Read Business Systems from SLD through Java Application

[Former Member]

This blog discusses the method to read the list of business systems created on SLD through the Java application. The origin of this idea is to read the existing Bussiness system from SLD and send it along with the message to XI. Based on this business system it routed the message to my back end system.

Pre-requisite:

Include the following jars in the application build path for client side compilation.
1.lcrclient.jar
2.sldserv.jar 

Use the following services in application-j2ee-engine.xml.

<?xml version="1.0" encoding="UTF-8"?>\ <!DOCTYPE application-j2ee-engine SYSTEM "application-j2ee-engine.dtd">\ <application-j2ee-engine>\ \     <reference  \ \     \     reference-type="weak">\ \     \     <reference-target  \ \     \     \     provider-name="sap.com"  \ \     \     \     target-type="service">tc/sld/dp/j2ee</reference-target>\ \     </reference>\ \     <reference  \ \     \     reference-type="weak">\ \     \     <reference-target  \ \     \     \     provider-name="sap.com"  \ \     \     \     target-type="service">tc/sec/securestorage/service</reference-target>\ \     </reference>\ \     <reference  \ \     \     reference-type="weak">\ \     \     <reference-target  \ \     \     \     provider-name="sap.com"  \ \     \     \     target-type="interface">tc/sec/destinations/interface</reference-target>\ \     </reference>\ \     <reference  \ \     \     reference-type="weak">\ \     \     <reference-target  \ \     \     \     provider-name="sap.com"  \ \     \     \     target-type="service">tc~sec~destinations~service</reference-target>\ \     </reference>\ \     <reference  \ \     \     reference-type="weak">\ \     \     <reference-target  \ \     \     \     provider-name="sap.com"  \ \     \     \     target-type="service">sld</reference-target>\ \     </reference>\ \     <reference  \ \     \     reference-type="weak">\ \     \     <reference-target  \ \     \     \     provider-name="sap.com"  \ \     \     \     target-type="library">com.sap.lcr.api.cimclient</reference-target>\ \     </reference>\ \     <reference  \ \     \     reference-type="weak">\ \     \     <reference-target  \ \     \     \     provider-name="sap.com"  \ \     \     \     target-type="library">com.sap.lcr.namealloc</reference-target>\ \     </reference>\ \     <provider-name>sap.com</provider-name>\ \     <fail-over-enable  \ \     \     mode="disable"/>\ </application-j2ee-engine>\

Code Sample:

The following code will pick up all the business systems existing on SLD. The rights of the administrator is necessary to pick up the systems from SLD.

public void getAllBusinessSystems() \     { \         InputStream is = \             ClassLoader.getSystemResourceAsStream( \                 "apps/sap.com/ ReadBusinessSystem /servlet_jsp/ReadBusinessSystem/root/WEB-INF/properties/YourProp.properties"); \         Properties getProps = new Properties(); \         try \         { \             getProps.load(is); \         } \         catch (IOException ioe) \         { \             System.err.println("getAllBusinessSystems Exception : " + ioe.getMessage()); \         } \         Properties props = new Properties(); \         props.put(Context.INITIAL_CONTEXT_FACTORY, getProps.getProperty("INITIAL_CONTEXT_FACTORY")); \         props.put(Context.PROVIDER_URL, getProps.getProperty("PROVIDER_URL")); \         props.put(Context.SECURITY_PRINCIPAL, getProps.getProperty("SECURITY_PRINCIPAL")); \         props.put(Context.SECURITY_CREDENTIALS, getProps.getProperty("SECURITY_CREDENTIALS")); \         Context jndiContext = null; \         Vector businessSystems = new Vector(); \         Vector applicationSystems = new Vector(); \         try \         { \             jndiContext = new InitialContext(props); \             // Get a reference to the naming service \             SldApplicationServiceInterface srvContext = (SldApplicationServiceInterface) jndiContext.lookup(SldApplicationServiceInterface.KEY); \             CIMOMClient cimomClient = srvContext.getCimClient(); \             CIMClient cimClient = new CIMClient(cimomClient); \             SAP_BusinessSystemAccessor businessaccessor = new SAP_BusinessSystemAccessor(cimClient); \             //List of Systems \             SAP_BusinessSystem[] businessaccessorBusinessnames = businessaccessor.enumerateSAP_BusinessSystemInstances(); \             for (int i = 0; i < businessaccessorBusinessnames.length; i++) \             { \                 SAP_BusinessSystem businessSysName = businessaccessorBusinessnames[i]; \                 SDAccess access = new SDAccess(cimClient); \                  \                 System.err.println("Business System Name : " + businessSysName.getCaption_WT()); \             } \         } \         catch (Exception e) \         { \             System.err.println("getAllBusinessSystems Exception : " + e.getMessage()); \         } \     }

Properties File(YourProp.properties):

INITIAL_CONTEXT_FACTORY = com.sap.engine.services.jndi.InitialContextFactoryImpl \ PROVIDER_URL = server:50104 \ SECURITY_PRINCIPAL = UserName \ SECURITY_CREDENTIALS = Password

Note:

Steps to grant permission to your application to access SLD:

Step 1 : Go to Visual Administrator and check the SLD Data Supplier link under services.
Step 2 : Go to “CIM client Generation Settings” and grant domain permissions to the project module.
Step 3 : Perform the CIMClientTest and if successful the process is complete.
