Subject: Heap Size


>I have an application that on occasion gets large objects (megabytes) from
>the database. This leads to the occasional out of memory error. I also
>suspect that I have some memory leakage so heap size also goes after a
>period of time.
>
>Is there any way from within a JSP page or servlet to measure the current
>size and free space in the heap? At least this way I'll be forewarned and
>can restart the application.

>Thanks,
