title: How to make a jPanel semi transparent?
body: <p>I want to add a jPanel which is semi transparent. But other components which are placed inside the jPanel such as buttons and labels should be displayed with 100% opacity. I am using netbeans to  design the GUIs. Normally i drag and drop the swing components in the palette to design the GUI(I don't code them). I can't see any property in properties window to achieve this. Please help me. As I am quite new to java please give me a detailed answer. Thanks in advance.</p>
