错误现象:

解决办法:

编辑D:\jboss-4.0.5.GA\server\default\deploy\jbossweb-tomcat55.sar\META-INF\jboss-service.xml文件,修改Java2ClassLoadingCompliance和UseJBossWebLoader为true,即:

      <attribute name="Java2ClassLoadingCompliance">true</attribute>
      <attribute name="UseJBossWebLoader">true</attribute>

重启服务器即可.
