Attaching remote debugger in Netbeans

I am working on a web application based on Ant,Struts and Java. I wanted a way to debug the live application in my local environment and I found out that attaching remote debugger is the best option. It helps in debugging live application.

What is Remote Debugging?

The client/server design of the Java debugger allows you to launch a Java program from computer on your network and debug it from the workstation running the platform. This is particularly useful when you are developing a program for a device that cannot host the development platform [source: eclipse community]

How to enable it in Netbeans

Open Netbeans IDE
Go to Debug option
Click on Attach Debugger
Enter the host name and port number
Click OK

Note: Make sure you start the application first before attaching the remote debugger

Enabling TLS 1.2 in Java 7

I am working on web application that uses third party API and apparently those guys have stopped using TLS 1.0 and switched TLS 1.2

I was getting the following error

Apparently Java 1.8 have TLS 1.2 by default and for Java 1.7 you have to enable it. I have been searching online for few days to enable TLS 1.2. I have tried all the following things but it did not work

For each application, enter this command:java ... -Dhttps.protocols=TLSv1.1,TLSv1.2 ...
Using JAVA_OPTS, enter the following command in your .profile, shell rc (to affect all Java programs run by the user), or conductor.sh (to just affect Datameer):export JAVA_OPTS="${JAVA_OPTS} -Dhttps.protocols=TLSv1.1,TLSv1.2"
This is what I did and boom it worked
