[opencms-dev] OpenCms 6.2.3 installed on WebSphere 6 and Dynamic Cache Service enabled

[Kauppinen, Arto]

Hi,
 
We are trying to install and use OpenCms 6.2.3 on WebSphere ND 6.0.2.5
and Oracle 10g. WebSphere is actually installed as a part of WebSphere
Commerce 6.0 installation. OpenCms installation went quite nicely, I
installed opencms.war and after that I ran the installation wizard.
After installation I copied these JDK 1.4 support files to system. 
 
I have also changed the cache property to "bypass" for these files in
OpenCms: "/system/workplace/commons/property*.jsp",
"/system/workplace/editors/editor_main.jsp",
"/system/workplace/editors/fckeditor/filebrowser/connector.jsp".
 
My problem is that if I enable "Dynamic cache service" in WebSphere
(Application servers>server1>Dynamic cache service), I'll start to
receive "com.ibm.ws.cache.servlet.CacheProxyRequest" errors. Which are
actually "java.lang.ClassCastException" exceptions from that class. This
exception will be raised for example when I try to open "Cache
AdministrationTool" in OpenCms. If I disable "Dynamic cache service"
from WebSphere, then I'll not receive these errors, the problem is that
I need this cache service to be enabled.
 
What I need to do to get OpenCms work with WebSphere and "Dynamic cache
service" enabled?
 
Here is the complete stacktrace:

Any help would be appreciated.
