ADF: JMX Data Control

Applicable to ADF 11.1.1.7.0 and Weblogic 10.3.6

Recently I had an requirement to display list of OID groups associated with user in OID(LDAP) in an ADF application. And I used JMX(Java Management Extensions) data control to perform query operations on OID configured in Weblogic server. Here is the steps I followed to develop it.

1. Create an ADF application and create JMX connection to weblogic server as shown below.
    URL Provider Path: /jndi/weblogic.management.mbeanservers.domainruntime

2. Create JMX Data Control as shown below.
   

Note: Select OID Provider under AdminServer. Don't select OID provider displaying directly under Security option.

3. Data Control will be displayed as shown below

    DataControl.dcx content:

    <?xml version="1.0" encoding="UTF-8" ?>

    <DataControlConfigs xmlns="http://xmlns.oracle.com/adfm/configuration"

                        version="11.1.1.64.93" id="DataControls"

                        Package="com.lkakarla.view">

    <AdapterDataControl id="UserAdminDC"

                        FactoryClass="oracle.adf.model.adapter.DataControlFactoryImpl"

                        ImplDef="oracle.adfinternal.model.adapter.jmx.JmxDataControlDef"

                        SupportsTransactions="true" SupportsSortCollection="false"

                        SupportsResetState="false" SupportsRangesize="true"

                        SupportsFindMode="true" SupportsUpdates="true"

                        Definition="JmxDataControl" BeanClass="JmxDataControl"

                        xmlns="http://xmlns.oracle.com/adfm/datacontrol">

      <Source>

        <JMXDCProperties xmlns="http://xmlns.oracle.com/adfm/adapter/jmx">

          <MBeanServerConnection connectionName="UserAdmin"/>

           <JMXBean displayName="myrealmOID"

                    objectName="Security:Name=myrealmOID,Location=AdminServer">

            <UpdatableOperations>

              <Operation name="listGroupMembers"/>

              <Operation name="listMemberGroups"/>

            </UpdatableOperations>

          </JMXBean>

        </JMXDCProperties>

      </Source>

     </AdapterDataControl>

   </DataControlConfigs>

4. Create a Page/Fragment and drag & drop method 'listMemberGroups' from Data Control to Page/Fragment. And Add following other methods as method bindings to Page definition. After adding the page definition will be dsipalyed as shown below.

   haveCurrent
   getCurrentName
   advance

5. Sample Page Code:

        <af:resource type="javascript">
          function onCb1EnterKey(event) {
              if (event.getKeyCode() == AdfKeyStroke.ENTER_KEY) {
                  var itField = event.getSource();
                  var btn1 = itField.findComponent('cb1');
                  var partialSubmit = true;
                  AdfActionEvent.queue(btn1, partialSubmit);
                  event.cancel();
              }
          }

        </af:resource>

      <af:showDetailItem text="Search User Roles" id="sdi546"
                       stretchChildren="first" styleClass="AFStretchWidth"
      <af:panelGroupLayout id="pgl2" styleClass="AFStretchWidth">
        <af:spacer width="10" height="10" id="s305"/>
        <af:panelBox text="Search User" id="pb1" styleClass="AFStretchWidth">
          <af:panelFormLayout id="pflu1" styleClass="AFStretchWidth">
            <af:panelLabelAndMessage label="Username" id="plam3" for="iuser1">
              <af:panelGroupLayout id="td1" layout="horizontal">
                <af:inputText id="iuser1"
                              binding="#{pageFlowScope.userBean.userName}"
                              placeholder="Enter User Email ID to Search"
                              autoSubmit="true">
                  <af:clientListener method="onCb1EnterKey" type="keyUp"/>
                </af:inputText>
                <af:spacer width="10" height="10" id="s10"/>
                <af:commandButton id="cb1"
                                  actionListener="#{pageFlowScope.userBean.searchGroups}"
                                  blocking="true" icon="/images/ico_search.png"
                                  text=" " partialSubmit="true"
                                  shortDesc="Click to Search Groups"/>
              </af:panelGroupLayout>
            </af:panelLabelAndMessage>
          </af:panelFormLayout>
        </af:panelBox>
        <af:spacer width="10" height="10" id="s1"/>
        <af:panelBox text="User Groups" id="pb14" styleClass="AFStretchWidth">
          <af:table value="#{pageFlowScope.userBean.userGrpList}" var="row"
                    rowBandingInterval="1" id="t2" partialTriggers="::cb1"
                    columnStretching="column:c1">
            <af:column sortable="false" headerText="Group Name" id="c1"
                       width="200">
              <af:outputText value="#{row.groupName}" id="ot7"/>
            </af:column>
          </af:table>
        </af:panelBox>
      </af:panelGroupLayout>
