Write/Read Array of BeanObjects using XMLEncoder

[kaaj]

Hi,

This is very urgent. I've designed a feedback Bean.

import java.io.Serializable ;

public class FeedbackBean implements Serializable{

private String assetName;
private String comments;
private String reusability;
private String userName;
private String date;

public FeedbackBean() {

}

/**
* @return String
*/
public String getAssetName() {
return assetName;
}

/**
* @param dt string
*/
public void setAssetName(String an) {
assetName = an;
}

/**
* @return String
*/
public String getComments() {
return comments;
}

/**
* @param comment string
*/
public void setComments(String com) {
comments = com;
}

/**
* @return String
*/
public String getReusability() {
return reusability;
}

/**
* @param reuse String
*/
public void setReusability(String reuse) {
reusability = reuse;
}

/**
* @return String
*/
public String getDate() {
return date;
}

/**
* @param dt string
*/
public void setDate(String dt) {
date = dt;
}


/**
* @return String
*/
public String getUserName() {
return userName;
}

/**
* @param name string
*/
public void setUserName(String name) {
userName = name;
}
}


I added these feedback bean objects to the FeedbackCollection object

import java.io.Serializable;
import java.util.Iterator;
import java.util.*;


public class FeedbackCollection implements Serializable {

private List feedbackList = null;

public FeedbackCollection() {
feedbackList = new ArrayList();
}

public void addFeedback(FeedbackBean fb) {
feedbackList.add(fb);
}


public ListIterator getFeedback() {
return feedbackList.listIterator();
}

public FeedbackBean getFeedback(int index) {
return (FeedbackBean)feedbackList.get(index);
}
}


If I write this Feedback Collection Object to xml, will I be able to read/write the individual Feedback Bean objects?

I've attached the piece of code which I tried


import java.io.Serializable ;
import java.io.*;
import java.beans.*;
import java.util.*;

public class FileWriter {

public FileWriter() {}

public void writeTo(String fileName, FeedbackCollection fbc) throws Exception {
if (fileName == null || fileName.equals("")) {
throw new FileNotFoundException("Invalid File Name");
}

File f = new File(fileName);
if (f.exists()) {

FileInputStream in = new FileInputStream(fileName);
ObjectInputStream s = new ObjectInputStream(in);
//FeedbackCollection decode = (FeedbackCollection) s.readObject();

//ListIterator it = decode.getFeedback();

while (it.hasNext()) {
// Get element
FeedbackBean temp = (FeedbackBean) it.next();
System.out.println(temp.getAssetName());
System.out.println(temp.getComments());
System.out.println(temp.getReusability());
System.out.println(temp.getUserName());
System.out.println(temp.getDate());
}
}
else
{
FileOutputStream out = new FileOutputStream(fileName);
ObjectOutputStream s = new ObjectOutputStream(out);
s.writeObject(fbc);
s.flush();
}
}

public static void main(String args[]) throws Exception {
FeedbackBean fb1 = new FeedbackBean();
fb1.setAssetName("MyAsset");
fb1.setComments("Excellent");
fb1.setReusability("Excellent");
fb1.setUserName("serName");
fb1.setDate("date");

/*FeedbackBean fb2 = new FeedbackBean();
fb2.setAssetName("Asset2");
fb2.setComments("Excell");
fb2.setReusability("Exc");
fb2.setUserName("ser");
fb2.setDate("today");

FeedbackCollection collection = new FeedbackCollection();
collection.addFeedback(fb1);
collection.addFeedback(fb2);*/

FileWriter writer = new FileWriter();
writer.writeTo("temp.obj", fb1);
}

}

This is really urgent..

Any body there to help me out...

I solved the reading/writing part to the xml.

But is there a way to make the xml file - well formatted.
