我们正在尝试在Tomcat 7上部署ActiveMQ Web Console 5.6（7.0.29精确地说是针对Java1.7.0_07）。

手动部署web控制台war后，我们修改了http://activemq.apache.org/web-console.html的说明如下：

• 我们添加了actiemq-all-5.6.0.jar、jetty. util.6.1.12.jar和comons-loging-1.1.jar到${cataline_home}/lib目录
• 我们在catalina. bat中添加了以下内容：CATALINA_OPTS=-Xms4m-Xmx256m-Dweb控制台.type=properties-Dweb控制台.jms.url=tcp://localhost:61616-Dweb控制台.jmx.url=service：jmx：rmi：///jndi/rmi://localhost:1099/jmxrmi-Dcom.sun.management.jmxRemote-Dcom.sun.management.jmxRemote.port=7777-Dcom.sun.management.jmxRemote.ssl=false-Dcom.sun.management.jmxRemote.验证=false

Tomcat然后愉快地启动，我们可以看到Web控制台的登陆页面（http://localhost:8080/activemq-web-console-5.6.0/），但是当我们尝试访问时：

http://localhost:8080/activemq-web-console-5.6.0/queueGraph.jsp 

我们得到以下堆栈跟踪：

外面有人能帮忙吗？

请注意：完全相同的步骤，但与Tomcat 6.0.35工作正常。

TIA
