Setting Environment variables for Java

• JAVA_HOME : C:\Program Files\Java\jdk1.8.0_102
• JDK_HOME : %JAVA_HOME%
• JRE_HOME : %JAVA_HOME%\jre
• CLASSPATH :.;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib
• PATH : your-unique-entries;%JAVA_HOME%\bin (make sure that the longish your-unique-entries does not contain any other references to another Java installation folder.

Notice that all these environment variables are derived from the "root" environment variable JAVA_HOME. This makes it easy to update your environment variables when updating the JDK. Just point JAVA_HOME to the fresh installation.

Solution to 'Could not find the main class, program will exit' while executing runnable file

This error usually happens if there is a conflict in the Java installations. It means there may be more than one installation of Java in your system. Mostly presence of Oracle Jinitiator in C:\Program Files (x86)\Oracle creates this problem.

Perhaps your file associations got messed up. At the command prompt, try running

ftype | find "jarfile"

On my 64-bit Windows 7 computer, that shows

jarfile="C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -jar "%1" %*

You can also change it with ftype:

ftype jarfile="C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -jar "%1" %*

and reboot the system. 

You may also uninstall the Jinitiator which is no longer supported by Oracle as per our knowledge.

Creating Runnable Thread in Java for Selenium User Interface for avoiding no response while execution

UI elements in a User Interface will not respond to the user while execution if a thread is not implemented. Here I will explain how to create a thread so that User Interface will keep responding to the user even when the execution is happening.

Create a class outside the Jframe class

class Multi3 implements Runnable{ 

public void run(){ 
    Url url= new Url();
    url.openurl(javaframe.textField.getText());
}
}

Call the Thread from any actionlistener like below

Multi3 m1=new Multi3(); 
                Thread t1 =new Thread(m1);
                t1.start();
