Protected Method access

[Rohan Kalbhor]

Hi guys,

I have a class in a.jar which has a method of "protected void a()" type.
a.jar is a signed jar file.

I have another b.jar file which wants to access the method a()
but at the present it is not able to do so...i have tried all possible solutions
b.jar is unsigned.

now this is the last option i am not sure about so...i need help from you guys.

Does signing of jar makes a difference in acces of protected methods,and it is not possible to access it from an unsigned jar?

[Jesper de Jong]

The 'protected' access specifier does not have anything to do with whether your JAR files are signed or not; signing or not signing a JAR file does not change the meaning of 'protected'.

A protected class member is accessible in the class itself, in subclasses of that class and in classes that are in the same package as the class.

What is the exact error message you are getting?

Why not simply extend the class in A.jar ?

protected methods are available to subclasses.

Hi jesper,
I am getting no errors and no excpetion....

I have extended the mother class.Event the public methods are getting accesed.Only the protected methods are not getting accessed.I can understand that through the logs i get.

This Topicis going on with refernce to the same problem

[Yelamuri Chandu]

From your ref. link doent talk about the jave access modifier "protected"

That is different and this is different.

I suggest that you post the code for the superclass and the subclass.

superclass

  
package com.a.b.c.d;
public abstract class CTILightAdaptor 
{
  protected void setNewCallID(String aCallID)
    {
        mNewCallID = aCallID;
    }
}
  

subclass

  
package com.a.b.m;
public class myclass extends CTILightAdaptor
{
public void setJCLI(String cid) throws Exception
{
        
super.setNewCallID(cid);
        
        }
}

i am invoking setJCLI from another class...but setNewCallID of CTILightAdaptor is not getting invoked..!!

[Roger Chung-Wee]

A few things I can think of.

1. You do not need to use super as the subclass has access by inheritance to all non-final protected methods in the superclass.

2. Are you sure that the subclass is extending the correct version of CTILightAdaptor?

3. Why do you think that setNewCallID is not being invoked. Have you added logging to this method to check for this?
