Answer 1

You are getting java.lang.NoClassDefFoundError because of missing jar with class definition.

You need to add FontBox jar to your classpath.

Answer 2

According to your comments to @user1951544's answer you seem to use a very old PdfBox version 0.7.3. This very likely is not cooperating well with the current FontBox jar. I would advice updating to the current state.

In that case you should also consider the other hard dependencies required by fontbox:

The main PDFBox component, pdfbox, has hard dependencies on the fontbox and jempbox components and the commons-logging library.
