help with web services. parse xml string with dom parser

Hi, this is my final project. I have generated an xml string, this is my code:

import java.io.StringReader;

import java.io.IOException;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;



import org.w3c.dom.CharacterData;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

import org.w3c.dom.Node;

import org.w3c.dom.NodeList;

import org.xml.sax.InputSource;



<%@ page import="javax.xml.parsers.*" %>

<%@ page import="org.w3c.dom.*" %>

<%@ page import="java.io.*" %>

<%@page import="recipe.*" %>



<html>

<head>

<title>RECIPE</title>

</head>

<body>



<%

// Instantiate the generated Service

   Recipe service = new Recipe();

        

// Get the port using port getter method generated in CalculatorService

   RecipePortType port= service.getRecipePort();

        

// Invoke the remote method

   FilterRequestType req = new FilterRequestType();

   FilterResponseType resp = port.filter(req);

   String xmlResult = resp.getRecipelist();



// Create an instance of the DOM parser and parse the document

   DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

   DocumentBuilder db = dbf.newDocumentBuilder();

   Document doc = db.parse(new InputSource(new StringReader(xmlResult)));



// Begin traversing the document

   traverseTree(doc, out);

%>





<%   .......................................(the rest of the code)

whenever i run it in my browser, there will be error like this:

An error occurred at line: 39 in the jsp file: /assignment2/domrecipe.jsp
InputSource cannot be resolved to a type
36: // Create an instance of the DOM parser and parse the document
37: DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
38: DocumentBuilder db = dbf.newDocumentBuilder();
39: Document doc = db.parse(new InputSource(new StringReader(xmlResult)));
40:
41: // Begin traversing the document
42: traverseTree(doc, out);

and this:

root cause

java.net.MalformedURLException: no protocol: <?xml version="1.0" encoding="UTF-8"?>
(and then the xml string)

so, basically, the xml string has been read, but there are errors in it... can someone help me..
thanks..

Urgent:XML String

Hi,
thanks for replying i have gone through that thread before posting,but i am not getting it.
Is that thread is a service or client as i am seeing jsp tags and also its not returning..

I have gone through some links and this is what i got.Please correct me ....
1. i wrote a method which takes string as a parameter.
2. In the method, i am generating a xml Document and transforming that DOM to string and returning that string.
Is i am folowing the correct way?.
In some articles i came to know that it should returning a document type,so that will as string i correct format(tags).Is it correct...

please suggest me.....
