Getting java.lang.NullPointerException on File I/O

[brainchild1977]

Hello,
Am gettting this error on my email java application. The app utilizes some properties files to get certain parameters. I have checked all paths to make sure they are correct. I wonder if it has to do with incompatible jars such as xerces or xalan. The application was pre-compiled using sun's 1.4 jdk version. The server the app was deployed to is using ibm 1.4.2 jdk..

any ideas? Thx

Here is the complete stack trace:

Exception in thread "main" java.lang.NullPointerException

It's difficult to know without some code or an idea of what are you trying to read, but at first sight it doesn't seem to be an external jar problem.

Which JRE are you using?

Cheers,
