Is IT A BUG ? Error deploying only last Entity bean of ejb-j

[sharma_arun_se]

Dear Jboss Guru,

I am facing deployment problem with my application. Jboss is unable to deploy my last Entity bean. No matter even if u change the order of entity in ejb-jar.xml , only the last one cannot be deployed successfully, although others are ?
What is the cause of problem. I read it some where that it is bug in JBOSS? is it true , if so what is remedy ?

Many Thanks in advance .....

[aloubyansky]

Interesting... Looks like an entity has no fields?

[sharma_arun_se]

Yes , We have one entity which have no field , I am sending you the tag entry of that in ejb-jar.xml file.



<ejb-name>NextIDBaseEntityEJB</ejb-name>
<local-home>au.com.chimo.nextidserver.base.LocalNextIDBaseEntityHome</local-home>
au.com.chimo.nextidserver.base.LocalNextIDBaseEntity
<ejb-class>au.com.chimo.nextidserver.base.NextIDBaseEntityBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
False
<cmp-version>2.x</cmp-version>
<abstract-schema-name>NextIDBaseEntityEJB</abstract-schema-name>



Is Anything wrong in this . IF so pls suggest way out as this is our base entity , whose functionality is subclassed by all our entity.

Well thanks very much for your response at last .

Pls reply soon.
bye and take care .

Arun K Sharma

[aloubyansky]

Yes, that's wrong. You should define at least a primey key field.

[sharma_arun_se]

Yes we are creating one primary key cmp field for that entity.I think then it is necessary to make change corresponding entity also . Then test with our client appalication.
I will let u know the response what pls stay in touch ........


well thanx for everthing
