Seamless source “migration” from SOA Suite 12.1.3 to 12.2.1 using WLST and XSLT by Maarten Smeets

When you migrate sources from SOA Suite 12.1.3 to SOA Suite 12.2.1, the only change I’ve seen JDeveloper do to the (SCA and Service Bus) code is updating versions in the pom.xml files from 12.1.3 to 12.2.1 (and some changes to jws and jpr files). Service Bus 12.2.1 has some build difficulties when using Maven. See Oracle Support: “OSB 12.2.1 Maven plugin error, ‘Could not find artifact com.oracle.servicebus:sbar-project-common:pom’ (Doc ID 2100799.1)”. Oracle suggests updating the pom.xml of the project, changing the packaging type from sbar to jar and removing the reference to the parent project. This however will not help you because the created jar file does not have the structure required of Service Bus resources to be imported. To deploy Service Bus with Maven I’ve used the 12.1.3 plugin to create the sbar and a custom WLST file to do the actual deployment of this sbar to a 12.2.1 environment. A similar solution is described here.
Updates to the pom files can easily be automated as part of a build pipeline. This allows you to develop 12.1.3 code and automate the migration to 12.2.1. This can be useful if you want to avoid keeping separate 12.1.3 and 12.2.1 versions of your sources during a gradual migration. You can do bug fixes on the 12.1.3 sources and compile/deploy to production (usually production is the last environment to be upgraded) and use the same pipeline to compile and deploy the same sources (using altered pom files) to a 12.2.1 environment.
