Oracle SQL Developer Unable To Find Java Virtual Machine

The Oracle SQL developer is NOT supported on 64 bits JDK.

Your PC environment may be :

Database : Oracle 11g / OS Platform : Windows 7 Ultimate 64 bits / JDK : 1.6 .0_24, 64 bits

So it will give you an error when trying to open SQL Developer.

When you click on the Oracle SQL developer, it prompts you to give the JDK folder location. However, after you specified the correct JDK folder, it prompts you following error dialog box :

Unable to find Java Virtual Machine. To point to a location of a Java Virtual Machine....

Solution

To solve it, install a 32 bits / x86 JDK and update your SQL developer config file, so that it points to the 32 bits JDK.

Edit the “sqldeveloper.conf“, which can be found under {ORACLE_HOME}\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf, make sure “SetJavaHome” is pointing to your 32 bits JDK.
