A propertyChange() method should be implemented if a property needs to listen

for changes on some other property. Check the TwineBall sample for

ServiceTypeSingleProperty.

To enable the function of both vetoableChange and propertyChange, the instance of

the property should be added to the propertyChangeListener list. In the

TwineBallMetadataSelection class in the TwineBall sample, the property

representing operations listens on the property for serviceType:

propertyGroup = new WBIPropertyGroupImpl(Constants.SELECTION_PROPERTIES);

propertyGroup.setDisplayName(WBIMetadataDiscoveryImpl.getPropertyName

(Constants.SELECTIONPROPERTIES));

propertyGroup.setDescription(WBIMetadataDiscoveryImpl.getPropertyDescription

(Constants.SELECTIONPROPERTIES));

WBISingleValuedPropertyImpl typeProp = createServiceTypeProperty(propertyGroup);

ServiceTypeSingleProperty operationProp = createNamespaceProperty(propertyGroup);

createMaxRecordProperty(propertyGroup);

createRelativePathProperty(propertyGroup);

// Copy the applied properties to the new instance

if (this.getAppliedSelectionProperties() != null)

EMDUtil.copyValues(this.getAppliedSelectionProperties(), propertyGroup);

typeProp.addPropertyChangeListener(operationProp);

Progress monitor sample:

For enterprise metadata discovery processes that are time-consuming–such as

retrieving information from an EIS and building MetadataObject instances–you can

use the progress monitor.

While you are running the discovery service, the progress monitor can capture

information on current processes and allow you to cancel operations. You can

locate a handle to ProgressMonitor using the

following:WBIMetadataDiscovery.getLogUtils().getProgressMonitor().Asa

process elapses, you can use the setProgress() method to set progress levels that

approach a specified maximum as shown below:

WBIMetadataConnectionImpl.getToolContext().getProgressMonitor().setMaximum(100);

WBIMetadataConnectionImpl.getToolContext().getProgressMonitor().setMinimum(0);

WBIMetadataConnectionImpl.getToolContext().getProgressMonitor().setProgress(50);

WBIMetadataConnectionImpl.getToolContext().getProgressMonitor().setNote

("Getting namespace from Peoplesoft");

WBIMetadataDiscoveryImpl sample:

WBIMetadataDiscoveryImpl is the main entry class for invoking enterprise metadata

discovery.

Interaction between the enterprise metadata discovery service and an EIS

originates in an implementation of the WBIMetadataDiscoveryImpl class. You must

implement the methods described below.

Constructor

The constructor should call super(Bundle Name). The bundle name is the name of

the resource bundle for property-group properties of the enterprise metadata

discovery; for example: super("com.abc.j2c.testapp.emd"). When creating

resource bundles the EMD.properties and LogMessages.properties should share

the same package name.
