Hi...
I tried using Proxy but it doesn't help, I got the same error " Prefix cannot
be null when creating QName"
I thing I'm doing something wrong.
My webservice is deployed in Tomcat, and the client's classes generated from
the wsdl file are in the client application lib directory. is it ok like that?
here is the Exception in Tomcat :

When trying to invoke a method in my webservice, I'm getting the following
error:

client:
Client client1 = new Client(new URL("
http://localhost:8080/ldap/services/ldapservice?WSDL "));
client1.invoke("login", new Object[]{username, password});
It is a simple service to authenticate users.
java code:
package
com.imetrik.ims.webservice;
public
interface LdapService{
public boolean login(String username, String password);
}
the implementation :
public boolean login(String username, String password) {
boolean success = false;
if(username != null && username.length() > 0 && password != null &&
password.length() > 0){
if(username.equalsIgnoreCase("test") && password.equalsIgnoreCase("test"))
success = true;
System.out.println("inside login username = "+username +" password = " +
password );
}
return success;
}
my service.xml:
<beans
xmlns=" http://xfire.codehaus.org/config/1.0";>
<service>
<name>ldapservice</name>
<namespace>ldapservice</namespace>
<serviceClass>com.imetrik.ims.webservice.LdapService</serviceClass>
<implementationClass>com.imetrik.ims.webservice.LdapServiceImpl</implementationClass>
</service>
</beans>
Thank you in advance
