ClassNotFoundException

[allvi]

If I start Wildfly and deploy my war file I get following ClassNotFoundException.

Why Wildfy cannot find the exception class?

Thank you in advance for your answer

What version of WildFly?

I am bit guessing here but looks like exception comes from here

errorPage = new ErrorPage(page.getLocation(), (Class<? extends Throwable>) module.getClassLoader().loadClass(page.getExceptionType()));

Which is during resolving error-pages configurations from your web.xml

can you make sure your configuration is correct there?

Thank you for your answer.

Now I have removed following lines from my web.xml for WildFly 8.0.0 Final and 8.1.0 CR2 and the error disappears.

	<error-page>
	<exception-type>Exception</exception-type>
	<location>/faces/pages/error/error.xhtml</location>

    </error-page>

PS:

The above lines in web.xml worked with JBoss 7.1.1 final.

I would say that AS7.x was wrong then.

if you look at xsd and/or specification for this element, you will see that it expects fullly qualified class name.

in your case it should be

<error-page>

       <exception-type>java.lang.Exception</exception-type>  

       <location>/faces/pages/error/error.xhtml</location>

</error-page>
