Geronimo 2.1.x, standard MyFaces bundle, org.apache.myfaces.ERROR_HANDLER in web.xml - classloading problem
Hello,
I'm trying to write own ErrorHandler for handling Exceptions. It's based on Tomahawk ErrorRedirectJSFPageHandler with some other attributes in ExceptionContext (error identificator for BFU etc.).
When I deploy web application under common way (WAR), all is OK, but when MyFaces catches exception and try to redirect processing to my own handler (specified in web.xml by parameter org.apache.myfaces.ERROR_HANDLER) I got error from Tomcat:
javax.servlet.ServletException: Error-Handler : cz.pajasoftovi.TestJSF.ErrorRedirectJSFPageHandler was not found. Fix your web.xml-parameter : org.apache.myfaces.ERROR_HANDLER
javax.faces.webapp.FacesServlet.handleLifecycleException(FacesServlet.java:248)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:160)
root cause
java.lang.ClassNotFoundException: cz.pajasoftovi.TestJSF.ErrorRedirectJSFPageHandler in classloader org.apache.geronimo.framework/jee-specs/2.1.4-SNAPSHOT/car
org.apache.geronimo.kernel.config.MultiParentClassLoader.loadOptimizedClass(MultiParentClassLoader.java:438)

javax.faces.webapp.FacesServlet.service(FacesServlet.java:160)
Yes, I known this is classloading issue... so I'm trying to add MyFaces JSF (1.2) implementation (myfaces-api, myfaces-impl) to application WEB-INF/lib directory and in Geronimo deployment descriptor I'm hiding javax.faces and org.apache.myfaces to prevent loading the Geronimo server version of MyFaces (my and Geronimo version are though identical) and all is working AS EXPECTED.
So my simple question is how to modify web.xml (or better in geronimo-web.xml) to working as expected with Geronimo server bundled MyFaces package? How to modify classloading by deploy descriptor (inverse-classloading... don't work)? It's possible by modify deploying descriptor or some special GBEAN configuration is required? I don't like to distribute own version of MyFaces...
Thanks

Hello,
thank you very much, this is the point of my search..:-) Sometime is
darkness under lamp'-).
I thought - if I specify dependency (MyFaces-impl for ex.) and also specify
hidden-classes filter, those classes are not visible in classpath... so If I
have some reference(-s) (in faces-config.xml for ex.) I got the error during
deploying...

Hi Ivan,
the smallest WEB application that I can imagine is
http://www.fonet.cz/MyFacesERROR_HANDLER.zip there - it's Eclipse project.
If it is better for you direct deployable WAR - it's
http://www.fonet.cz/MyFacesERROR_HANDLER.war here (each around 1MiB). After
deploying and starting, application will give you one item in menu and when
you click on "Get NullPointerException", you get custom error page via
org.apache.myfaces.ERROR_HANDLER setting parameter in web.xml. This use-case
only works for me when I bundle MyFaces JARs with application in
WEB-INF/lib. (the real application is much more larger EAR with many EJBs
and other components of course...)
I'm searching possible way to distribute similar application without MyFaces
(I want use server bundled version of MyFaces - only to specify dependencies
in deployment plan as usualy).
Thank you for your time.

Hello Ivan,
without dependency of myfaces-api and impl (or including their jars in
WEB-INF/lib dir) deploying process always fail:
2009-02-27 11:05:49,556 ERROR [[/NPKWebShop-WEB]] Servlet /NPKWebShop-WEB
threw load() exception
java.lang.IllegalStateException: No Factories configured for this
Application. This happens if the faces-initialization does not work at all -
make sure that you properly include all configuration settings necessary for
a basic faces application and that all the necessary libs are included. Also
check the logging output of your web application and your container for any
exceptions!
If you did that and find nothing, the mistake might be due to the fact that
you use some special web-containers which do not support registering
context-listeners via TLD files and a context listener is not setup in your
web.xml.
A typical config looks like this;
<listener>
<listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1064)
at org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:966)

.
.
I try this plan as you suggest (and remove myfaces-api and impl jars from
WEB-INF/lib directory):
<dep:environment>
<dep:moduleId>

<dep:hidden-classes>
<dep:filter>javax.faces</dep:filter>
<!--
<dep:filter>org.apache.myfaces</dep:filter>

</dep:hidden-classes>
</dep:environment>
(facelets are deployed to repository by me because I'm using it) and I got
the same java.lang.IllegalStateException as on top of my post... so I try to
specify listener in web.xml as suggested, but the results is the same -
IllegalStateException.
Any idea?

It should have the same effect with copying those myfaces jars into the lib
folder.
