Accessing Portal Runtime from CAF

Question

Hi All,
We're developing Composite appln services (exposed as web services). We now want to access the portal runtime to retrieve system, user mapping information etc.
Accessing PortalRuntime.getRuntimeResources() returns null (within the service mthds) as this web service resides outside the portal runtime.
For now, we created an external library with libraries prtapi.jar, com.sap.portal.ivs.api_landscape_api.jar, com.sap.portal.ivs.api_portalpcm_api, com.sap.portal.ivs.systemlandscapeservice_api. This external library was included in the 'Used DCs' of the above-mentioned Composite Appln service DC. this enables me to compile and deploy the apis.
what would be the best way to obtain a reference to the Portal runtime from this CAF?
Do we need to add references to the following jars in application-j2ee-engine.xml? If so, how can I extend the SAP_SYSTEM_ADD_LIBS variable to show the following jars in the 'Installed libraries' list.
prtapi.jar, com.sap.portal.ivs.api_landscape_api.jar, com.sap.portal.ivs.api_portalpcm_api, com.sap.portal.ivs.systemlandscapeservice_api
Appreciate any pointers on the above. Thanks in advance!

Hi Pankaj,
I am not an expert but probably can still help you out...
I did go through the URL and step 3 is divided in two steps:
1. Making use of enviornment variable to access portal
You can do that by (as mentioned in the URL example below) :
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
            "com.sapportals.portal.prt.registry.PortalRegistryFactory");
InitialContext context = new InitialContext(env);
2. Using the JNDI lookup accessing the portal service you wish to access.
IXSLTransformService xslTransformService =
            (IXSLTransformService) context.lookup(
            "/broker/services/" + IXSLTransformService.KEY);
where KEY is the name of the service, that you wish to access. This service name should be defined in the portalapp.xml file in the format of <application name>.<service name>.
If you have any more questions, please feel free.
Regards and Good Luck,
