anyone has encountered java ssDefFoundError while deploy the idp.war file?

[Wang, Holly]

Hi,

I have moved the idp.war file under tomcat/webapps folder, tomcat had hard time to deploy this war file. I got following error. 

The tomcat version is 6.0.29,
JAVA_HOME is java-1.6.0-openjdk-1.6.0.0.x86_64


org.apache.catalina.core.StandardContext listenerStart
SEVERE: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener
java.lang.NoClassDefFoundError: javax/servlet/ServletContextListener

Thanks

Holly
