[opencms-dev] Several errors with OpenCms 8 on Websphere 6.1, JDK 1.5

[Mathias Lin]

We plan to move a OpenCms 7 website to OpenCms 8, on Websphere 6, JDK 1.5.

While everything works fine on an environment:
a) OpenCms 8.0.4, JDK1.6, Tomcat6, MySql, as well as
b) OpenCms 7.0.5, JDK 1.5, WebSphere 6.1, Oracle

we face some errors on
c) OpenCms 8.0.4, JDK 1.5, WebSphere 6.1, Oracle

There are a few problems we're seeing, 3 different errors at different
locations. The installation runs through smoothly, but:

(1) opening the index.html of the OpenCms default demo site from
within the workplace throws an error:

(2) Furthermore, none of the files' advanced properties can be opened
from within the workplace. Trying to edit the advanced properties of
any file within the VFS results in error:

(3) Trying to view some of the pages of our imported website in the
preview fails with an exception:

Do these error messages look familiar to anybody?

Thanks for any hint.
