Hi Amit,
Here the code example:

import java.sql.*;
import java.text.*;
import java.util.*;
import org.jdom.*;
import org.jdom.output.*;

public class WebStylesCreateXML {

  private ResultSet rs = null;

      while (rs.next()) {

        cntr++;

      }  // end for loop of ResultSet

      xmlOut.output(doc, pw);
      pw.flush();
      pw.close();

    } catch(Exception ioE) {
      ioE.printStackTrace();
    }
  }

  public static void main(String[] arg) {
    WebStylesCreateXML process = new WebStylesCreateXML();
  }
}

Hope this help,
Alex

Hi Aaron,

I am using Java(JT400.jar/JDBC-ODBC) to extract the info from DB2
database, once the databse info is available in the ResultSet it should
be able to write an in-memory DOM document Object then this information
should be written to an XML file. So thats the idea.

Any suggestions/questions??

Amit.

What languages are you familiar with?  Or rather, what language do you
want it in?

How do you want to make the XML available? Put it into the IFS, via CGI
over HTTP, or something else?

There are many ways to skin this cat.  Maybe if you could give us some
more information as to what you are trying to accomplish. . .

Hi All,

I need help with accessing data from AS400 database DB2. We have some
database files in AS400 (DB2) which has to be retrieved/accessed and
that data should be available in an XML file. Please send me some sample
code of XML to do this, if available.

Thanks a lot for your help,

Amit.
