Hessian Messaging: "Routing parameters are contained in the headers map. For example, Java's messaging service (JMS) defines a number of routing headers. These headers could be used for more sophisticated mail routing than point to point. Defining the routing headers is beyond the aim of this page. The important point to note is that the routing protocol is built on top of the Hessian messaging service which is built on Hessian. Hessian itself does not need to be complicated with the routing headers."

Implementing an Enterprise Service Bus in Java: "Using the open source Mule project, you can build a highly customized Enterprise Service Bus (ESB) that meets your specific needs." - COOL!
CodeHaus releases Mule 1.0, an open-source ESB: "Posted by Ross Mason in response to Message #167346 - Why not use a BPM Engine?
a) Mule resources can be managed by the AppServer
b) Mule can adopt the lifecycle of the app server
c) EJBs can send a receive events by subscribing of publishing to Mule endpoint URIs. This means the Mule ResourceAdapter acts as a TCP, SMTP, SSL, XMPP Resource Adapter inside the App Server. Really it's a Universal Resource Adapter."
1.) What are the differences between the Mule concept of a "Model" and a Business Process defined in BPEL.Potentially, not very much. As mentioned im my previous post, there will most likely be a BPEL model for Mule that defers all service management to BPEL an Mule would handle data interactions between the services.
2.) With the traction that BPEL standard is getting wouldn't it make more sense to define Business processes in a standardize language?It definitely makes sense to support the BPEL standard but not everyone wants or even can expose all their services using web services to be managed by BPEL. Mule can help here by providing an easy way of automatically exposing existing business object/services using soap endpoints. I think Mule and BPEL are complimentary in that Mule is concerned with the transport, routing and transformation of data where as BPEL defines the a way of working with services to build coherent business processes. The two would make a powerful combination.
3.) What are the pros and cons for using Mule(or any ESB) within an app server?Well above and beyond ESB capabilities for interfacing, delivering, transforming and routing data, Mule can be managed inside an AppServer. This means that -
a) Mule resources can be managed by the AppServer
b) Mule can adopt the lifecycle of the app server
c) EJBs can send a receive events by subscribing of publishing to Mule endpoint URIs. This means the Mule ResourceAdapter acts as a TCP, SMTP, SSL, XMPP Resource Adapter inside the App Server. Really it's a Universal Resource Adapter."

Richard Searle's Weblog : Weblog: "Codeless WebServices, even when returning JavaBeans" & "Spring is very elegant but the support for Web Services is a little disappointing. The standard examples all return a String, avoiding the nasty truth that returning a JavaBean is going to be messy. Spring requires you to subclass JaxRpcPortProxyFactoryBean and manually wire up the serialization classes. Those classes then have to written or generated using WSDL2Java. Essentially Spring only helps with the creation of the call to the WebService."

O'Reilly Radar > The Rise of Open Source Java: "Last year at OScon, I gave a presentation entitled What Book Sales Tell Us About the State of the Tech Industry. One of the conclusions I drew was that Java was in decline, as its share of total programming language book sales had dropped by five percentage points in the twelve months ending June 2004. Well, we just re-ran those numbers, and saw a startling reversal." - NICE

The Cubicle Jockey: When Will We Come Full Circle?: "Simon Brown also blogged about a new Web Services Tag library. What's the goal? To simplify the use of web services. I find this funny since we can generate a JSR for an easy to use tag library, yet we must still jump through hoops on the Java side to deploy and use web services. I realize that open source projects have made web services easier, but for pete's sake, why isn't this standardized in an easy to use API?"
IBM Systems Journal: Design and implementation of an enterprise grid: "Whereas the intraGrid GRAM-based Job Submission Portal only provides basic scheduling capabilities, a number of open-source projects and commercial grid offerings, such as the Condor (17) project, the UNI-CORE (18) project, the Open Portable Batch System (19) (OpenPBS), Platform's Load Sharing Facility (LSF), (20) IBM'S LoadLeveler *, (21) and Altair Engineering, Inc.'s PBS Pro **, (22) provide more extensive job scheduling capabilities (the GRAM service provides interfaces to these cluster-oriented schedulers and could be leveraged by the intraGrid project if there were cluster resources on intraGrid). Other commercial grid offerings, such as Platform Symphony **, (23) GridSystems' InnerGrid, (24) DataSynapse, Inc.'s GridServer **, (25) and United Devices' Grid MP **, (26) provide task-scheduling capabilities. In contrast to job schedulers, in order to take advantage of the finer grain distribution enabled by task schedulers, modifications to the application source code are usually required. The decision to use only open-source grid offerings or IBM internal technologies in the intraGrid project ruled out the use of any of these task schedulers. Work is now underway to add desktop grid capabilities for PCs based on Linux ** and Microsoft Windows ** onto intraGrid, using technologies developed by the Melody project (27) team." - PDF (from IBM Systems Journal - Vol. 43, No. 4, 2004 - Grid Computing)

Techie Musings » Blog Archive » Whither Autosys?: "Now, what really irks me is that there are few alternatives. I listed a few here [Techie Musings » Blog Archive » More on simple unix schedulers] some time ago, but Autosys is the Mother of Schedulers. It’s the de facto standard in the industry. But few of the alternatives are much better (I’ve experience with Espresso from Cybermation which was better in many regards, but had other significant problems of its own)... I’ve played with the concepts before, and a distributed cron was a suggestion from Robert Lefkowitz, publicised by Tim O’Reilly (Robert works at Optaros) as one of the missing Enterprise projects. Let me just say I’m giving it serious thought, because I really think Autosys is that bad. Call it an “itch” if you like, but system administrators and developers do deserve a better alternative, and I’m impassioned enough from my recent experiences (as the above hopefully testifies) to be seriously considering spending some time on this."

Raible Designs ~ We Build Web Apps: "AppFuse Light 1.0 - a.k.a. Equinox" & equinox: home: "Equinox uses Spring MVC and Hibernate by default. However, you can change your web framework to JSF, Struts, Tapestry or WebWork. You can also change your persistence framework to be iBATIS, JDO (JPOX), Spring JDBC or OJB and use Maven as an alternative to Ant. For a web framework comparison check out my presentation on comparing these frameworks. A more detailed comparison can be found in Spring Live, Chapter 11. AppFuse 1.7 contains all 5 web framework options as well... Equinox is a lightweight version of AppFuse. I was inspired to create it while writing Spring Live and looking at the struts-blank and webapp-minimal applications that ship with Struts and Spring, respectively. These "starter" apps were not robust enough for me, and I wanted something like AppFuse, only simpler." & equinox: framework comparison: "From my learnings, I've created a presentation that you can download." & Download documents & files
