I place jdom.jar in tomcat/lib and update the tomcat.bat file

if exist "%TOMCAT_HOME%\lib\jdom.jar" set CP=%CP%;%TOMCAT_HOME%\lib\jdom.jar

<%String symbol=request.getParameter("symbol");%>

<%String name=request.getParameter("name");%>

<%String price=request.getParameter("price");%>

<%addBean.adding(symbol,name,price);%>

<%=symbol%>

</body>

</html>

My addelements.java :

package dombean;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import org.jdom.Document;

import org.jdom.Element;

import org.jdom.input.DOMBuilder;

import org.jdom.output.XMLOutputter;

public class addelements{

public void adding(String symbol,String name,String price)

{

String Symbol=symbol;

String Name=name;

String Price=price;

try

{

DOMBuilder builder=new DOMBuilder("org.jdom.adapters.XercesDOMAdapter");

Document doc=builder.build(new FileInputStream("c:/xml/stocks.xml"));

Element root=doc.getRootElement();

Element parent=new Element("stock");

Element child1=new Element("symbol").setText(symbol);

Element child2=new Element("name").setText(name);

Element child3=new Element("price").setText(price);

root.addContent(parent);

parent.addContent(child1);

parent.addContent(child2);

parent.addContent(child3);

XMLOutputter fmt=new XMLOutputter();

fmt.output(doc,new FileOutputStream("stocks.xml"));

}

e.printStackTrace();

}

}
