java - 出现错误 : Error parsing system bundle export statement when loading Fuse ESB

Question

我是 ESB 新手，正在努力让它继续下去。如果有人能指出我正确的方向来解决这个问题，我将不胜感激。

我的环境: 操作系统:Ubuntu 12.04(64位) JDK:1.7.0_51(64位) fuse :JBoss Fuse 6.0

我遇到以下异常:

**The log file has this message which keeps repeating:**

感谢我能得到的任何帮助。非常感谢。

当使用 org.apache.karaf.main.SimpleFileLock 来实现简单的主从故障转移部署时，就会发生这种情况。更多详情可查看here .

如果另一个 FUSE ESB 实例正在运行，则第二个启动的实例将等待，直到第一个进程停止。如果您停止第一个实例，第二个实例将启动并获得锁定，并且日志条目将消失。

主实例和从实例必须引用文件系统中的相同锁定文件。如果由于主服务器和从服务器位于不同的主机上而无法做到这一点，则可以使用 org.apache.karaf.main.DefaultJDBCLock 。
