(Note that localProcessorGroup is not declared in your code snippet.

The code for setLogFile might be useful. Oh, and the stack trace of the
original exception.

What does this line of code print to the log file? Or, does nothing
print because the log file has not been correctly configured?

*Sigh*... why can't people use standard logging facilities instead of
using their own?

Yeah, this really should be changed to getResourceAsStream instead of
using a FileInputStream, though since you don't have the original code
it might not be a good idea to mess around with it.

Do you get a stack trace along with the error?

This could be a problem: the use of a forward-slash on a DOS/Windows
filesystem may not get you the desired results. In other code above,
File.separator (and File.pathSeparator) was correctly used so that it
would work on any platform. /This/ line of code uses / and : without
regard for the platform, and is likely to confuse Windows. On the other
hand, nobody here knows what getPathsFromList will do.

If the files are really in /opt/mywebapp/loan/abc.props, then you did
you tell web.xml that they were in [path to webapp]/WEB-INF/config? Just
tell your servlet where the files really are!

Then you need to move them.

If you are using /WEB-INF/LOAN/abc.props then you need to use
<param-value>/WEB-INF/LOAN/abc.props</param-value> instead of
<param-value>/WEB-INF/config/abc.props</param-value>.

The path of the file it's trying to read would be immensely helpful. Can
you post a full stack trace please?

You should be able to view the complete, decompiled source code...
