Subject Question ad alternative of BSF taglib in Tomcat ? [Fwd: In the move of some taglibs to Tomcat, the BSF taglib got retired]
Date Fri, 09 Oct 2009 11:30:43 GMT
Hi there,

not sure whether this is a user or dev question, hence sending it to
both, please forgive, if wrong.

Learning about the finalization of moving taglib from jakarta to tomcat,
one could also learn that the BSF taglib got retired in the process.
AFAIK the BSF taglib has been allowing one to add code in all of the BSF
supported scripting languages to JSPs. Not knowing, wheter there are
alternatives available in the current Tomcat (did a coarse research on
that issue, but did not find any info on this) I created the enclosed
e-mail to the BSF user and dev list to make sure, that users of the BSF
taglib learn about where it has moved to, in case it is still needed.

In case the BSF taglib is needed for adding scripts in scripting
languages to JSPs, I would kindly suggest to not retire it, but to keep
it available for interested parties in the Tomcat realm. In case there
are alternatives available in Tomcat to the BSF taglib, please be so
kind and point them out (just short pointers would suffice!).



P.S.: If the BSF taglib is still needed, then one more (dev) point to
discuss/raise would be to create in a addition a new JSR-223/BSF3 taglib
for the newly released BSF 3.0, which implements the JSR-223
(javax.script) specs. Unlike JSR-223, which is only available starting
with Java 6, BSF 3 supplies the same functionality for Java 1.4
installations or higher, making it a very attractive technology for Java
1.4 and 1.5 installations, as they gain the standard scripting APIs with
it. There would be more to this, but should only be discussed, if a need
for this exists.

Hi there,

just learned from the announcement that in the process of moving taglibs
from Jakarta to Tomcat a lot of taglibs got retired, among them the BSF

Not sure at the moment how Tomcat will allow for creating JSPs that
embed code in scripting languages, which was one of the original
applications of BSF, when it was originally developed at IBM (as a
matter of fact, IBM's WebSphere distributed BSF in order to enable Java
Server Page authors to embed scripts in any of its supported scripting
languages, very much like MS allows for in their ASPs).

So for those who have a need for the BSF taglib, here the relevant links:
