finder using cmr fields - EJB-QL error
Hi,
Im getting the following error when deploying to jboss 3.2.1
I'm using Eclipse and the plugin for jboss and xdoclet.
org.jboss.deployment.DeploymentException: Error compiling EJB-QL statement 'SELECT s.serviceBinding from Subscriber s where s.subscriberId = ?1'; - nested throwable: (org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "s.serviceBinding" at line 1, column 10.
Was expecting one of:
"DISTINCT" ...
"OBJECT" ...
<NUMERIC_VALUED_PATH> ...
<STRING_VALUED_PATH> ...
<DATETIME_VALUED_PATH> ...
<BOOLEAN_VALUED_PATH> ...
<ENTITY_VALUED_PATH> ...
<VALUE_CLASS_VALUED_PATH> ...
)
The corresponding finder looks like
ServiceBindingsEntityBean.java:
* @ejb.finder
* signature = "java.util.Collection findServiceBindings(java.lang.String subsId)"
* view-type = "both"
* description = "Find All service bindings for a subscriber"
* query = "SELECT s.serviceBinding from Subscriber s where s.subscriberId = ?1"
.....
/**
* @ejb.interface-method view-type = "local"
* @ejb.persistent-field
* @ejb.relation name = "subscriber-service-bindings"
* target-ejb="Subscriber"
* role-name="subscriber"
* target-role-name="service-bindings"
* @ejb.value-object
* @jboss.relation fk-column="subscriber" related-pk-field="subscriberId"
*/
public abstract SubscriberLocal getSubscriber();
/**
* @ejb.interface-method view-type = "local"
*/
public abstract void setSubscriber(SubscriberLocal local);
and in
SubscriberEntityBean.java:
/**
* @ejb.interface-method view-type = "local"
* @ejb.persistent-field
* @ejb.relation name = "subscriber-service-bindings"
* target-ejb="ServiceBinding"
* target-role-name="subscriber"
* role-name="service-bindings"
*
* @ejb.value-object
* aggregate="com.alopa.metaserv.core.intf.ServiceBindingValue"
* aggregate-name="ServiceBinding"
* members="com.alopa.metaserv.core.intf.ServiceBindingLocal"
* members-name="ServiceBinding" type = "Collection"
* relation = "external"
* @jboss.target-relation fk-column="subscriber"
* related-pk-field="subscriberId"
*/
public abstract Collection getServiceBinding();
/**
* @ejb.interface-method view-type = "local"
*/
public abstract void setServiceBinding(Collection d);
.....

For some reason it appears the serviceBindings field does not appear to the server as an an entity.
I am new to EJBs and I must be missing something. I can't figure out what.
PS: Is this the right forum for such questions? I had tried the beginners forum, but got no response.
