Installing JDeveloper Now that you have downloaded the latest version of JDeveloper from: the Oracle technology network, you are almost ready to install it. The problem is that the GUI installer is not as accessible as it could be. However, there is an alternative called a silent install. To perform a silent install, follow these steps: Download the silent.xml file into the same folder as the JDeveloper installer. You can customize the silent.xml file by setting the folder where JDeveloper will be installed, and by setting the location where you have a 1.6 jdk installed with the accessbridge already configured. The defaults are: JDeveloper wil lbe installed at c:\jdev a jdk is installed at c:\jdk\1.6.0_25 (see instructions in the top of the silent.xml file). Open a command window and navigate to the folder where the JDeveloper installer and silent.xml files are located. Run the following command: jdevstudio11120install.exe -mode=silent -silent_xml=silent.xml -log=install.log Note: this assumes that you are installing JDeveloper 11.1.2.0.0. Change the above command to match the installer package you have. This command will start by extracting the archive then the oracle installer will launch, but you just have to wait until the command prompt returns and voila it will be installed. To run JDeveloper: Now you can use windows explorer to navigate to the %JDEV_HOME% as specified in the silent.xml file (c:\jdev unless you changed it)and drill down to: jdeveloper\jdev\bin and now you have a couple of choices. If you have a 32-bit jdk configured with the accessbridge, then run jdevw.exe, however, if you have a 64-bit jdk copnfigured with the accessbridge, you should run jdev64w.exe. For instructiosn on setting up Accessbridge 2.0.1, see my earlier post.
