While it is wonderful that you have discovered the magically code tags, please consider if it is the right time to use them. Code tags should only go round code. Note used to make your posts "stand out", or used to quote other people. Just code.
As to your question, what have you tried, what are you stuck on?

hi
u need a parser or validate the xml file for to read the xml file from java coding u need for this
xml4j.jar u can download this file from here
http://www.alphaworks.ibm.com/tech/xml4j
or we can use the SAX(simple API for XML)
some sample applications for this

How I can create a XML file from java Aplication

How I can create a XML file from java Aplication
whith have a the following structure
<users>
<user>
<login>anyName</login>
<password>xxxx</password>
</user>
</users>
the password label must be encripted
accept any suggestion

Let us assume you have all the data from the jsp form in an java bean object..
Now you want a xml file. This can be acheived in 2 ways
1. Write it into a file using java.io classes. Say you have a class with name
write("<name>"+obj.getName+</name>);
bingo you have a flat file with the xml
2. Use data binding to do the trick
will recommend JiBx and Castor for the 2nd option

Creating XML file from Java Bean

Hi
Are there any standard methods in Java 1.5 to create XML file from java bean,

But i would like to know if there is any thing in java core classes,

How to modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

Create XML file from java

Hi all i am working to create a XML file using java can any one show me some sample code how to do so

All I suggested was to insert a single line ("X.serialize(root);") into your code. Anyway, here's a ready-to-compile source code based on yours. This code utilizes the Xerces-J class library.import java.io.File;
import java.io.FileWriter;
import org.apache.xerces.dom.DocumentImpl;
import org.apache.xml.serialize.OutputFormat;
import org.apache.xml.serialize.XMLSerializer;
import org.w3c.dom.Element;
public class Test {
public static void main(String[] arguments) {
    FileWriter out;
    DocumentImpl d;
    Element root;
    XMLSerializer X;
    try {
      System.out.println(" creatin ");
      File fos = new File("xsr.xml");
      out = new FileWriter("xsr.xml");
      System.out.println("created File .." + fos.getName());
      out.flush();
      d = new DocumentImpl();
      System.out.println("create root");
      root = d.createElement("abc");
      System.out.println("creating element");
      d.insertBefore(root, null);
      //out.write(d.createAttribute(""));
      OutputFormat o = new OutputFormat(d);
      System.out.println("Output format...");
      o.setIndent(5);
      o.setIndenting(true);
      o.setDoctype("lab1.dtd", "lab1.dtd");
      o.setDoctype("name of dtd file", "name of dtd file");
      X = new XMLSerializer(o);
      X.setOutputCharStream(out);
      X.serialize(root);
      out.flush();
      out.close();
    catch (Exception e1){

Reference faces-config.xml file from java code.

For example:
Navigation Rule:

<navigation-case>
<from-outcome>pricingEngine</from-outcome>
<to-view-id>/faces/template/t_pricing_engine.jsf</to-view-id>
<redirect/>
</navigation-case>
</navigation-rule>
I would like do some sort of lookup by 'pricingEngine' and get '/faces/template/t_pricing_engine.jsf' back.
Any ideas?

Creating an xml file from java.

I trying to create an xml file using a java program. I just wondering what is the best way to go about it and what should i use jdom ,xerces sax etc.

Use JAXP+SAX.
Here an example:import java.io.*;
// SAX classes.
import org.xml.sax.*;
import org.xml.sax.helpers.*;
//JAXP 1.1
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.sax.*;
// PrintWriter from a Servlet
PrintWriter out = response.getWriter();
StreamResult streamResult = new StreamResult(out);
SAXTransformerFactory tf = (SAXTransformerFactory) SAXTransformerFactory.newInstance();
// SAX2.0 ContentHandler.
TransformerHandler hd = tf.newTransformerHandler();
Transformer serializer = hd.getTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING,"ISO-8859-1");
serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"users.dtd");
serializer.setOutputProperty(OutputKeys.INDENT,"yes");
hd.setResult(streamResult);
hd.startDocument();
AttributesImpl atts = new AttributesImpl();
// USERS tag.
hd.startElement("","","USERS",atts);
// USER tags.
String[] id = {"PWD122","MX787","A4Q45"};
String[] type = {"customer","manager","employee"};
String[] desc = {"Tim@Home","Jack&Moud","John D'o�"};
for (int i=0;i<id.length;i++)
atts.clear();
atts.addAttribute("","","ID","CDATA",id);
atts.addAttribute("","","TYPE","CDATA",type[i]);
hd.startElement("","","USER",atts);
hd.characters(desc[i].toCharArray(),0,desc[i].length());
hd.endElement("","","USER");
hd.endElement("","","USERS");
hd.endDocument();
[i]This xml generation program might be the best solution because it uses JAXP 1.1 so it will work under JDK 1.4 or JDK 1.2/1.3 with XALAN2 library (or any XML library JAXP 1.1 compliant). It's also memory-friendly because it doesn't need DOM.
See http://www.javazoom.net/services/newsletter/xmlgeneration.html
Hope That Helps

I didn't quite get what the problem is but if the the desired file is in custom directory why don't you just use absolute path to reference it?
Like: "/home/my/OSconfig/MConfig.xml"

How to Read and Generate XML file from java code.

hi guys,
how to read the xml file (Condition :we know only DTD or Shema only).
How to Generate the new xml file ?(using Shema )
And one more how directly Generate the xml from DB?
Pleas with code or any URL

Using XMLbeans you can generate Java objects from an XSD schema (perhaps DTDs aswell)
Then you can create an instance of the Document object and ask it to write itself.
This will create an XML document complient to the schema.
XMLBeans generates a "type" safe DOM where you can only ever have a structure compilent to you schema.
