JSF - using Myfaces 1.1.4 - Exception from ELResolverInitPhaseListener

[Former Member]

Hi,

We are using Myfaces 1.1.4 and tomahawk from 1.1.2-snapshot.

I can bring up this application in JBoss, welogic, websphere.

The .jar files are bundled in .ear file under WEB-INF/lib folder. Why am I seeing this exception.

Is this classpath issue? If so, how do I fix this.

Please let me know.

thanks

Hello,

the JSF framework is now supplied by the platform as described in Java EE 5 specification, taking precedence over application supplied libraries. Therefore the app is picking up the classes of the RI. It is not possible or at least not trivial to replace the implementation of JSF framework, but it shouldn't be necessary as JSF 1.2 is fully backwards compatible. In additon, by effectivly replacing the engine supplied implementation a number of features such as resource injection are going to be lost.

Best Regards

Thanks for your response.

In one of the threads on the same issue

pointed to this blog - which should resolve classloading issue, would that fix this issue as well??

Can some one comment on this.

Hello,

In the blog

/people/community.user/blog/2007/05/21/using-hibernate-in-sap-netweaver-composition-environment

They have written that the application is Java EE 5 version or higher.

I have installed Netweaver CE 7.1 version and my jdk is 1.5.

How do I verify this information? I generate .ear using ANT task.

my application.xml looks like this -

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.3//EN" "http://java.sun.com/dtd/application_1_3.dtd">

<application id="Application_ID">

<display-name>abcd-TPRO</display-name>

<module id="TCAPIEjbModule">

<ejb>lib/TCAPI.jar</ejb>

</module>

<module id="WebModule_1060806603084">

<web>

<web-uri>abcd.war</web-uri>

<context-root>abcd-TPRO</context-root>

</web>

</module>

</application>

I am trying to get the application up, using myfaces implementation of JSF instead of the Sun implementation.

I included application-service.xml under META-INF folder.

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE application-service SYSTEM "application-service.dtd" >

<application-service>

</application-service>

Also, copied jar files to lib folder under .ear.

I have set the option Define-Heavy-Resources to true and restarted the machine etc.,

Any comments or suggestions.

thanks

I am using NetWeaver CE 7.1.

Can someone tell me why NetWeaver is picking up Sun implemenation of JSF instead of the one specified in WEB-INF/lib.

How do I fix this?

thanks
