Disabling Faces Error Handling

[rbaumhof <ra...@web.de>]

Hello,

we are using MyFaces for building the web pages. If we display a list or
listbox (method with return type public List<SelectIem> getSomething())
there may happen an error within the ejb container. In this case faces shows
an own error page. At the bottom of the page is a link where the tailoring
of this default behaviour is described
(http://wiki.apache.org/myfaces/Handling_Server_Errors). Especially two
approaches are interesting. One describes how to write an own error handler,
the other describes how to use tomahawk for installing a customized error
handler. Unfortunately both approaches don't work. The error message is
always "java.lang.class not found error". In the case of the tomahawk
approach this is clear because the class
(org.apache.myfaces.tomahawk.util.ErrorRedirectJSFPageHandler) which is
described in the tutorial
(http://issues.apache.org/jira/browse/TOMAHAWK-1297) does not exist in the
tomahawk jar file (tomahawk-1.1.6.jar). 

Any suggestions where one should place the self written error handler class.
Actually it is in WEB-INF/classes.

thanks for your help in advance
Ralf

Hi Pavel,

no, i did not find a solution yet now. I have worked around the problem by
configuring error pages 
in web.xml. Unfortunately this does not work for error code 500. But at the
moment i could solve all problems where error code 500 was sent, so in most
cases it's now working and the user never sees a tomcat or faces generated
error page.

Hello Ralf,

I think the location is right and I expect the same behaviour as you. I'm
researching the same issue and for now I know that:
- when I bundle my own version of MyFaces in WEB-INF/lib directory
- hidden-classes org.apache.myfaces and javax.faces in geronimo-web.xml

all works as expected and is described in Wiki.

I don't know how to specify webapp deployment descriptor when I want to use
server bundled version of MyFaces (classloading problem).

Have you resolved problem with your own ErrorHandler implementation?

Thx for reply

Pavel
