In this chapter, we converted an EJB 2.0 entity bean to an EJB 3.0 entity bean using
XSLT transformation. We used the built-in JDeveloper XSLT transformation tool
for the XSLT transformations. The XSL stylesheets may be modified to convert
entity EJBs developed with earlier versions of EJB specifications to entity beans for
later versions of the EJB specification. For example, an EJB 2.1 entity may also be
converted to an EJB 3.0 entity.
