Hello,
thanks for your contribution. But how I already said we have seen that the first error message:
The error is: javax.servlet.UnavailableException: Cannot load a validator resource from '/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml'
But behind that message is an additional message that describes the real root cause of the problem:
SEVERE: Cannot find resource "org/apache/commons/digester/xmlrules/digester-rules.dtd"
org.apache.commons.digester.xmlrules.XmlLoadException: Cannot find resource
"org/apache/commons/digester/xmlrules/digester-rules.dtd"
Unfortunately we have no idea why the dtd file can not be loaded. The appropriate line of code is:
getClass().getResourceAsStream("<link_to_resource")
And this returns a NULL object. The NULL object causes the general exception and finishes the instantiation of Struts.
Any additonal hints?
Regards, Maik
