Justin R. Pennington is a software engineer focused on enterprise e-commerce — primarily IBM WebSphere Commerce and HCL Commerce — with hands-on experience across Java/J2EE, Solr, web services, and the operational side of running large commerce platforms. This blog collects practical solutions to the problems that don’t show up in the official docs: cryptic exceptions, build quirks, configuration gotchas, and the occasional deep dive into blockchain technology.
Everything here is written from real debugging sessions. If it saved me an afternoon, it might save you one too.
