A couple of months ago, I reviewed the process for deploying Mule Galaxy, our SOA platform, onto Amazon’s EC2. Not long after that, I was introduced to cloudtools, a set of tools for deploying, managing, and testing Java EE applications on EC2. With these tools, it becomes trivial to deploy an application like Mule Galaxy to the cloud in minutes, rather than hours.

Error Handling in Mule

0

Mule provides different approaches to handling errors. You can set exception strategies for connectors, models, and individual . You can use the exception router to specify where the message goes when an error occurs. And you can use the exception type filter for fine-grained control. Following is an introduction to these approaches.

When wiring your Mule together, new users sometimes get confused about when to use an outbound router and when it’s sufficient to simply get a reply. Following is a description of the three message styles you can use to get a response from your Mule .

Dallas JavaMUG

0

Continuing my whirlwind speaking tour on Mule, I landed in Dallas this week to talk to the JavaMUG. This was my first MUG (I’ve been to JUGs, SIGs, Camps, and Meetups, but never a MUG), and I was blown away to walk into a room of 75+ people all there to hear about Mule (okay, the free pizza and soda probably helped, too). Supposedly it was their largest attended event in several years. I gave a similar talk last month in San Francisco, but in Dallas I expanded a little on my thoughts about SOA and the Cloud.

Galaxy on EC2 in one hour!

0

We have been running Galaxy successfully on our in-house servers and laptops for demo purposes for some time now and decided that having a running image of Galaxy on Amazon’s EC2 was the next logical step. Galaxy in the cloud gives us the opportunity to expose a running instance to a much wider audience than might otherwise interact directly with the product.

Are you currently using Mule or evaluating Mule for use with your WebSphere MQ system? Do you need to utilize WebSphere MQ specific headers, message types, and character code IDs with Mule? Would you like to know how to deploy Mule for maximum reliability when coupled with WebSphere MQ?

Learn from the MuleSource technical team how to integrate Mule with WebSphere MQ using the premium WebSphere MQ transport that is packaged with Mule Enterprise. A common scenario supported by Mule Enterprise will be demonstrated: namely, how to exchange messages with native MQ applications. The solution will demonstrate implementing synchronous request-reply using replyTo headers and correlation IDs.

On Monday, I spoke to a standing room only crowd at the San Francisco Java Users Group about using the Mule ESB to integrate applications. We talked about:

  • What Mule is and what is the difference between integration and SOA
  • Why use a Mule for integration
  • How Mule helps with integration in the Cloud
  • Best practices for planning and implementation
  • Test driven development with Mule

Storing Objects in the Registry

0
Note that this approach is no longer recommended if you are using Mule 3.0.0 or later. Instead you can use the ObjectStore. This allows use to store objects in memory, in a persistent store or across Mule HA clusters automatically. You can learn more about Mule 3.0 here and download it here.

Recently, there was a great question on one of the Mule mailing lists about where to store runtime data that can be used across the app. If you need to store runtime data that is available across your Mule application, you can store the data as objects in the Mule Registry. You can get a handle to the Registry from anywhere that you have access to the MuleContext, as in most Mule entities. For example, you could store the object as follows:

Mule IntelliJ Tips

7

As some may know, we have been working on our open source Mule IDE based on Eclipse. However, with the schema-based configuration in Mule, IntelliJ IDEA users get some great features to help them build mule applications quicker too.
