Are there any situations where your getAllData method can return null?

This is the code i used.Here i declared rslogin as null.

[HTML]<%
String id="",pwd="",area="";
int flag=0;
connectionMe();
java.sql.ResultSet rslogin=null;
if(request.getParameter("loginhidden")!=null)
{
if(request.getParameter("loginhidden").equals("log in"))
{
id=request.getParameter("txtId");
pwd=request.getParameter("txtPwd");
rslogin=getAllData("select * from login where username='"+id+"' and password='"+pwd+"'");
while(rslogin.next())
{
flag=1;
// session.setAttribute("UserId",id);
out.print("Login Successfully....");
// session.setAttribute("message","");
// redirect url
response.sendRedirect("process.jsp");
}
if(flag==0)
{
session.setAttribute("message","Invalid UserName or Password");
}
}

}

rs is still null at this point. You are calling static variables so use ResultSet (class name) instead of rs

.
That code throws a nullpointer only if the getAllData returns null. So you really need to be looking at your getAllData method.

I think that if your getAllData raises an exception inside the try-catch it returns null. May be that is the problem.

According to the line numbers supplied by the stack trace the NullPointerException
isn't raised anywhere in the piece of code you showed us; it is somewhere in
a method named 'myLogText' (or similar).

Tomcat also keeps a log for anything that is written to the standard out stream;
noticed anything peculiar in there?

kind regards,

Jos
