Im using JSF1.2 and when i use the <f:view> tag in the jsf page, i got the above error.

i have all the required libraries(jsf-api.jar,jsf-impl.jar) in the web-inf\lib.

What causes the error??

there is no stacktrace.

Im using Jdeveloper. When i type in the tag <f:view> it show an error saying " Unable to instantiate tag: f:view (class: null) Make sure that the tag class is available and that the tag library containing the class is not excluded from this application."

So this is a problem of JDeveloper and not of JSF?
