I have a small sample application which has 2 jsps and an action form
an action class and the config files. In the input jsp page which is
"Register.jsp" I have fields for first name, last name and alias. In
the output jsp which is "thankyou.jsp" I'm printing the firstname(using
bean:write) taken as input from "register.jsp"
I'm getting the error:
"Error 500: Cannot find bean registrationFormBean in any scope"

Your form is in request scope. You are redirecting to thankyou.jsp, which
means the browser will make a new request-- and the form bean won't be in
it.

You could put your form in session scope or forward (instead of redirecting)
to thankyou.jsp.

My files:

struts-config.xml [cut]
<action-mappings>
<action name="registrationFormBean" path="/register" scope="request"
type="com.webagesolutions.struts.actions.Register"
input="register.jsp">
<forward name="success" path="/thankyou.jsp" redirect="true">
</forward>
Click to expand...

scope="request" in action element and redirect="true" in forward element
are the source of problem.
redir
Use scope="session" or redirect="false".

redirect="true" effect is finish service for request by sending
http://java.sun.com/products/servle...tResponse.html#sendRedirect(java.lang.String)
to client, then new request is created (in new request is no form-bean).
In this case scope for form-bean have to be "session".

redirect="false" is translated to
http://java.sun.com/products/servle...ervletRequest, javax.servlet.ServletResponse)
so there is no new request and form-bean will be in scope.
