Hello -
I created a web-app with
JSF framework initially and got it successfully running on
Tomcat 5.5.9. The jsf related jars used here were - jsf-api.jar and jsf-impl.jar. Later the same application I tried converting into a Portlet by including the portlet.xml and making modification to web.xml. Replaced the above jars with myfaces-1.0.9.jar and myfaces-jsf-api-1.0.9.jar to have the JSf-portlet bridging done. This I then deployed on to JetSpeed 2 and after some trials could get it running successfully.
Now the same war file (with modification in web.xml to remove entry specific to JetSpeed) when deployed on to Weblogic 8 is giving me the following exception -
java.lang.ClassCastException at javax.faces.webapp.UIComponentTag.setupResponseWriter(UIComponentTag.java:641) at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:244) at org.apache.myfaces.taglib.core.ViewTag.doStartTag My app web.xml looks like this when it is a simple JSF web-app. <context-param>

web.xml after the project was imported and auto fitted by Weblogic 8, is only modified to exclude the JetSpeed related entries. If anyone can hint on what could be problem? Or any link that could give some information anything in line would be great.
If this is not the right forum to raise the issue, please let me know.
many thanks
ps:I'm new to JSF and portlets & currently trying out stunts with these technologies. My
test Portal servers are JetSpeed 2 and WebLogic 8.
