You can create a new thread at any time. Then if you so desire, let the 'main' thread die by letting the 'public static main' function return. If the thread you created is a 'daemon'...

Netbeans uses the Apache Ant build tool to do it's compilation. The Ant build.xml file Netbeans uses should create a jar in a directory called 'dist' under the project folder.

Hi,

No, the -cp flag works just the same under Linux. This problem is not classpath related though.

Hello,

Background

The reason you are receiving the 'UnsupportedClassVersionError' is because the 'bash' shell is finding the default installed 'java' bundled with MDK (Mandrake) 10. You can...

Hi Richard,


It is used as a path delimiter. Without it multiple specified paths would be parsed as one location.

You say you are running this code from the JProc folder. Why then include '.' in your classpath? as in this case '.' and 'C:\WINDOWS\Desktop\JProc\' will be one and the same thing. I am just...

Hi,

Have you tried increasing the JVM's Heap spaces? Research the '-Xms' & '-Xmx' command line parameters. Example:

Thanks jwenting,

Yes I have set the 'eden' heap sizes, using the '-Xms' & '-Xmx' arguments:
