I am working on itext pdf when I am extending a PdfPageEventHelper class it is showing following errror. 

Base class com.lowagie.text.pdf.PdfPageEventHelper (super class of 
de.fu_berlin.inf.klausurenportal.pages.question.TableHeader) is not in a controlled package
 and is therefore not valid. You should try moving the class to package 
de.fu_berlin.inf.klausurenportal.base.

  • Classes that have my name (Lowagie) in their package name are obsolete and should no longer be used. Please upgrade to a more recent iText version. – Bruno Lowagie Apr 02 '13 at 06:39

It seems that your component is extended from com.lowagie.text.pdf.PdfPageEventHelper class that is not within the tapestry controlled packages. All super classes for tapestry5 components and pages should be placed within root.base package.

http://tapestry.apache.org/component-classes.html#ComponentClasses-ComponentPackages

But you can implement PdfPageEvent interface instead. You can even create something similar to PdfPageEventHelper class in root.base package and extend it.

But do you really need this class in your component? You can use PdfPageEvent implementation as a separate class, e.g. as an inner class of a page or as an utility class.
