Resending attempt. ---------------------------- Hi Henri,
relating to our conversation of last fall, I just wanted to point out that Mr. Ryabenkiy posts of today (copied at the end to inform the BSF-community) fulfills the idea of creating a jsr-223 taglib for Tomcat. He applies the Apache License 2.0 to his work, such that it can be taken on by ASF. The Quercus/Resin <http://www.caucho.com/resin-3.0/quercus/tutorial/module/index.xtp> package Mr. Ryabenkiy refers to is used in his work as proof of concept to use PHP scripts in Tomcat served JSP (which might be quite interesting for PHP-acquantied programmers, who have no expert knowledge of Java) ! (He also uses the scripting language ooRexx as a proof of concept for which he wrote a JSR-223 engine.) In effect all scripting languages can be used, that adhere to Java 6 scripting a.k.a. "JSR-223" with his taglib to create scripts for JSP. It would even be possible to use multiple scripts in different languages for the same JSP. It will (again) allow for JSP and Java what ASP allows for the MS world. ---rony On 13.10.2009 08:17, Rony G.

IMHO, this announcement is relevant to both communities. This is to inform the taglibs-user and tomcat-dev communities of a small new taglib which allows to script JSP pages in laqnguages other than Java. Scriptlets and expressions using the taglib have access to the same implicit objects normal JSP scriptlets have access to. Internally, the taglib only depends on the javax.script interface defined as part of JSR-223 and included in Java 6 onwards, although it can also work with other implementations of javax.script on earlier version of Java (such as, for instance, Bean Scripting Framework 3). So for people who want to include scripts in their JSP pages, any scripting language that exposes a javax.script interface can be used. Given the nature of the project, and the existence of partial alternatives at least for some languages (such as Quercus/Resin), I expect interest to be quite small (if any), but if there's any interest it could be included in the newly re-organized "Extended" Taglib. Ideally, I would want Tomcat to support this kind of functionality natively via the language attribute of the page directive, but the taglib at least offers a simpler and container-independent solution.
