This post is about skinning af:inputFile, see how default inputFile looks on page

See how ADF Skin changes it's appearance :)
Change basic inline style of af:inputFile (background color and design) :

/**Skin Selector to change inline style of af:inputFile**/

af|inputFile {
    background-color: Green;
    border-radius: 20px 20px 20px 20px;
    padding: 5px;
}

Output on page-

Change label style of af:inputFile :

/**Skin Selector to change label style of af:inputFile**/
af|inputFile::label {
  font-weight:bold;
  color:white;
  font-family: cursive;
}

Output on page-

Change content style of af:inputFile (background color, design of content only) :

/**Skin Selector to change content style of af:inputFile**/
af|inputFile::content {
    color: #ff6363;
    font-weight: bold;
    border-color: #79bc79;
    border-style: solid;
    border-width: thin;
    border-radius: 15px 15px 15px 15px;
    padding: 5px;
    background-color: #d6ffd6;
    font-family: cursive;
}

Output on page-

After selecting a file, update button appears -

On click of update button a popup with af:inputFile appears-

Change update button style of af:inputFile:

/**Skin Selector to change style of update button of af:inputFile**/
af|inputFile af|commandButton {

Apply sorting to POJO based af:table programmatically , Using custom sort listener in ADF

Again a post about POJO based table , previously i have posted about-

1.Populating and adding records in POJO based table
Populate af:table programmatically from managead bean using POJO
2. Gettting selected rows from POJO based table
Get selected row (single/multiple) from POJO based table in ADF

This post is about applying sorting to POJO based table , when we drop a viewObject as af:table on page then framework provides sorting and filtering features declaratively, but when populating table from managed bean using List(POJO) then it is not there so we have to do it manually

To understand this post completely , go through previous posts and check attached application there
I have used a PersonBean java bean class to contain columns of table or you can say there is a List of PersonBean type that populates data in af:table. (This is the basic information about application)

Now what to do , see step by step implementation-

• Select table on page editor and create a sortListener in managed bean to handle sortEvent





• Now what we have do in sort listener ?
  1.Get active sort criteria using sortEvent
  2.Remove that sort criteria
  3.Sort List Data Structure that is used to populate af:table
  4.Apply sort criteria again on af:table
  See code written in managed bean-



    //List to store sort criteria
    private List<SortCriterion> sortedTableList = new ArrayList<SortCriterion>();

    public void setSortedTableList(List<SortCriterion> sortedTableList) {
        this.sortedTableList = sortedTableList;
    }

    public List<SortCriterion> getSortedTableList() {
        return sortedTableList;
    }

    /**Custom Sort Listener for POJO based af:table
     * @param sortEvent
     */
    public void tableSortListener(SortEvent sortEvent) {
        //Get active sortCriteria on table
        List<SortCriterion> activeSortCriteria = sortEvent.getSortCriteria();
        SortCriterion sc = activeSortCriteria.get(0);
        // Remove active criteria from table
        this.removeSortCriteria(sc);
        //Sort List that populates table using Comparator interface
        applySortAsPerColumn(sc.getProperty());

        // Add the current criteria to the list
        this.sortedTableList.add(0, sc);
        // Apply sort criteria to table
        RichTable richTable = (RichTable) sortEvent.getComponent();
        richTable.setSortCriteria(sortedTableList);

    }

    /**Removes sort criteria*/
    private boolean removeSortCriteria(SortCriterion sortCriterion) {
        //Checks that if any sortCirteria is present in list , if yes then remove it
        if (sortedTableList != null && sortedTableList.size() > 0) {
            for (SortCriterion sc : sortedTableList) {
                if (sc.getProperty().equals(sc.getProperty())) {
                    sortedTableList.remove(sc);
                    return true;
                }
            }
        }
        return false;
    }


Now logic to apply programmatic sort starts from here , we have to sort List using Java Comparator interface
To Read more - How to sort ArrayList using Comparator?     Comparator interface



    private void applySortAsPerColumn(String criteria) {
        //Get List that populates table
        List<PersonBean> list = getPersonList();
        //Check which column's sorting is triggered from UI
        //and then sort list on basis of that attribute
        //Sorting of collection makes use of Comparator interface, Read about it
        if ("name".equalsIgnoreCase(criteria)) {
            Collections.sort(list, new ProgTableBean.PersName());
        } else if ("mobNo".equalsIgnoreCase(criteria)) {
            Collections.sort(list, new ProgTableBean.MobNo());
        } else if ("salary".equalsIgnoreCase(criteria)) {
            Collections.sort(list, new ProgTableBean.Salary());
        }
    }
    // Comparator for all attributes to sort List according to different attributes

    public static class PersName implements Comparator<PersonBean> {
        private int flag = 1;

