"In a couple of weeks, we will be announcing a breakthrough in programming techniques," Greg Papadopoulos, chief technology officer at Sun.
Sun plans to announce the new tool during its 6 February conference for analysts in San Francisco.
Papadopoulos said the tool would automatically generate lines of Java code for Web service-type applications, reducing some of the work associated with writing new applications. It will also include features designed to improve the quality of code without altering the applications.
Sun is trying to lure developers toward its Sun Open Net Environment (ONE) architecture for building and deploying Web services and has promoted Java as a key piece of Sun ONE.
