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.

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.

like

for(int i=0; i < ia.length; i++){ ia[i] = new Initializing_Array(); }

<servlet-mapping> <servlet-name>ServletHome</servlet-name> <servlet-name>ServletOne</servlet-name> <url-pattern>/Vij.jsp</url-pattern> </servlet-mapping>

Here you are mapping url-pattern to two different servlet name.

hello Tim,

as you mentioned, j_security_check displayed in the browser..

http://localhost:8080/logintest/secure/j_security_check

where I might be going wrong? I have changed in server.xml of tomcat directory and web.xml of application.
Any other file I need to be changed?

-Thanks

Thanks Misha for your reply..

<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml"
readonly="false"
/>

is alredy present in server.xml..

Any other hint that I need to try?

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
<Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>

In tomcat-users.xml, I modified,
<tomcat-users> <role rolename="abc"/> <user username="aaaa" password="bbbbbbbbb" roles="abc" /> </tomcat-users>

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)

Hi Bue,

I don't see any try block for the second catch block
catch (Exception n) { System.out.println("Error!"); }
that you have written

make sure its db2java.jar and not db2java.zip

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

Class ClassB { private ClassA ca; //some arrangement like this has to be made, so that ClassB will have the handle to the object(of ClassA) where you have set the value from db. public setCa(ClassA objCa){ this.ca = objCa; } void fun() { int a=ca.getIDVal(); } }

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.
