Introduction

Due to the tighter integration of Oracle Service Bus 12c in the whole Oracle SOA Suite product it’s now much easier for developers to use general SOA Suite components like the Domain Value Map (DVM).

Getting Started

First I use the OSB 12c clone project ability to copy th earlier created/blogged OSB 12c Database adapter project and create a project named GetCaseServiceDVM. In the new project we add a Domain Value Map (DVM):

01

The file name and description speak for themself. The Initial DVM Entries forces us to define the minimum amount of 2 domain names (source and target of our value) and if we want we can inmediately configure the 1st record here.

02

The result is a DVM file in our project which we can easily edit within JDeveloper 12c.
For this blogpost we will add 2 records which will allow us to translate the value “1” and “2” which we receive from the database to a basic description of that value.

03

In our XSLT transformation we can drag the DVMFunctions:lookupValue on our canvas.
(You can easily find the function using the search function in components)

04

05

Finally we can configure the DVM input fields with the 5 arguments:

  1. The relative path (including the SBProject to your DVM file without mentioning the .DVM extension)
  2. Source table
  3. mapping of the input element we want to translate
  4. Target table to retrieve that specific output value
  5. Default value, in case no match was found in the DVM

06

In the source code of the XSLT this will look like this:

<tns:Type id="{/ns0:OutputParameters/ns0:GET_CASE_BY_CASENUMBER/ns0:CASETYPE}">
<xsl:value-of select='DVMFunctions:lookupValue ("GetCaseServiceDVM/CaseType", "Type", string (/ns0:OutputParameters/ns0:GET_CASE_BY_CASENUMBER/ns0:CASETYPE ), "Description", "Unknown" )'/>
</tns:Type>

If we test the result we see that the source element with value “2” is succesfully translated to the “Claim” value.
