Any idea how to fix this?

    Is the library being exported along with the rest of your code? Assuming you’re using Eclipse, If you right click on the project -> Properties -> Java build path -> Go to the “Order and Export” tab and make sure the Jama library is checked.

    If it’s not, the library isn’t included with the rest of the project when it is built, which is usually what leads to things like “Class not found” errors.
