Altova XMLSpy, testing custom functions in xsl transformations

In our middleware solutions (Oracle SOA Suite) we use a lot of xsl transformations. Part of these transformations use database backend systems to do lookups for transforming internal values to external values (which can then be communicated to the customers). In the Oracle SOA Suite you can create custom xsl function and store the jar in the domain/lib folder and then you will be able to use it in the xsl transformations. We use Altova XMLSpy a lot for creating all these xsl...

Oracle BPEL, retrieving the validate activity fault message

The 'Validate' activity in Oracle BPEL gives us the functionality to validate variables again schema definitions.

When you're using some generic error hospital functionality you also want this message to be available in there. First try would be, add a Scope around the activity and catch the 'invalidVariables' System Fault. When using a getFaultString on the fault variable or after...

Oracle JCA Database adapter and performance win on big clobs

In a few of our services in bpel and osb we're inserting a lot of data (big payload messages) into the database by use of the jca db adapter. We noticed performance would drop hugely when the db adapter needed to insert big payloads (CLOBS) and when the stream of messages on these services would continue even more performance would dramastically go down on the system. After disabling "wrap data types" on the datasource in Weblogic we had a pretty good performance win on processing big clob...
