Can Seam 2.0.2sp1 apps run on Tomcat 5.5.9 with JBoss Embedded?

Question

I'm trying to run the Tomcat with JBoss Embedded jpa booking example. I run the build and deploy the war. I then get the following error:

ERROR [catalina.core.ContainerBase.[Catalina].[localhost].[/jboss-seam-jpa]] Error configuring application listener of class com.sun.faces.config.ConfigureListener
java.lang.NoClassDefFoundError: javax/el/CompositeELResolver

        at org.apache.catalina.core.StandardContext.start(StandardContext.java:4104

I find this class exists in el-api.jar which is not in the classpath. So I add el-api.jar to the WEB-INF/lib directory. I then get the following error:

INFO: JSF1048: PostConstruct/PreDestroy annotations present.  ManagedBeans methods marked with these annotations will have said annotations processed.

This library appears to be in el-ri.jar or JSP 2.1 jar. Am I doing something wrong? Is there a place that explains how to run seam applications on tomcat 5.5.x? Any help is greatly appreciated!

Answer 1

have you looked at the docs, there's also some pretty good info on the forums at www.seamframework.org and also the old forums at www.jboss.org.

Answer 2

I got this to work. I ran ant tomcat55 under the seam/examples/jpa example. This included the el-.jars needed. I then ran 'ant clean' and 'ant jboss-embeded' and manually copied in all of the el-.jars from the tomcat55 make. This got past my problem above. Now I'm able to start tomcat 5.5.9 with embedded JBoss. I can run the booking example now with no problems.
