I would like to include a some java jar libraries for use as part of a sketch. Where should I put the jars such that they can be (1) used by my sketch in Processing and (2) automatically copied during export?

For (1), I see I can use "import" for an arbitrary java class. So, it seems to be an issue of getting the jars to be in the classpath somehow. I tried putting the jars in the sketch directory and I created a "lib" folder under it. No luck.

I'm new to processing, so apologies in advance if this was answered elsewhere (I looked).

Thanks,

Just use "Add File..." under the sketch menu, and select the .jar file that you want. This has the effect of adding it to a folder called "code" that will be a subfolder of your sketch.

You don't need to do any imports, they'll be magically added so long as the .jar is in that code folder.

And the same is the case for native code (.dll, .so, or .jnilib) to go with a .jar file if that's what you're up to.
