After spending enough time on installing Oracle SQL Developer and respective issues, I thought of writing few easy steps to install it. Hope it would help and save your time. Steps to install Oracle SQL Developer(for windows): Download SQL Developer from Oracle site. Download Download JDK if it is not installed on your machine. Download Install JDK and then unzip SQL Developer Click on sqldeveloper.exe, it will ask for java.exe path Open the path where JDK is installed. It would be something like "C:\Program Files\Java\jdk1.7.0_40\jre\bin" depeneding upon which version you install. If it is giving any exception, remove the entry [SetJavaHome] from sqldeveolper.conf file from "..\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf" and give the correct path of java.exe file. Please provide your feedback if you like the post.
