Step-by-Step Procedure
This section describes all the steps necessary for migrating custom portal applications .
4.1
Sample Application
To illustrate these steps, we use a sample application com.myCompany.MigrationTest, developed
and deployed in a SAP NetWeaver 7.0x portal.
The application looks as follows:
When the application is loaded, the title displays the full name of the current user: “Hello <user
name>”. Entering the user ID and clicking OK displays the full UME ID and navigation tree of the user
with active links.

4.3
Updating JAR Locations for Build Time
In SAP NetWeaver 7.3, the public APIs are packaged in JAR files, that are now stored in different
locations. To ensure that your application has access to the public APIs it uses, you need to update
the locations of the JAR files in your project.
In the application code, you can see the import errors that result from the change of location of the
public JARs.
To resolve these errors, perform the steps described in the following sections.
4.3.1 Finding Public APIs JARs
1. In the NWDS installation folder, open the plugins subfolder, and check for all the plugins
(JARs) that start with com.sap.tc.ap.*
Each of these files represents an SCA and contains the public API JARs. The name pattern of a
JAR file is com.sap.tc.ap.<sca name>_<version number>.jar.
There may be more than one version for each SCA, of which you should use the latest.
2. Open a JAR and set the display option to Flat Folder View.
The JARs are located under
SCA>\DCs\sap.com\tc\<comp>\<app>\api\_comp\gen\default\public\api\lib\java.
3. In your file system, create a folder in which you want to store the public APIs.
4. In this folder, create a subfolder with the name <comp>_<application>.
5. Copy all the required JARs into this subfolder.
For example:
1. Open com.sap.tc.ap.epruntime_7.3.0.111019142240.jar.
2. Locate com.sap.portal.navigation.api_service.jar under EPRUNTIME\DCs\sap.com\tc\ep\navigation\api\_comp\gen\default\public\api\lib\java,
and copy it to the ep_navigation subfolder.
Repeat these steps for all required JARs.

4.3.2 Finding Relevant JARs for Imported Classes
1. In the Javadocs section at SAP Help Portal, choose the relevant version of SAP NetWeaver
7.3, and then Enterprise Portal.
2. Find an imported class, for example, AbstractPortalComponent, and open the link.
3. Under Access Rights see the location of the JAR: in EP-BASIS-API under ..../epbc/prt/api/...
4.3.3 Adding JARs
1. In NWDS, right-click the project and choose Properties.
2. In the Properties dialog, choose Add External JARs.
3. Select tc~epbc~prt~api.jar in the epbc_prt folder, and choose OK.
4. Verify that the class references are now resolved, since all
com.sapportals.portal.component* APIs are included in the same JAR.
February 2012

How To... Migrate Custom Portal Applications to SAP NetWeaver 7.3
5. Repeat the above steps to resolve com.sap.portal.navigation* by adding
com.sap.portal.navigation.api_service.jar, and com.sapportals.htmlb* by adding
com.sapportals.htmlb.jar, located under FRAMEWORKEXT\DCs\sap.com\com.sapportals.htmlb\_comp\gen\default\public\default\lib\java.
4.4
Handling Deprecated APIs
Deprecated means that, although an API is still available and supported, it will be phased out in the
subsequent releases, therefore you should avoid using it, and use the suggested alternative API.
We recommend using the new 7.3 reference DC in the new projects.
1. Repeat the steps described in the previous section for
com.sapportals.portal.prt.service.usermanagement.IUserManagementService.
In the Javadoc for the IUserManagementService interface, you can see that it is deprecated
and replaced by the IUserManagementEngine interface, located in the
com.sap.ip.portal.service.ume package.
2. In the imports statement, replace
com.sapportals.portal.prt.service.usermanagement.IUserManagementService
with com.sap.ip.portal.service.ume.IUserManagementEngine.
3. Add the JAR com.sap.portal.usermanagement.jar from EP-BASIS, as described above.
4. In your code, make the necessary changes where this interface is used.
For example:
1. Replace all IUsermanagementService with IUserManagementEngine.
There is still an error with com.sapportals.portal.security.usermanagement.IRoleFactory.
2. Check the Javadocs at
http://help.sap.com/javadocs/NW73/SPS05/CE/se/com.sap.se/index.html
for IRoleFactory under com.sap.security.api. You need to replace
com.sapportals.portal.security.usermanagement.IRoleFactory
with com.sap.security.api.IRoleFactory and import com.sap.security.api.IRoleFactory
instead of com.sapportals.portal.security.usermanagement.IRole.
February 2012

