Iam using jdev 10.1.2 for my simple struts application
I have
action class -- LoginAction
form bean -- login (using DynaActionForm)
login.jsp to enter username
success.jsp for welcom msg
failure.jsp --- in this i use one submit btn when i press this it will go to login.jsp for relogin
<form action="/login.jsp">....
the problem is
In LoginAction
String password=(String)((DynaActionForm)form).get("password");
// String pwd =request.getParameter("username");
if(password.equalsIgnoreCase("oracle"))
return mapping.findForward("success");
else
return mapping.findForward("failure");
iam import all the class for the respective reff variables.
But it will indicate err underline(blue) under text which are in bold saying msgs as
--method get(java.lang.string) not found in org.apache.struts.action.DynaActionform

Well if you are just starting with JDeveloper - why are you starting with an old version?
You should start with 10.1.3 it has hundreds of new features over 10.1.2.
I created a struts action in 10.1.3 copied your code into it and compiled without any problems.
