I have Java 1.6.0_03. I can build Seam 2.0.0CR2 without difficulty (Maven 2 fires right up and seems to pull everything). I can then "cd examples/blog" and "ant tomcat.deploy". I take jboss-seam-blog.war from the place it puts it, and drop it into my actual Tomcat 5.5.12 webapps directory, and launch Tomcat. And boom: | [main ] 2007-10-29 22:38:37,515 INFO HostConfig:783 - Deploying web application archive jboss-seam-blog.war | [main ] 2007-10-29 22:38:37,968 ERROR [/jboss-seam-blog]:3643 - Error configuring application listener of class com.sun.faces.config.ConfigureListener | java.lang.NoClassDefFoundError: javax/el/CompositeELResolver | at java.lang.Class.getDeclaredConstructors0(Native Method) | at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389) | at java.lang.Class.getConstructor0(Class.java:2699) | at java.lang.Class.newInstance0(Class.java:326) | at java.lang.Class.newInstance(Class.java:308) | at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3641) | at org.apache.catalina.core.StandardContext.start(StandardContext.java:4127) | at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:759) | at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:739) | at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:524) | at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:804) | at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:693) | at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:472) | at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1118) | at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:310) | at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) | at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1020) | at org.apache.catalina.core.StandardHost.start(StandardHost.java:718) | at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1012) | at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:442) | at org.apache.catalina.core.StandardService.start(StandardService.java:450) | at org.apache.catalina.core.StandardServer.start(StandardServer.java:680) | at org.apache.catalina.startup.Catalina.start(Catalina.java:536) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:597) | at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:275) | at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) | [main ] 2007-10-29 22:38:38,015 ERROR [/jboss-seam-blog]:3650 - Skipped installing a | pplication listeners due to previous error(s) | [main ] 2007-10-29 22:38:38,015 ERROR StandardContext:4128 - Error listenerStart | [main ] 2007-10-29 22:38:38,015 ERROR StandardContext:4153 - Context [/jboss-seam | -blog] startup failed due to previous errors | | | | | According to good old FindClass, the missing class is in el-api.jar and jsp-api.jar, neither of which are built into jboss-seam-blog.war.
