JBoss Developer Studio 4.x is not supported with Java 7, however you can complete installation with Java 6 and then follow a few steps to allow it to work with Java 7; though it must be stressed that this is not supported. Java 7 will be supported for JBoss Developer Studio 5. To use Java 7 with JBoss Developer Studio 4.x: - Install JBoss Developer Studio using Java 6 - After installation, navigate to the /studio/ folder of your installation. - Open the *jbdevstudio.ini* file in a text editor - Add the following lines to the end of the file: *-vm* *  JAVA_7_FOLDER/bin/java* - Replace *JAVA_7_FOLDER* with the path to your Java 7 installation - Save the file and exit your text editor When you next launch JBoss Developer Studio 4.x it will use Java 7. There are a number of other things you can configure in the *jbdevstudio.ini* file.
