Hello

Our web application works well with 1.4.1, but with 1.4.1 SR1 we get the
following exception:

[2003/11/26 10:57:23] Provider null could not be instantiated:

[2003/11/26 10:57:23] can't load servlet `log4j-init'

and the website doesn't work. I guess there has been some internal
change in the XML parsers of 1.4.1SR1 but we still are unable to find a
solution for this issue.

We would like to stress test SR1 as soon as possible to use it in
production servers.

Any tips?

Best regards

The following properties files have changed between 1.4.1 GA and
1,4,1 SR1:
sdk/jre/lib/jaxp.properties
sdk/jre/lib/xerces.properties

Try uncommenting the lines at the bottom of these file.
