Hi,

Could you add the code snippet which is used to call the Myjsp from servlet.

Also the action value of the form from Myjsp.

Strange..!

If I have to do a sanity check, like for example lenght check, null check or in this case character check.
I have to post a request from the client to server if its invalid then again post the request with a change.

Will it not be feasible to have basic sanity check on the client side and have a pure business check validation at the server side.

Hi,

1. You can do the validation in the client side.
2. You can do the validation(business) in the server side within servlet

hi,

I think that would not happen.

When you click back and perform operation which required login or session and if you remove session for application then it's always redirect login page...

Yes you are right when any operation is done on the previous page when already session is invalidated.

But if you see the below comment; Sudhakar Kumar wants to know why when browser back is selected he is able to see the previous screen.
If he has set not to cache.

But in all pages I maintian No cache, then no point to maintain the cache..

So When user selects browser back there is GET request to the server.

Hi,

Try changing the url-pattern like below :

<filter-mapping> <filter-name>authentication-filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

When you select browser back then there will be a GET request invoked to the orgin server with the URL used previusuly.
If you have a workflow in place then you get everything right or the previous page will not be displayed.

Bill,

Is it feasible to store user information within cookie?

With your comment its understood that you are invalidating the session.
When you say , you selected previous page, did you selected Browser back?

If this is the case its Browser cache which is getting displayed.

How you are saying that session is still keeping?

Yes we can send sendredirect.

But what do you mean by continously?

What is the Application Server you are using?

In tomcat we have an option to share the context between the applications
if both applications reside in a same server.

Good.

But your earlier attachment wrt the calci.java says a package definition : classes.

This time I believe you have removed that.

If you could see in the error stack trace, its saying java.lang.NoClassDefFoundError: calci (wrong name: classes/calci)

And if you see web.xml you have defined the servlet class as :
<servlet-class>calci</servlet-class>

Which should be
<servlet-class>classes.calci</servlet-class>

Besides the class name should start with a Capital letter.

Rather it should be pageContext.forward("/resource.jsp");

Is there any difference in what i specified and what you suggested ??



And i am using this inside the servlet , and not in jsp

Difference is highlighted in bold.

And the other difference is mentioned by Balu above.

Hi,

PageContext.forward("/resource.jsp");

Have a look of PageContext API.

We dont have any static method forward within PageContext Class, so the error.

Rather it should be pageContext.forward("/resource.jsp");
Assuming you are using within a JSP.

Divya,

I believe you submitting the HTML form to a Servlet.
Then retrieve the value from request and set it to the Java class.
