在Tomcat6是开发的MyFaces，布署到WebLogic10中问题

在Tomcat6中开发的Web程序，用MyFaces1.2.5、ibatis开发，现将其布署到WebLogic10中：
步骤1:F:\bea\wlserver_10.0\server\bin\setWLSEnv.cmd 运行步骤2:
F:\bea\wlserver_10.0\server\bin>
java weblogic.Deployer -adminurl t3://localhost:7001 -user weblogic -password weblogic -deploy -library F:\bea\wlserver_10.0\common\deployable-libraries\jsf-1.2.war步骤3:新建 weblogic.xml，跟web.xml放在一起
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90">
<!--
Must define the library reference to jsf, otherwise jsf will not available in you webapp.
-->
<library-ref>
<library-name>jsf</library-name>
<specification-version>1.2</specification-version>
<implementation-version>1.2</implementation-version>
<exact-match>false</exact-match>
</library-ref></weblogic-web-app>
这三步骤已经做了，
然后启动出现下面异常，晕，找不到错误，请各位高手帮助：2009-3-5 17:10:21 com.sun.faces.lifecycle.LifecycleImpl phase
