accessing JDK information from .jsp page

[Sara Watson]

I want to display the JDK version that is being used by my web server. How can I access that information from my .jsp page? What object/method call will give me that info?
Thanks for your help,
Sara

The following code will print out on your jsp page, a bunch of properties:

<%    Properties prop = System.getProperties();
      Enumeration enumer = prop.propertyNames();
      while (enumer.hasMoreElements()) {
         String theProp = (String)enumer.nextElement();
%>       <b><%= theProp  %> </b> ==> <%= prop.getProperty(theProp)%> <br />
<%
      }
%>  

That prints out a bunch, but I found a property called "java.version" that may be what you're looking for.

There is also a property called "java.runtime.version". Print them all out on a test page and see what you need.

Thanks Mike. That's just what I needed.
