Question

通过java（使用apache.commons.httpclient）发出出站请求时，我收到Permission denied。以下是jboss日志的根本原因：

我尝试使用curl在通过ssh连接到gear时获取页面，它运行正常并且能够正确获取数据。

我做错了什么？在发出请求时是否需要指定传出端口？

解决问题的最简单方法是将apache commons httpclient升级到版本4 +。

对我来说，版本4.3.5有效。这是maven条目：

<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.5</version>

获取数据时还需要进行一些更改。

其他方式，一个更复杂的方式，试图覆盖客户端中使用的套接字连接工厂。我没有尝试这种方式，但希望这个链接有所帮助： https://www.openshift.com/forums/openshift/commons-httpclient-permission-denied
