OpenSAML user discussion

[Brent Putman <>]

Hi Maicon,

No, you don't need to change the config files, but looks like you're
using Sun's JDK, the com.sun.org.apache.* classes  indicated in the
exception give it away.  You do need to be sure and endorse the latest
versions of both Xerces and Xalan as described here:

https://mail.internet2.edu/wws/arc/mace-opensaml-users/2006-04/msg00038.html

From our SVN, you can get the ones we currently use from
/thirdparty-lib/xerces and /thirdparty-lib/xalan.

Be sure to also remove any other Xerces and Xalan jars that you may have
in your classpath or endorsed dir (wherever the latter may be for your
environment).

I thought we had this info more centrally on the Wiki somewhere, but I
couldn't find it anywhere.  We'll add that to one of the introductory or
installation oriented pages.
