Create CXF dynamic client invoking WSDL
Hi all
When I try creating a web service client using CXF's dynamic client api to
invoke a wsdl on server side (see the following), an exception was thrown
complaining the operation already exists. All what I'm trying to do here is
simply creating a client, why could this exception be triggered?
*Code:*
import java.net.URL;
import java.net.URLClassLoader;
import javax.xml.namespace.QName;
import org.apache.cxf.endpoint.dynamic.*;
import org.apache.cxf.endpoint.Client;
public class DynamicClient
{
public static void main(String[] args)
{
try
{
DynamicClientFactory dcf = DynamicClientFactory.newInstance();
Client client = dcf.createClient("*http://servicehost?wsdl*");
}
catch (Exception e)
{...}
}
}
*Output
*log4j:WARN Continuable parsing error 2 and column 69
log4j:WARN Document root element "log4j:configuration", must match DOCTYPE
root "null".
log4j:WARN Continuable parsing error 2 and column 69
log4j:WARN Document is invalid: no grammar found.
log4j:WARN No appenders could be found for logger
(org.apache.cxf.bus.spring.BusApplicationContext).
log4j:WARN Please initialize the log4j system properly.

Re: Create CXF dynamic client invoking WSDL
Posted by Benson Margulies <bi...@gmail.com>.
Roughly, it means that the code generator that runs for the dynamic client
tried to make the same operation twice, since it thought that the WSDL asked
it to.
Can you post the wsdl?
