To get hostname from system alias in SAP Enterprise Portal

[former_member708620]

Hello,

In SAP Portal, we may across scenario where we need to read the host name from system alias. In my case, I need to setup SSO for EPM add-in. I followed the steps given in SAP note: 2148259.In EPM add-in war file, we need to maintain host name in web app. As we have EPM add-in implemented in two SAP backend systems, we could not maintained hostname in web app.

To overcome this challenge, I followed below steps:
1. As EPM add-in is called using an URL, created an URL iview and passed system alias as a URL parameter.

2. In the EPM add-in war file, to read the system alias from URL and then read hostname using it, wrote below code in EPM_AddIn_Launcher.java in "updateParamters" method.

      String hostName =null;

      String sysAlias = request.getParameter("system");

      ISystemLandscape portalLandscape = UMFactory.getSystemLandscapeFactory().getLandscape(ISystemLandscape.TYPE_ENTERPRISE_PORTAL);

      if(portalLandscape == null) {

         throw new Exception("It seems like no Enterprise Portal is installed.");

      }

      ISystemLandscapeObject systemObject;

      try {

      systemObject = portalLandscape.getSystemByAlias(""+ sysAlias +"");

      hostName= systemObject.getAttribute("wap.WAS.hostname").toString().split(":")[0];

      }

As discussed above, using SAP Portal APIs, you can get hostname from system alias using below 3 steps:

1.   ISystemLandscape portalLandscape =              UMFactory.getSystemLandscapeFactory().getLandscape(ISystemLandscape.TYPE_ENTERPRISE_PORTAL)

2. ISystemLandscapeObject systemObject = portalLandscape.getSystemByAlias("system alias name in string format")

3. String hostName= systemObject.getAttribute("wap.WAS.hostname").toString().split(":")[0]

You can use this solution as per your requirement. Make sure system alias you are passing is correctly configured in System Administration--> System Landscape in SAP Enterprise Portal system.
