I have installed the Java3D API and the documentation. Here is where I got the documentation from:
http://www.oracle.com/technetwork/java/javase/tech/index-jsp-138252.html
now, i followed these instructions to install the JavaDoc for Eclipse:
JavaDoc in an Eclipse Android Project
I set the path of the documentation for the jars to the location of the documentation on my computer. When I click on an Object name in Eclipse, the popup window pops up, but it says “Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found.” Is there anything I’m missing here? It would be a lot more convenient if the info could just show up in the popup window instead of me rooting through the documentation by hand.
edit
this is that my eclipse looks like right now:

Here is what i have the path set to:
http://download.java.net/media/java3d/javadoc/1.5.2-latest/
Still no luck, i still get the same popup saying it can’t find the javadoc.
Normally that should do the trick, but I’ll just try to rephrase the instructions you have previously followed, maybe you missed a step:
Java build pathin the tree on the leftLibrariestabEditbutton and select your zip location inArchive pathjava3d-1_4_0-doc. You should add that to thePath within archiveinput boxThis should set you up. You could also extract the archive to a desire folder or use the online URL (the one that bitwave suggested, but please be aware that you’ll be needing a constant internet connection to access it) and specify whichever you want in the
Javadoc URLinput box.Cheers
