Press F8 to run the naming service class. If you Display cl_wdy_wb_naming_service class, you will see that it has a static method named GET_CLASSNAME_FOR_COMPONENT which is used for to supply the implementation class for a Web Dynpro component. Performance and scalability should be the major criteria while choosing between Webdynpro JAVA and Webdynpro ABAP.Call transaction SE24 Class Builder: Initial screen tcode.Īnd enter the class name CL_WDY_WB_NAMING_SERVICE in the Object Type input area. So if the number of users are large, its better to go for Webdynpro JAVA and if the number is medium or manageable, you can go for Webdynpro for ABAP. But the ABAP server is yet to prove its credential as a reliable Web Server. Webdynpro JAVA runs on sun’s proven web server (J2EE engine) which can support large number of web users at a time. Webdynpro ABAP uses the same Transport Management system as R/3, so there is no need to maintain parallel Transport Management system which is the case in Webdynpro JAVA. In webdynpro JAVA as each developer is checking out and checking in the code, there are chances of conflicts. Webdynpro ABAP has much more powerful Version control system than Webdynpro JAVA as the code is stored centrally in the server. Other main difference in Webdynpro ABAP is that code is stored centrally in the ABAP server, so it relieves the load from developer’s client machine where code is stored in the case of Webdynpro JAVA. This Custom controller can be used within other controllers to read and update data.

Context of this controller will be generated based on the import – export parameters of BAPI or Web Service. In Service Call a wizard creates a custom controller based on the BAPI or Web Service that we give. Webdynpro ABAP gives new option called Service Call. The instance of this class should be used as model within the component and this is the proper design. But we still have the option of defining an ABAP class which helps to read data and save data back to table. In fact there is no option for model available in the Graphical tool set to develop Webdynpro ABAP application. The main difference between Webdynpro JAVA and Webdynpro ABAP is that Model doesn’t have much significance in Webdynpro ABAP. What is the difference between Webdynpro JAVA and Webdynpro ABAP? Both Webdynpro ABAP and Webdynpro JAVA applications are run in the Enterprise Portal. It also has a graphical interface tool that is integrated with the ABAP Workbench (Transaction Se80). Everything about Webdynpro ABAP is same as Webdynpro JAVA, except that it uses ABAP as programming language instead of JAVA. Webdynpro for ABAP and Webdynpro JAVA use the same declarative metamodel concept based on MVC pattern to create web applications.
