How to load external resource bundle using java in ADF

Resource bundles are used to achieve Internalization in the Web based applications. They contain Key / Value pairs. Key identifies local-specific object in resource bundle.

Generally, when we create a “ViewController” project in ADF, It creates a default property file inside the project of “Resource Bundle Type” as Properties Bundle.

When an application is deployed, location of resource bundle will be inside EAR file as a result any update made in the component label requires application re-deployment. The issue can be resolved easily just placing resource bundle property file outside the EAR.

Below example will explain the scenario and configurations required:

Configure ListResourceBundle in project:

Goto-> project properties -> Resource Bundle

Register resource bundle in your application

Open faces-config.xml file and define resource bundle.


Code snippet of java Class:

package view;


import java.util.Enumeration;
import java.util.ListResourceBundle;
import java.util.Properties;

public class MyResourceBundle extends ListResourceBundle {

    static final Object[][] contents = readPropertyFile();

    public Object[][] getContents() {
        return contents;

    public static Object[][] readPropertyFile() {
        Object[][] data = null;
        try {
//Property file path in system
                       String nodeProFile =
                "C:\\Users\\Gopal\\Desktop\\resource bundle\\";
            System.out.println("nodeProFile : " + nodeProFile);
            Properties prop = new Properties();
            //load a properties file
            prop.load(new FileInputStream(nodeProFile));
            Enumeration propKeys = prop.keys();
            System.out.println("Property size : " + prop.size());
            data = new Object[prop.size()][2];
            int i = 0;
            while (propKeys.hasMoreElements()) {
                String key = (String)propKeys.nextElement();
                String value = prop.getProperty(key);
                System.out.println("Key  " + key + " -> : " + value);
                data[i][0] = key;
                data[i][1] = value;
        } catch (FileNotFoundException fnfe) {
        } catch (IOException ioe) {
        return data;

How to Export adf table record in xls file using exportCollectionActionListener tag

Data of the collection components in ADF such as table, tree or treeTable can easily be exported in the form of xls file using ADF exportCollectionActionListener tag. It allows action events to export data from the colleection component.

<af:exportCollectionActionListener/> id attribute will refer to the collection component Id.

Find the sample code snippet for exporting department table records.

<af:panelCollection id="pc1" styleClass="AFStretchWidth">
            <f:facet name="toolbar">
              <af:toolbar id="t2">
                <af:commandToolbarButton text="Export" id="ctb1">
                  <af:exportCollectionActionListener type="excelHTML"

id="table" ....
            ..................................  ...................
            ............ >

By default the extension of the file downloaded will be xls. We can also export the record in doc format by just giving name of a file such as DepartmentExcel.doc in the attribute filename.
