Using Java to write scripts - executing JavaScript from a server-side Java class file in version 1.5

I receive three different types of GET requests from a mobile device to a class file on my web application. Since the mobile device does not provide any cookies, the log file only captures:

in.ter.nal.ip   ser.ver.i.p:port    2009-06-05  09:14:44    GET /applicationname/mobiledevicexml    reqtype=login&userid=xx###  200 87  -   MercuryMobile/1.0 CFNetwork/342.1 Darwin/9.4.1  cookieArrayLength=0;

If I am able to initiate javascript within my class file and create a javascript function call to urchinTracker() from within it, I can replace the redundant cookieArrayLength=0; with some valuable data that can be read by urchin for analytics reports based on the log file. We have been exploring scripting in Java with Rhino; Safari Bookshelf includes:

Scripting in JavaTM: Languages, Frameworks, and Patterns

which has allowed us to demonstrate that we can execute JavaScript within class files -- this functionality is readily available on Java 6.

Does anyone know of any resources for scripting with Rhino on Java 1.5 or 1.4?

Alternatively, any tips on running JavaScript using Java 1.5 would be greatly appreciated.

Answer №1

Introducing the Java Scripting API package in Java 6 has paved the way for a new scripting experience not available in earlier versions such as Java 1.4 or 5. With Java SE 6, a simplified version of Mozilla Rhino is integrated through javax.scripting as the default installation.

Interestingly, Mozilla Rhino itself does not necessarily require Java 6. According to their requirements page:

Recent versions of Rhino have only been tested with JDK 1.4 and above. However, older versions can support JDKs as early as 1.1.

This suggests that using Rhino may actually be feasible with Java 1.4. For reference, detailed documentation on Rhino can be found here. The Embedding Rhino section could provide insights into how scripting functions within the environment.

The absence of the javax.scripting package means direct interfacing with Rhino will rely on the Rhino API instead of the Java 6 native scripting API. Despite this, functionality between the two should remain relatively similar. Potential drawbacks may arise if future compatibility with Java 6 becomes necessary, potentially requiring a rewrite to utilize the Java Scripting API over supporting Rhino directly.

Answer №2

[I'm providing information in an answer format instead of a comment due to insufficient points for commenting directly on the question.]

Have you considered whether the urchinTracker() function is compatible with environments outside of a web browser? Just running the Rhino JavaScript interpreter may not suffice if the function relies on browser-specific objects like the Document Object Model (DOM) or XmlHttpRequest.

I recommend taking a closer look at the inner workings of the urchinTracker() function to confirm its compatibility with non-browser environments.

If you're looking to incorporate JavaScript into your server, Rhino is a great option to consider.
