Hi guys ,
I have a problem trying to process a form which is inside a jsp page under WEB-INF.
My environment: NetBeans 6.9, GlassFish 3.1, Struts 1.3.8
I took this example by reference:
http://netbeans.org/kb/docs/web/quickstart-webapps-struts.html
In this example there is a struts <html:form> login form inside a jsp, outside WEB-INF directory, so the jsp can be directly accessed from the browser;
In my application I need the jsp that contains the form, to be inside web-inf directory, but if I make the changes in this way I get the following scenario:
After I do everything and I make the deployment, I do the following:
- input the address: http://localhost:8080/MyStrutsApp/loginn and the login form appears
- then I fill in some input, I press Login and I get a 404 Error
Can you please have a look on my code and give some ideas?
