I'm responsible for hosting a java Applet which has to use a lot of
memory and the SUN JVM.
Is there way to determine how much memory can be used by the jvm ?
I know the -Xmx and -Xms options but is there a way to find usefull

An application of ours is suffering OutOfMemory problems.
As we have suspicions that it's not actually running out of memory, we've
been searching for other causes than simply a too small heap or a fragmented
heap. We found some posts mentionning that allocating an excessive number ...

i want to write a program that reads an integer between 0 and 1000 and
summarizes all the digits in the integer. For example, if an integer is 932,
the sum of all the digita is 14.
Does anyone knows how to do this?

I got this from a customer. Has anyone seen extreme anomalies in GC times as
shown below?
All I know about the configuration is Solaris 9 / SPARC and 1.4.2_0x. The
behaviour is reproducible.

In resume, I have a factory class that creates/instantiates a family
of classes, like in this example:
public class Test{
   public static void main(String args[]){       

I'm a bit disapointed with the impact static variables can have on memory
usage (and leakage). Hope you can help with this two-fold question... :-)

we're having big trouble with our java processes growing and growing
in size. It's a servlet application being spidered by httrack and
involves heavy filesystem access and CORBA communication. No native
code except for the jdk's is involved.

I am not especially technically minded so this is a cry for some help
from someone with technical expertise and a way of putting it across
to the layman.
Here is my problem: I am unable to see, let alone use, the voice chat

I have searched to no avail on this question.
Does anyone know how to view the grapical (menu) output of a JAVA class

I am not interested in the code behind the scene, but rather the

Using JNI I can easily access COM functions through JAVA.
I want to be able to call Java methods through COM.
Is there a product/technology that can do this?

The VM spec says in chapter 4.8.2, Structural constraints:
The arguments to each method invocation must be method invocation
compatible (§2.6.8) with the method descriptor (§4.3.3).
And 2.6.8 reads:
