It’s satisfying adding a bunch of IBM acronyms to my “marketable skills.” They’re not that intimidating after all!
I spent the morning and part of the afternoon pair-programming with Bharat Boddu on a time-sensitive project involving an IBM software stack. It was a struggle in the beginning. Both of us were new to all of this, and the sheer volume of information available for Rational Software Architect, Websphere Application Server, DB2, and other parts of the stack was overwhelming. The simplest of things tripped us up because we didn’t know how to debug them. For example, we learned the hard way that adding the DB2 classes to the project’s classpath didn’t mean that they were part of the runtime configuration classpath when the web services were deployed to the server. I also spent what seemed like an hour trying to deal with this issue from the web service explorer:
IWAB0135E An unexpected error has occurred. 302 Found
(Solution: Check the endpoints you’ve defined in your WSDL, or define new ones. example.org won’t work.)
Once we got over those roadblocks, things flowed smoothly. We used Rational Software Architect to define web services, deployed them on Websphere Application Server, and queried a DB2 database. We also figured out how to work with complex data types and lists for both input and output. We needed to figure out how to consume web services too, so I dug around until I found a web service defined by a WSDL that played well with our configuration. All these bits and pieces will come in handy when we start working on the real requirements.
I can feel myself learning all sorts of new things. I love these moments: the magic of concepts snapping together, like the way you reach out and find things right where you’re looking for them. And I’m slowly inching my way into another area of developer awesomeness: dealing with middleware, service-oriented architecture, and all sorts of other business-y things.
Here’s what I do well, and what I’m learning to do even better.
I’m glad my manager took a chance on these projects, even though I did have to work through looming panic. ;) (It gets much easier to deal with intimidating systems when you get going!)
This is good. I like this feeling. And I can still fit in sleep, presentations, blog posts, homework help, and sanity breaks. =) Hmm…
