我打算将BPEL用于项目，我尝试通过创建一个简单的示例（我已经找到this和this）并使用发布中提供的示例来开始学习。但是，我无法做任何工作，也不是我创建的小例子和提供的例子。 我通过将其war文件放在 / var / lib / tomcat / webapps 目录中来安装Apache Ode。我已将示例放在 / var / lib / tomcat / webapps / ode / WEB-INF / processes 文件夹和 tomcat / webapps /中的 bin 文件夹中赋。当我尝试按照自述文件中的说明调用示例时：
sendsoap http://localhost:8080/ode/processes/helloWorld testRequest.soap
我收到错误：
Error: Could not find or load main class org.apache.ode.tools.sendsoap.cline.HttpSoapSender
关于浏览器界面，ODE主页加载（http://localhost:8080/ode/#/）但不识别任何服务或进程。
我已根据@ Sathwik在下面评论中的说明重新安装了ODE。当重新启动tomcat时，我得到了关于catalina日志的以下信息（我只包含了关于ode的行），它警告了可能的内存泄漏：
19-Jan-2018 10:38:43.972 WARNING [localhost-startStop-2] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesJdbc The web application [ode] registered the JDBC driver [org.apache.derby.jdbc.AutoloadedDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
19-Jan-2018 10:38:43.973 WARNING [localhost-startStop-2] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [ode] appears to have started a thread named [Timer-1] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:
java.lang.Object.wait(Native Method)
java.util.TimerThread.mainLoop(Timer.java:552)

19-Jan-2018 10:38:43.973 SEVERE [localhost-startStop-2] org.apache.catalina.loader.WebappClassLoaderBase.checkThreadLocalMapForLeaks The web application [ode] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@409a18d]) and a value of type [org.apache.derby.iapi.services.context.ContextManager] (value [org.apache.derby.iapi.services.context.ContextManager@33b194b]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

我检查了我的旧日志（当我在这个问题中遇到问题但尚未重新安装时）并且输出结果不同：
18-Jan-2018 16:23:51.645 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deploying web application directory [/var/lib/tomcat8/webapps/ode]

我正在使用ODE 1.3.7，tomcat8和Ubuntu 17.10。 示例的位置或ODE依赖性是否存在问题？ 应该怎么做才能避免日志中提到的内存泄漏？ 至少应该按照教程的建议在Web界面中列出示例流程吗？
