Struts Question:Using session object to store info

http://www.mywebsite.com/process.jsp...1&para2=value2

When a user types in the above URL in a browser, I am trying to get para1 value and para2
value from the URL query string and store it in session.

Here is the method I tried!

In the reset() method of the ProcessForm class, I first got the values of para1 and para2
using
String Parm1 = session.getParameter(\"para1\");
String Parm2 = session.getParameter(\"para2\");

and then tried to write to the session using

request.getSession().setAttribute(\"Parm1\",Parm1);
request.getSession().setAttribute(\"Parm2\",Parm2);

So, all the above code is in the reset() method of the ProcessForm class.

When I go to the next page, say process2.jsp, and retrieve session information from
Process2Form\'s reset() method, I am getting \"null\" as the value for Parm1 and Parm2.

Am I doing something wrong or is there another way to do this?

Currently, in the ActionMappings, all Form beans have scope set to \"request\". I tried to change
this to \"session\", but to no use!

Any help would be appreciated!

Praveen,

When you use request.getSession().setAttribute(\"Parm1\",Parm1);
it creates new session and sets the attribute.

So while retreiving session information from Process2Form\'s reset() method,
try like this:
request.getSession(false).getAttribute() instead of
request.getSession().getAttribute() , so that it will use the existing session.

If you didnot provide false parameter it will creates new session. So u r unable to find the data in the new session.

Hope this helps.

Cool!

Another question.

There are three pages -

InitialPage.jsp
CollectInfo.jsp
FinalPage.jsp

If a user comes to FinalPage.jsp directly, he/she should be routed/redirected to InitialPage.jsp

How do I implement this?

You can use Request Dispatcher methods or jsp: forward or html meta tags.

In your third jsp page
<META HTTP-EQUIV=\"Refresh\" CONTENT=\"0; URL=page1.jsp\">

When you redirect or submit to a page, that URLwill show up on the browser\'s address bar and history and will be what gets loaded when the browser\'s refresh or back buttons are used. When you forward to a page, it will show up neither in the address bar nor in the history, so the browser\'s refresh button would load the previous page.

For example, if 1.jsp does a jsp:forward to 2.jsp. If you type in \"1.jsp\" in the browser\'s address bar, you will see 1.jsp there, but the browser will display the results of 2.jsp.

If 1.jsp does a response.sendRedirect() to 2.jsp and you type in \"1.jsp\" in the address bar, you will see \"2.jsp\" in the address bar and the browser will display the results of 2.jsp.
