Charles Web Proxy
(http://www.charlesproxy.com/) supports SSL proxying (see
http://www.charlesproxy.com/documentation/using-charles/ssl-proxying/)

Cheers,

Siegfried Goeschl

Problem (302 moved error)

2009-10-28T12:48:50Z

I have the following java class:

package com.secmgmt.xmlrpc.change_status;
import org.apache.log4j.Logger;

public class ChangeStatus
{
public static final int SUCCESS = 0;
public static final int INVALID_LOGIN = 1;
public static final int EID_NOT_FOUND = 2;
public static final int SERVER_NOT_PRIMARY = 3;
public static final int NO_CHANGE_NEEDED = 4;

private static Logger l = Logger.getLogger(ChangeStatus.class);

public static final String ACTIVE = "ACTIVE";
public static final String INACTIVE = "INACTIVE";

public static final int PP_ACTIVE = 0;
public static final int PP_INACTIVE = 1;

public ChangeStatus()
{
l.debug("Created the status xmlrpc class");
}

public boolean ping()
{
return true;
}

public int add(int one, int two)
{
l.debug("Adding " + one + " and " + two);
return one + two;
}

public int changeStatus(String eid, String user, String password, String
status)
{
return SUCCESS;
}
}

The following in the properties file:
ChangeStatus=com.secmgmt.xmlrpc.picture.four.change_status.ChangeStatus

My webapp deploys properly, and I never see an error in the logs anywhere
when I hit it. My python program is:

#!/usr/bin/python2
import xmlrpclib
from pprint import pprint

p = xmlrpclib.ServerProxy("http://192.168.1.15:8080/xmlrpc-status")
print "Server created"
try:
#print p.system.listMethods()
#print dir(p)
p._ServerProxy__verbose = 1
print "Ping result: %s" % (p.ChangeStatus.ping())
except xmlrpclib.Error, v:
print "ERROR", v
pass

print "Done"

Here is the output:

Server created
connect: (192.168.1.15, 8080)
send: 'POST /xmlrpc-status HTTP/1.0\r\nHost:
192.168.1.15:8080\r\nUser-Agent: xmlrpclib.py/1.0.1 (by

send: "<?xml

reply: 'HTTP/1.1 302 Moved Temporarily\r\n'
header: Server: Apache-Coyote/1.1

header: Connection: close
ERROR <ProtocolError for 192.168.1.15:8080/xmlrpc-status: 302 Moved

Done

Any idea why I get the 302 error? My XML-RPC appears to be correct.

I understand its an SSL related problem, however I need information on the specific client which sent the bad message (there are dozens XML-RPC requests per minute). There is nothing in the XmlRpcErrorLogger which helps to identify that problematic client request. Can such information be added to the exception ?

is it possible to check the traffic using Wireshark or an HTTP proxy?

Vague XML-RPC exceptions

2009-10-26T10:43:26Z

Hi,

We are using XML-RPC version 3.1.1 with SSL in our application.

We have been receiving the following XMLRpc exceptions, and are unable
to figure them out, as we cannot determine which request caused it or by
whom it was sent (dozens of XML-RPC requests are sent in 1 min).

Adding tag in XML-RPC 3.1

2009-10-19T06:33:56Z

Hi,

We are using java XML-RPC library 3.1; when my client application send's string datatype, <string> tag is missing.

String tag missing::

<?xml version="1.0"\?>
<methodCall>
<methodName>GetMyDetails</methodName>
<params><param>
<value>
<struct>
<member><name>originNodeType</name><value>EXT</value></member>
<member><name>originHostName</name><value>testserver</value></member>
</struct>
</value>
</param>
</params>
</methodCall>

Expected request message with string tag::

<?xml version="1.0"\?>
<methodCall>
<methodName>GetMyDetails</methodName>
<params><param>
<value>
<struct>
<member><name>originNodeType</name><value><string>EXT</string></value></member>
<member><name>originHostName</name><value><string>testserver></string></value></member>

RE: XML RPC Question

2009-10-13T21:27:43Z

Hi Jochen,

The setup is running in production for more than 1 year and we are
seeing the timeout behaviour only recently when the time of execution of
the server process is >1hr.Modifying the arch would be quite difficult
at this point.

I was looking at multiple layers and was little sceptic on if there
could be an inbuilt timeout that would be available.Please let me know
if that could be possible or is there no such param availbale?

Thanks for your help.

Regards,
Bala

Hi,

if your task actually requires more than one hour to run, I'd strongly
recommend an asynchronous procedure, like this:

- On the server, spawn a thread, which creates a unique ID. The new
thread
starts performing the task and returns the ID to the client.
- Client starts running in a loop. Every minute or so, send a query to
the server,
whether the thread is ready. If so, leave the loop. Otherwise, go
sleeping for
another minute.

Should be much easier to implement than taking care of all these TCP/IP
and HTTP related timeout considerations.

Re: class cast exception with array return result

Hi,

you are right, there is a bug in FAQ.
the point is, that you can not cast the result of the XML RPC call, in your
case

return (String []) windows.getInstances(category);

is the problem.
You have to transform the result to String[] as described in the FAQ (but
without the cast in the first line of FAQ example)

If you have any further questions, pls, ask ;-)

Re: XML RPC Question

2009-10-13T12:23:20Z

I agree, your communications would then be much more resistant to
network interruptions. And if the server and client each store the
unique ID (along with essential parameters), either could possibly be
shutdown and restarted and be able to resume the transaction.

class cast exception with array return result

2009-10-13T10:06:15Z

I am continuing this from my bug post (sorry).
I am having difficulty with an array not being cast properly. I have done what is outlined on here as far as I can tell.
http://ws.apache.org/xmlrpc/faq.html#arrays

This is the issue I opened for some background info
https://issues.apache.org/jira/browse/XMLRPC-178

I have done what is in the last comment, and I am still getting the class cast exception, I am really unsure where to go from here and any help would be much appreciated.

starts performing the task and returns the ID to the client.
- Client starts running in a loop. Every minute or so, send a query to
the server,
whether the thread is ready. If so, leave the loop. Otherwise, go sleeping for
another minute.

Should be much easier to implement than taking care of all these TCP/IP and
HTTP related timeout considerations.

XML RPC Question

2009-10-13T06:49:54Z

Hi,

We are making use of a configuration where the XMLRPC Server is brought
up in one linux server and the XMLRpc Client class is invoked in another
Linux Server(via a shell script and both are behind the firewall).The
XMLRPC server invokes a java business class and it runs for more than
one hour.The server is set to return "0" on success and "1" on failure.

We are seeing the connection to be terminated b/w the client and server
exactly after one hour although the server process is completing without
any issues.We are seeing a "Connection reset" error and the message
displayed is an error (msg to be displayed when return is 1).However,we
are not seeing any exceptions in the server log(after 1 hr and 30 mins
run).We are seeing success messages or completion of the business class.

Is there a default connection timeout that is set/could be defined b/w
the XMLRPC Client and Server?Or could it be a socket connection
timeout/OS level timeout that could be creating the issue?

Regards,
Bala
