> There are two jars (jboss-jsp-api_2.3_spec-1.0.0.Final.jar and jboss-jstl-api_1.2_spec-1.0.4.Final.jar) that are incompatible with each other due to a bug -- both are storing an object in the same place, but the objects are not compatible.
> The result is that a jsp page cannot contain both JSTL and Spring tags, or it will get that error.
