appmsg is backingBean,"commandAction1" is a setCommandAction1 getCommandAction1 variable,not a method, I put a value like "#{app1.method1}" string to commandAction1 on application ,
eg:
appmsg.setCommandAction1("#{app1.method1");
<h:commandLink action="#{appmsg.commandAction1}" value="#{appmsg.commandValue1}">
</h:commandLink>
the action infact is #{app1.method1}
how I to do?

However I can't understand why you want to do so,
you can do so by developping your own Application Action Listener.
The default Application Action Listener does something like as follows:MethodBinding bind = ((ActionSource) event.getComponent()).getAction();
String outcome = (String)bind.invoke(fctx, null);
nhandler.handleNavigation(fctx,bind.getExtressionString(),outcome);
fctx.renderResponse();Instead, your Application Action Listener may do as follows:UIComponent comp = (UIComponent)event.getComponent();
String actionString = (String)comp.getAttributes().get("action");
String action  = (String)app.createValueBinding(actionString).getValue(fctx);
MethodBinding bind = (MethodBinding)app.createMethodBinding(action,null);
String outcome = (String)bind.invoke(fctx, null);
nhandler.handleNavigation(fctx,bind.getExtressionString(),outcome);
fctx.renderResponse();
