Could not create Component: org.jboss.seam.core.validators

[mangelo123]

I am using JBoss Tools just to create a basic CRUD against a mySQL database with just a few tables. I am trying to deploy against Tomcat 6.x as a WAR only. I have checked all of my JAR dependencies and they are all correct. I see this exception when Tomcat starts. It says it cannon create the seam validators and then below it says it can't find the Hibernate Validator Class Validator.

Well, list all jars you have...

These jars are a result of a quick test of JBoss Tools under the latest Eclipse. I can build this application with no errors with JBoss Developer Studio deployed against JBoss 4.2.x AS.

Here are the JAR files for the Tomcat version using Eclipse:

I just tried a test with JBoss Developer Studio 1.1 with an Apache Tomcat 6 deployment. This time its complaining about javassist classes not found when it clearly is included in the build path.

What causes this?

[mangelo123]

I've just noticed that the jar files that I add as 'User Libraries' are not copied to the deployed project under the WEB-INF/lib directory. I know I've handled libraries like this in the past. Is this a bug?

It looks like you miss hibernate-validator.jar.
