regarding integrating R into Web-applications

Question

I have been using R to perform statistical analysis. I would like to know how to integrate the R-based analysis into a Web-application. For instance, let user submit the data, and invoke R to perform related analysis on the back-end.

The possible Web-application will be written in Java. What confuses me is the integration process.

I am new to Web-application, so any suggestions, tutorials, and examples will be highly-appreciated.

Answer 2

To run R code inside Java, I recommend to use the JRI library. To get started with java web applications, you should read a tutorial such as Oracle's "Get started with Web Applications".
