JDeveloper supports 64-bit versions of Windows and Java

There is a small note in the JDeveloper Installation Guide:

This release of Oracle JDeveloper supports the 64-bit versions of Windows and Java.

More on the question What is 64-bit Java?, can be found on this Java Hotspot FAQ.

The Installation Guide mentioned before doesn’t show additional details on How-To get JDeveloper working on Windows 7 with an 64 bit Java version….
To get this working:

  • Download and install a recent 64 bit JDK for Windows 7 64 bit, eg jdk-6u24-windows-x64
  • go to the $Middleware_Home$\jdeveloper\jdev\bin directory and edit the jdev.conf
  • Alter the SetJavaHome to the directory in which you just installed the JDK:
# Directive SetJavaHome is not required by default, except for the base
# install, since the launcher will determine the JAVA_HOME.  On Windows
# it looks in ..\..\jdk, on UNIX it first looks in ../../jdk. If no JDK
# is found there, it looks in the PATH.
#SetJavaHome C:\Oracle\Middleware\jdk160_21
SetJavaHome C:\Program Files\Java\jdk1.6.0_24
  • And then start the jdev64W.exe in the $Middleware_Home$\jdeveloper\jdev\bin directory.

Additional hints

February 2012 Spyros Doulgeridis posted on his blog on Running JDeveloper in 64 bits. He shows additional guiding on:

  • Adjust JDeveloper’s memory settings in in the C:\Oracle\Middleware\jdeveloper\ide\bin\ide.conf
  • Increasing the memory of the embedded weblogic – in the setDomainEnv.cmd file
  • Configure Windows pagefile – to avoid the Virtual Memory Minimum Too Low error in Windows

    You can better install the generic version with jdeveloper with a 64 bits jdk. After that the internal weblogic server is also optmized for 64 bits ( it generates some 64bits dll for native io ).
