RE: ServletException that I don't understand...

["G.Nagarajan" <gn...@dkf.de>]

Hi,
The error is in this line
 int lineNr = Integer.parseInt(nr);

It means that nr is not containing a valid integer.

to find out the value in nr, you can give something like

System.out.println("value of nr is : "+nr);
 int lineNr = Integer.parseInt(nr);

likewise you can give System.out statements wherever necessary and
find out where the value is not getting assigned properly.

Regards,
Nagarajan.

Subject: ServletException that I don't understand...


I'm getting the following exception when trying to load a jsp:

ServletException yadda yadda wrapping:

This seems to be an error in my jsp, and where the jasper Compiler is
parsing the line number from the javac output it's failing somehow...

<code>
       int beginColon = line.indexOf(':', 2);// Drive letter on Windows !!
       int endColon = line.indexOf(':', beginColon + 1);

       if (beginColon < 0 || endColon < 0) {
         errorMsg.append(line);
         errorMsg.append('\n');
         continue;
       }

       String nr = line.substring(beginColon + 1, endColon);
       int lineNr = Integer.parseInt(nr);
</code>

I'm not sure that the indexOf, beginColon construction is the stablest I've
seen...


Has anyone else run up against this? Any solution?


Jim
