 I don't think the current mechanism is particularly onerous, since

 Tomcat supplies an ant script to do all the dirty work, including the
 update of web.xml.
 
 My understanding is that the ant script needs some help to get

 started: you can't simply run the JSP precompiler against an existing
 webapp without seeding web.xml, at least a bit.

I suggested generating annotated java a little while back and didn't get
an overly enthusiastic reception, but I like the general idea of the
JSPs being in their own jar.

I think it would be good if Tomcat 7.0 featured and used Servlet 3.0
functions, the source is available and it'll help users get to know the
spec.

An  enhancement bug has been entered for those with the itch. It appears 
the existing JspC task still writes out 2.3 when it writes a new web.xml.

JSP Precompilation and Servlet 3.0

2010-11-05 Thread Christopher Schultz

All,

Tim has just given his talk at ApacheCon NA about Servlet 3.0 / Tomcat
7.0. It was really my first taste of the 3.0 spec and I had a thought
about the new features available for webapp configuration /other/ than
web.xml:

- - web.xml fragments
- - class annotations

The current method for JSP precompilation (which I've never used, mind
you, so forgive my ignorance if I'm incorrect) is cumbersome:

- - run the compiler
- - copy the new .class files somewhere
- - drop a huge load of junk into web.xml

It occurred to me that that these new servlet 3.0 features could help
JSP precompilation. Let's see what Tomcat 7.0's JSP precompiler could do
(roughly):

$ jsp-precompile /path/to/jsps my-jsps.jar
$ cp my-jsps.jar /path/to/webapps/mywebapp/WEB-INF/lib

(done)

The precompiler could translate and compile all of the classes and
package them into a .jar file for you. Great. What about servlet
mappings? Well, we have two options:

1. Use annotations in the translated .java files
2. Generate a web.xml fragment and stuff it into
   my-jsps.jar/WEB-INF/web-fragment.xml

Does anyone have any preferences? I suppose it could be an option to the
precompiler, or we could even do both (do duplicate mappings conflict?).

Hopefully, this will make JSP precompilation less onerous for users.

Thanks,

Personally I do not like JSP precompiling.

1. I do not put into JSP anything that user should not see.
2. Cost of compilation with first request is acceptable.
3. Possibility to change produced markup either by me or customer is 
priceless.

Re: JSP Precompilation and Servlet 3.0

2010-11-05 Thread Tim Funk
While I like the idea of using web-fragment.xml for precompiled jsp's - 
it would require the meta-data complete flag to be set to false which 
may as a side effect allow other artifacts to be loaded too.


Hopefully jsp-precompile is part of the webapp build/deploy process so a 
developer can ignore it during development. But an admin (or release 
manager) can ensure that all jsps do compile before release is deployed.


Setting up jsp-precompilation is a PITA the first time or 2 but once you 
get the hang of it, the precompilation step can be part of a standard 
snippet which can be pulled in via ant import.  (For those of us who 
love ant)
