Does anyone have an example of a JBoss 3.2 implementation of an CMP entity bean that needs a compound primary key (and thus a PK class)?
JBoss is finding my PK class (class is instantiated (0-arg constructor) during deployment of my entity bean JAR, but the resultant SQL has no field/column names or values.
Any ideas, or working examples I can look at? ejb-jar.xml, java code, etc.
TIA
