<title>OGNL Overview</title>
<body>
<p>OGNL stands for Object-Graph Navigation Language; it is an expression language
for getting and setting properties of Java objects. You use the same expression
for both getting and setting the value of a property.</p>
<p>OGNL started out as a way to set up associations between UI
components and controllers using property names. As the desire for
more complicated associations grew, Drew Davidson created what he
called KVCL, for Key-Value Coding Language, egged on by Luke
Blanshard. Luke then reimplemented the language using ANTLR, came up
with the new name, and, egged on by Drew, filled it out to its current
state.</p>
<p>We pronounce OGNL as a word, like the last syllables of a drunken
pronunciation of "orthogonal" or like "ogg-null".</p>
