查看Apache Tomcat上运行的HTML页面的java SSO身份验证

Question

我们有一个Web应用程序，它有HTML5页面，可以通过websocket连接到我们的服务器实时查看消息。要使websocket连接和显示图形正常工作，HTML5页面在显示之前需要SSO身份验证

已完成的内容

But for viewing that HTML 5 page we have no file based authentication to read the file with usernames and show a popup to enter username if it is matched then user will be able to see the HTML graphs page.This is not very good approach!!!

需要做什么

Now some type of SSO-Single Sign On authentication(not sure on what type of authentication our organization is currently using) is needed which will do some magical authentication on the back end and after that user would be able to see the HTML graphs page.

Currently the application is running on Apache Tomcat 6 and have couple of javascript files,CSS and one HTML page.Potential solution should be implemented in JAVA,can use any 3rd party API too.

提前谢谢
