myFaces (Jsf) and Class.forName ...Does It Work in an OSGI env?

[Beta User]

hi all,

one question: is the following code supposed to work in an osgi environment?

from myfaces-1.1.5 FacesConfigurator#getApplicationObject
.
.
// com.springsource.org.apache.myfaces-1.1.5.jar loading NavigationHandlerImpl from trinidad bundle
Class implClass = Class.forName("org.apache.myfaces.trinidadinternal .application.NavigationHandlerImpl",
false, Thread.currentThread().getContextClassLoader());
.
.
// javax.faces.application.NavigationHandler.class loaded from com.springsource.org.apache.myfaces.javax.faces-1.1.5
if (NavigationHandler.class.isAssignableFrom(implClas s)) {
// THIS condition is never true/fulfilled !
}
.
.

do i have to package myfaces,trinidad and facelets into one library so that they can 'see' each other?

thx m

It should be fine to package myfaces, trindad and facelets as separate bundles. The use of Class.forName() may cause a problem, but it seems that the thread context classloader is being used, so I would expect the class to be loaded correctly.

Can you create a JIRA and attach a simple failing case for us to check?

hi rob,

thx for your answer...one more question..do you know any issues/problem with Class#isAssignableFrom testing 2 classes coming from different classloaders?

thx
