Hi,

I have a simple query running that produces a list of entities. The entites seem to be javassist proxies, but how do I 'un-proxy' them?

Session sess = Util.getHibernateSession(em);
Query qry = sess.createQuery("select p from Person p where p.lastName = 'Smith'");

List<Object> people = qry.list();
for(Object obj : people) {
System.out.println(obj.toString());
}

-->
[Ljava.lang.Object;@2692c09e
[Ljava.lang.Object;@4897002a

Any ideas?

Hi,




These seem not to be proxies but rather Java arrays, which is odd though since your query selects the entire person object and not a projection of its attributes. You could inspect the output e.g. using Arrays.toString(), it would be interesting to know the array contents. Also, which version of OGM and which backend are you using?

Hi Gunnar,

Thank you for your reply.

Yes, you are correct, each item in the returned list is an array. Each array is of size 1, containing the (javassisted proxy to the Person found). So I can get the result I desire, but obviously something amiss.

Of note is that qry.getReturnTypes() produces a single item item array containing a org.hibernate.type.ManyToOneType(com.trainasone.app.vaadin.person.Person)

I'm using hibernate-ogm 4.0.0.Beta3, and infinispan 5.3.0.Final

Anything else I can do, or other information I could provide to help get to the bottom of this?

Best regards,

Sean

Hi sean,
could you provide a test?

Davide

Hi Davide,

Yes I will put a test case together. I presume a zip/tarball of a test maven project will be acceptable?

Thanks,

Sean

Hi Sean,

Yes, either that or just post the code here. The more concise the test case the better :) Thanks for your efforts, its much appreciated.

Davide, Gunnar,

I have a test project for you. Cannot see an upload option to attach it to this forum though. Where would you like me to put it?

Regards,

Sean

Hi Sean,

I can confirm the issue and have filed https://hibernate.atlassian.net/browse/OGM-346 for it. You can attach your test case to this issue.

As a workaround, just omit the "select p" part from your query, i.e. execute "from Person p where p.lastName = 'Smith'" instead. This will return a list of Person objects.

Thanks for spotting this problem,

Hi Gunnar,

Project attached to JIRA and thanks for the work-a-round (it does indeed work)

:D
