ADF BC : Default Value for Attribute

If you want assign default value to attribute when creating row in ADF BC then do the following.

I am explaining with temporary field.

Create DefaultValAttr in EO and Set the Literal to default value 1. This can be any attribute EO Attribute , Transient etc.

So when you create a row in EO then this attribute will have value 1.

Add this attribute to VO

When I created the row ,it assigned 1 to defaultvaluettr , this applied to any type of attribute.

ADF : Load Customer Specific Properties file in Application Scope

When software application is delivered or deployed on customer site then for each customer there is different setting.

Some architect use Database , Properties file or Some other method.

Here I am going to demo you how to use properties file.

Create General project in jdeveloper as below.

- Create Java File to read properties

- Create properties file in resource directory

Enter following content in properties file.

Write following java code and Run.

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
public class LoadProperties {
    public static void main(String[] args) throws IOException {
        Properties props = new Properties();
        InputStream st =
            Thread.currentThread().getContextClassLoader().getResourceAsStream("MyApp.properties");
        props.load(st);
        System.out.println(props.getProperty("CUST_CURRENCY"));
        System.out.println(props.getProperty("CUST_LANG"));
        System.out.println(props.getProperty("CUST_CITY"));
    }

ADF : Clean Table Filter Using Command Button

ADF Table and Form are the most used component by developer for day to day job. However , ADF Table component is out of box and there are various way we can customize to meet our requirement.

There is one of feature of ADF Table called in-build filter. However , For each column we have to press enter to search for our criteria.

After above filtering is done and if we want to clear the filter then we have to manually delete the text for all 3 filter and press enter.

Solution:- To solve this issue I created one button on Panelcollection component and bind action listener to following method and it took care of clearing all 3 value automatically and re rendering old result.

Note:-  I have managed bean with table binding available.

public void clearEmpQbeFilter(ActionEvent actionEvent) {        
    FilterableQueryDescriptor qd = 
                      (FilterableQueryDescriptor)t1.getFilterModel();
    if (qd != null && qd.getFilterCriteria() != null) {
      qd.getFilterCriteria().clear();
      t1.queueEvent(new QueryEvent(t1, qd));            
   }
}

All filter cleared and result re rendered.
