Hello List...
I tried to extend a existing webapp based on a own framework with some
actions using struts2.
After I added all necessary libraries, the struts2 filter and the
struts.xml I have some errors when the tomcat starts up. (see further
below)
Whats odd about that - I can call a defined action and in the debugger I
can see that the execute method is called. But when I try to access
properties of the action with <s:property value="MyValue" /> it is
empty. Trying it with <s:property /> shows the class
DefaultTextProvider.
Tried to find something about that issue on the list, but I am not sure
for what I should search.
The exception gave just a few responses, but with no clue how to fix it.
Thanks in advance!
