EJB 2.0 CMP and jbosscmp-jdbc.xml

[matt_hannay]

Can some one tell me which version of the jbosscmp-jdbc.xml corrolates to which RC of jboss3.0

It appears that the xml in the jbossCMP WorkBook do
not corrospond to http://www.jboss.org/j2ee/dtd/jbosscmp-jdbc_3_0.dtd

For example work book says <forign-key-fields>
but the dtd says <key-fields>

which am I suppose to use?????

I am still getting some deployment problems
See attached??

I have also upgraded to jboss3.0RC3

I have 2 beans with a unidirectional M->1 relationship
i.e players->team
I have deployed each of the EJB in seperate jars.

the team bean deplys fine (but the jbosscmp-jdbc.xml
file is as per the xml in the CMP workbook)

the player bean gives the error as in the capture.log
and below. (The jbosscmp-jdbc.xml is as per the jbosscmp-jdbc_3_0.dtd)

I can deploy the beans with out relation ships and query/update the database, no worries.

Hi matt
I have had this problem too.
The examples in the cmp workbook are well out of date- I have found it's best to ignore them and work from the latest dtds now.

[matt_hannay]

All the DTD's now confirm too the new DTD, but
I am still getting the same Exception

[matt_hannay]

I have an entity bean drployed to jboss3.0RC3
I could deploy it with the old DTD now I use the
new DTD and get the following NullPointerExceptions

I do not have any empty fields in the xml.

Any Idears!! I have none! other than jboss may not be pharsing the xml file to the DTD.
