Subject Re: out of memory error

Out of memory errors are not really all that uncommon
in Java, especially when you're working with
long-lived programs such as servlets.

Try adding something like this to your Java code:

Runtime rt = Runtime.getRuntime();
System.err.println("Heap size: "+(rt.totalMemory()-rt.freeMemory()));

This will print out the current size of the Java heap, and
give you some insight into how much memory you're really using.

Also, the Sun JVMs have a fixed maximum heap size, which defaults
to something like 16M, I think.  You might have to reconfigure
Tomcat to run java with the option:  -Xmx128m 
This will set the maximum Java heap size to 128 megabytes.
