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.
Managing tasks and business processes using WebSphere Business Space
Learn how to create WebSphere BPM V6.1.2 Business Space dashboards using
the run-time artifacts from the WebSphere BPM V6.1.1 Clips and Tacks tutorial.
You’ll create a business space to manage the tasks and business forms input,
run some processes that use forms, and finally create a business space you can
use to monitor the process and tasks.
WebSphere Process Server Disaster Recovery: UUIDs are unique to an install
If you are looking at WebSphere Process Server Disaster Recovery, you should know that the UUID’s that uniquely identify a server in both the Messaging Engine Database and the transaction log are unique for that particular installation. Running the equivalent installation commands on the restored system will not generate a server with the same id. […]

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)

IBM Installation Manager Tip: Don’t “Save Files For Rollback”
The ability to roll back a update is a nifty idea. The theory is that you installed something that broke your platform. You can now just ‘undo’ the install. In practice, it’s a feature that next to nobody uses. It requires a deep-faith in the programmers of the rollback logic to return the system to […]
WebSphere Integration Developer Upgrade from 6.1 to 6.1.2 – Two Hours
I started my update from 6.1 to 6.1.2 and the process took two hours (not including download times). That’s unacceptable. Most of the time was spent installing the WebSphere Process Server fixes. The UI appeared frozen for about an hour (still responsive, just that the progress bar didn’t move). When I jumped down to the […]
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. Interestingly enough, if you deploy the same Mediation Module to WebSphere […]

WebSphere Adapter for JDBC Export and SQL Server 2000: Table Locking while Polling
A technote was published for customers who use the WebSphere Adapter for JDBC for inbound processing of an SQL Server 2000 database. Apparently, the adapter will lock the entire event table (bad!). The ‘fix’ aka workaround is to use a view to the event table and then set a custom property inside the adapter.
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. In this situations, you may see messages on SIB Queues that are in the LOCKED state but are unprocessed. If you factor in a sequential delivering of messages, […]
Tip: WebSphere Process Server – Do not delete the ‘tranlog’ on a production server
In development mode, one of the steps to ‘clean up’ from a wonky process server instance is to delete the wstemp, temp directories along with the ‘tranlog’. The ‘tranlog’ is an internal file that WebSphere Application Server uses to manage in-flight transactions and attempt to recover them should the server crash. When you delete the […]

WebSphere Integration Developer: Struggling with the Business Object Mapper
I had a custom snippet in my map between two string attributes and a list of business objects. The idea being that each string from the source should becomes an entry in the business object list with a wrapper. No problem. I wrote up the snippet to create the destination business object (since it does […]
Use ARM to monitor SCA invocations in IBM WebSphere Process Server
This two-part series shows you how to monitor Service Component Architecture
(SCA) invocations using the Application Response Measurement (ARM) standard in IBM
WebSphere Process Server V6.1. You can use an ARM implementation, such as IBM Tivoli
Composite Application Manager for Response Time Tracking, to generate a graphic view
of SCA invocations. This article, Part 1 of the series, starts by describing ARM and
showing you how to debug synchronous scenarios using Tivoli Composite Application
Manager for Response Time Tracking. In Part 2, you’ll get an introduction to SCA
invocation patterns and learn how to debug asynchronous scenarios.
WebSphere Adapter for JDBC: SetObjectKeys NullPointer Exception

Business Object Maps and ‘Required’ Attributes
Just ran into an interesting scenario. We have a business object with a required attribute (amongst a sea of non-required ones). In a business object map, we only set the non-required ones and never set the required ones to any value. In the above example, ‘productStatus’ is required, ‘name’ is not. This is the Mediation […]

Web services with SOAP/JMS in IBM WebSphere Process Server
This two-part article series shows you how to use SOAP over Java Message Service
(JMS) in IBM WebSphere Process Server and IBM WebSphere Enterprise Service Bus. Learn
how to set up and use SOAP over JMS as configured by default by the IBM
WebSphere Integration Developer tool and how to enable the use of the IBM WebSphere
MQ JMS provider via configuration. In this article, Part 1 of the series, you create and
invoke a Web service using SOAP over JMS and an end-to-end application example, covering
the full process of creating, building, deploying, and testing the applications.
Scenarios covering both point-to-point and publish/subscribe messaging walk you
through the process. In the second article in this series, you’ll
reconfigure a Web service that uses the SOAP over JMS protocol to enable the use of
WebSphere MQ as the JMS provider and allow the transport of SOAP messages via
WebSphere MQ queues.
Problem Determination and WebSphere Integration Developer
In the past, I’ve gone and de-constructed WebSphere Process Server stack traces in an example of problem determination. Now, I’ll talk about what I do when WebSphere Integration Developer goes crazy. A typical WebSphere Integration Developer exception consists of either a builder error pop up dialog or an issue when trying to open an editor. […]

Avoid the WebSphere Integration Developer Debugger
Yesterday, I had a non-descriptive NullPointerException occur within a visual snippet sub-map in WebSphere Integration Developer. The only message written to the log was something that identified which transformation in the sub-map failed. There was nothing about what line was bad. Rather than filling my code full of “Got Here” and “Did this Runs”, I […]
Close WebSphere Integration Developer when updating Fixpacks for WebSphere Process Server
I was attempting to install WebSphere Process Server v6.0.2.3 on the server installed with WebSphere Integration Developer.
