Step 1. Create a class item
public class Item {
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
Step 2. Create Managed Bean
@ManagedBean(name = "contentController")
@SessionScoped
public class ContentController {
private List<item[]> contentList = new ArrayList<item[]>();
private List<string> columnNames = new ArrayList<string>();
public ContentController() {
columnNames.add("Name");
columnNames.add("Age");
Item[] child = new Item[columnNames.size()];
Item item = new Item();
item.setValue("Alanis");
child[0]= item; //First Row first column
item = new Item();
item.setValue("36");
child[1]= item; //First Row second column
contentList.add(child); //Adding first row
child = new Item[columnNames.size()];
item = new Item();
item.setValue("Sachin");
child[0]= item; //Second Row first column
item = new Item();
item.setValue("39");
child[1]= item; //Second Row second column
contentList.add(child); //Adding second row
}
public List<string> getColumnNames() {
return columnNames;
}
public void setColumnNames(List<string> columnNames) {
this.columnNames = columnNames;
}
public List<item[]> getContentList() {
return contentList;
}
public void setContentList(List<item[]> contentList) {
this.contentList = contentList;
}
}
3. Create the jsf view
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:p="http://primefaces.org/ui"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<body>
<h:form id="form1" >
<p:dataTable id="dataTableContent" var="list" value="#{contentController.contentList}" rowIndexVar="rowIndex">
<p:columns value="#{contentController.columnNames}" columnIndexVar="colIndex" var="item" >
<f:facet name="header">
<h:outputText value="#{item}"/>
</f:facet>
<h:outputText value="#{list[colIndex].value}"/>
</p:columns>
</p:dataTable>
</h:form>
</body>
</html>
