As per recent messages about classloading in the Digester, below is a patch for the Digester... One other possible effect that has not been discussed is that there may be a few environments where Class.forname() would work, but the context classloader loadclass() variant would not, due to security restrictions on obtaining the context classloader. This is a common operation and should not be an issue, but if it is, the could could try the context classloader approach, and simply try the Class.forName approach on any SecurityException caught...
