Sun Makes Open-Source Move, Patches Up IBM Relationship: Page 3 of 3

Nevertheless, the Sun-IBM agreement resolves background-licensing issues between the two and ensures a united Java over the next 10 years. At the height of the Sun/IBM conflict five years ago, some observers feared a split between the two and an IBM version of Java emerging to compete with Sun's. At that time, IBM turned away from Sun and endorsed a Microsoft-proposed standard for Web services called Simple Object Access Protocol.

In their joint statement, Sun and IBM said they "reaffirm the value and necessity of Java compatibility across platforms and demonstrate that both companies are committed to Java innovation," the latter a reference to the Java Community Process.

IBM is still absent from Sun's initiative to establish a standard for an enterprise server bus, the Java Business Initiative. On Monday, Sun unveiled a reference implementation of the JBI proposal it launched last fall. JBI 1.0 specifies a set of adapters that work with an enterprise service bus to integrate applications across the enterprise.

BEA Systems, IBM, Iona Technologies, the Sonic Software unit of Progress Software, and Tibco Software all sell commercial versions of enterprise service buses. Sun's JBI 1.0 specification is neutral among the available enterprise service buses, but John Fowler, Sun's executive VP, network systems, explained it creates standard adapters that can be used to connect a messaging system to different applications.
