Hi, I am a beginner of Java and Jsp. Could You please tell me, How to convert the below java file into jsp file.

Thanks for responsing.

package parserexamples;

import java.io.File;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.StringReader;
import java.io.Writer;
import java.util.HashMap;
import java.util.Vector;

// JAXP
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.transform.Result;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

// DOM
import org.w3c.dom.Node;
import org.w3c.dom.Element;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.w3c.dom.NamedNodeMap;
import org.xml.sax.InputSource;


public class Check{
public static void printNode(Node node, String indent) {

switch (node.getNodeType()) {
case Node.DOCUMENT_NODE:
NodeList nodes = node.getChildNodes();
if (nodes != null) {
for (int i=0; i<nodes.getLength(); i++) {
printNode(nodes.item(i), "");
}
}
break;

case Node.ELEMENT_NODE:
String name = node.getNodeName();
for (int i=0; i<attributes.getLength(); i++) {
Node current = attributes.item(i);
}





// recurse on each child
NodeList children = node.getChildNodes();
if (children != null) {
for (int i=0; i<children.getLength(); i++) {
printNode(children.item(i), indent + " ");

}
}


break;

case Node.TEXT_NODE:
System.out.println("Node.TEXT_NODE");
break;
}

}

public static void main(String[] args) {

ile xmlFile = new File("C:/Documents and Settings/edward/Desktop/Role.xml");
try {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(false);

DocumentBuilder builder = factory.newDocumentBuilder();
System.out.println();

Document doc = builder.parse(xmlFile);

Node node = doc;
printNode(doc, "");
System.out.println("\n");
} catch (ParserConfigurationException e) {
System.out.println("The underlying parser does not support " +
"the requested features.");
e.printStackTrace();
} catch (FactoryConfigurationError e) {
System.out.println("Error occurred obtaining Document Builder " +
"Factory.");
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}

}

Thanks for responsing.

Why would you do a thing like that?

The file you posted desn't seem to have anything to do with generatng a view.

edward durai,
Javaranch tip:

If you are going to post more than a line or two of your code, wrap that
code in a set of UBB Code tags.
Doing so will help to preserve your code's indenting, making it easier to read.
If it is easier to read, more people will actaully read it and you will
stand a better chance of getting help with your question.
See UseCodeTags for more
help with UBB code tags.

OK, so I ask again. What does this type of processing have to do with JSP?

actually my xml looks like

<fieldid>
<field f_id="0" sortingorder="3"/>
<field f_id="1" sortingorder="1"/>
<field f_id="2" sortingorder="2"/>
</fieldid>

i want to fetch the order only. ok. That's why I am using the above program. And it should work for both ie and firefox.

Thanks

Building an XML document is not view manipulation.
This is not something you would ever want to do in a JSP.

Bear's question was very simple.
Why would you want to convert something like this into a JSP?

Edward, it sounds like you want to read an xml file and display it in the browser.

Is this correct?

If so, a more proper way to do this (and what Bear and Ben are hinting at) is to create a servlet. Especially for the part that reads the xml file.

Is this an academic exercise where you were told to write a JSP?
