I asked about memory on the machine and about the command line arguments used to invoke your environment as a sanity-check to make sure that your Java VM (in this case Tomcat ?) is configured with a large enough heap to support your program. It could explain why your application runs out of heap. There are reasons WHY it requires this much memory, that we don't want to go in to here. Simply plugging in a few memory cards isn't enough. Java has to know the size of the heap (free store) that it is allowed to create. For the Sun Java, use the commands: "java -j" and "java -X" to see the options. In Tomcat 5, you could use the environment variable JAVA_OPTS to pass in a value for -Xmx, say "JAVA_OPTS=-Xmx800M" to allow an 800 Mb heap. This isn't a perfect solution, but it could help you get to the next level and keep you alive while you consider your commercial options. -- John Austin <[EMAIL PROTECTED]> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
