本文介绍了解决Apache CXF客户端在调用服务时遇到411 Length Required错误的方法，通过设置HTTP客户端策略避免使用分块传输编码。

错误信息记录：

通过打出客户端cxf的报文信息：

lighttpd 返回"411 Length require"字样的错误。同时，在lighttpd的err日志里面，有如下的错误信息
2007-09-27 16:17:39: (request.c.1110) POST-request, but content-length
missing -> 411

结果确定原因是cxf客户端调用时缺少了content-length属性，需要进行如下配置：

Client client = ClientProxy.getClient(greeter);
HTTPConduit http = (HTTPConduit) client.getConduit();
HTTPClientPolicy httpClientPolicy = http.getClient();
httpClientPolicy.setAllowChunking(false);

如果是xml可以采用以下配置：
