launching java programs

[tomcloyd]

Just migrated from WinXP to Kabuntu (7.10). I've been studying, searching and reading, and getting absolutely nowhere in my efforts to get these java programs running: jEdit, and Aptana Studio. I cannot even find any general documentation about this. In Windows, there is a load module - all setup gets done for you. Here, I unload a Linux download for, say jEdit, unpack it, and haven't a clue what to do next. There's no apparent way to launch it, and no documentation with the program to clear this up.

One thing I found said that if I have Sun's java VM loaded (I do, via adept), I can just use a command line "java {progr. name}.jar" - but I need to make sure "it" is in my path. What is "it'? What path (I cannot find documentation on that either)?

I'm surprised by the difficulty of all this, given the ubiquity of both java and linux.

Can any one give me some suggestions? I appear to need to worry about my path, and also need assurance that the "java {filename}.jar" thing is right.

Thanks!

Re: launching java programs

Install desired applications via Adept Manager (K Menu | Systems | Adept Manager). If the application you are looking for isn't listed in Adept Manger, it is probable that it isn't packaged for use in the version of *ubuntu you have installed.

The PATH is the list of directories which are searched when you request the execution of a program. You can check your PATH using this command:
echo $PATH
