What is the purpose on why you want to bypass the Security? Is your purpose is for testing so that you don't need to go on login?

Just comment the security-constraint code:

<!-- <security-constraint> . . . </security-constraint> -->

Are you talking about Java Source Code Scanner? If yes. a java code scanner is a just a utility that will help you determine if there are code that is not being used. If your using eclipse like the Fully loaded eclipse, there is simple example of a java code scanner like if you see a yellow underline of your variable that means that it's not being called but it maybe being used as a storage. If you're using IBM RAD 7 or RAD 7.5, you can set the tools to help you trace what are those code that is not used. There is a tool for JSC http://pmd.sourceforge.net/.

JDBC is slight similar to JNDI because they are both OO Java API. The JNDI is mostly used for accessing a native interface while the JDBC is more on relational database. You can use JDBC without JNDI or you can use both. Based on your question, the JNDI, JDBC and DataSource can be used together for a purpose. Based on my previous project I used bought because it is part of the technical requirements and I implemented it through Web XML and on my other project I used the Spring Configuration.

The JNDI part was stored on WebSphere variable, so I used the JNDI to call it. The datasource is created on the WebSphere DB connection and the JDBC is my driver or connector type. In WebSphere you can use any type of JDBC, but on my project I used JDBC type 2 because I don't need advance features which is on JDBC type 4.

DataSource reference by JDBC and JDBC can be called by JNDI. For simplistic way: JNDI ( JDBC (DATASOURCE)))

This is just my thought.

I don't know if this will help your problem.

I have found some solution on enabling the JConsole on WAS 6.1 and maybe we are on the same page this link http://www.interface101.org will show some of the post that will guide you to enable JConsole on WAS 6.1

I saw some post on the http://www.interface101.org on enabling the JConsole on WAS 6.1. I did follow that procedure and it works what I expect.

While studying the SCJP 1.6, I found out that it's slight similar to SCJP 1.5. I think the best way to met the objectives is practice and know the basic.
