WebSphere in the Clouds with Rubies

Well, with Ruby anyway, at least as a scripting framework.

 Learned two excellent principles for getting WebSphere to work well in on-demand virtualization environments like the Amazon EC2 cloud:

Installing WINE in 64-bit Ubuntu

Since moving to 64-bit I've found the odd problem but nothing prohibitive. So it is with a difficulty in running some Windows applications in 32-bit versions of Wine, including the excellent Crossover Office The problems seem to be in file system access ... when you attempt a save from the Windows program you exit without error.

Computing in the (EC2) Clouds

I'm changing employers, and before I did I visited the new folks to get a feeling for what I was getting into. Turns out I came away with more than I bargained for ... Danny, a client had asked Tom, a developer to look into the Amazon web services, and Tom's summary, while old news to some of you, made a major shift in how I'm thinking about system deployment.

PHP/JavaBridge and WebSphere 4: Using the Compiled JavaBridge Front End

JavaBridge is fairly well supported on a mailing list at  php-java-bridge-users@lists.sourceforge.net -- the archives are available here.  Jost Böekemeier, the creator and lead developer monitors the list and frequently answers questions; in response to some of my queries on architecture and performance he made a statement that seems obvious now, but really made the penny drop for me:

Hi,

The php_java.dll or java.so (Unix) is the Java.inc, compiled to native code, yes.


So ... the mystery is solved.  The dll for windows and .so library for linux are simply compiled front ends for specific platforms; the speed improvement is the usual improvement one sees for compiled code.

PHP/JavaBridge and WebSphere 3: Adding Drupal to the Mix

The steps to integrate PHP and Drupal with Apache are well-documented in an IBM tutorial for Windows and Linux.  You'll need to register for the IBM website to view it, but it's well worth the few minutes it takes.  Note that these installation tutorials are part of a very good larger series on Drupal from IBM, available here as an RSS feed.

Before you begin the tutorial I'd suggest you back up your Apache configuration, in case something breaks in the course of Drupal and PHP integration.

PHP/JavaBridge and WebSphere 2: Integrating Apache and WebSphere with the Bridge

First steps are here

Introducing the Web Server and Plug-In

In WebSphere a separate application called the Web Server Plug-In mediates between the HTTP Server and the WAS Application server, determining which URL's seen by the HTTP Server are handled directly and which are passed to the WAS application server for processing in JEE.

PHP/JavaBridge and WebSphere 1: Installing JavaBridge in WAS 6.1

Early Days - PHP JavaBridge and WebSphere 6.1 I'm interested in integrating some quality PHP applications like Drupal with the J2EE/JEE enterprise applications I love so well in order to broaden collaborative offerings. The key barrier that I see is security integration, and the key to that session integration.

PDT PHP tools and IBM Rational RSA ... Time to Give Up. Sort of.

Well, I ran this issue to ground, and at the end of the day, while the links plugin strategy works like a charm, the web tools plugins that can work with PDT 0.7 cannot work with RSA due to a early conflict with a number of RSA's plugins, including JSF.

I submitted this situation as an eclipse bug, but (and who could blame them) the web tools maintainers pointed out that compatibility with IBM's V3.2 plug-in's was hardly their problem, and the PDT maintainers pointed out that a 0.7 release (needed because all the IBM tools target a 3.2 eclipse) is hardly theirs.

Using Links to Install PHP Development Tools (PDT) in Rational Application Developer / Eclipse

Summary

This post is mainly of interest to developers who use Eclipse, especially IBM/Rational Branded versions.

The web-based software updates/find and install features of Eclipse have significant problems resolving dependencies for additional plugins, at least in the IBM branded versions. You can work around these difficulties and bring more order and control to your installation by using the links based mechanism described below

AideRSS ... A Great Start at Predictive News Reading

I've been doing some work recently on predictive newsreading ... adapting open source software to give people a customized daily newspaper of online news tailored to their interests. As a big fan of citizen journalism I've been focusing on blogs as news sources, where RSS feeds are ubiquitous.

A colleague showed me the AideRSS release today, which looks like a great start in prediction!
