In this post I am trying to show how we can create a node in Oracle Data Relation Ship Management using in build API’s for DRM . Before proceeding for actual development we need to make our project ready so that it will able to get all In build API’s. First of all we need to download Oracle DRM SDK using below link http://www.oracle.com/technetwork/middleware/bi-foundation/downloads/hyperion-data-relationship-111120-089726.html. DRM sdk provides below artifacts
Figure 1 but we need only jar files belongs to dist/lib and thirdparty to create below libraries for our Jdeveloper Project. Jdeveloper 11.1.1.3 is the IDE I am using for developing the project.
Figure 2 where library “Thirdparty” contains below jar files.I prefer those jar files needs to be copied to project folder, I mean from DRM SDK zip file (from figure 1) to project folder.
DRMAPI library contains dist/lib/hdrm-proxy-api.jar and xerces library contains thirdparty/xerces/xerces.jar. After doing all setups we can move for development.
please follow below code block for adding a node in DRM.
public class AddDRMNode { //declare variables that needs to be initialized and //used through out the class Identify the DRM server //to which we are trying to make request String aUrl = "<Url of DRM server>";
