SAP NetWeaver CE 7.2 (SP 03) / CE 7.1 Ehp 1 (SP 03), JDK 1.6/ JDK 1.5, XML, JAXB.

Summary:

In many custom business application we are using CAF Business objects their might be requirement of archive data of CAF Business Objects for auditing and future purposes. Here I am discussing step by step configuration of NetWeaver Scheduler and corresponding custom java coding.

Introduction

In custom composite application for data storing, normally we are using CAF Business Objects. But we required archiving them after certain time of period for auditing or future purposes. For this requirement I have made a custom application via which we can easily archive our CAF BO data and restore them when required to CAF BO. The data archive application will be triggered via NetWeaver Scheduler. The mechanism I have used to do the custom application as follows: a) read the desired CAF BO and generate one xml file with help of JAXB api into the Hard disk of the server and delete the content of the CAF BO b ) then using java util zip api to create one zip file and put the xml file into it and delete the xml file from the hard disk of the server c) and store the name of the CAF BO with actual path where the zip file stored into server into another CAF BO. d) When restore mechanism will triggered from the zip file read the content and data will be back to the actual CAF BO and entry will be delete from the History CAF BO.


Create Projects

For this custom application we required one CAF project. With the name: example/ce/archive

Implementation

CAF Project


To do the CAF project please follow the below instruction.


Steps
Screen Shots

Step 1: Choose File -> New – >

Project of your Netweaver Developer Studio

of CAF perspective.

/wp-content/uploads/2015/01/1_626648.jpg
Step 2: One popup window come and goes to the Development Infrastructure – > Development Component and press next button in the below. /wp-content/uploads/2015/01/2_626649.jpg
Step 3: Then one popup will be come and choose Development Component type: Composite Application. And press next button. /wp-content/uploads/2015/01/3_626650.jpg
Step 4: Then choose the software component type where you are going to create your development component. /wp-content/uploads/2015/01/4_626651.jpg
Step 5: Then another new popup will be come and provide the details as per requirement. /wp-content/uploads/2015/01/5_626652.jpg
Step 6: The press next button and then finish button. It will create a CAF project into your workspace. /wp-content/uploads/2015/01/6_626653.jpg
Step 7: Now our project is ready. /wp-content/uploads/2015/01/7_626654.jpg
Step 8 : Right click on the modeled package /wp-content/uploads/2015/01/8_626655.jpg
Step 9: Now we are going to create a CAF BO with name BOToArchive. /wp-content/uploads/2015/01/9_626656.jpg
Step 10: The go to the Permission tab of CAF BO and unchecked the Permission check Enabled option /wp-content/uploads/2015/01/10_626657.jpg
Step 11: Then go to the structure tab of CAF BO and press the button Edit Main Structure /wp-content/uploads/2015/01/11_626658.jpg
Step 12: The create two fields with name a)Id data type String cardinality 0 -1 b) Value data type xLongText cardinality 0 -1 /wp-content/uploads/2015/01/12_626659.jpg
Step 13: We have to create another CAF BO for storing archive path and CAF BO names. Provide the new CAF BO name : History and create two fields a)Id data type string b)Path data type xLongText /wp-content/uploads/2015/01/13_626660.jpg
Step 14: Now we have to create one Application service with name : DataArchiveApp /wp-content/uploads/2015/01/14_626661.jpg
Step 15: Then one popup will be come and provide the name of the application service. Then press finish button. /wp-content/uploads/2015/01/16_626662.jpg
Step 16: Then it will generate the application service and check the Generate remote Interface option. Under general tab of application service. /wp-content/uploads/2015/01/15_626663.jpg

Step 17: Now we have to create one custom structure for input parameter of delete_ZIP method.

  Structure Name : BODeleteStruct

/wp-content/uploads/2015/01/17_626664.jpg

Step 18: After you create the custom structure it should look like as screenshot.

  Cardinality ; 0 – n

/wp-content/uploads/2015/01/18_626665.jpg

Step 19: Now we have to create custom method to our application service. To do those go to the operations tab of our application service.

Then press the Add button one popup will be come and choose the first radio button with option Custom operation and then provide the name of operation.

