getAllDefinitions Proton CEP中的异常

我已经在CentOS和Tomcat 7上的自己的服务器上部署了Proton CEP .

致电 /ProtonOnWebServerAdmin/resources/definitions

失败的例外是：

其他API工作正常 . 例如：

PUT ProtonOnWebServerAdmin/resources/instances/ProtonOnWebServer 返回200 OK

我还可以使用以下命令成功更改正在运行的实例的阶段： ProtonOnWebServerAdmin/resources/instances/ProtonOnWebServer

此外，定义应该是的文件夹是空的 . 在 ProtonAdmin.properties 中，它被配置为 definitions-repository= / home / xmarine / ProtonDefinitions`

该文件夹的权限是：

[xmarine@app-fiware ProtonOnWebServerAdmin]$ ls -al /home/xmarine/ProtonDefinitions/
total 4
drwxrwxr-x 2 tomcat  tomcat     6 dec  8 12:18 .
drwx------ 7 xmarine xmarine 4096 dec 14 14:40 ..

你能帮帮我解决这个问题吗？
