Obviously, something must be wrong if something as simple as setting an action property doesn't work. Are you sure that the url to the action is generated correctly? Try using the s:url tag instead of assembling the url and parameter "by hand". Also, you have not showed your struts.xml.
I suggest you start again from the beginning, remove everything, just leave a simple action with the execute method, the getter and the setter for the property, nothing else. Then get that to work. You can also use the bootstrap tutorials as a starting point.
