java.lang.NoClassDefFoundError occurred.

Hello,

I am not a Java expert but my application is using java to generate some reports. I am getting the above error when I try to generate some graphical reports. I am not sure where to start looking at this problem, can someone provide me with some insight...

I am running Sun OS 9.0

# 1

first result on google:

Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.

please, post more information about your error. Copy here the compiler's output.

Bye!

Yes. Specifically, post the printStackTrace()...That's the ugly looking pile of text that came pouring out onto the console window...If it's really big, just post the first one...hth,adym
