The Oracle WebLogic server integration enhancements include fast turnaround when redeploying applications; deploy on save; datasource management; server library configuration; the ability to explore deployed applications and resources, and to view server logs and the admin console from within the IDE.
Additional highlights include Maven 3 and HTML5 editing support; a new GridBagLayout designer for improved Swing GUI development; enhancements to the Java editor, and more.
