[jboss-user] [EJB 3.0] - Re: Entities in seperate jar files

[ALRubinger]

If there's any relationship between the entities in Jar1 and Jar2 (associations, mapped superclasses, etc), you'll have to reference the classes in Jar1's persistence.xml file under the "class" node:

DTD:
<!ELEMENT persistence (persistence-unit*)>
  | <!ELEMENT persistence-unit (description?,provider?,jta-datasource?,
  | 	non-jta-datasource?,(class|jar-file|mapping-file)*,
  | 	exclude-unlisted-classes?,properties?)>
  | <!ATTLIST persistence-unit name CDATA #REQUIRED>
  | <!ATTLIST persistence-unit transaction-type (JTA|RESOURCE_LOCAL) "JTA">
  | <!ELEMENT description (#PCDATA)>
  | <!ELEMENT provider (#PCDATA)>
  | <!ELEMENT jta-datasource (#PCDATA)>
  | <!ELEMENT non-jta-datasource (#PCDATA)>
  | <!ELEMENT mapping-file (#PCDATA)>
  | <!ELEMENT jar-file (#PCDATA)>
  | <!ELEMENT class (#PCDATA)>
  | <!ELEMENT exclude-unlisted-classes EMPTY>
  | <!ELEMENT properties (property*)>
  | <!ELEMENT property EMPTY>
  | <!ATTLIST property name CDATA #REQUIRED>
  | <!ATTLIST property value CDATA #REQUIRED>
