Error on upgrading to myfaces1.2.8
Hi,
I am trying to upgrade to myfaces 1.2.8 from myfaces 1.1.5 on weblogic
server 10.3. I am trying to display a simple jsf page .
<%@ page session="false" contentType="text/html;charset=utf-8"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<html>
<f:view>
<f:verbatim>
<body>
<h:form id="form">
<h:panelGrid id="grid" columns="1">
<h:outputLink value="helloWorld.jsf">
<h:outputText value="HelloWorld" />
</h:outputLink>
</h:panelGrid>
</h:form>
</body>
</f:verbatim>
</f:view>
</html>
I am getting the following stack trace:
java.lang.ClassCastException: java.lang.String cannot be cast to

Hi ,
I was able to resolve the problem.
I had initialized JSPTilesViewHandler instead of JSPTwoTilesViewHandler in
faces-config.xml. On correcting it , I am able to view my page.

The blank page happens usually if you mix two jsp versions together
(or two el versions)

Re: Error on upgrading to myfaces1.2.8
Posted by Geetika Srivastava <ge...@tcs.com>.
Hi Jacob,
Thanks for the reply .
I cleared the cache and tried running the application.
I am not getting any error but no output is being displayed i.e I am
getting a blank .
Moreover the complete page is getting printed in the logs.
Please let me know if I am missing out on something.

Re: Error on upgrading to myfaces1.2.8

Hi again,
I did some research about this problem and found some similar issues in
various different projects and frameworks (e.g. in primefaces [1]). The
real
problem seems to come from the tag library descriptor (.tld) files.
In MyFaces 1.1.x the entry for the value attribute of h:commandButton
looks
like this:
<attribute>
<name>value</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
<type>java.lang.String</type>
<description><![CDATA[The initial value of this
component.]]></description>
</attribute>
It specifies a type of java.lang.String, because Unified EL was not
included
in JSF 1.1 and thus JSF 1.1 resolved the expressions itself. In MyFaces
1.2.x, however, the entry looks like this:
<attribute>
<description><![CDATA[The text to display to the user for this
command component.]]></description>
<name>value</name>
<deferred-value>
<type>java.lang.Object</type>
</deferred-value>
</attribute>
Unified Expression Language is used in JSF 1.2 and thus the entry must not
specifiy a normal type, but a type inside a deferred-value element. With
this entry the web container knows that it has to create a ValueExpression
for the given attribute.
My guess now is that your weblogic server somehow uses the "old" .tld
files
from MyFaces 1.1.x with your application that uses MyFaces 1.2.x and thus
the Unified EL integration does not work correctly. However I don't know
why
this could be the case. Maybe a caching issue. You could try to clean up
your server and restart it. Maybe it will work then.
I really hope this will help you!

Jakob

Re: Error on upgrading to myfaces1.2.8
Posted by Jakob Korherr <ja...@gmail.com>.
Hi,
Seems like a Expression Language problem. The Servlet (which is
automatically created by Weblogic) that handles the JSP page internally
seems to expect a ValueExpression but it (only) gets a String. So either
something from weblogic is missing here (or does not work correctly) that
would create the ValueExpression out of the (Expression-)String or weblogic
handles plain String entries in ValueExpression-attributes wrong.
You could try to push weblogic to create a ValueExpression for the two value
attributes in your sample page by adding #{' at the begin and '} at the end
of the String value. So your page should look something like this (some
parts are cut for clarity):
<h:outputLink value="#{'helloWorld.jsf'}">
<h:outputText value="#{'HelloWorld'}" />
</h:outputLink>
This will maybe work, but you should not have to do it this way!
Regards,
Jakob
