XML JDOM XPATH NumberFormatException

Hi Experts..:)

My head is about to explode..:eek: The attached little piece of code has been working succesfully, but suddently it results in a NumberFormatException:

java.lang.NumberFormatException: For input string: ""
java.lang.NumberFormatException.forInputString(Unk nown Source)
java.lang.Integer.parseInt(Unknown Source)
java.lang.Integer.parseInt(Unknown Source)
Entry.doGet(Entry.java:43)
javax.servlet.http.HttpServlet.service(HttpServlet .java:617)
javax.servlet.http.HttpServlet.service(HttpServlet .java:717)

I really hope some one can give me a clue, how to solve the problem..:(

So the error is on line 43 of the Entry class, this line:

Code:

---

p = Integer.parseInt((String)port.get(i));

---

and instead of a number, you're getting an empty String "". I'd use either a debugger or a bunch of println(...) methods to find out the state of your program when the error occurs. You should be able to tell which line of the XML is tripping the error.

You are absolutely right - there was a mistake in the XML-file which i corrected now.. Thank you.. You have been a great help..:)

Cool. Glad it helped.