  1. data_Archive
  2. restore_DAT_TO_BO

    c. delete_ZIP

/wp-content/uploads/2015/01/19d_626671.jpg

Step 20: Now we are adding two CAF BO objects to our Application service via dependency tab of application service. /wp-content/uploads/2015/01/20_626672.jpg
Step 21: Now we have to create few general java class for archive our data. Please go to the Java perspective and create name : JAXB_Data_Structure with package : com.tcs.jaxb.data.structure /wp-content/uploads/2015/01/21_626673.jpg
Step 22: Now we have to create another java class name : JaxbUtil with lot of methods with package : com.tcs.jaxb.util

Step 23: Now we have to add DC reference to use SAP NetWeaver Scheduler mechanism into our project to do that open the project into component properties and go to the dependency tab and press the add button one popup will be come and chose ENGFACADE[sap.com] and from this tree select tc/je/scheduler/api and press next button and select deploy time and build time options. And press the finish button. /wp-content/uploads/2015/01/23_626674.jpg
Step 24: Now it will come as screenshot. /wp-content/uploads/2015/01/24_626675.jpg

Step 25: Now we have to create Message driven bean for scheduler. Create a message driven bean of name : Example_Shcedule with supper class MDBJobImplementation with destination name : MyDestinations and then press next button and then press the finish button without changing any default configuatraion.

  Package : com.tcs.nw.scheduler

/wp-content/uploads/2015/01/25_626676.jpg
Step 26: Now we have to access the Application service due to that we have to use EJB annotation.

package com.tcs.nw.scheduler;

import javax.ejb.ActivationConfigProperty;

import javax.ejb.EJB;

import javax.ejb.MessageDriven;

import javax.jms.MessageListener;

import com.tcs.example.ce.archive.modeled

.appsrv.dataarchiveapp.

DataArchiveAppServiceLocal;

import com.sap.scheduler.

runtime.JobContext;

import com.sap.scheduler.

runtime.mdb.MDBJobImplementation;

/**

* MessageDriven Bean

implementation class for: Example_Shedule

*

*/

@MessageDriven(

          activationConfig =

{@ActivationConfigProperty( propertyName=“messageSelector”, propertyValue=“JobDefinition=’Example_JobBean'”),

                  @ActivationConfigProperty(

                  propertyName = “destinationType”,

propertyValue = “javax.jms.Queue”

          ) },

          mappedName = “MyDestination”)

public class Example_Shedule

extends MDBJobImplementation implements MessageListener {

    private static final long serialVersionUID =

4485561670312885280L;

    @EJB(name=“com.tcs.example.ce.archive.modeled.

appsrv.dataarchiveapp.DataArchiveApp”)

    DataArchiveAppServiceLocal

dataArchiveAppServiceLocal;

    /**

    * @see MDBJobImplementation

#MDBJobImplementation()

    */

    public Example_Shedule() {

        super();

        // TODO Auto-generated constructor stub

    }

    @Override

    public void onJob(JobContext arg0)

throws Exception {

          // TODO Auto-generated method stub

          dataArchiveAppServiceLocal.dataArchive(); 

    }

}

Step 27: Now we have to create job-defination.xml file into META-INF folder of ejb module of CAF project for searching the job from NetWeaver Administrator.
/wp-content/uploads/2015/01/27_626678.jpg
Step 28: Now we have to make few entries into ejb-j2ee-engine.xml under META-INF of ejb module of CAF project /wp-content/uploads/2015/01/28_626679.jpg
Step 29 : Now we have to create few entries into application-j2ee-engine.xml file under META-INF folder of ear project of CAF for NetWeaver Scheduler <reference reference-type=”hard”><reference-target target-type=”service” provider-name =”sap.com”>scheduler~runtime</reference-target></reference> and under module we should include below tag<entry-name>jar file of ejb module </entry-name> and <container-type>scheduler~container</container-type>

Step 30: Now we have to write our Application service implementation methods.

Below are the methods we are going to implement.

  1. data_Archive
  2. restore_DAT_TO_BO

    c. delete_ZIP

Step 31: Now we have to deploy our project to SAP Application server.

  1. Generate
  2. Build

    c. deploy

/wp-content/uploads/2015/01/31_626681.jpg

Step 32: After deployment we have to go CAF service browser to insert few data to our BO.

  BO : BOToArchive
