URGENT: require help on struts-nested taglib

Can anyone provide me pointers to tutorial (except the API) on using tags of struts-nested taglib.

More specifically, I'm looking for what <nested:root> tag does ?

Can anyone help me out in understanding this jsp code on following points:
1) In the <nested:root> tag what does the attribute "name=message" refer to ?

2) Is "message" some logical name to any other bean class ? If yes, how can I find that class ?

3) Also, what do the attributes in other nested tage mean ?

Hi Dharmendra,

Thanks very much. It does work with your solution.

Any reason(s) for such behavior ?

GET method working but POST method not working

Ulf,

There are no differences in the code except the method names.

When my html request is GET type, I get the values of input fields.
But when request is POST type, I get null values.

Amit : Form uses GET method when call in servlet is to doGet Method
Form uses POST method when call in servlet is to doPost Method

Is this issue anything related with server I'm using?

Pls excuse me for a long post. As becuase there was a bit of confusion in the forum because I'd posted incorrect code earlier, I'm posting both the code - which does not work(i.e., code using POST method) and which works (i.e., code using GET method)

GET method working but POST method not working

I'm using Eclipse 3.3.2 IDE.

The servlet stub code was generated automatically from it. I've just implemented my logic in the doPOST method.

I've tried with request.getParameter() also. But still the POST method gives null values.

GET method working but POST method not working

Hi,

I'm implementing a simple web application.
I've a jsp page. In the FORM tag I've defined action of my servlet class and method as POST.
The form contains two text fields and a submit button.

In my servlet, I'm doing request.getParameter(<<text field name>>

.

If I'm using GET method, I get the values entered in the text fields.
However, if I'm using POST method, I get null values.

Can anyone pls help me out with a solution for same.

Thanks in advance.

I'm using Tomcat5 webserver.

On applying this XSL on the concerned XML, I get properly required transformed XML.
Now, I want a portion of this transformed XML into an XSL variable. This variable should have exact copy of the portion of XML that I require; which means it should include all the tags, values, etc.
The portion that I require to copy in the variable is between the <lif:xmlInput> and </lif:xmlInput> tags.

Pls help me out with the soultion for same. Any pointers shall be highly appreciated.

Thnx in advance.

Problem with read-write methods in Serialization

Hi Chandra,

It works with writeObject() and readObject() methods.

Thanks.

Problem with read-write methods in Serialization

During serialization, if I'm implementing my own writeObject & readObject methods then which method should I use to read a String.

Please view the following code:

/*
* Created on Oct 9, 2007
*
* To change the template for this generated file go to
* Window>Preferences>Java>Code Generation>Code and Comments
*/
package com.scjp;
import java.io.File;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.io.*;
import java.util.*;
/**
* @author lalll
*
* To change the template for this generated type comment go to
* Window>Preferences>Java>Code Generation>Code and Comments
*/
public class FileSerializationTest implements Serializable {
private int anInt;
private String aString;
public static void main(String[] args) {
FileSerializationTest fObj = new FileSerializationTest();
try {
FileOutputStream fos =
new FileOutputStream("C:/ePartner/Lalit1.txt");
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(fObj);
oos.close();
FileInputStream fis = new FileInputStream("C:/ePartner/Lalit1.txt");
ObjectInputStream ois = new ObjectInputStream(fis);
FileSerializationTest fObj1 =
(FileSerializationTest) ois.readObject();
ois.close();
System.out.println(fObj1.anInt + " " + fObj1.aString);
} catch (Exception e) {
e.printStackTrace();
}
}
private void writeObject(ObjectOutputStream oos) {
try {
oos.writeInt(1);
oos.writeChars("Hello World");
} catch (Exception e) {
e.printStackTrace();
}
}
private void readObject(ObjectInputStream ois) {
try {
ois.readInt();
//WHICH METHOD SHOULD I MENTION HERE--------(1)
} catch (Exception e) {
e.printStackTrace();
}
}
}

Here I've written a String using writeChars() methods while serializaing object. But there is no similar method while reading object during de-serialization.

Can anyone help me out in same.

NOTE - I know that we can do same using defaultWriteObject()/defaultReadObject() methods. But I intentionaly want to go this way. Please provide a solution in the same context.
