Subject java xmlrpc client error
Date Thu, 27 Nov 2008 18:11:14 GMT
Hi,

I am trying to write a java xmlrpc client. However, I got the
"org.xml.sax.SAXParseException: Content is not allowed in prolog" error when
I tried to call "system.connect()" of my drupal site

After some searching, I found this:
http://www.openrdf.org/forum/mvnforum/viewthread?thread=86
"Java doesn't handle BOMs on UTF-8 files properly, making the three header
bytes appear as being part of the document. ..."

Is this the problem or something else?

Thanks!

Ethan

            Object result =  client.execute("system.connnect", params);
            System.out.println( result );


     }

A simple test with Python shows the site is configured correctly
import xmlrpclib
url = "http://speakingx.com/services/xmlrpc"
drupal = xmlrpclib.ServerProxy(url)
res = drupal.system.connect()
print res
