Command line

Newbie & Debugging Questions
#1

Ok, suppose when i jar all my files i use command line and type this:

jar cf MyJAR.jar class1.class class2.class class3.class class4.class class5.class class6.class …

is there a way to put that whole thing inside a file and execute that file? instead of typing that every time?

#2

Dump that into a .bat file (make one in notepad) and add “pause” as the second line so you can capture output.

You might also consider using an IDE, like Eclipse, with Ant build files that you can write to do that kind of packaging (and a lot more ).

Thanx, Jon, it worked.

I use JCreator and it doesnt support jarring.

A simple way in Jcreator is to add a bat file as external tool: configure->option->tools->new->program than add a bat file like this:

makeJar.bat


pushd
cd classes
jar cf output.jar *
popd
pause

once you have done it, simply add this external tools to your toolbar:
right click on toolbar->customise select categorie “Tools” drag first tools icon to your toolbar.

you may also use/customise this tools http://www.java-gaming.org/forums/index.php?topic=17584.0 to make exacly what you want as for example read filename from a txt file as requiered by your first post.

#6

You could use

jar @arglist.txt

where “arglist.txt” is a file containing

cf MyJAR.jar class1.class class2.class etc

spread over multiple lines if you like. (See the jar tool documentation, e.g., http://java.sun.com/j2se/1.5.0/docs/tooldocs/windows/jar.html.)

But you may find that batch files may give you more flexibility.

Learning ant http://ant.apache.org/manual/index.html would give you a lot of flexibility and the accuired knowledge should be useful anyway, since it is pretty much standard for building/packaging java projects. I don’t know use JCreator (and would advice using Netbeans or Eclipse), but there is at least some ant integration mentioned on the features page (apparently pro only). Also adding the ant-execution via configure->option->tools->new->program might always be an option.
