Re: [JBuilder] Multiple packages per JAR

[Miles Parker]

Yep, I agree w/ Nick. I've heard of problems in the past with resolving the 
same package hierarchy across multiple jars, but not the other way around. 
Maybe this is just because most packages are in the same bottom-most 
directories (ie com.mycom.blah.blah) but I don't think so. Sounds like the jar 
file or your JBuilder settings may somehow be messed.

VC is a little more striaghtforward, you just include the jar in a list of 
input class files. I imgaine this just sticks them in the class path. This is 
all you should have to do; there's nothing really to 'install', you just have 
to let the vm know all the places that a package hierarchy might be located.

OT: Of course, perhaps JBuilder does things its way so that it can have the 
info it needs when deployment time comes. But I don't really trust these tools 
to do my deployment anyway. Its funny, the more I use these IDEs, the more I 
find myself using them as glorified text editors, and doing the complicated 
stuff with batch [simple make] files. Its not like debuggers are very helpful 
anyway, so I'm beginning to think an IDE doesn't add a _huge_ amount of value 
for me. At least you always know what's happening when you're calling the 
compiler directly.

Historically, figuring out class paths was the hardest thing for people to get 
a hold on in Java. It just seemed to create endless confusion and frustration, 
but jars have really helped to rationalize things.

That's exactly how I install any jar'ed collection of files. As you say,
installing the jar installs all the packages in that jar as a single
library. Whenever I include that library with Project/Properties/Add
JBuilder can then see all the packages. Seems like it might be something
funny with the jar you're working with.
