Onur Kat.

SAP Commerce & DevOps engineer.
Maker of free developer and document tools.

From commerce infrastructure to everyday paperwork,
I build software that makes complex work simpler.

01 / For developers

Less waiting.
More building.

An IntelliJ plugin that ends restart loops for SAP Commerce and Spring, and a toolbox for the small jobs in between.

JetBrains Marketplace

Reclazz

Hot-reload for SAP Commerce (Hybris) and Spring, right in IntelliJ IDEA.

  • Save an items.xml and it regenerates and reloads: no ant clean all, no restart
  • Classes swap in about 50 ms; Spring beans, MVC mappings, ImpEx, properties and backoffice labels follow
  • Methods added after startup are found: endpoints, @Bean factories, listeners and Kafka, JMS or RabbitMQ consumers
