Both during development and maintenance of code, deployment strategies relying on copying of artifacts will fail, or at least complicate the task at hand and frustrate reuse. SOA Suite offers a centralized storage for artifacts (like WSDL, XSD, and XSL files) that can be accessed both at design time and at run-time. It is called the MDS Repository, and comes with Metadata Services on top of it. It is part of the SOA Suite and doesn’t require additional installation. This blogpost will show you how to upload an artifact to the central MDS Repository, and how to use the uploaded artifact in your source code.
Locate and copy the WSDL
Locate the WSDL file in your project on the local file system, for example:
C:\JDeveloper\mywork\AIApocBOUW\CreateInventoryTransactionRIBRMSProvABCSImpl.wsdl. In which a convention like
C:\JDeveloper\mywork\__Workspace__\__project__ is used. You can also determine this path in JDeveloper by selecting the WSDL file and use
CRTL-SHIFT-C (or by selecting contextmenu – Copy Path).
Use an FTP tool to move the file to the server running the SOA Suite. The path to use on the server depends on the application, version and component type. Typically in AIA there is a structure like
$AIA_HOME/AIAMetaData/AIAComponents/ApplicationConnectorServiceLibrary/__Application__/__version__/__componentType__ . Where in AIA component types are ABCS Provider, ABCS Requestor, EBS, et cetera. In other environments you can create your own structure. Since you no longer need a local copy of the WSDL, remove it from your local file system.
Load the WSDL in the MDS Repository
To load the WSDL and other artifacts to the MDS repository there is an ANT script available on the server. To use ANT, make sure the needed environment settings are made correctly. When you installed AIA there is a Shell script available the will source both AIA and ANT environments:
aiaenv.sh. This script can be found in
...../weblogic/aia30/aia_instances/aia30poc/bin. It can be convenient to copy this to your home directory.
- Source AIA and ANT environment:
- Alter the
UpdateMetaDataDP.xml configuration file. It can be found in
In case your vi isn’t up to par use a tool like WinSCP and choose
Edit in the context menu:
UpdateMetaDataDP.xml file alter the file set. In the example on which the screenshot is based
And now you are ready to run ANT using the actual loading script:
ant –f /fs01/app/oracle/esbtst01/weblogic/aia30/Infrastructure/Install/scripts/UpdateMetaData.xml
Check the output of the ANT script:
- check that the correct number of files has been copied.
- the server gave a HTTP response 200.
- The deployment of the composite was successful.
Another check to verify a correct load into the MDS Repository is to use the MDS Browser in JDeveloper to find the file you just uploaded. A refresh of the view could be needed to include the latest changes and additions.
Using the WSDL in the MDS Repository in your source code
The last step is to reference to the WSDL in the MDS Repository, since the file has been removed from the local file system. Double click the
Exposed Service to open the wizard:
Existing WSDL to select the WSDL from the MDS Repository:
Check the change using the source view. In the import of the WSDL in the
composite.xml there should now be an URL referring to
oramds:, like in the example below:
