Startup fails: SeamListener NoClassDefFoundError for ServletContext
JBoss AS 4.0.5 w/EJB3
Seam 1.2.1
I have an app up and running with no problems. I made some changes to produce a new version and now I get this at startup: (I post entire stack trace below, almost wont let me do that)
2008-08-13 19:57:50,415 ERROR org.apache.catalina.core.ContainerBase. jboss.web.localhost./traneky Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
java.lang.NoClassDefFoundError: javax/servlet/ServletContext
at org.jboss.seam.util.Resources.getResourceAsStream(Resources.java:45)
at org.jboss.seam.init.Initialization.initComponentsFromXmlDocument(Initialization.java:127)
at org.jboss.seam.init.Initialization.create(Initialization.java:87)
at org.jboss.seam.servlet.SeamListener.contextInitialized(SeamListener.java:33)
Important points:
1) This exact version (ear file) that fails runs under Windows and RedHat Linux. The OS it fails under is CentOS Linux 5.
2) javax/servlet/ServletContext seams to be in default/lib/javax.servlet.jar. The exact same file is there in both the old successful app and the new. I am only changing the ear file (my app).
I don't know where to start looking. Suggestions?
