Has anybody had luck lazy loading a single field from a table? I have a table which stores binary data which can get quite large. I would like to load the records from that table without loading the binary field. I would like the binary field to be retrieved only if specifically asked for through the bean (myBean.getBinaryData()). Has anybody been able to accomplish this?


Thanks for any help.

Hi Tom,

I have exactly the same problem. I tried to put in load-groups, but no luck -- the whole record (object) is retrieved in the bean.

Any chance that you found out the answer to this problem?

Anybody?


TIA,

Anyone from JBOSS? We have the same problem, and I'm thinking I might split the table into two tables. One with the meta data and the other with an ID and the binary field to get around this problem.

thx..

Never mind... I figured it out... between adding lazy-load groups, eager load (and the important part), setting a <read-ahead> of the eager-load-group after the it works.

If someone needs more detail, send me email and I can send you our example.
