Question

Capture multiple check box selection JSP Parameters

Answer 1

+2 A:

You're trying to print the whole string array with System.out.println, and so you get that. It's probably working fine.

Try this:

System.out.println("checked boxes:");
for (int i = 0; i < SelectedValues.length; ++i)
  System.out.println("  " + SelectedValues[i]);

Also, I beg you: in your spare time, find out about a modern web framework (there are zillions for Java) and strive to escape from the painful world of coding Java inside JSP files.

Zillions of which at highest five are okay to look at first (JSF, Struts2, Spring MVC, Stripes and Wicket). Don't scare him ;)

I'm a huge Stripes fan but I didn't want to proselytize.

@BalusC - it's "her" LOL@ Pointy - great thanks that helps....i will look at web framework, but I'm not the big web programmer here, just a peon! This does do exactly what I asked for (prints the 0, 1, 2), but what I really need to do is get the date value that is in that Parameter has to pass that into another query...

@Leslie: oh!! I'm extremely sorry that I didn't pay attention to the maiden name you used as nickname. Your new avatar indeed clarifies a lot :)

Well you're just setting the "value" attribute of each checkbox to "i", not the date.

Pointy 2010-03-11 18:04:18

So I would need to make the value attribute the termDate instead? Why yes! that's exactly what I need to do! Thanks!

Leslie 2010-03-11 18:05:12

@BalusC - no worries! Happens all the time (usually on sites that don't have my picture though!)

Answer 2

A:

You're just facing the default value of Object#toString().

Either just loop over it and print each item, or use Arrays#toString(). Here's an SSCCE:

package com.stackoverflow.q2426380;

import java.util.Arrays;

public class Test {

    public static void main(String... args) {
        String[] array = {"foo", "bar" , "waa"};
        System.out.println(array); // [Ljava.lang.String;@addbf1

        String arrayAsString = Arrays.toString(array);
        System.out.println(arrayAsString); // [foo, bar, waa]
    }

}

That said, this problem has actually nothing to do with JSP. It's just a view technology. The problem is rather in the basic Java code --which you wrote at the wrong place, in a JSP file instead of a Java class. I strongly agree with the comments that writing raw Java code in JSP files is a bad practice. Start learning Servlets.
