I must not have re-deployed properly. It is working now. So now I have an example working with a hard-coded string literal ('sss') as a parameter. <s:button id="Test" action="#{IButtonMgr.writeSettingsP1('sss')}" value="Write Key"/> and: public void writeSettingsP1(String parm); Now I have to work on how to get a variable into the parameter. I tried a JavaScript call instead of the hard-coded 'sss' and that fails. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4057886#...
