Mikhail Grushinskiy commented on JBSEAM-2141:

"Compiling the JSP EL to bytecode" by Chris Nokleberg


looks very interesting...


>This zip file ( http://sixlegs.com/misc/el.zip ) includes the entire project: Ant build file, JUnit tests, and all
>the necessary libraries. It uses ASM 3.0 (beta) for bytecode generation, and
>Jar Jar Links ( http://jarjar.sf.net/ ) to embed the ASM libraries when building the library Jar file. The source uses 
>the same license as GNU Classpath (GPL with library >exception).
>If people are interested in working on the code, let me know and I'll register a project somewhere like SourceForge.

I hope JBoss could consider it for its JBoss-EL implementation

> The idea is to add a new tag to declare types of the variables used on a page and use this type information
> to compile EL expressions into byte-code during initialization (deployment)
> Ex:
> If the page contains at the beginning
> <s:typedef var="myBean" class="com.company.package.Bean" />
> then all EL expressions can be compiled into bytecode at initialization time (and no reflection will be used for myBean access.
> <h:outputText value="#{myBean.subBean.property}" rendered="#{myBean.renderText}" />
> Some examples of implementation of compiled EL can be found here 
> http://sixlegs.com/blog/java/compiled-el.html
> This should help much with JSF performance issues
> Thanks
