Weblogic servlet error

[Guest_imported]

Hi everyone,
I am struggling with this weird form of error that I have not been able to resolve. I am getting this null pointer exception on a line(64) that has no nulls. I verified this by checking the values. Even though I am getting this error, the application performs normally, successfully downloads a file in this case. I have deployed my application on Weblogic 6.1 SP3.Can anyone throw some light on this?
Thanks in advance.

Null pointer exception...that says it all. You are trying to dereference an object pointer that hasn't been initialized. Refer to the line mentioned in the stack trace and find out why this object is not initialized.

I do initialize the variable. I do a system.out.println on that variable too and it displays a non null value. That is why I fail to understand why I am getting this problem. Is it weblogic specific? is there a problem with the servlet container?

Thanks again.

You'll have to show us the offending code.
