hi this is mayur,

The concept of generating xml file if same in java. if you wanna use j2me you should do file handling in your code.

Below is code written in jsp, the only thing you need to modify is to replace the file writing command.

int iLf = 10;
char cLf = (char)iLf;
String xmlfile="path to your directroy/Data.xml";
File outputFile = new File(xmlfile);
outputFile.createNewFile();
FileWriter outfile = new FileWriter(outputFile);

outfile.write("<?xml version='1.0' encoding='ISO-8859-1'?>"+cLf);

outfile.write("<Table>"+cLf);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * from users");



while(rs.next())
{

outfile.write("<users>"+cLf);
outfile.write("<cid>" + rs.getString(1) +"</cid>"+cLf);
outfile.write("<cname>" + rs.getString(2) +"</cname>"+cLf);
outfile.write("<username>" + rs.getString(3) +"</username>"+cLf);
outfile.write("<password>" + rs.getString(4) +"</password>"+cLf);
outfile.write("<email>" + rs.getString(5) +"</email>"+cLf);
outfile.write("<cellno>" + rs.getString(6) +"</cellno>"+cLf);
outfile.write("<address>" + rs.getString(7) +"</address>"+cLf);
outfile.write("<city>" + rs.getString(8) +"</city>"+cLf);
outfile.write("<state>" + rs.getString(9) +"</state>"+cLf);
outfile.write("<zip>" + rs.getString(10) +"</zip>"+cLf);
outfile.write("<country>" + rs.getString(11) +"</country>"+cLf);
outfile.write("<question>" + rs.getString(12) +"</question>"+cLf);
outfile.write("<answer>" + rs.getString(13) +"</answer>"+cLf);
outfile.write("</users>"+cLf);

Hi,
there are many api for XML parsing available for J2ME environment - NanoXML, KXML, etc. With NanoXML, you can do this:

kXMLElement element = new kXMLElement();
element.setTagName("root");
element.addProperty("key", "value");

kXMLElement child = new kXMLElement();
child.setTagName("child");
child.setContent("Teste");
element.addChild(child);

kXMLElement child2 = new kXMLElement();
child2.setTagName("child");
child2.setContent("conteudo");
child2.addProperty("propriedade", "valoer");
element.addChild(child2);

You will have:

<root KEY="value">
    <child>Teste</child>
    <child PROPRIEDADE="valoer">conteudo</child>
</root>

Simple, doen't it?

thanks but

that exsamel is for using an existing XML

i am trying to creat a new simpel XML file on my NOKIA 6288

by j2me

i have a problem in saving the

kNanoXML.kXMLElement element = new kNanoXML.kXMLElement();
element.setTagName("root");
element.addProperty("key", "value");

kNanoXML.kXMLElement child = new kNanoXML.kXMLElement();
child.setTagName("child");
child.setContent("Teste");
element.addChild(child);

kNanoXML.kXMLElement child2 = new kNanoXML.kXMLElement();
child2.setTagName("child");
child2.setContent("conteudo");
child2.addProperty("propriedade", "valoer");
element.addChild(child2);

the "element " to XML file

Writer writer=null ;
try
{
writer.write("c:\\aa.xml");
element.write(writer) ;
}
catch (Exception e)
{
System.out.println("problem in writeing XML file ----- " + e.toString());
}

nonworking
it run but ther is not a new file...

Hi
You need to Use File Connection API in J2Me to work with Files.
simple example to write files in J2me

try 
{
  FileConnection fconn = (FileConnection)Connector.open("file:///CFCard/newfile.txt");
  if (!fconn.exists())
    fconn.create();  // create the file if it doesn't exist
  fconn.close();
}
catch (IOException ioe) 
{

[aaaabaaaa]

so how i conect that to the kNanoXML

Lets starts again mate...

Ok,

1) http://www.devx.com/xml/Article/11773/0/page/1

2) Use RMS to store the XML( No Need to save the File over SD)
