Installing an all 64 bit JDK JDeveloper set on Windows7

You might know that JDeveloper is supported on 64 bit versions of Java and Windows since release 11.1.1.4. Fusion Middleware is supported on JDK7 both 11g and 12c versions since May 2012. So I decided to try to install an 64 bit JDK7, 64 bit JDeveloper on Windows 7 64 bit.

Since most of my JDeveloper work is aimed at SOA Suite, BPM and non-ADF Java, I choose the JDeveloper 11g IDE. On the JDK site I started with JDK7u6. However a security thingie got in the way and I switch to JDK7u7. I’m assuming you have a PC/laptop/VirtualMachine running a 64 bit version of Windows7.

Install JDK7 update 7


The latest JDeveloper support/certification info states:

  • 64 bit JDK supported for Windows as of JDeveloper 11.1.1.4.0
  • For JDK 6, update 24 or later is recommended
  • For JDK 7, update 3 or later is recommended

However due to the security vulnerabilities in all earlier JDK 7 versions (on all OSes and their browsers) it is recommended to install only JDK7 update 7 and up.

Download JDK 7 for Windows 7 64bit. To install JDK7 on Windows7 double click the downloaded file.

Install JDeveloper 11.1.1.6


Since we have chosen a 64 bit JDK ourselves we downloading the jdevstudio11116install.jar from OTN Developer Tools site.

Before installing we check whether the correct JDK version will be used (from the command prompt (cmd)):
C:\Oracle\jdk7u7\bin>java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

C:\Oracle\jdk7u6\bin>

And then to install JDeveloper from the command prompt (cmd):

C:\Users\deltalounge\Downloads>java -jar jdevstudio11116install.jar

Then a GUI starts and the most important screens are:

Install SOA Suite, BPM and AIA extensions


Follow the guidance of these post to install JDeveloper extensions:

And you are ready to go.

JDeveloper on 64-bit Windows7

For a lot of us the migration to Windows7 will be the first time we get easy access to a 64-bit desktop OS. One of the first things after an upgrade like that is to get your tools, like in my case JDeveloper, working again. First step is to download the jdevinstall jar, and the Sun JDK. The installation worked fine:

1
java -jar jdevstudio11112install.jar

Running JDeveloper on 64-bit JVM

Running JDeveloper with the 64-bit JVM resulted in an error:

3
Unable TO launch the Java Virtual Machine  
located at path:  
C:\Java\jdk1.6.0_18\jre\bin\server\jvm.dll

A solution is to use the 32-bit JVM. To do this change the SetJavaHome in thejdev.conf that is located in the {JDEV_HOME}\jdev\bin\jdev.conf.

1
SetJavaHome C:\Java\jdk1.6.0_18_x86

Where the jdk1.6.0_18_x86 is a 32-bits JVM version.
