How to get documents from SAP KM in java

Question

Hi Everyone
                I want to get  the SAP KM data to a simple java class......I am able to get this with servlet but i want not a servlet but a simple java class that can get the Documents stored in SAP KM repository..................
I am thinking of using any java Driver in some code like
Class.forName ("com.sap.dbtech.jdbc.DriverSapDB");
                    String url = "http://host name :port";
                    Connection con = DriverManager.getConnection (url, "", "");
                    Statement stmt = con.createStatement ();
               IUser serviceUser = WPUMFactory.getServiceUserFactory().getServiceUser("cmadmin_service");
               ResourceContext c = new ResourceContext(serviceUser);
               IResource r = ResourceFactory.getInstance().getResource(RID.getRID("/documents/Public Documents/"), c);
               System.out.println("Current user   "+r.getContext().getUser().getDisplayName());
               System.out.println("Current user  : "+r.getContext().getUser().getDisplayName());
               System.out.println("Access RID  : "r.getAccessRID().toString()"<br>");
But the above code is giving an exception---java.sql.SQLException: No suitable driver
Can anyone tell me the suotable Lava driver to access SAP KM repository..Or any simple java code that can connect to SAP KM...
Waiting for Ur reply
Thanks & Regards

I am not sure why you need a JDBC driver for doing that.. You can get it using the following itself. If you have a DB only repository, the underlying API of KM will make the DB connection for you and get the content.
Here is what you should be doing
         IUser serviceUser = WPUMFactory.getServiceUserFactory().getServiceUser("cmadmin_service");
         ResourceContext ctx = new ResourceContext(serviceUser );
         RID resRid = RID.getRID("<yourfilepath>");
         IResource resource = ResourceFactory.getInstance().getResource(resRid, ctx);
         //Finally you can read the stream from the resource
         resource.getContent().getInputStream();
