P.S.: Have tested my implementation with Nashorn on Java 8 and it works out of
the box! Still, you
would need to test the implementation thoroughly yourself (stability,
performance, resources) and
would be asked to come back with feedback on each of these qualities. So stay
tuned, will
publish a
link to the implementation with a proper Nashorn/JavaScript sample war in this
mail thread in a
few
days.
How cool is this! Let me know when you it ready, please. Thanks a lot!
O.K., had a few things I could finalize. Created two war files,
"demoJavaScript.war" and
"demoRhino.war". The first got tested against Nashorn, the second - you guessed
it ;) - against
Rhino (7.1.13). They are meant as little proof-of-concepts that should help you
to get up and
running with them.
Please note that the libraries are beta, though appear to be stable. Yet, there
may be
errors/problems in them or there may be changes coming up.
If you have feedback of any sorts, please come forward (stability, usability,
performance,
resources, etc.).
Basically you just need to go to [1] and get the two war-files (copy to
$CATALINA_HOME/webapps) plus
either javax.ScriptTagLibs.jar (for Tomcat 9 or earlier) or
jakarta.ScriptTagLibs.jar (for Tomcat
10) which you should copy to the shared directory at $CATALINA_HOME/lib and
restart Tomcat to get
them recognized. If you want to test with Rhino you should follow the
directions at [1] and copy the
mentioned two rhino jar files to the shared library directory as well.
In general you should take the time and look over that page at [1], I tried to
remain as brief as
possible. :)
Also please do not forget that the target audience of [1] has been so far the
Rexx community and my
BA students who learned programming using ooRexx in a semester and with that
knowledge should now
become able to create little web sites for their own purposes and maybe with
some experience for
small businesses/organizations given the information at [1] as a starting point.
Of course, if there are any questions please do not hesitate and please ask
them!
Any source available?
Sure, sorry forgot to point that out explicitly!
You can get at it either in the ScriptTagLibs jar files from [1] (yes, in this
case I have the
source and also the tld files in the jar for completeness as well) or from [2]
with the appropriate
checkout strings given in the upper half.
Also, the license is AL 2.0, of course (dual licensed with the CPL 1.0 license
in addition which the
ooRexx project uses).
Please note: currently the state is beta, it is functional and appears to be
stable.
This is a pretty awesome effort. Since you work at a university, perhaps
some of your students would be interested in working on the library
itself and not just in being an end-user. Maybe CS students at the same
uni though not in your program. They could probably get credit for
working on it, too.
A request: if you see something questionable, improvable or missing, please be
so kind and let me know!
There is certainly room for improvements, especially through the eyes of an
Tomcat/Servlet expert
like yourself! :) E.g., it would be nice to put the tld files into the jar and
allow the JSPs to
refer to them without the need to copy them to WEB-INF as is possible with the
STL ; if I knew how
to do that, I would do it as it improves usability (ran out of time to research
that specific feature).
Just put your .tld files in META-INF/ in your JAR file and Tomcat should
detect them. You will need to put those files into the web application's
WEB-INF/lib directory. (I think... I can't remember if Tomcat checks
CATALINA_BASE/lib/*.jar for TLD files or not.)
