java and linux redhat 9


I'm a first time user in linux and I have a couple of questions. First would a java sdk and jre be installed with redhat 9 already or should i install one. Next how do i add the java to the environment variables. And lastly how to i do similar commands in linux as i would in windows, the ones i need to know first are run->cmd, javac myprogram.java and run->cmd, java myprogram

Thanks!

I am pretty sure fedora does not come with the java SDK...some distros like slackware do though. You will have do download the .bin or .rpm file from sun and install it (instructions on site) after installing it run this command

export PATH=$PATH:/path/to/java/stuff

and it will load your required commands.

run->cmd is the system menu (start menu thing) then navigate it till you find something called "terminal"

other than that all java commands are the same as windows.

Do i just run that in the run command and it will take care of adding the environment variables?

Im not sure what you mean by "environment variables." If you mean it adds the java, javac, etc. commands to the command line then yes. Also you have to replace the /path/to/java part with the real path to the java files. Search for "javac" w/ the red hat searcher program thingy and it is probably whatever folder that is in.

hello!
Redhat linux 9 is having a java compiler gcj (GNU compiler for java). u can get more about it from man pages and http://gcc.gnu.org/java/.

Or u can downlaod j2sdk for linux as rpm from sun.java.com (i am using this.)
ucan set the env variables by editing /etc/profile

PATH=$PATH:/usr/java/j2sdk1.4.2_04/bin

export PATH ..........

after downloading the java version of choice you should take a look at eclipse www.eclipse.org it saves you a lot of trouble using vi as java editor and the commandline for compiling and debugging
