WebSphere Integration Developer: Visual Snippet Java Code Generation Is Non-Deterministic

I present the following exhibit: The only difference between these two snippets is the string that I am setting in the commonName attribute. But, let’s look at the java that was generated under the covers for the bottom snippet: boolean __result__31 = (iFlag != null) && (iFlag.trim().equals(“Y”)); if (__result__31){ commonj.sdo.DataObject svcCharVal = __result__34; java.lang.String __result__36 […]

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. […]

WSDL Anti-Pattern: xsd:Any and xsd:AnyType To Encapsulate Future Changes

The cousin to yesterday’s WSDL Anti-Pattern: The ‘Single XML String’ Service is the use of the XSD specification’s ‘any’. ‘Any’ literally means “any well-formed XML contained in this section is valid”. ‘anyType’ means “any valid XSD Type”. We can start to see the correlation between the Single XML String service and the use of these […]

WSDL Anti-Pattern: The ‘Single XML String’ Service

WSDL is a very useful technology. It allows service providers and consumers to agree on namespaces, operation names, the data to be transmitted in a request and the data to expect in a response. All very good things to know, all in a platform neutral way. Now, WSDL tells us what all the elements and […]

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 […]

Impact 2008: Web 2.0 Social Networking Missing In Action

Over a twitter yesterday, James Governor lamented about the lack of official web 2.0 happenings a conference where we’re all talking about mash-ups, integrating communities and mass enablement. IBM’s youTube Channel has a single 1 minute video from day one, theres a twitter account created of the name “Impact2008“* which has no activity. Heck, even […]

Impact 2008: Happy Birthday WebSphere

The marketing says that it’s WebSphere’s 10th birthday on Tuesday. To celebrate, IBM is asking for revised lyrics to the well-known Birthday song. Never being one to pass up on a free chance at bizarre creativity, I’ve shilled-out and submitted: WebSphere *IS* big blue What Can it not Do? We praise you, Dear WebSphere Ten […]

Venting some WebSphere Integration Developer Steam

In the blog Albees Online, Albin Joseph expresses his frustration that he’s stuck using the buggiest IDE in the World (WebSphere Integration Developer). I’m going to include my thoughts below: Most of the times the server wouldn’t change the status to started even if the server is actually started Agreed. There’s something wrong with the […]

Does Commerical Enterprise Software Suck?

In Johannes Brodwall’s Blog, he asks “Why does so much enterprise commercial software suck?”. In it, he mentions that his project migrated off of WebSphere and onto Jetty and regrets that his project didn’t migrate soon. The money quote: But WebSphere is just the most blatant example of software that gives you nothing, gets in […]

WebSphere DataPower vs WebSphere Enterprise Service Bus

Yesterday, I blathered on about how great DataPower would be for usage in WebSphere Process Server. Your developer would be able to stay completely inside the Generic Business Object (GBO) data view while leveraging DataPower’s awesome ability to transform efficiently. Very neat indeed. An interesting is scenario where DataPower IS the ESB. No WebSphere Process […]

Event Sequencing Message Locking – Resolution!

In a previous post, I discussed the DeveloperWorks Process Server Endurance article. In that article, they ran into a situation where the number of maxMessages was breached (100 by default). At my client site, we had a situation where messages in an Event Sequenced queue would remain locked forever, causing the maxMessages to be breached. […]

The best thing to do is try to look at the very top for a non-generic exception that relates to your problem. This article will attempt to describe exactly what happened via the information […]

It’s nice to see IBM come out with a detailed article of whats changed between versions aside from the usual useless marketing banter. WebSphere ESB improvements New mediation primitives let […]

This article provides insight into the various problems and solutions encountered by the WebSphere Process Server Validation team as they performed an endurance run on WebSphere Process Server V6.0.2. Upon […]

BOFactory: create(..) or createByElement(..) ?

The com.ibm.websphere.bo.BOFactory interface defines two methods: DataObject create(namespace, name) DataObject createByElement(namespace, name) Both methods take the same two parameters and both return DataObjects. Most of the time, create() is used and returns the DataObject as expected. Sometimes, though, you’ll find that it returns null when the namespace,name pair is correct. The reason for this peculiarity […]

Goals

I’m a large supporter of the IBM DeveloperWorks Forums for WebSphere Integration Developer and WebSphere Process Server (including WebSphere Enterprise Service Bus). Having the wealth of experience on this platform that I have, I tend to respond to 75%-80% of the questions. Sometimes, a question appears that sparks my brain with a rant or deserves […]
