Seam3 Security - JpaIdentityStore Null pointer exception

[gmodeldriven]

Hi all,

I'm trying to create a simple applications uses a idm console module with seam3 and picketlink (seam 3.1.1 and picketlink-idm-core-1.5.0Alpha2).

In particulare i've recivede the following message error messagge:

Caused by: java.lang.NullPointerException

          at java.lang.Class.forName0(Native Method) [rt.jar:1.7.0]

          at java.lang.Class.forName(Unknown Source) [rt.jar:1.7.0]

          at org.jboss.seam.security.management.picketlink.JpaIdentityStore.bootstrap(JpaIdentityStore.java:292) [seam-security-3.1.0.Final.jar:3.1.0.Final]

          at org.picketlink.idm.impl.configuration.IdentityConfigurationImpl.createRealmMap(IdentityConfigurationImpl.java:192) [picketlink-idm-core-1.5.0.Alpha02.jar:1.5.0.Alpha02]

          at org.picketlink.idm.impl.configuration.IdentityConfigurationImpl.buildIdentitySessionFactory(IdentityConfigurationImpl.java:147) [picketlink-idm-core-1.5.0.Alpha02.jar:1.5.0.Alpha02]

          ... 105 more

Basically, the code inside JpaIdentityStore that present the null pointer is this:

     clsName = configurationContext.getStoreConfigurationMetaData()

                .getOptionSingleValue(OPTION_RELATIONSHIP_CLASS_NAME);

        try {

            relationshipClass = Class.forName(clsName);

        } catch (ClassNotFoundException e) {

            throw new IdentityException("Error bootstrapping JpaIdentityStore - invalid relationship entity class: " + clsName);

        }

It could be a problem in configuration metadata, but I don't know how fix it.. In details, where can I find a documentations about this ? I've red here that I need of insert a idm-config.xml file but I don't know where and how.

Any hint ?

Thanks in advance,

Gianfranco.

Ok... I solved... I miss the IdentityEntity annotation in IdentityObjectRelationship

@IdentityEntity(EntityType.IDENTITY_RELATIONSHIP)

@Entity

public class IdentityObjectRelationship implements Serializable {

   ....

}

Thanks anyway
