[jdom-interest] Out of memory Error!

[alex_pchome]

Hi All&Ian
     I try to type," java -Xmx64m"
In my cmd command line, but it doesn't work.
the message is====>
---------------------------------------------
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)
-------------------------------------------

Or I try " java -Xmx 64m"
the message is====>
-------------------------------------------
Invalid maximum heap size: -Xmx
Could not create the Java virtual machine.
----------------------------------------------
I don't know UNIX, so I guess "TOMCAT_OPTS" is environment variable.
So I put it into my W2000 environment variable setting, but still dones't
work.
Can anyone give more help.
Regard
                       Alex
