valley1girl · #1 29-Dec-2006, 12:50

Hi I was wondering if anyone could see why i'm getting the Error

Code:

Exception in thread "main" java.lang.NullPointerException
	at java.awt.Container.addImpl(Unknown Source)
	at java.awt.Container.add(Unknown Source)

Like, oh my god!, let's like totally do a stack trace of that 'Exception'...

(from the bottom->up)
line 37 is this statement, in main():

JAVA Code:

     Interface gui = new Interface();

Well that looks ok, nothing strange, just creating a new Interface object, so move to the next line (up the stack)...

line 56 is this statement [note the <init> implies "during construction" (or "in the constructor")]

JAVA Code:

     this.setContentPane(getJContentPane());

this still looks ok, but there is a function call as the argument, could that be causing trouble? Lets follow the stack (up another line)...

to line 99:

JAVA Code:

     jContentPane.add(jToolBar,BorderLayout.NORTH);

Whoa!, looky here, we are IN that function call [from line 56], and there is something about this statement causing the add() call to bomb (the 'null pointer' exception), because the last two dump lines have 'unknown source'.

So, what is it about this statement [line 99] that could possibly be null?

I'll stop here to let you ponder it, but if you get stuck, post another reply.

Hi thanks for your help but I still don't understand how it is null. I'm kinda new to java and debugging so if im appearing naiive, sorry, but is there anything else that you can tell me as a hint.

thanks again,
Kirsty

TurboPT · #4 30-Dec-2006, 21:14

Another hint: follow your constructor code...

What is the value of 'jToolBar' when it is used from the call point at line 56?

i m facing similar problems any help???

TurboPT · #6 17-Jun-2009, 11:05

Follow the stack trace from bottom->up.

I can't refer to exact lines, because you didn't post any code -- nor the dump, but the dump does provide the <file.java>:<line#> reference that should be easy to follow.

Java is typically pretty good at pinpointing the problem, but it's not always obvious, so if you still have trouble, post another reply with more details. (i.e. the dump and source)

Follow the guidelines about code posting, please, so that it will be formatted. (see the first two posts)

I've never used log4j, but if you can get the debug to also provide the file and line#, then that would be helpful.

Post #8, is a WARNing, it can't seem to locate an appender based on the message it gives. I don't know what to tell you for that one.

=============

Post #7. Although there appears to be no line#'s, (probably a log4j option that's needs to be applied, and I don't know what that needs to be), but following the dump that was given, it appears that the problem is AFTER this statement:

JAVA Code:

java.lang.Runtime.getRuntime().addShutdownHook(new TaxLotShutdownHook());
// (might be useful to have a try/catch around this, by the way, based on Java's API's info)

The next statement after that:

JAVA Code:

_password.addKeyListener( // Hint: how/where is '_password' initialized?

HTH.
