console.

| void | upgrade(String workspaceRoot, List<String> serviceUnitRoots)
This method is called by the JBI runtime to allow a component to upgrade
its workspace and any existing Service Units to match the new version of
the component. |
| upgrade | | void upgrade(String workspaceRoot, List<String> serviceUnitRoots) throws JBIException(Code) | | This method is called by the JBI runtime to allow a component to upgrade
its workspace and any existing Service Units to match the new version of
the component. The JBI runtime copies the existing workspace root to the
new workspace root prior to calling this method, so that the component
can examine the contents of the workspace root to determine the version
of the component from which the upgrade is being made. All updates to the
workspace root and Service Unit roots are done in-place; in the event of
a failure, the JBI runtime reverts back to the original workspace root
and the Service Unit roots.
Note that the component must ensure that it never holds open references
to any files in the workspace root or any of the Service Unit roots upon
returning from this method. Failure to do so will cause problems when
the runtime attempts to complete the upgrade processing.
Parameters:
workspaceRoot - the workspace root for the new version of thecomponent that will replace the currently installed version. This ispopulated with the contents of the original workspace root and thecomponent must update it to match the new version of the component.
Parameters:
serviceUnitRoots - a list of directory paths to all of the ServiceUnits currently deployed to the component. The component must update allof these to match the new version of the component.
exception:
JBIException - when there is an error requiring that the upgradebe terminated. |
