Hello together,
I like to implement few servlets with struts2. The problem is, that I
gets always a exception. See below this message. Every servlet has a
struts.xml and log4j.properties file.
When I start the servlets on itself, I get no start up problems but when
I will start all servlets together, following exception interrupt my
process.
Any ideas?
