title: Install [java library] in Eclipse
body: <p>I just downloaded Eclipse several hours ago, and needed to add Java3D to the classpath. Installing it went without a hitch, but Eclipse can't seem to find the documentation folders so that it can give super-IDE functionality, such as autocomplete and method signatures.</p>
  
  <p>While I know how I would add them individually, this lead me to the question; what is the "correct" way to install a Java library in Eclipse? Is there a special directory format I should follow? Is there a plugin that already did this for me? (The answer to that is <a href="http://java3d-eclipse.sourceforge.net/" rel="noreferrer">yes</a>, but I don't know how to use it, or whether or not it's appropriate).</p>
  
  <p>Thanks!</p>
  
  <p><b>Edit 1:</b> It seems to me that someone down-voted the question. May I ask why?</p>
  
  <p><b>Edit 2:</b> So after monkeying around with the JARs, it seems that manually setting the doc path for each JAR in the library seems to be the least-error prone way.</p>
