Problem in Weld and Seam 3 in Tomcat 6
I create a serlvet based project from the weld servlet archetype.
And updated the dependencies to the latest version(weld 1.1.1Final), it works well.
But when I tried to added the Seam3 dependencies, and run application via mvn tomcat:run
, I encountered a exception.
严重: Exception sending context initialized event to listener instance of class org.jboss.weld.environment.servlet.Listener java.lang.RuntimeException: Error instantiating class org.jboss.seam.xml.bootstr ap.XmlExtension at org.jboss.weld.util.ServiceLoader.prepareInstance(ServiceLoader.java: 282) at org.jboss.weld.util.ServiceLoader.loadService(ServiceLoader.java:238) at org.jboss.weld.util.ServiceLoader.loadServiceFile(ServiceLoader.java: 194) at org.jboss.weld.util.ServiceLoader.reload(ServiceLoader.java:157) at org.jboss.weld.util.ServiceLoader.iterator(ServiceLoader.java:346) at org.jboss.weld.bootstrap.ExtensionBeanDeployer.addExtensions(Extensio nBeanDeployer.java:93) at org.jboss.weld.bootstrap.WeldBootstrap.startInitialization(WeldBootst rap.java:340) at org.jboss.weld.environment.servlet.Listener.contextInitialized(Listen er.java:170) at org.apache.catalina.core.StandardContext.listenerStart(StandardContex t.java:4135) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4 630) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardHost.start(StandardHost.java:785) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:445 ) at org.apache.catalina.startup.Embedded.start(Embedded.java:825) at org.codehaus.mojo.tomcat.AbstractRunMojo.startContainer(AbstractRunMo jo.java:558) at org.codehaus.mojo.tomcat.AbstractRunMojo.execute(AbstractRunMojo.java :255) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(Default BuildPluginManager.java:101) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor .java:209) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor .java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor
but when I remove the weld listener in web.xml, and browsed the home page, and another exception in the page.

Some of my configuration.
web.xml
<servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- Tell the context which URLs to process with JSF --> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.jsf</url-pattern> </servlet-mapping> <!-- This section is optional. We are allowing index.jsf to handle the root URL (i.e., /). --> <welcome-file-list> <!-- Add additional files here, if desired, for example: <welcome-file>index.html</welcome-file> --> <welcome-file>index.jsf</welcome-file> </welcome-file-list> <listener> <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class> </listener> <resource-env-ref> <description>Object factory for the CDI Bean Manager</description> <resource-env-ref-name>BeanManager</resource-env-ref-name> <resource-env-ref-type>javax.enterprise.inject.spi.BeanManager</resource-env-ref-type> </resource-env-ref>
And beans.xml content
<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:s="urn:java:ee" xmlns:t="urn:java:org.jboss.seam.transaction" xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee http://docs.jboss.org/cdi/beans_1_0.xsd"> <interceptors> <class>org.jboss.seam.transaction.TransactionInterceptor</class> </interceptors> <t:SeSynchronizations> <s:modifies/> </t:SeSynchronizations> <t:EntityTransaction> <s:modifies /> </t:EntityTransaction> </beans>
And the seam3 dependencies added in pom.
