null pointer exception

When I run the following code, I get this for output:
test2=after certifications
before calling certs=certs
before calling skills=sk
test3=after dates

If I comment out any references to req that occur after calling writeSkills, the program works. It seems that somewhere req is being set to null. Is there anything that I am missing?

I found the problem. I was not accounting for getParameterValues returning null.
It is sorta covered in the JavaRanch Style Guide.
