I have a JSP file that refers to CSS. My JSP has a form that redirects to the servlet .
The servlet does some heavy database queries etc.
Then the data is shown on the servlet page
However since the servlet does not have any formatting , the data is displayed without any formatting . How can I get the formatting from that jsp file and apply it to servlet .
I could use
out.println(".. )
but this is not convinient.
Here's one way to do this:
1) put the content you want to show in a request scope. You can do this using setAttribute() of request. Eg, request.setAttribute("mycontent", <your actual content>)
2) "your actual content" can be any data structure. Choose one that fits your needs.
3) In your second JSP, use this data structure. YOu can do, request.getAttribute("mycontent") (dont forget the cast. This returns Object)
4) You can apply whatever CSS you have to this content.
Cheers!
Create another JSP page to which this servlet dispatches response, add your CSS there, use the JSP to render pages the way you want.
I suggest you go through MVC pattern for creating your web application.
You shouldn't just have the servlet forward to the JSP. Since the last action known to the browser is the post from the form, a refresh of the page to which you were forwarded causes another post to happen. You probably don't want that.
The correct approach is to post to a servlet which performs the update logic. The servlet then does a send-redirect (status 302?) back to the browser with the url of the follow-on page. The browser then does a get for that page and a subsequent refresh will work correctly.
