Mohamed Thowbick commented on MYFACES-1693:
-------------------------------------------
I am trying to use myfaces-1.2.2 with weblogic 9.2 in windows XP. I have done
everthing as stated here to configure myfaces 1.2.2 for JSP 2.1 compliance as
optional. But when i tried to access the jsf page of my applicaion which uses
tree menu control, i got the following error in my log and its showing blank
page.
11:37:41,537 ERROR _ErrorPageWriter:350 - An exception occurred
javax.faces.FacesException: Failed to compile JSP
/jsp/reports/emptyReportFrame.jsp
emptyReportFrame.jsp:10:24: No conversion available for the type
"javax.el.ValueExpression".
<h:outputText value="<=== Please select a Report on
the left. Note: Only reports marked with (*) are currently available"/>
^-------------------------------------------------------------------------------------------------------^
Did anyone faced this before? Did i miss out anything.
Please help me to get out of this.

> Myfaces 1.2.0 requires JSP 2.1 to be present. Otherwise the
> StartupServletContextListener fails with this error:
> Exception sending context initialized event to listener instance of class
> org.apache.myfaces.webapp.StartupServletContextListener
> java.lang.NoSuchMethodError:
> javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;
> at
> org.apache.myfaces.webapp.DefaultFacesInitializer.initFaces(DefaultFacesInitializer.java:102)
> at
> org.apache.myfaces.webapp.StartupServletContextListener.contextInitialized(StartupServletContextListener.java:57)
>
> JSP version 2.1 or better JSP in general should be an optional dependency,
> like discussed here and implemented in Sun RI too:
> http://www.nabble.com/Does-MyFaces-1.2-require-JSP-2.1--tf4112432.html#a11693501
> Use cases:
> - Run Myfaces 1.2.0 in JEE 1.4 environment (Tomcat 5.x).
> - Easier setup and smaller distributions when running Myfaces in an embedded
> servlet container (jetty) with facelets. For example I'm using jetty for
> junit tests. I haven't found a working setup which solves the jsp problems.
