Document metadata Set/Get

WebCenter Content User Interface – Get and Set Document’s Metadata

Hi all,

In my previous post about WebCenter Content User Interface I have written an overview about the available features of this new UI as well as how to start customizing it, and my experience and important milestones regarding installation. You can find my previous post here.

Today I’m going a little further and focus the attention on how to get and set document’s current properties and metadata attributes using the API available in the “WccAdfCustomization” application.

In my last post I’ve dragged-and-dropped a button to the “docInfoTabs.jsff” page that you can find inside of the “WccAdfLibrary.jar” library of the ViewController project. This is how it looks like:MyCustomButton

Now what we want is to get both document’s properties and metadata, and then set the comments for this same document when we click on the button. To do this we need to perform the following steps:

  1. Open the JDeveloper with “Default Role”. Then go to the ViewController project and create “MyCustomClass” java class. Create an action event listener method to be used by our button.MyCustomClass
  2. Assign “MyCustomClass” java class to the managed beans of “adfc-config.xml” file. From now on this class is available in the context of the “docInfoTabs.jsff” page.ManagedBean
  3. Go to your “docInfoTabs.jsff.xml” file and set the actionListener property like is shown in the next image:ActionListener
  4. Our “docInfoTabs.jsff” page is invoked inside “wccdoc.xml” bounded task flow. If you go to Managed Beans tab you can see the available classes inside it. We will take advantage of “DocInfoBean” class.WccdocTaskFlow
  5. Let’s return to our “MyCustomClass” java class and insert the following code inside “myCustomButtonAction”.
package wcc.custom.view;


import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

import javax.faces.component.UIComponent;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;

import oracle.wcc.adf.model.Attachment;
import oracle.wcc.adf.model.Revision;
import oracle.wcc.adf.model.form.Field;
import oracle.wcc.adf.model.form.Form;
import oracle.wcc.adf.model.form.Item;

public class MyCustomClass {
    public MyCustomClass() {
    public void myCustomButtonAction(javax.faces.event.ActionEvent p1) {
        //Getting document's properties
        //Getting the instance of 'DocInfoBean' class.
        DocInfoBean docInfoBean = (DocInfoBean)ADFUtils.getValueFromViewScope("wccDocInfoBean");
        //Getting the current revision of the selected document.
        Revision revision = docInfoBean.getRevision();
        System.out.println("Document Title:" + revision.getDDocTitle());
        System.out.println("Document Author: " + revision.getDDocAuthor());
        System.out.println("Document Last Modified Date: " + revision.getDReleaseDate());
        System.out.println("Document Status: " + revision.getLocalizedDStatus());
        System.out.println("Document Revision Number:" + revision.getDRevLabel());
        System.out.println("Document Comments: " + revision.getXComments());
        System.out.println("Document Profile: " + revision.getXIdcProfile());
        System.out.println("Document Type: " + revision.getDDocType());
        System.out.println("Document Format: " + revision.getDFormat());
        System.out.println("Document File Size: " + revision.getDFileSize());
        //Getting all metadata of the current revision of the selected document.
        DynamicFormBean dynamicFormBean = docInfoBean.getMetadataFormBean();
        Form form = dynamicFormBean.getForm();
        HashMap<String, Serializable> fieldValues = form.getFieldValues();
        Iterator iter = fieldValues.entrySet().iterator();
        while (iter.hasNext())
            Map.Entry pair = (Map.Entry);
            System.out.println(pair.getKey() + " = " + pair.getValue());
        revision.setXComments("My Custom Comment");
        //Set document's metadata for the current revision.

6. The “getValueFromViewScope” method in my ADFUtils class look likes this:

public static Object getValueFromViewScope(String variable) {
      return AdfFacesContext.getCurrentInstance().getViewScope().get(variable);

7. Finally run your application and test the button.
