I searched this in the forum, but couldn't find answer to this, so I am posting it here.

I tried to call private methods outside the class using the Reflection API. Is it not the violation of encapsulation in OOP?

Thanks

Hi,

For multi paged threads when I click on the page number provided at the top of the thread,
I get the message "Howdy Pardner, unfortunately it looks like you've come to the wrong page or
maybe we've gone and moved that critter! "

Hope it will be resolved soon.

Regards,

Initializing_Array[] ia = new Initializing_Array[10];



You have created 10 reference of type Initializing_Array
It doesnt mean 10 objects of Initializing_Array.

So you have to create Object and assign to these refence, then only you able to set the values.

Hello,

I am trying to introduce authentication for some restricted resource in my we application.
I have introduced <security-constraint>.... </security-constraint> for secured resource and also I configured loginForm and loginError page.

So whenever I make a request to that secured resource, it asks for login id and password.

Now my issue is, the credentials I passed in the login form is not validated. Its always saying try again even if I provide the name/password that is present in tomcat-users.xml.

In server.xml , I added this line


In tomcat-users.xml, I modified,


Could you make out, what am I missing so that even if I enter aaaa/bbbbbbbb, why its not considerd as authenticated user?

-Thanks in advance

when you say conn=null, then its an indication to JVM is that, the object which conn is pointing is eligible for garbage collection(provided there no other reference to that object)

use RequestDisptcher object to servlet/servlet or servlet/jsp communication. Use include/forward method based on your requirement

Go to DB2 installation path. (Eg "C:\Program Files\IBM\SQLLIB\java" if its windows). There you find db2java.zip. Rename this to db2java.jar and use it.

Since you are using JSF framework, why are you going out of this framework? framework provides you the facility to seperate your business logic and navigation part. I dont think its necessary to forward the request to Servlet from a manged bean

to get the value set in the object of type ClassA, in the classes ClassB, ClassC, ClassD, you should have the reference of that object(ClassA) where the value is set , instaed of creating new objects in every class.
