ArcGIS API for JS 打印功能报错

ArcGIS JS 3.x，使用printtask方法打印地图，但是会报错"Error executing tool. Export Web Map Job"，server上的日志报错则是

无法与服务器建立连接 (WinINet Error while using HTTPS security, 12029), URL = http:///arcgis/rest/services/ditu/MapServer/17

Error executing tool. Export Web Map Job ID: jbb275dbabcd848d6879fd5c199ec175c : Layer "ditu": Unable to connect to map server at http:///arcgis/rest/services/ditu/MapServer. Layer "ditu": Failed to create layer from service at http:///arcgis/rest/services/ditu/MapServer/17. Failed to execute (ExportWebMap). Failed to execute (Export Web Map).

想想应该是跨域的问题，尝试了代理的方法（https://github.com/Esri/resource-proxy/blob/master/Java/README.md）但不是特别明白，在配置完proxy.config和proxy.jsp文件之后，添加了如下代码

esri.config.defaults.io.proxyUrl= "http://192.168.0.207:9391/Java/proxy.jsp";



esri.config.defaults.io.alwaysUseProxy= false;

会报错，好像还是没解决跨域问题
