You are very welcome to help us develop Tuscany SDO Java. You may have ideas that you want to pursue yourself or you may wish to pitch in with the design, coding and documentation. If it's the first of these two then please put forward your suggestions on the development mailing list. If it's the latter, then feel free to ask on the mailing list or browse the issue management system. SDO Java Issues are managed in JIRA system. The components for the Tuscany SDO implementation are "Java SDO Implementation", "Java SDO Tools" and "Java SDO Samples" |
