[jira] Created: (MYFACES-384) Allow Pre-compiling web application for Tomcat
Allow Pre-compiling web application for Tomcat
----------------------------------------------
Key: MYFACES-384
URL: http://issues.apache.org/jira/browse/MYFACES-384
Project: MyFaces
Type: Improvement
Components: General
Versions: 1.0.9 beta
Environment: Tomcat -- Jasper2
Reporter: John Schneider
Priority: Minor
Pre-compiling web applications for Tomcat is not supported "out of the box" as it should be. I have written a filter that performs essentially the same function as FacesServlet, so that each individual JSP servlet can be defined and mapped in web.xml. However, limitations in myfaces.webapp.webxml.WebXml.getFacesServletMappings() prevents these mapped servlets from rendering the view.
The code in question is: if (FacesServlet.class.isAssignableFrom(servletClass)) {
This will prevent any pre-compiled page from being added as a faces servlet mapping, as these servlets extend org.apache.jasper.runtime.HttpJspBase.
The applicable stack trace is as follows:

[jira] Commented: (MYFACES-384) Allow Pre-compiling web application for Tomcat
Posted by "John Schneider (JIRA)" <my...@incubator.apache.org>.

John Schneider commented on MYFACES-384:
----------------------------------------
I've finally had some time to work on this issue, and have come up with a possible solution.
I have tested the patch below on Tomcat 5.5 in a very simple web app. You can recreate the environment with the FacesFilter and web.xml above.
The only difference is in web.xml, change:
<servlet-mapping>
<servlet-name>org.apache.jsp.success_jsp</servlet-name>
<url-pattern>/success.jsp</url-pattern>
</servlet-mapping>
(changed /success.jsf to success.jsp)
I would appreciate it if others could test this in other environments. It would be nice to add support for precompilation for the next MyFaces release.

What's the status of this issue. It seems there was a solution supplied quite some time ago, did it ever make it into any builds?
