[ome-users] insight.jnlp and Nginx redirection

[Mark Woodbridge]

When we originally wrote the jnlp files we served them as JSPs, thus 
removing the hardcoded URLs but adding a dependency on a servlet 
container (example below). I guess the same approach could be achieved 
using Django but I didn't attempt that.

Mark.



<%@ page contentType="application/x-java-jnlp-file" %>
<?xml version="1.0" encoding="utf-8"?>
<jnlp
   codebase="<%= request.getRequestURL().substring(0, 
request.getRequestURL().lastIndexOf("/") + 1) %>"
   href="<%= 
request.getRequestURL().substring(request.getRequestURL().lastIndexOf("/") 
+ 1) %>">
   ...
   <resources>
     <j2se version="1.5.0+" max-heap-size="256m"/>
     <jar href="omero.insight.jar"/>
     <jar href="config.jar"/>
     <jar href="libs/xalan-2.7.1.jar"/>
     ...
   </resources>
   <application-desc/>
</jnlp>
