Welcome! This is a group for anyone interested in Java development. Meetings are held every second Thursday of the month and include opportunities for networking as well as presentations on some topic of interest to Java developers. We meet for dinner/drinks afterward.

Ray Tayek is the leader of the group and organizes our meetings. Philip Yurchuk helps herd the cats.

We have online discussions in two places:

The OCJUG mailing list:

The OCJUG LinkedIn Group:

Hiring managers may post jobs to either place.
