Liferay and ICEFaces Integration

I was trying to create ICEFaces portlet in Liferay. I was using Liferay 4.3.2. I downalod the sample portlet available from http://sourceforge.net/project/showfiles.php?group_id=49260 (file: sample-icefaces-sun-portlet-4.3.2.1.war). The war was working in tomcat 5.5. But to make it work with liferay-jboss-bundled I had to modify the library jar files. Due to conflict of the classes I had to remove following jar files:

• el-api.jar
• jsf-api.jar
• jsf-impl.jat
• log4j.jar

I hope I am not missing anything.
