Construct XML files in Java

Hi,
Can you any give me some third party libraries widely used to create XML file out of trading information ?
Thanks

XML handling has been available in core Java since v1.4.
But if you stick to a third party library, JDOM is fine.
private static String transform( org.w3c.dom.Document doc ) throws Exception
    javax.xml.transform.TransformerFactory      tf = javax.xml.transform.TransformerFactory.newInstance();
    javax.xml.transform.Transformer             t = tf.newTransformer();
    javax.xml.transform.Source                  source = new javax.xml.transform.dom.DOMSource( doc );
    java.io.StringWriter                        sw = new java.io.StringWriter();
    javax.xml.transform.Result                  result = new javax.xml.transform.stream.StreamResult( sw );
    t.setOutputProperty( javax.xml.transform.OutputKeys.ENCODING, ENCODING );
    if ( OMIT_XML_DECLARATION )
      t.setOutputProperty( javax.xml.transform.OutputKeys.OMIT_XML_DECLARATION, "yes" );
    t.transform( source, result );
    String      ret = sw.toString();
    return ret;
}

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

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){
      e1.printStackTrace();

But i would like to know if there is any thing in java core classes,
I have seen XMLEncoder, but this is not what i want.
Any ideas

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

How to write as XML file using java 1.5

hi all,
i am trying to create an XML file using java 1.5. I took a XML creating java file which was working with java 1.4 and ported same file into java 1.5 with changes according to the SAX and DOM implmentation in java 1.5 and tried to compile. But while writing as a file it throws error "cannot find the symbol."
can any body help me out to solve this issue.......
thankx in advance
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.w3c.dom.NamedNodeMap;
import org.xml.sax.SAXException;

import org.xml.sax.helpers.ParserFactory;
import java.io.*;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
               dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document xmlDoc = db.newDocument();
// this creates the xml document ref
// parent node reference
Element rootnd = (Element) xmlDoc.createElement("ALL_TABLES");
// root node
xmlDoc.appendChild(rootnd);
Element rownd = (Element) xmlDoc.createElement("ROW");
rootnd.appendChild(rownd);
Element statusnd = (Element) xmlDoc.createElement("FILE_STATUS");
rownd.appendChild(statusnd);
statusnd.appendChild(xmlDoc.createTextNode("Y")
FileOutputStream outpt = new FileOutputStream(outdir + "//forbranch.xml");
Writer outf = new OutputStreamWriter(outpt, "UTF-8");
//error is occuring here Since write method is not available in the Document class
xmlDoc.write(outf);
outf.flush();

Hi,
when I look in the JDK1.4.2 specification I don't see any write method in the Document interface.
However, your solution is the Transformer class. There you transform your DOM tree into any output you need. Your code sould look something like this:     TransformerFactory tf = TransformerFactory.newInstance();
     // set all necessary features for your transformer -> see OutputKeys
     Transformer t = tf.newTransformer();
     t.transform(new DOMSource(xmlDoc), new StreamResult(file));Then you have your XML file stored in the file system.
Hope it helps.

Accessing XML files through java

Can any one explain me the easiest way of accessing XML files from Java.

Hi,
If you want to only access the XML file, use the SAX parser It will be very easy to handle and identify the element and value.
else if u want to change the XML value also, then better go with DOM, Which has very good flexiblity.
use according to the need, let me know if any help is required......

The nicest way to generate xml-files by Java???

I have to generate huge and quite complex xml files by Java. I have to fetch the data from a Oracle database. What I really don't know is a proper and reliable way to this? I could of course create a String and concatenate all the tags, attributes and data but it doesn't feel right. I guess this is a quite common task and there are many established ways to this by Java. My question is what is the best way to this? What is your suggestion?
Thank you for any clues...

Hi,
Since you have access to the database, I think one of the best way is to create stored procedures that will generate those files for you (using SQL/XML functions preferably) and return the content to the Java caller.

Do i required to generate XML file for JAVA upgrade.

Dear frnds,
I am in process of upgrading EP 6.0 to EP 7.0 EHP1 for SR1.
I am following document Upgrade Guide SAP NetWeaver 7.0 Java Including Enhancement Package 1
As of media list guide i have selected .
51036889_1/2 for UPG MASTER BS7 SR1
51037093_1,2,3 for NW 7.0 EHP1 SR1 java SW components 1/2
51036767_2 for BS7 UC kernel 7.01 AIX 64 bit.
Well, i have a query here when i am doing upgrade on ABAP stack ECC 5.0 to ECC 6.0 EHP4 SR1 i alowed to select required compoenets , which eventually will generate mea XML file in Solution manager system.
But, When i have planned to UPGRADE only JAVA Stack for EP 6.0 to EP 7.0 EHP1 SR1. When i selected my system in Solution manager i am not getting option for UPGRADE.
If it is so how about my XML file during JAVA upgrade is not mandatory or not .. Please advice me on this.
regards,
rahul

Hi Rahul,
Yes, for Java Upgrade to EHP1 you need xml file. Normally you should be able to download xml file from solution manager from MOPZ.
If you are not able to download it from solman then you can also download the xml file from service market place and this is only for EHP1. Follow below procedure to download xml file from SMP for EHP1:
Go to https://websmp205.sap-ag.de/sp-stacks
Click on SP Stack download.
Select SP Stack Netweaver 7.0 (New window will open)
Then on New Window Select Source Stack, Target Stack and usgae type. Then Click Next.
On Next screen Select Kernel and IGS. Then Go Next.
On that screen you will get a option to Save as File. Then save as xml.
This is the xml file that you can use in upgrade.
For EHP4 you cannot download it from service market place.
Thanks
Sunny
