The JSTL specification doesn't specify an API to the EL engine, so you'll have to rely on an implementation that gives you an API for this. You can use the Jakarta Taglibs implementation for this. If you look through the classes in this library, you'll find both the "ExpressionEvaluatorManager" and "ExpressionUtil" class. The former class is probably the better one to use for this, but the latter would be more concise. You can also see an implementation of a library to do exactly what you're trying to do, in the implementation of the "Struts-EL" contributed library in the Struts distribution. Look at the source in the nightly build for this.
