目前我们的应用程序在jboss上运行没有任何问题。当前堆栈 - jbpm 6.1.0.Final，jboss 7，jdk1.7.0_45，oracle数据库 我们使用jbpm api来管理进程状态。
我们正在升级我们的平台，并希望继续使用tomcat。我试图在新堆栈上移植现有的应用程序 Tomcat 8.0.23，Oracle JRE 1.8.0_51，jbpm 6.1.0.Final＆amp; oracle数据库
已按照以下参考资料中列出的说明进行操作。 参考文献： https://github.com/droolsjbpm/kie-wb-distributions/tree/master/kie-wb/kie-wb-distribution-wars/src/main/assembly/tomcat7
我收到以下错误，遇到了其他人面临的类似问题，但无法找到解决方法。 例如https://developer.jboss.org/message/865873#865873
由于以下错误，未部署应用程序。 你能建议吗。
