Can't instantiate the class problem

[lenyas66]

I created a new class, which has very simple structure, but somehow JSF is throwing "cant instantiate exception", when I try to access it.

18:03:07,781 FATAL [application] JSF1001: Managedbean piPublisherBean could not be created.

18:03:07,781 ERROR [STDERR] May 13, 2010 6:03:07 PM com.sun.facelets.FaceletViewHandler

handleRenderException

SEVERE: Error Rendering View[/piPublisher.xhtml]

javax.faces.FacesException

: javax.faces.FacesException: Cant instantiate class: com.nb.pi.web.beans.PIPublisherBean.. com.nb.pi.web.beans.PIPublisherBean

Could somebody advise why it is happening? I think, I may have some really simple error, but can't see the cause.

I figured out what was the issue: it had nothing to do with this particular class, but rather with subclass, which had an error in XHTML file (referencing undefined variable).

I am curious though, why this would be an issue even before I attempted to load the screen, which had the problem? Does JSF try to instantiate all classes from faces-config.xml in advance?

Hi Leonid,

I am curious though, why this would be an issue even before I attempted to load the screen, which had the problem? Does JSF try to instantiate all classes from faces-config.xml in advance?

According to the log, exception happens during view rendering:

handleRenderException

SEVERE: Error Rendering View[/piPublisher.xhtml]

javax.faces.FacesException

so there should be request for this view.
