Author: remy.maucherat(a)jboss.com Date: 2009-02-25 08:04:57 -0500 (Wed, 25 Feb 2009) New Revision: 940 Modified: trunk/java/org/apache/jasper/Constants.java trunk/java/org/apache/jasper/compiler/JspDocumentParser.java trunk/java/org/apache/jasper/servlet/JspServlet.java Log: - Fix portions of the code which seemed obviously at odds with the concept of providing (most of the) TLD data from JBoss metadata. - Right now, it seems replacing the options with a JBoss class which would use the caching mechanism and provide a new TagLibraryInfo implementation is the right way. If a TLD is not found, it will use the old Jasper mechanism.
