问题
So I have downloaded:
Oracle SQL Developer 4.2.0.17.089.1709 Windows 32-bit/64-bit version
Extracted it to a Windows 7 SP1 32 bit machine to the C drive C:\sqldeveloper
When I run sqldeveloper.exe nothing happens.
EDIT:
I have also installed JRE 1.8.131 jre-8u131-windows-i586 & JDK 1.8.131 jdk-8u131-windows-i586
Congratulations! You have the recommended Java installed (Version 8 Update 131).
Running it in CMD by using:
cd C:\sqldeveloper\sqldeveloper\bin and running sqldeveloper.exe and get the following error:
Error occurred during initialization of VM
java/lang/ClassNotFoundException: error in opening JAR file
C:\sqldeveloper\jdk\jre\lib\rt.jar
回答1:
Did you install Java 8 Development Kit (JDK). Oracle need Java
回答2:
After some troubleshooting it ended up being an issue with having multiple versions of JRE & JDK installed (both 1.8.121 and 1.8.131 for JDK & JRE).
I deleted the older 1.8.121 fodlers and re ran sqldeveloper.exe and it asked me again for the location of JDK, pointed it to the 1.8.131 folder and it worked.
