I am new to hibernate. I am running in some problem here. I hope someone out there will help me !!!!!

Here is the situation. I have a hibernate model object that has a byte[] property to store a blob column in database table. Actually I want to run a criteria api to do search in that table. My requirement is, I have to display other columns in that table and simultaneously I should be able to retrieve the blob for one or two rows on demand. But everytime I do a search, my development box hangs and throws the "out of memory" error. Since the blob is pretty huge that's why I suspect after loading the blob for each row, the system might have run out of memory and threw that error.

Now my question is, can I make the blob property of that model lazily initialized? As far as I know we can make the association lazily initialized. I tried putting lazy="true" in the mapping document for that property, but that did not help.

Thanks in advance.

For lazy fetching of individual properties you need build time bytecode instrumentation.

More information can be found in the performance chapter at http://www.hibernate.org/hib_docs/reference/en/html/performance.html in section 19.1.7 for Using lazy property fetching

Hope this helps
