Hi I am planning to add facelet support to an already existing project of
mine. I addded the follwing three libs jsf-facelets.jar, el-api.jar and
el-ri.jar and the other jars in my lib are the commons (4) jars,
jsf-api,jsf-impl, jstl, standard and tl-common.jar. I added a very simple
facelet page (the number guess example) and tried to run it but got the very
same error :
Error Rendering View[/facelet1.jsp] Could not instantiate
feature[compiler.ExpressionFactory]: com.sun.el.ExpressionFactoryImpl
at com.sun.facelets.compiler.Compiler.featureInstance(Compiler.java:153)
	at
com.sun.facelets.compiler.Compiler.createExpressionFactory(Compiler.java:142)
	at
com.sun.facelets.impl.DefaultFaceletFactory.createFacelet(DefaultFaceletFactory.java:193)
	at
com.sun.facelets.impl.DefaultFaceletFactory.getFacelet(DefaultFaceletFactory.java:141)......

According to this post this should have been resolved if we had the el-api
and el-ri jars in my lib folder. These libs have been added to the class
path and btw i downloaded the jars from the java.net site. 

What else can be the problem. For facelets I have added a single entry in
the faces-config.xml file for the view-handler. Do I need to make more
changes in this file or any other file. Thanks for the help.
