XML Daily Newslink: Eclipse Swordfish SOA runtime mixes SCA, JBI and OSGi
News: Submitted by carolgeyer on 18. January 2008 - 16:55.
The swordfish (xiphias gladius) uses its sharp elongated bill to slash through its prey making sushi of smaller fish. Likewise, the advocates of a service-oriented architecture (SOA) platform codenamed Swordfish, which is now making its way through the Eclipse incubator process, argue it will slash through obstacles to SOA development.
Difference between join and transition conditions
Forum topic: Submitted by tim.hallwyl on 11. January 2008 - 13:58.
Section 8.2.5 only applies for join conditions. As I understand it, are transition conditions ordinary boolean expressions, with access to all variables and functions. If so, should the transitionCondition element declaration not have been of type tBoolean-expr in the schema? It is of type tCondition, the type used for joinCondition.
Thanks.
Schema types for expressions
Forum topic: Submitted by tim.hallwyl on 11. January 2008 - 13:37.
Section 8.3 list five kinds of expressions: boolean, deadline, duration, unsigned integer and general expressions.
In the XML Schema there is a general tExpression type with five sub-types: tBoolean-expr, tDeadline-expr, tDuration-expr, tCondition and tBranches.
Having tCondition as a special type of boolean expression for join and transition conditions seems reasonable, since the are evaluated diffenrently that ordinary boolean expressions.
