Deploy versioned artifacts to Oracle WebLogic
The Deploy WebLogic server (WLS) plugin allows you to manage deployments and resources on an Oracle WebLogic server. With this plugin, you can deploy multiple versions of the same application at the same time, which is known as a side-by-side deployment or versioning.
Artifact versioning involves several properties on the artifact configuration item (CIs):
versioned: Indicates that the artifact is versioned
versionIdentifier: The artifact version (not needed if automatic versioning is enabled)
automaticVersioning: Indicates that the plugin should automatically version the artifact
manifestVersionProperty: The property in the artifact’s manifest file that the plugin can use to automatically derive its version
versionExpression: A FreeMarker expression that the plugin uses to derive the version
To explicitly set the version, use the
versionIdentifier property. The plugin will use this value when deploying, updating, or undeploying the application.
If you do not want to set the version explicitly, you can use automatic versioning wherein the plugin derives update version numbers automatically. If
automaticVersioning is set to “true” or if
versionIdentifier is blank, the plugin will automatically version the artifact.
There are two methods for deriving the version:
- The plugin uses the version as defined in Deploy. For example, for
Applications/MyApp/1.0, the version would be
The plugin gets the version from the manifest file.
manifestVersionPropertyidentifies the variable in the artifact’s manifest file that defines its version. By default, this is
Extension-Name. If this variable has a value, then the plugin uses the CI’s
versionExpressionproperty to derive the version.
versionExpressionis a FreeMarker expression that the plugin uses to derive the version. By default, it produces a version as follows:
- If the
Implementation-Versionvariable is present, that variable is used
- If both
- If the
Tip: If the artifact’s manifest uses the
Extension-Name variable, the name of the artifact CI should match its value.
You can set CI properties in the manifest of a deployment package (DAR file) before importing it, on the CI in the Repository, or in the properties of a mapped deployed. For more information about CI properties, see the WebLogic Plugin Reference.
manifestVersionProperty CI property defaults to “Extension-Name”. You can change the default in the
wls.WarModule.manifestVersionProperty property in the
versionExpression uses the following FreeMarker expression to calculate the version:
You can change the default in the
wls.WarModule.versionExpression property in the
