[pino astarita]

Hi, jsf run in weblogic 8.1 ? I'm some problem to understand this because i've build an application but the log give me two exception:

1. a servlet exception (generic)
2.<14-nov-2006 8.59.14 CET> <Warning> <HTTP> <BEA-101162> <User defined listener o
rg.apache.myfaces.webapp.StartupServletContextListener failed: java.lang.NoClass
DefFoundError: javax/servlet/jsp/el/ELException.>

Thanks for help..

Hi Pino,

If you use MyFaces with Weblogic 8.1 you must include servlet-api.jar and jsp-api.jar (e.g. from tomcat 5 library) into the weblogic classpath.
Furthermore, put the following snippet into your web deployment descriptor:

    
    <servlet>
      <servlet-name>Faces Servlet</servlet-name>
      <servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class>
      <load-on-startup>1</load-on-startup>
    </servlet>

This patch works with WL8.1sp2 and Myfaces 1.1.1. I don't know if things have changed in newer releases.

why? THANKS FOR REPLY ..

I cannot tell you for sure what went wrong here. From the stack track I take that weblogic cannot find an ADF-library. I recommend checking your classpath.

i've seen on internet that the problem can happen because all ServletContextListener are loaded after the servlet 'javax.faces.webapp.FacesServlet' and i've applied a solution that don't running!

Hi.

The missing class ELException belongs to the JSP API. From which tomcat version did you take servlet-api.jar and jsp-api.jar? Try 5.0.x.
