我正在开发webservice，我遇到如下问题：

请注意，JBoss Web / 2.1.10日志中提供了根本原因的完整堆栈跟踪 .
库是/jboss-eap-5.1/resteasy/lib/httpclient-4.0.jar"/ . 应用程序在Jboss 5 EAP服务器servlet容器上运行 . 它将作为war文件部署到服务器 .
因为缺少类 managedHttpClientConnectionFactory .
我的问题是我可以将httpclient-4.3.jar用于Jboss 5 EAP吗？因为这个类是可用的，或者有另一个解决方案来避免这个错误 . 有什么想法吗？
代码是：
Line number 443 : CloseableHttpClient client = HttpClients.createDefault();
try {
HttpPost postRequest = new HttpPost(attaActionContextListener
.getINSTANCE().getGsfsAddress());
// Set various attributes
// FileBody fileBody = new FileBody(file);
HttpEntity reqEntity = null; ...
行号197：parseServerResponse（uploadToGSFS（model，actionType），model）;第89行：返回doRequiredWorks（输入，ActionType.INSERT）;