How To... Migrate Custom Portal Applications to SAP NetWeaver 7.3
3. Set a reference to the relevant tc~je~usermanagement~api.jar under ENGFACADE.
4. To resolve IRole, add the imports com.sap.security.api.IRole statement.
5. The strikethrough on UserManagementException indicates that it is deprecated.
In the imports statement, replace
com.sapportals.portal.security.usermanagement.UserManagementException with
com.sap.security.api.UMException.
Replace UserManagementException with UMException from com.sap.security.api.
6. Use the NWDS quick fix to replace the unidentified method role.getUMEID() with
getUniqueID().
4.5
Adjusting Code to Support JDK 1.6
SAP NetWeaver 7.3 uses JDK 1.6, which means that all custom code should comply with the
JDK 1.6 standard.
In the imports list, there are errors for the com.sapportals.htmlb.enum* objects,
because enum is a reserved word in JDK1.6. It should be replaced with
com.sapportals.htmlb.enums*, and all instances of enum in the code should be replaced
with another string, for example, enum1.
4.6
Setting Runtime Dependencies in Portalapp.xml
Make sure that the application descriptor, portalapp.xml, located under dist PORTAL-INF,
complies with the standard defined in Deployment Descriptor (portalapp.xml).
In our example, portalapp.xml looks as follows:
<application>
<application-config>
<property name="PrivateSharingReference"
value="com.sap.portal.htmlb, com.sap.portal.navigation.service,
com.sap.portal.navigation.api_service"/>
<property name="Vendor" value="mycompany.com"/>
February 2012

How To... Migrate Custom Portal Applications to SAP NetWeaver 7.3
<property name="SecurityArea" value="NetWeaver.Portal"/>
</application-config>
<components>
<component name="MigrationTest">
<component-config
<property name="ClassName"
value="com.my.company.migration.test.MigrationTest"/>
</component-config>
<component-profile/>
</component>
</components>
<services/>
</application>
To enable referencing the portal APIs used in your application, you must define the relevant
PrivateSharingReference and/or PublicSharingReference properties. In SAP NetWeaver 7.3,
references should be made via the facade DC rather than directly to the components..
For portal applications you should convert the DC name to reference.
For example, if the DC name in the Javadocs is [sap.com] tc/epbc/prt/api, the reference
should be com.sap.tc~epbc~prt~api. For a J2EE library, the prefix should be SAPJ2EE::library:.
Portalapp.xml in our example should look as follows:
<application>
<application-config>
<property name="PrivateSharingReference"
value="com.sap.tc~epbc~prt~api,
SAPJ2EE::library:com.sapportals.htmlb,
com.sap.tc~ep~navigation~api"/>
<property name="Vendor" value="mycompany.com"/>
<property name="SecurityArea" value="NetWeaver.Portal"/>
</application-config>
<components>
<component name="MigrationTest">
<component-config
<property name="ClassName"
value="com.my.company.migration.test.MigrationTest"/>
</component-config>
<component-profile/>
</component>
</components>
<services/>
</application>

4.7
Building and Deploying Application
After resolving all errors, build your application and create a deployable object (EAR).
Note
If you are using NWDI, the process is different. For more information, see Migrating Tracks
Content from SAP NetWeaver 7.0 to a Higher Version.
1. Right-click the project and select Export.
2. Select SAP NetWeaver Portal
EAR File and choose Next.
3. Select the project from the list and choose Next.
4. Define the Name and Location properties and choose Next.
5. Verify that the EAR file is created in your project.
Deploy the application and verify there are no deployment errors.
1. To configure the 7.3 NetWeaver Portal Server for deployment, go to Window
SAP AS JAVA.
2. To open the Deploy View, go to Window Show View Deploy View.
3. Add the EAR file you have created, and deploy it.
4. Verify that deployment completed successfully (with no errors or warnings)
Preferences
For more information about deployment of applications, see Application Lifecycle and Deployment.

4.8
Testing Application at Runtime
Following the successful deployment, test your application at runtime and verify that its
behavior is the same as in NetWeaver 7.0.
1. Log on to the portal as a Content Administrator, and navigate to Content
Administration Portal Content Management.
2. Choose Portal Applications to open the GPAL repository.
3. Right-click the deployed application, and choose Preview.
Verify that the application functions as expected.
Note
If the application requires parameters, it will not run properly in preview. You need to
create a wrapping iView by copying the application into the PCD, and set the required
parameters.
For more information, see Working with GPAL Repositories.
