Helo, I get the following in my log (JRun 4, JDK 1.40.) :

Partial code of my Authentication class (but it worked once and stumbled on
AuthenticationForm instead... then I removed a duplicate struts.jar I
found).
package baepp;
import javax.servlet.http.*;
import java.util.*;
import javax.servlet.*;
import java.io.IOException;
import com.sun.java.util.collections.*;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionErrors;
...
public class Authentication extends org.apache.struts.action.Action {
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException, java.lang.NullPointerException {
...
javax.servlet.http.HttpSession session = null;
...
String userCompany = "";
String userLogin = "";
String userPassword = "";
String userLang = "";
...
int errorCode = 0;
...
java.util.Properties myProp = null;
baepp.Config myConfig = new baepp.Config();
java.util.Calendar logDate = java.util.Calendar.getInstance(new
java.util.Locale("en","US"));
session = request.getSession(true);
// former init method of servlet
...
...
if (!(session.isNew())) {
session.invalidate();
session = request.getSession(true);
}
...
// will set the locale (needed for form check) before getting the
language through the form
try{
ActionErrors errors = new ActionErrors();
userLogin = ((AuthenticationForm) form).getUserLogin();
userPassword = ((AuthenticationForm) form).getUserPassword();
userCompany = ((AuthenticationForm) form).getUserCompany();
userLang = request.getParameterValues("lang")[0];
// return the errors to the original form
if (!errors.empty()) {
return (mapping.findForward(mapping.getInput()));
}
}
catch(java.lang.NullPointerException e){
}
...
}
