Oracle SQL Developer Unable To Find Java Virtual Machine

转自：http://www.mkyong.com/oracle/oracle-sql-developer-unable-to-find-java-virtual-machine/

Problem

Here’s my PC environment :
Database : Oracle 11g
OS Platform : Windows 7 Ultimate 64 bits
JDK : 1.6 .0_24, 64 bits

While click on the Oracle SQL developer, it prompts me to key in the JDK folder. However, after i specified the JDK folder, it prompts me following error dialog box :

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

see figure below :

Solution

Oracle SQL developer is NOT support 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.

Fix it!

Edit the “

sqldeveloper.conf

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

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