 Seems pretty obvious to me: buy or allocate more RAM to your 
 appserver  
 if you really
 want to manipulate such large tables in memory.
 Else use more advanced collection implementations or DB that won't  
 create all objects in memory at once.


if you already have enough ram, you still have to tell the jvm
that it's allowed to use it. Therefore use the environment
variable JAVA_OPTS. On Linux in my catalina.sh script i added
a line like this:

JAVA_OPTS=${JAVA_OPTS} -Dsun.net.client.defaultConnectTimeout=200 -Xmx512m

That gives the jvm a maximum of 512 MB RAM.

BTW: in development i experience, that after i compiled and deployed  my portal
several times on tomcat 4.1.x, which works fine without any restarts, i evetually
get Out of memory errors anyway, which i can solve by restarting tomcat.

Ok, I calculate the dimension of the object. This
object need 1.4 mb of RAM. It's too bigger! It was the
problem

Thanks!
