[Aperture-devel] Xerces Class Not Found

[Keith R. B. <kbe...@bb...>]

Hi, all.  I'm using Aperture in a project, and some of the documents =20
that parsed successfully while testing Aperture alone now do not work =20
in the context of my project.  The error I get is:

java.lang.NoClassDefFoundError
      [java]     at =20

ry.java:281)

a:1383)

Any clues as to what's going on?  I did some research, and someone =20
said it could be because my project is loading a different version of =20
Xerces that does not have that class.  I think JDOM is being used, and =20
it uses xercesImpl 2.6.0.

Has anyone seen this problem before?  Do you have any suggestion what =20
to do about it?

Thanks,
Keith
