Using Lotus Expeditor property broker to communicate with local portlet
Perform the following steps to use the property broker between RCP and Portlet:
1 Develop a portlet which sends message out. Define the portlet message using wsdl. See the following example code:
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="GeneratedPropertyBrokerDefinition"
targetNamespace="http://com.ibm.propertybroker.standardtypes"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:portlet="http://www.ibm.com/wps/c2a"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:tns="http://com.ibm.propertybroker.standardtypes"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<types>
<xsd:schema
targetNamespace="http://com.ibm.propertybroker.standardtypes">
<xsd:simpleType name="WireStringType">
<xsd:restriction base="xsd:string" />
</xsd:simpleType>
</xsd:schema>
</types>
<message name="wire_message">
<part name="outputPart1" type="tns:WireStringType" />
</message>
<portType name="com.ibm.propertybroker.standardtypes_Service">
<operation name="PortletMessageGeneratorAction">
<output message="tns:wire_message" />
</operation>
</portType>
<binding name="com.ibm.propertybroker.standardtypesbinding"
type="tns:com.ibm.propertybroker.standardtypes_Service">
<portlet:binding />
<operation name="PortletMessageGeneratorAction">
<portlet:action activeOnStartup="true"
caption="message generator action"
description="message generator action"
name="PortletMessageGeneratorAction" selectOnMultipleMatch="false"
type="standard" actionNameParameter="ACTION_NAME" />
<output>
<portlet:param boundTo="request-attribute"
caption="message_caption" name="portlet_message" partname="outputPart1" />
</output>
</operation>
</binding>
</definitions>
Use both name and namespace to specify a property. Name=”portlet_message”, namespace=”http://com.ibm.propertybroker.standardtypes”.
2 Turn this portlet project into the plug-in project.
3 For the services that need to receive messages from this portlet, you need to add property listener to the property broker service. See the following example code:
final IProperty property = ServiceManager.createProperty("portlet_message",
"http://com.ibm.propertybroker.standardtypes");
ServiceManager.getPropertyBroker().addPropertyListener(new IPropertyListener() {
public void handlePropertyChange(IPropertyValue value) {
if (property.equals(value.getProperty()))
aBTTText.setText(value.getValue().toString());
}
}, property);
