Webstart https：在证书上使用服务器，而不在loadbalancer上 [英] Webstart https: works with server on certificate and not on loadbalancer
问题描述
我正在尝试为我的Java webstart应用程序创建https安全连接。我所做的只是配置我的Tomcat使用证书，我就完成了。我可以做
I'm trying to create a https secure connection for my Java webstart application. All I did was to configure my Tomcat to use a certificate and I was done. I could just do
https：// nsjns：8443 / abc / xyz.jnlp并且它下载了我的应用程序并且工作正常。
"https://nsjns:8443/abc/xyz.jnlp" and it downloaded my application and worked fine.
用于生产，我们购买了一个证书，这个证书保存在负载均衡器上，负载均衡器后面是实际的Web服务器。如果我使用浏览器，我可以看到服务器，并可以通过在浏览器中键入url来下载我的jnlp文件。但是，我无法使用Java webstart执行jnlp文件，因为我得到以下异常。
for production, we purchased a certificate and this cert was kept on the load balancer with the actual web server behind the load balancer. If I use the browser I can see the server and can download my jnlp file by typing the url in the browser. However, I cannot execute the jnlp file using Java webstart as I get the below exception.

它将我的网址从https解析为http。我是这个人的新手。请帮助我提出您的想法和建议。我缺少什么？
It is resolving my url from https to http. I'm new to all this. Please help me with your ideas and suggestions. What am I missing to do?
推荐答案
不太可能与您的证书有任何关系。尝试使用IP地址而不是webstart URL中的主机名。
Unlikely to have anything to do with your certificate. Try using the IP address instead of the hostname in the webstart URL.
您没有说明您正在运行webstart的平台，但是如果IP地址正常工作则启动webstart控制面板： javaws -viewer 并转到Java选项卡上的网络设置。假设它还没有这么说，请选择直接连接（即没有代理）并告诉我们之后是否有效。
You don't say what platform you are running webstart on, but if the IP address works then launch the webstart control panel: javaws -viewer and go to Network Settings on the Java tab. Assuming it doesn't already say so, select Direct Connection (i.e. no proxy) and tell us if it works after that.
