Yes, this is internal to the appserver , and vendors will prefer not to interfere with this for optimization and other purposes.

This is, as Ashwani mentioned, internal to the App server and unless the container vendor gives a configuration option, cannot be altered. I am curious to know why you would want to remove entity beans from the memory. IMHO, you must try increasing the bean pool size(if you think that's going to be an issue). Any specific reasons other than that? Harish Ashwani Kalra wrote: >Here is how finder method works.
