Getting DB Connection in Bean/Servlet

By
Using the following method you will get the connection in your Bean/Servlet for your requirement.
For this you just need one parameter from your Server that is the DataSource Name.

use the following code in your  Bean/Servlet


import javax.naming.Context;
import javax.naming.InitialContext;

private Connection getDBConnection() {
        Context ctx;
        Connection conn = null;
        try {
        ctx = new InitialContext();
        DataSource ds;
        ds = (DataSource)ctx.lookup("java:comp/env/jdbc/xyzDS");
        conn = ds.getConnection();
        } catch (Exception e) {
        // TODO: Add catch code
        e.printStackTrace();
        }
        return conn;
    }

xyzDS -> is the DataSource Name.

Passivation and Activation in ADF (Application Module )

By
1. For performance reasons, ADF keeps a pool of application modules in memory. It tries to give each session the same application module as the session used during the last request; however, this might not be possible during peak load of your application. 2. In this case, ADF saves the application modules state in a database table so the application module can be used by another session. This is called passivation . 3. When the first session needs the application module again, its state is retrieved from the database process known as activation . 4. If you have made an error in your code and depend on some variable that is not persisted correctly when your application module state is stored, you will experience mysterious errors under high load.   Enable/Disable Application Module Pooling : Right-click on your application module, choose Configurations.By default, each application module has two configurations. Ensure that the one ending in …Local is selected and then c...

Get modified rows from Entitiy Cache

By
To get the modified rows from entity cache we have getEntityState() method at EntityImpl class. Refer to my previous blog  Accessing EO impl methods from VO impl  where i am overriding the getEntityState() in EOimpl and calling it in VOImpl. We can use methods written or overridden in VOImpl class to AMImpl class. There are different states associated with an entity object. STATUS_UNMODIFIED STATUS_MODIFIED STATUS_NEW STATUS_DELETED STATUS_DEAD We have to check the state or row in our AmImpl class by using the VOImpl method and through this we can distinguish the rows present at vo. Add below code in AMImpl class along with my previous post. public void geCachedRowsCount(){         JobsVOImpl jobsVo = (JobsVOImpl)this.getJobsVO();         RowSetIterator iter = jobsVo.createRowSetIterator(null);             while(iter.hasNext()){             Row row = iter....
