To be honest, I haven't tried. I imagine it would be somewhat simple though. However, since I really know nothing about OGNL, it might be a lot more difficult than I'm thinking. To add JSTL Support, I simply subclassed the two Table and Column Tags and added an ExpressionEvaluator to do the evaluation of Strings.
http://displaytag.sourceforge.net/xref/org/displaytag/tags/el/package-su mmary.html The one ugly issue right now is we are maintaining a separate TLD for the original tag library and the EL version. I suppose we could use XDoclet to generate this and that might solve the problem, but I imagine the main developers are little hesitant to adding another TLD to the mix. That being said, I'm more than willing to hack a local copy and make this work. I think if I do this same sort of logic (see below) with OGNL - it'll be a breeze. ExpressionEvaluator eval = new ExpressionEvaluator(this, pageContext); if ((s = eval.evalString("decorator", _decorator)) != null) { super.setDecorator(s); } ... Replacing Expression Evaluation with one from OGNL...
