RE: [jBoss-User] Duplicate bean results in findByXX executionpro blem.

[Hardy, Patrick, DDI - Garden City]

I'm also having the same problem with findAll() where if there are rows in a
table, the collection will contain the first row of data 10 times. Not all
10 rows of data (or references to beans containing the 10 rows of data.)

After further investigation of the Lookup bean (LookupBean.java - associated
with Lookup.java), ejbLoad() is only called once. Is this correct? Shouldn't
ejbLoad() be called for every bean found? No beans were in memory at the
time of the initial lookup of the data records.

Thanks.

Source code:

Entity bean home interface snippet (LookupHome.java):

  public Collection findByClub_Id (String club_id) throws FinderException,
                                                RemoteException;


Entity bean remote interface snippet (Lookup.java):

  public LookupData getSourceKeyData() throws RemoteException;


Stateless session bean snippet (EditorBean.java):

          .
          .
          .
          Iterator iterator = lookupHome.findByClub_Id (club_id).iterator();
          while (iterator.hasNext()) {
          Lookup l = (Lookup)iterator.next();
          System.err.println ("source key: " +
l.getSourceKeyData().getSourceKey());

2 beans matched the criteria. Results of the println:

        source key: 017_06_cn_06_719_089K
        source key: 017_06_cn_06_719_089K

What *should have* printed:

        source key: 017_06_cn_06_719_089K
        source key: 017_06_cn_06_719_089L

Editor bean does a findByXX() with a given club identification and returns a
Collection of remote references to matching beans (correct?). Using an
iterator, run through the list of remote references and pull out the data.

Is there something I'm doing wrong? I am using JDK 1.3 & JBoss 2.0 FINAL.

Thanks.

That's strange.  How are you determining the identity of the returned beans?
Post the code + results...
