Question

我有以下配置：

在OpenShift Online上运行Tomcat 7档。我将Apache ODE部署为webapp并测试了一个完美运行的简单BPEL工作流程（Echo测试）。我在OpenShift上还有2个齿轮，它们都运行WildFly8服务器和一些Web服务。我为ODE创建了一个用于调用这些服务的工作流程。当我在运行Tomcat 7和Apache ODE的本地PC上测试工作流程时，它工作得很好。但是，在OpenShift上我有以下问题：

当ODE尝试调用远程Web服务时，它会告诉其Axis库创建一个套接字。从绑定套接字到＆＃34; localhost＆＃34;在OpenShift上是不允许的，我得到一个例外。我修改了org.apache.commons.httpclient.HttpConnection.open（）方法，将套接字绑定到我的齿轮的本地OpenShift IP而不是localhost，并摆脱了绑定异常。但是，远程网络服务似乎无法响应我的请求：

这篇文章给了我这个想法：https://www.openshift.com/forums/openshift/commons-httpclient-permission-denied

同样，在使用完全相同的网络服务在我的电脑上测试完全相同的工作流程时，它可以正常工作，因此WildFly8服务器和网络服务不是问题。

我很感激任何提示，我已经有近一个星期了...

Answer 1

我设法通过创建一个DIY盒式磁带并在其上安装最新版本的Tomcat 7来解决这个问题。我部署了ODE和我的工作流，得到了和以前一样的绑定错误，修改了Axis正在使用的apache-commons库，现在它正在顺利航行。

我不知道为什么它不能用我从OpenShift获得的Tomcat 7盒式磁带作为标准。

OpenShift上的Apache ODE调用远程Web服务超时
