Hi,
I'm having fun coding a JAVA plugin! I'm having difficulty in coding to cope with the navigation of all children of a parent in the message tree though! The docs that are supplied and the JavaDoc aren't really that useful! Anyone got any "special" IBM documentation? My specific problem just now is that if I do:
MbElement Cursor = .....getFirstChild();
while (cursor.getName() != null)
{
...
cursor = cursor.getNextSibling();
}
Then I get a null pointer exception (on the getNextSibling call) when I get past the last child of the parent...
Help!
Regards,
Derek. |

I believe that getNextSibling() returns 'null' if there is no sibling. The condition in your loop will be trying to call a method on a null reference which will cause your exception.
Try changing your code to say
while(cursor != null)
{
...

I'm sure I tried that...I'll give it a bash though!
Thanks,
