How to load a jsp without refreshing.

[gurusamy sengodan]

Hi there,

It is very urgent. i hope you people will help me to come out from this problem.

Consider i am having one jsp. Name is A.jsp.
In A.jsp i have used grid to select some records.
I have written one java script function to call one servlet.( Name is LLReportServlet.java)

In servlet i have to redirect to the same jsp ( i mean A.jsp)
While re directing to that jsp it got refreshed. But It should not happen.
Because i have to retain the grid values ( Selected values) once it come back to that Jsp.

Could you please tell me how to do this?


Thanks
Gurusamy

Please EaseUp.

You can either submit all the values to the servlet, so that the JSP page can be delivered with them when it is reloaded, or use an AJAX mechanism to call the servlet.

I think the below code works fine depending on some requirements :

<form action="LLReportServlet" method="post">
<input type="text" name="userName" value="${param.userName}"/>
</form>

If your servlet redirects the user to A.jsp page through RequestDispatcher.forward method the approach above works fine.

You might also split your jsp in two. Read the values from the form on one part and change the url location of an IFrame to load the other part. The part with the detailed data refreshes, but the part with the grid does not.

AJAX is cooler by far, but a bit tricky and is best done with some third party javascript libraries which are hard to get permission for in my shop.
