Need a Java batch step on z/OS to read a FB file and write another. Team mentioned JZOS. Is that still what people use in 2026 or has something replaced it?
JZOS is still common for traditional dataset I/O from Java batch. Some newer work uses ZOAU from Python instead, or record I/O via other IBM libraries, but JZOS samples are what our Java-on-Z folks still copy.
We wrap JZOS in a tiny helper class so app code does not touch the low-level APIs directly. Helps when IBM shuffles packages.
