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?
I noticed that the wsdl generated in the webbrowser (using my app URL?wsdl) is
not the same when using XFile ' wsdlGen ', and when using " wsgen " to
generate client's code, generated classes when using web-browser wsdl are not
the same when using the XFire generated one.
One more thing when generating wsdl with XFire tool I got at the end of the
file something like :
<wsdl:service name="LdapServiceService">
<wsdl:port binding="impl:ldapserviceSoapBinding" name="ldapservice">
<wsdlsoap:address
location="http://localhost:8080/ldap/services/ldapservice"/>
</wsdl:port>
</wsdl:service>
You can see that the service name is LdapServiceService and it is defined in my
services.xml LdapService, where this name comes from?
I attached to this message XFire generated wsdl file, and the one generated in
web browser, hope this will clarify my problem
Thank you in advance for your help

I didnt finde out your problem, I suggest to use different methode to invoke
yor service (Look http://xfire.codehaus.org/Client+API).
I hope that will help.

Hi..
Thank you for replying on my message.
I'm new to XFire, that's why I started with a small test : Java Swing GUI
to authenticate user, the authentification process is a webservice method
returning true.
Here's the code for the GUI ActionListener ( after removing all comments)
The following line is throwing the exception :
client1.invoke("login", new Object[]{username, password});
public void actionPerformed(ActionEvent e) {
try {
if(e.getSource() == loginBtn) {
if(usernameTxt.getText() != null && usernameTxt.getText().length() > 0 &&
passwordTxt.getPassword() != null && passwordTxt.getPassword().length >0){
String username =
usernameTxt.getText();
String password =
new String(passwordTxt.getPassword());
try{
Client client1 =
new Client(new URL( "http://localhost:8080/ldap/services/ldapservice?WSDL";
));
client1.invoke(
"login", new Object[]{username, password});
}
catch(Exception exp){
System.
out.println("exception "+exp);
}
}
else{
Boot.showError(
"Error", "Username and password cannot be blank", new Exception());
}
}
else if(e.getSource() == cancelBtn) {
usernameTxt.setText("");
passwordTxt.setText("");
}
}
catch(Exception ioExp) {
Boot.showError(
"Error", ioExp.getMessage(), ioExp);
}
}
and here is the Exception in Tomcat :

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:

client:
Client client1 =
new Client(new URL("

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
