[xfire-user] prefix cannot be "null" when creating a QName

[Youssef Moussa]

Hi..

Please help to resolve this error. I'm missing something but what I don't know. 
I'm using xfire 1.4, tomcat 5


When trying to invoke a method in my webservice, I'm getting the following 
error:
SEVERE: Error:prefix cannot be "null" when creating a QName

org.codehaus.xfire.fault.XFireFault: prefix cannot be "null" when creating a 
QName

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) {

// TODO Auto-generated method stub

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
