Java Feature: Putting a Face on Web Services and SOA
— Service-Oriented Architecture (SOA) is a hot topic among analysts, CIOs, and technology marketers, but the path from high-level architectural principles to programming a functioning, real-world service isn't always clear, especially since, in the end, you still need to create a clean user interface that's as flexible as the services it consumes.

Realtime Validation with Ajax

Greg Murray's Blog talks about Realtime Validation with Ajax with examples. With the same examples, he talks about Internationalization (i18n). He further says that Internationalization (i18n) is easy if we are using AJAX and Java. Both Java and JavaScript have i18n capabilities though it is not obvious how to use those capabilities are not from an i18n background.

JavaScript Recommendations for AJAX Component Writers
Author: Greg Murray

With AJAX there are many choices on how to use different aspects of JavaScript. This document proposes some recommendations for developers creating AJAX components with a focus on using JavaScript on the client and Java on the server. Many of these recommendations will carry over to other server-side technologies.

Hermes - JMS explorer

Hermes is a Swing application that allows you to interact with JMS providers. Hermes will work with any JMS enabled transport making it easy to browse or seach queues and topics, copy messages around and delete them. It fully integrates with JNDI letting you discover administered objects stored, create JMS sessions from the connection factories and use any destinations found. Many providers include a plugin that uses the native API to do non-JMS things like getting queue depths (and other statistics) or finding queue and topic names.

Awk with Java

Jawk is an Awk implementation written in Java. It also augments Awk
such that Awk scripts can access Java services, such as Threads,
Sockets, etc. Java 1.5 is required. Go to
http://www.sourceforge.net/projects/jawk to download the executable jar
file (jawk.jar).

Jawk is a combination of Awk and Java such that Awk scripts can utilize
Java services. That is, you may now contruct Awk scripts
- that have GUI front ends (via AWT or Swing).
- that can connect to servers via Sockets.
- that can utilize Java Security libraries.
- that can access databases via JDBC.
- that are multithreaded.

This is all achieved with a natural expansion of Awk syntax and
semantics, along with some additional keywords and operators. However,
the overall flavor of the scripts are still Awk.

Jawk implements as much of Awk as it can. I tried keeping it in line
with Awk standard set forth by The Open Group
(http://www.opengroup.org/onlinepubs/007908799/xcu/awk.html).

Go to http://jawk.sourceforge.net/ and click on Overview for more

Weblogic Web Services With Spring Framework

Blog by Matt Luce explains the problem faced to implement this with reference to Dev2Dev article.

Recently, I was trying to connect to a web service with the Spring Framework JaxRpcPortProxyFactoryBean. The web service and client code were generated with the weblogic servicegen and clientgen ant tasks respectively.

I found this example on the dev2dev site:

Unfortunately, it didn’t work for me. I spent almost an entire day trying to get it to work.
