How to use Rserve with JSP on Tomcat? (Windows 7)

Question

I am trying to write a web page using JSP which can talk to R via Rserve.

I have installed R and Rserve and both are running (I have checked in task manager).

What I need to to do now is make a connection between the two. I have found examples of JAVA but not JSP. I have tried editing the JAVA code to be used as JSP but that always gives me errors relating to this bit of code:

        try {
        RConnection c = new RConnection();
        double d[] = c.eval("rnorm(10)").asDoubles();
        org.rosuda.REngine.REXP x0 = c.eval("R.version.string");
        System.out.println(x0.asString());
    } catch (REngineException e) {

    }

I have been using the code from the answer on this question.

I am new to both JAVA and R so I am probably missing something really simple...

Thanks! Just ran it in Eclipse and it works perfect for Java! Is it possible to convert to code to JSP? – Dom Abbott Jun 13 '14 at 12:28
That my friend is a little to advanced for me, but I'm glad it worked :) – Du6e Jun 13 '14 at 12:30
No worries, thanks anyway! I guess I'll just have to go ahead and use java instead :) – Dom Abbott Jun 13 '14 at 12:31
Hey Dom, if it worked out for you, do mind giving me a check mark? I'm trying to get my rep up lol :p – Du6e Jun 13 '14 at 13:24
There you go, sorry I did try before but it said I couldn't mark it as answered yet. – Dom Abbott Jun 13 '14 at 13:37
