Hi,
I'm trying to create a jar file. I have the tutorial in front of me, but something is messed up. I am typing:
jar cfm MyJar.jar Manifest.txt MyPackage/*.class (obviously with the appropriate package) into the command line.
However, it tells me 'jar' is not recognized as an internal or external command, operable program or batch file.
What does this mean? Do I not have JVM installed or something?
Thanks for any help,
Dan
Hi,
Hmm, I may have JRE installed instead of JDK. I'll check tomorrow morning when I get to work.
Just wondering, is there a certain directory I need to run the 'jar' command from? I've been trying from my package directory...do I need to run it from the java directory or something?
Thanks,
Dan

What directory would that be? What directory must I run the commands from? I've been using Eclipse to run my Java apps, not javac. I've tried exporting a jar file with Eclipse, but that hasn't worked for some reason.
Is there a certain directory I must run these commands from?
Hi,
Never mind the PATH variable, I figured out how to do it.
However, when I create my jar file, it tells me it can't find the main class.
"Exception in thread "main" java.lang.NoClassDefFoundError: jena/GUI"
What does this mean? I can compile the java file into a .class file fine, and I can run it as a java application using Eclipse. What is it talking about?
EDIT: I opened my jar file with winzip, and it includes everything necessary, I think. It has the manifest file, and all my .class files from the jena package. Here is the command I used to create it:
c:\sun\appserver\jdk\bin\jar cfm MyJar.jar c:\kdb\jena\Manfiest.txt c:\kdb\jena/*.class
