A group of vendors, spearheaded by Sun Microsystems, introduced last week a draft of Java Business Integration (JBI), a blueprint for facilitating the integration of Java SOA (Service Oriented Architecture) software.  The SOA standard was developed by 22 vendors and is endorsed by players such as Novell, Oracle, Apache, and JBoss.  However, one of the drawbacks of the spec is its lack of support of BEA (Nasdaq:BEAS) and IBM (NYSE:IBM), two of the biggest Java vendors.  One potential scenario that could arise as a result is that these two giants might decide to work on their own SOA implementation, which can lead to an additional fragmentation of the Java platform.
