Dear list,
I am trying to get the ValueObject generation working for CMR fields as
described in the ValueObject documentation, but I am getting an error in
XDoclet's code generation. If anybody can tell me how to fix this error I
would be most grateful.
BTW I am using 1.2b2 built from the binary, with ant1.5.1
I have added an entry almost identical to the example (and to xpetstore)
to my file Person.java :
/**
* Get the Addresses for this Person
* @return Collection of Addresses.
* @ejb.interface-method
* @ejb.relation
* name="person_address_1_to_n"
* role-name="person"
* @ejb.value-object
* compose="rpmaster.server.data.beans.AddressValue
* compose-name="Addresses"
* members="rpmaster.server.data.beans.AddressLocal"
* members-name="Address"
* relation="external"
* type="Collection"
* @jboss.target-relation
* related-pk-field="personUId" fk-column="person_id"
*/
public abstract Collection getAddresses();
when I am running XDoclet I get an error here :
[ejbdoclet] Generating Value Object class:
'rpmaster.server.data.beans.PersonBean--> rpmaster.server.data.beans.PersonValue'.
[ejbdoclet] (TemplateEngine.invokeMethod 490 ) Invoking method
failed: xdoclet.modules.ejb.entity.PersistentTagsHandler.forAllPersistentFields,
line=19
of template file:
jar:file:/opt/dev/rpmaster/lib/main/xdoclet-current/xdoclet-ejb-module-1.2b2.jar!/xdoclet/modules/ejb/entity/resources/valueobject.xdt
[ejbdoclet] java.lang.reflect.InvocationTargetException
further down the trace it gives this indication as to why that method
failed:
[ejbdoclet] Caused by: java.lang.NullPointerException
[ejbdoclet] at
xdoclet.modules.ejb.entity.PersistentTagsHandler.isValueObjectField(PersistentTagsHandler.java:84)
[ejbdoclet] at
xdoclet.modules.ejb.entity.PersistentTagsHandler.forAllPersistentMatchedFields(PersistentTagsHandler.java:420)
for the full stack trace please see:
http://www.busquelo.org/XDocletStackDump.txt
When I remove the value-object tag from that method, XDoclet runs without
any errors. Anybody know what I'm doing wrong ???
Thanks
Nat
