java.lang.string

when i execdute my jsp the below exxception is comming
Ljava.lang.String;@156782
what may be the problem
please send me

Doesn't look like exception.
I gues you trying to print array. Could you post code?

Iam sending the code.please see and tell me what may be the exception

The exception must have appeared somewhere - in logs or in server console.
I suspect this code:

This is a guaranteed error, but I wonder why you did not get a compile error when the JSP was compiled. You don't even need that cast since getParameterValues(...) already returns a String[].

sorry i have given there stringarray only not string.
i have forgotten to modify and posted

Then please do search logs and traces for exception informations, also you can add System.out.println(...) statements in your code to locate the code that generates the exception. I doubt we can help you without additional information.

It seems you got answer in your other thread. Posting several threads for the same thing is bad practice because you waste other people's time.
Please take the time to read the CarefullyChooseOneForum of 'how to ask'.

As I have said in another post by you for the same issue, you do not get an Exception. You have printed out the String[].

out.println(rootvalue+checkedValues);

This prints the address of the String[] "checkedValues" and not the elements.

Please do not cross-post the same question in in the same or across multiple forums. It wastes people's time when multiple redundant conversations take place.
