I tried the example above without using maven

my libraries are

antlr-2.7.6.jar cdi-api.jar com.springsource.javax.servlet.jsp.jstl-1.2.0.jar com.springsource.org.hsqldb-1.8.0.9.jar commons-beanutils-1.7.0.jar commons-codec-1.3.jar commons-collections-3.1.jar commons-digester-1.8.jar commons-discovery-0.4.jar commons-logging-1.1.1.jar dom4j-1.6.1.jar hibernate-jpa-2.0-api-1.0.0.Final.jar hibernate3.jar javassist-3.9.0.GA.jar jsf-api.jar jsf-impl.jar jta-1.1.jar slf4j-api-1.5.8.jar weld-api.jar weld-core.jar weld-servlet-int.jar weld-servlet.jar weld-spi.jar weld-tomcat-support.jar

when i access the page http://localhost:8080/weldTest/index.jsf

i get the following error
