I am getting a "ClassNotFoundException" for a "composite-id" element in a hibernate mapping file during deployment of a hibernate app even though the class in question does correctly exist in the GGGoMobile.jar file.
I am using
NetBeans 6.7.1 Hibernate utilities to reverse engineer a
MySQL 5 database and generate the mapping files,
JBOSS 5.1.0, and
Hibernate 3.3.1.
Application Structure:Code:
GGGoMobile.ear
+META-INF
+ gggomobile-hibernate.xml
+ application.xml
+ jboss-app.xml
+GGGoMobileLib.jar (contains all hibernate mapping files and compiled .class files)
... other JAR and WAR files
