title: JAXB - Creating modules for reuse
body: <p>Does JAXB support modular code generation?</p>
  
  <p>Most of my background is with JibX for XML marshalling, but for legacy reasons our firm is using JAXB.</p>
  
  <p>One feature that was available for JIBX was <a href="http://jibx.sourceforge.net/fromschema/example-modular.html" rel="noreferrer">modular code generation</a>.  Say I have a main schema but I have several different envelopes for that schema.  With JibX I could create a jar file out of the JibX'ed core schema, and then in separate projects I could JibX my envelope schemas and simply point to the shared jar instead of having to duplicate the code generation of the core schemas for each envelope.</p>
  
  <p>I don't yet see a way for JAXB to handle this - has anyone been successful doing something like this?</p>
  
  <p>Thanks in advance,
  Roy</p>
