Securing JMS connections to WebSphere Enterprise Service Bus V6.1

Security is an integral part of SOA, and since WebSphere ESB is at the heart of many SOA solutions, the security of a WebSphere ESB server and its transports is vital to the enterprise systems
that use it. Messaging, such as the JMS implementation provided by WebSphere ESB, is particularly important for business applications because of its reliability, performance, and asynchronous nature.
This article shows you how to implement security with an example using WebSphere ESB V6.1 and a J2EE client container application communicating via JMS messaging.

Establish a policy-driven SOA using WebSphere Service Registry and Repository and WebSphere ESB

The WS-Policy specification provides a simple language for expressing
policies supported by Web services. IBM WebSphere Service Registry and Repository
supports loading, changing, and retrieving policy documents, and also supports
using policy attachments to link a given policy with a service. This can then be
used by a run time component, like an Enterprise Service Bus, to retrieve
defined policies for a particular service or operation and act accordingly.
This article shows how you can utilize standard WS-Policy documents stored in a
registry to impact run time behavior in an ESB — and then change that behavior
on the fly with no code changes or redeployment. (IBM WebSphere Developer Technical Journal)

WebSphere Enterprise Service Bus does not support Event Sequencing

Cheers to David Currie for pointing out that while the WebSphere Integration Developer user interface allows you to specify an event sequencing qualifier inside a mediation module, if you attempt to deploy the solution to an WebSphere Enterprise Service Bus Server, you’ll get exceptions.

WAS: Resolution to Messages in the SIB locked forever

In a cluster where the messaging engine has failed over between nodes, a situation could arise where the transaction log (‘tranlog’) has become corrupt or is unrecoverable.
