Oracle SQL Developer unable to find Java Virtual Machine

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

For example, “SetJavaHome C:\Program Files (x86) \Java\jdk1.6.0_13“.
