Hi ,

String arr[ ];
request.setParameter("InvalidMeetingDates", arr);

do this in servlet and get the attribute in jsp for iterating by

String[] str = (String[])request.getAttribute("InvalidMeetingDates");

thanks and regards,

Hi,
Thanks for your reply,
Mean now i can pass the array elements from servlet to jsp,
but actually i am using java class, in it i am having array.
Now again the question will arise that how i will pass this array from java class to servlet.
If this problem will be solved then my whole problem will get solved.
Please reply.
Thank you once again...

Servlet is like any other Java class. So how can you return an array of instance or local variable from a method ? Isn't that a basic question of general programming ?

[Bennet Xavier]

after populating the values to the array, return the array from the method you use in java class.

as simple as that.

There is no such methiod.

String[] str = (String[])request.getAttribute("InvalidMeetingDates");

That assumes the use of scriptlets which should not longer be sued in JSPs.

Use the JSTL and El instead.

By the way, to set a scoped variable into the request for use on the JSP use request.setAttribute();
