HI,
I am new to Castor and trying the example "http://www.ibm.com/developerworks/xml/library/x-xjavacastor3/". I created a web application and inside have a package as specified in the example and put all the files, Author.java, Book.java, BookMapUnmarshaller.java, book-mapping.xml, book.xml. I made a small change in book.xml to match my xml struture and when I run the file, BookMapUnmarshaller.java, I get the error
Book ISBN: null
Book Title: null
null
java.lang.NullPointerException
at javaapplication1.BookMapUnmarshaller.main(BookMapUnmarshaller.java:26)
Author.java
Book.java
BookMapUnmarshaller.java
book.xml
book-mapping.xml
