Using JSP / Java to write/create an xml file

I have been looking around the internet and in my books and I cannot find a good example of JAVA/JSP writing an XML file. I already have a recursive method that will generate the xml .. what's missing in my code now is how am i goin to append or write that xml string into an existing file..
suppose i have this xml string
String xmlString = "<?xml version="1.0"?><txn><test>this is just a test</test></txn>";
FileOutputStream fos = new FileOutPutStream(C://files/sample.xml);
now , how i will write the xmlString into sample.xml file...
Any suggestions/ ideas/ tutorial links would be deeply appreciated.. thx!

never mind.. my code is workin now..

Do all JSP/Java bean webapps need an xml file?

Hi all,
I have a jsp/ java bean webb application. This is being run on Resin at
Lunarpages.
The site has been shut down due to 'class-loader' not found. I was told it
was causing problems for other java users on the server.
I realise this is limited information but any insight would be welcome.
This is our first JSP / java bean web app.
Also if anyone could tell me briefly the purpose of an xml document in a JSP/Java bean webapplication I would greatly appreciate it.
Thanks in advance
Regards
Jim

Hi there,
Thanks for the reply.
Our application allows people to purchase wedding pictures online. It ran locally on resin we then had to change all the relative file paths in order to deploy it on lunarpages.
Lunarpages use resin also.
We had the application tested and working on Lunarpages for the last week .This morning they sent us a message saying they had shut our JSP pages down as our application was causing problems for other java users. errant code unknown element ' class-loader' .
Not too much help from lunarpages...
thanks

HO w to use SAX parser to create an XML file on the fly

Hi All,
Currently I am using the DOM parser to create an XML file from a text file. But as the DOM takes much memory and inefficient, I need to convert the DOM translator to SAX translator. Can I do that ?? If YES then how to go about that and if NO then what may be the workaround for that.
Please help me out
Thanx in advance
kaushik

Incidentally, look at this thread:
http://forum.java.sun.com/thread.jsp?forum=34&thread=252415
It has an example of how to transform an XML file via XSLT. If you change this to use the zero-argument form of newTransformer, it will apply the "identity transformation" to your input, thus outputting your XML in valid form. Now you just need to figure out how to provide SAX input to this, and the JAXP download includes an example of that.

How to create two level dynamic list using JSP , Java Script and Oracle

I am new in JSP. And i am facing problem in creating two level dynamic list using JSP ,Java Script where the listdata will come from Oracle 10g express edition database. Is there any easy way in JSP that is available on in ASP.NET.
Plz response with details.

1) Learn JDBC API [http://java.sun.com/docs/books/tutorial/jdbc/index.html].
2) Create DAO class which contains JDBC code and do all SQL queries and returns or takes ID's or DTO objects.
3) Learn Servlet API [http://java.sun.com/javaee/5/docs/tutorial/doc/].
4) Create Servlet class which calls the DAO class, gets the list of DTO's as result, puts it as a request attribute and forwards the request to a JSP page.
5) Learn JSP and JSTL [http://java.sun.com/javaee/5/docs/tutorial/doc/]. Also learn HTML if you even don't know it.
6) Create JSP page which uses the JSTL c:forEach tag to access the list of DTO's and iterate over it and prints a HTML list out.
You don't need Javascript for this.

Using jsp creating the xml file on the browser

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 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

Create an XML file from Java

I'm a new user of XML. I've a very important question:
Is it possible create an XML file using some java package? If yes what package i must use? JDOM is the right product?
Thanks

Yes, JDOM is the right choice for 99% of your work.
DOM is too difficult to use.
That is the reason why JDOM has been developped.

How do i create and write to an xml file?

I know there are methods to create nodes and such but I am not at all familiar with xml. Isn't an easier way just to use the File class to create the file and use the write method to write to the xml file? Thank you.

Use of Java Code within the generated XML Forms Stylesheets

Hello,
is the use of Java-Code possible with the XSL-Files generated by XML-Forms, as possible in standard XSLs? I know that this would mean a modification.
kind regards,
Marco

Hi Marco,
I "executed" some java code within XSLs file. I have quoted the word executed because I didn't really run java code, but I used a simply trick that I describe you below.
Into your XSLs put an iframe which is hided (it has an height of 0 pixel). As src of the iframe put the address of a portal component which execute your code (in my case calculate some PCD URL of some pages into a defined role). As result of component execution, I use the response.write method in order to execute some jscript code, which is able to interact with the HTML generated by XSLs files, for example in my case response.write put the PCD URL into a drop down list placed into the "edit" form.
This works fine. I don't know if is suitable also for your case, anyway could be a hint, but pay attention to Roland's recommendations.
Ciao
Roberto

SAX: How to create new XML file using SAX parser

Hi,
Please anybody help me to create a XML file using the Packages in the 5.0 pack of java. I have successfully created it reading the tag names and values from database using DOM but can i do this using SAX.
I am successful to read XML using SAX, now i want to create new XML file for some tags and its values using SAX.
How can i do this ?
Sachin Kulkarni

SAX is a parser, not a generator.Well,
you can use it to create an XML file too. And it will take care of proper encoding, thus being much superior to a normal textwriter:
See the following code snippet (out is a OutputStream):
PrintWriter pw = new PrintWriter(out);
      StreamResult streamResult = new StreamResult(pw);
      SAXTransformerFactory tf = (SAXTransformerFactory) TransformerFactory.newInstance();
      //      SAX2.0 ContentHandler.
      TransformerHandler hd = tf.newTransformerHandler();
      Transformer serializer = hd.getTransformer();
      serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");//
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"pdfBookmarks.xsd");
      serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"http://schema.inplus.de/pdf/1.0");
      serializer.setOutputProperty(OutputKeys.METHOD,"xml");
      serializer.setOutputProperty(OutputKeys.INDENT, "yes");
      hd.setResult(streamResult);
      hd.startDocument();
      //Get a processing instruction
      hd.processingInstruction("xml-stylesheet","type=\"text/xsl\" href=\"mystyle.xsl\"");
      AttributesImpl atts = new AttributesImpl();
      atts.addAttribute("", "", "someattribute", "CDATA", "test");
      atts.addAttribute("", "", "moreattributes", "CDATA", "test2");
       hd.startElement("", "", "MyTag", atts);
String curTitle = "Something inside a tag";
          hd.characters(curTitle.toCharArray(), 0, curTitle.length());
    hd.endElement("", "", "MyTag");
      hd.endDocument();
You are responsible for proper nesting. SAX takes care of encoding.