        @Override
        public int compare(PersonBean o1, PersonBean o2) {
            return flag * o1.getName().compareTo(o2.getName());
        }
    }


    public static class MobNo implements Comparator<PersonBean> {
        private int flag = 1;

        @Override
        public int compare(PersonBean o1, PersonBean o2) {
            System.out.println("In 2**");
            return flag * o1.getMobNo().compareTo(o2.getMobNo());

        }
    }


    public static class Salary implements Comparator<PersonBean> {
        private int flag = 1;

        @Override
        public int compare(PersonBean o1, PersonBean o2) {
            return flag * o1.getSalary().compareTo(o2.getSalary());
        }
    }




• Now on page ,select table and set sortable true for each column and set sortProperty same as column name
  Check af:table source after setting all properties



<af:table var="row" rowBandingInterval="1" id="t1" value="#{viewScope.ProgTableBean.personList}"
                          partialTriggers="::b1" rowSelection="multiple" binding="#{viewScope.ProgTableBean.tableBind}"
                          selectionListener="#{viewScope.ProgTableBean.tableSelection}"
                          sortListener="#{viewScope.ProgTableBean.tableSortListener}">
                    <af:column sortable="true" headerText="Name" id="c1" width="150" sortProperty="name">
                        <af:outputText value="#{row.name}" id="ot1"/>
                    </af:column>
                    <af:column sortable="true" headerText="Mobile Number" id="c2" sortProperty="mobNo">
                        <af:outputText value="#{row.mobNo}" id="ot2"/>
                    </af:column>
                    <af:column sortable="true" headerText="Salary" id="c3" align="right" sortProperty="salary">
                        <af:outputText value="#{row.salary}" id="ot3"/>
                    </af:column>
                </af:table>

Get selected row (single/multiple) from POJO based table in ADF

Previously i have posted about populating af:table from managed bean using POJO and adding records in it, Check this-
Populate af:table programmatically from managead bean using POJO 
In this post i am extending previous post application
This post is about getting selected row from POJO based table , It is a common requirement while using af:table based on POJO

Get single row using custom selection listener-

SelectionListener  handles selection event of table , whenever user selects a row in table ,selection listener is fired
Set table RowSelection property to single (to select one row at a time) or multiple (to select multiple row ) and create a custom selection listener in managed bean that will handle table's selection event

See selection listener code in managed bean we can get selected row  using this -

import oracle.adf.view.rich.component.rich.data.RichTable;
import org.apache.myfaces.trinidad.event.SelectionEvent;

 /**Method to get selected row(single)
     * @param selectionEvent
     */
    public void tableSelection(SelectionEvent selectionEvent) {
        //Get table from selectionEvent
        RichTable richTable = (RichTable) selectionEvent.getSource();
        //Cast to the List that populates table
        PersonBean row = (PersonBean) richTable.getSelectedRowData();
        //Get the attributes (column) from list
        System.out.println(row.getName());
    }

Now check this -

 Output on console :)

Get single/multiple selected row on a button click (ActionEvent)-

Set table RowSelection to multiple and select multiple row using Ctrl key of your keyboard
and check this code to get multiple selected row using RowKeySet, We can get all row using getSelectedRowKeys method

import org.apache.myfaces.trinidad.model.RowKeySet;
import java.util.Iterator;    



/**Method to get all selected record in af:table
     * @param actionEvent
     */
    public void getSelectedRecord(ActionEvent actionEvent) {
        //getTableBind is binding of table on page.
        RowKeySet selectedEmps = getTableBind().getSelectedRowKeys();
        //Create iterator from RowKeySet
        Iterator selectedEmpIter = selectedEmps.iterator();

        while (selectedEmpIter.hasNext()) {
            String i = selectedEmpIter.next().toString();
            //personList is the list used to populate table and name is a column of table
            //So here filter list using index and get values then
            PersonBean rowIter = personList.get(Integer.parseInt(i));
            System.out.println(rowIter.getName());
        }
       
    }

Now run and check again -

 Output on console :)
