Encoding and Decoding

[francis varkey]

Respected Sirs,
In my application I have using an ajax. In url I am passing some values containg "&" .So I am encoding it using 'escape()' function of javascript.
Later in Servlet I am decoding it using "java.net.URLDecoder.decode(String,"UTF-8")". But this decode() method is not working.

Regards Francis

That doesn't give us a whole lot to work with.
What string are you decoding?
What is being returned from the decode method?
What were you expecting it to return?

The more specific you can make your question, the easier it will be for us to answer.

Client side code --- javascript
--------------------------------------

function test()
{
var name="Test & Test";
var Id="11";
var url="<%=appPath%>/TestAction.do?ID="+Id+"&name="+escape(name);
 
req=null;
if (window.XMLHttpRequest)
{
req = new XMLHttpRequest();
 
}
else if (window.ActiveXObject)
{
req = new ActiveXObject("Microsoft.XMLHTTP");
}
 
req.open("GET", url);
req.onreadystatechange = callback;
req.send(null);
}
 

Here I am encoding "srcName" using escape() function.
----------------------------------------------------------------------

Server side code ---Java
----------------------------

public ActionForward perform(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException
{
String name=request.getParameter("name");
name=name==null?"":java.net.URLDecoder.decode(name,"UTF-8").trim();
System.out.println(name);
}

I am expecting the out put is Test & Test
But I get
Test & Test
That is decoding is not done.

In the above two posts ,the last line is

I am expecting the out put is Test & Test
But I get
Test & amp; Test (here I put a space after & )
That is decoding is not done.

If I were debugging this, the first thing I would do is add a print statement before decoding on the Java side to see exactly what I'm decoding.

public ActionForward perform(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws IOException, ServletException
{
String name=request.getParameter("name");
[B]System.out.println(name);[/B]
name=name==null?"":java.net.URLDecoder.decode(name,"UTF-8").trim();
System.out.println(name);
}

I would also use an alert to see exactly what was returned from the escape function:

 
function test()
{
var name="Test & Test";
var Id="11";
var url="<%=appPath%>/TestAction.do?ID="+Id+"&name="+escape(name);
[B]alert(url);[/B]
