Passing Parameters to XSLT via BPEL

Remember how difficult it used to be to pass parameters from BPEL to XSLT transform functions in 10g. Well, with the new transformDOC function, this has become very easy. The new transform function now allows multiple source documents. The first one is the main document while the others are taken as parameters. The only problem … Continue reading

Dynamic Value Mapping in OSB via Custom XPaths

I. Overview OSB 11g R1 does not have DVM support. Now this is perfectly fine for clients who are using DVMs as part of the SOA Composites. But considering the fact that Oracle Mediator 11g has DVM functionality, and that many clients would have a migration path from Mediator based artifacts to OSB 11g, this … Continue reading

Importing SOA 11g standard XPath Functions into OSB 11g

Ok, so heres the problem. OSB 11g and SOA 11g XPath functions are not in Sync.¬† So, XSLTs that were developed in SOA 10g cannot be used directly in OSB 11g. One of the strong cases for this is the migration of all ESB based artifacts to OSB artifacts. One of the easiest¬† ways of … Continue reading

XQuery and XSLT Maps

XSLT used to be everywhere prior to OSB. Now, everyone wants to us XQuery over XSLT for various reasons ranging from the highly controversial better performance and better Code Maintainability. Personally, I feel that XQuery is more procedure driven i.e. you-tell-what-you-want-to-do and hence easier and quicker to script than XSLT which is intuitive and more … Continue reading

Reuse BPEL XSLT maps in OSB

Reusing XSLT maps from existing BPEL processes in OSB is quite easy. There is however, a small change required in the namespace of the maps. At a minimal a BPEL process generally involves transformation from a Source namespace to a Target namespace for the invoking and response variables between the Client BPEL process and the … Continue reading
