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:
SEVERE: Error: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
