Hi,
I am using RAD 6.0 and Websphere server 6.0 (jdk 1.4 and jvm 1.4) . I have
included Sun web developer pack standalone module(swdp-R1.jar) and
jsf-extensions-dynamic-faces.jar, jsf-extensions-flash.jar,
jsf-facelets-1.1.11a.jar, shale-remoting-1.0.3.jar,
jsf-extensions-common.jar and commons-logging-1.1.jar in my project library.
During starting of Websphere server , I am getting LInkage Error as below :-
-------------------------------------------------------------------------------

[4/3/07 16:20:20:300 EDT] 0000000a SystemErr R java.lang.LinkageError:
LinkageError while defining class:
com.sun.faces.extensions.avatar.event.DynaFacesContextListener
Could not be defined due to:
com/sun/faces/extensions/avatar/event/DynaFacesContextListener (Unsupported
major.minor version
49.0)
This is often caused by having a class defined at multiple
locations within the classloader hierarchy. Other potential causes
include compiling against an older or newer version of the class
that has an incompatible method signature.

In Class Loader of the Application, I have made the below settings :-
Class Loader Module : PARENT LAST
WAR Class loaderpolicy : Application
Pls let me know how to solve the above Error. MY JSF APplication is working
fine as a separate module. When i tried to add
the JSF Extensions (Jar files) for performing AJAX functionality, i am
getting the above Error.
Thanks
