Importing the Project Templates for the Web
Dynpro Tutorial 
Use
This tutorial consists of a Web Dynpro project that calls the EJB methods provided with the J2EE quick car rental application over a Web service. Therefore, before you can begin with the tutorial, you need to import both the project for the car quick rental application as well as the Web Dynpro project. These projects are available in the following packages.
· The J2EE_QuickCarRental project is available with the SAP NetWeaver Developer Studio. It contains the EJB, the dictionary project, and the Web service used by the car rental application.
· The TutWD_CarRental project is the starting point for the Web Dynpro project used in this tutorial.
You can find both of these initial projects in the example directory for the SAP NetWeaver Developer Studio.
In addition, you can also find the completed project on the SDN. This project contains the quick car rental projects and the Web Dynpro project after completion of this tutorial. See Home ® Developer Areas ® SAP NetWeaver Platform ® Security.
Prerequisites
|
|
You know the workspace directory for your SAP NetWeaver Developer Studio. |
|
|
If you have previously worked on either the J2EE quick car rental project or the Web Dynpro car rental applications using the SAP NetWeaver Developer Studio, then these projects are closed and removed from the SAP NetWeaver Developer Studio workspace. |
|
|
You know the path to the examples provided with the Developer Studio. In a default installation this path is C:\Program Files\SAP\JDT\eclipse\examples. |
This tutorial assumes that you are working with the car rental applications as they are provided with initial projects. Therefore, if you have previously worked on either the J2EE or the Web Dynpro car rental applications and deployed them to the AS Java, we recommend you remove them not only from the Developer Studio’s workspace, but also from the AS Java and start with a completely new set of projects. Note the following:
● When deleting the projects from the Developer Studio, also delete the content from the workspace. Also delete the Dictionary project and the Helperclasses. (Switch to the Navigator to make sure that all projects have been removed.)
● To remove the applications from the AS Java, use the Deploy service in the Visual Administrator. Remove the applications sap.com/QuickCarRentalEar and local/TutWD_CarRental and any of their corresponding components.
● You do not need to remove any entries from the database itself.
Procedure
Importing the project templates into the SAP NetWeaver Developer Studio
...
1. Navigate to the location of the examples for the SAP NetWeaver Developer Studio.
2. Unpack the J2EE_QuickCarRental.zip and WebDynpro_CarRental.zip archives into the workspace directory for the Developer Studio.
3. Start the SAP NetWeaver Developer Studio.
4. Switch to the J2EE Development perspective and import the projects from the quick car rental application.
a. To switch to the J2EE Development perspective, choose Window ® Open Perspective ® J2EE Development.
b. Choose File ® Import.
c. Select Multiple Existing Projects into Workspace and choose Next.
d. In the Select base folder field, enter your workspace directory (or use the Browse... function).
The projects for the car rental application appear. These are Helperclasses, J2EE_QuickCarRentalEar, J2EE_QuickCarRentalEjb, J2EE_QuickCarRentalWeb, QuickCarRentalDictionary and TutWD_CarRental.
e. Select all of these projects. Also select the Open projects after import indicator and choose Finish.
The projects are opened in the SAP NetWeaver Developer Studio.
Depending on your settings, you may receive warnings that apply to the Web Dynpro project. You can ignore these warnings.
5. Deploy the dictionary archive to the AS Java.
a. Switch to the Dictionary perspective. (Choose Window ® Open Perspective ® Dictionary.)
b. Choose the Dictionary Explorer.
c. Select the QuickCarRentalDictionary project, open the context menu with the right mouse button, and choose Deploy.
If this is the first time you deploy from the SAP NetWeaver Developer Studio, then you are prompted for the SDM password. Enter this password to continue with deployment.
6. Deploy the EAR archive to the AS Java.
a. Switch back to the J2EE Development perspective and the J2EE Explorer.
b. Expand the J2EE_QuickCarRentalEar project.
c. Select the J2EE_QuickCarRentalEar.ear node, open the context menu and choose Deploy to J2EE Engine.
7. Deploy the Web Dynpro project to the AS Java.
a. Switch to the Web Dynpro perspective.
b. Expand TutWD_CarRental ® Web Dynpro ®Applications.
c. Select the CarRentalApp node, open the context menu and choose Deploy New Archive and Run.
The Web Dynpro car rental application starts.
If the application does not run, then make sure the AS Java and the SDM are running and that the host and port are correct. Also make sure that the host and port are correct in the model for the Web service (under TutWD_CarRental ® Web Dynpro ® Models ® CarRentalModel ® Logical Ports ®Config1Port_Document).
