First off, the Java support in the kernel doesn't mean that the kernel can execute Java bytecode. It just means that the kernel can recognize the magic number for a java class and call the java interpreter. You still need to have a java interpreter installed for it to work. HK> First, Welcome.class isn't executable.

It's just hacks in the linux kernel that allow you to 'run' class files. So it doesn't really know it needs to set the x bit. The reason /usr/bin/java doesn't exist is because you don't have a java interpreter installed. guavac doesn't include one - it's only a compiler. HK> Am I missing something?

Install kaffee or or the java development kit (jdk-static or jdk-shared). Both of them contain java interpreters and you'll have /usr/bin/java and be able to run java classes, either through the kernel support, or by runnning "java Welcome.class" (Which is what the kernel does - the 'support' was just put in there because someone thought it would be fun to say Linux has support for java executables :) -Larry -- Larry Daffner | Linux: Unleash the workstation in your PC!
