Generating Xml file in run-time

[Ashwin Sridhar]

HI,

I am generating the xml file at runtime and when i try to run the application, i find that xml file is not in the classpath. How to solve this issue.

import java.io.File;
import java.io.FileOutputStream;

import org.apache.xerces.dom.DocumentImpl;
import org.apache.xml.serialize.OutputFormat;
import org.apache.xml.serialize.Serializer;
import org.apache.xml.serialize.XMLSerializer;
import org.w3c.dom.*;

import Application.SpringContextApplication;


public class InitialClass {
 public static void main(String[] args){
	 Element ele = null;
	 Element root = null;
	 Node node = null;
	 Document doc = new DocumentImpl();
	 root = doc.createElement("beans");
	 root.setAttribute("xmlns","http://www.springframework.org/schema/beans");
	 root.setAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
	 root.setAttribute("xmlns:context", "http://www.springframework.org/schema/context");
	 root.setAttribute("xsi:schemaLocation", "http://www.springframework.org/schema/beans "+
                           "http://www.springframework.org/schema/beans/spring-beans-2.5.xsd "+
                           "http://www.springframework.org/schema/context "+
						   "http://www.springframework.org/schema/context/spring-context-3.0.xsd");
	 node = doc.createTextNode(null);
	 ele = doc.createElementNS(null, "bean");
	 ele.setAttributeNS(null, "id", "myDaoBeanId");
	 ele.setAttributeNS(null, "class","DaoImpl.myDaoImpl");
     ele.appendChild(node);
     root.appendChild(ele);
     doc.appendChild(root);
     try{
    	 File file = new File("src/test.xml");
    	 if (!file.createNewFile()){
    		 file.delete();
    	     System.out.println("Deleted file.."); 
    	 }
    	 FileOutputStream myXmlFile = new FileOutputStream(file);
    	 
    	 OutputFormat of = new OutputFormat("XML", "UTF-8", true);
    	 of.setIndenting(true);
    	 
    	 XMLSerializer s = new XMLSerializer(myXmlFile, of);
    	 s.asDOMSerializer();
    	 s.serialize(doc.getDocumentElement());
    	 myXmlFile.flush();
    	 myXmlFile.close();
    	 System.out.println("completed creating xml file");
     }catch(Exception e){
    	 e.printStackTrace();
     }
   SpringContextApplication.Call();
      
 }
}

The bean wiring is all working fine. I have this issue of xml file not being found in the classpath. Any suggestions

When i read the XML from FileSystem, it is working fine.
But when i read from Classpath, it doesn't find the file in the classpath

This was resolved by pointing the run-time Xml file directly to the build path.

I was pondering upon generating the xml file at runtime for some time. Your code seems useful. Thanks.
