IBM was one of the early backers of Sun's Java software, which theoretically allows a program written in the Java language to run on any Java-enabled computer. However, the company has been unhappy with the degree of control Sun maintains over Java.
IBM has said Sun "betrayed" IBM by going back on a verbal promise to turn control of Java over to an industry group.
IBM still has Java firmly entrenched in its product line, working to speed up the "virtual machine" component of Java and using Java across its four server lines--the Netfinity, RS/6000, AS/400 and S/390.
Sun released Java 2 version 1.3 this week.
IBM will release Java 2 version 1.3 software for its four server lines by the summer, the company said. It will run on the Windows, Linux and OS/2 operating systems for Intel-based Netfinity servers. By the end of the year, Java will run on three operating systems on Intel's upcoming Itanium processor.
