It has been a while since I configured it, but what I remember doing was installing the IBM U2 developers kit which then gives you the UCI Editor which allows you to create a datasource in UCI.config.  Then in the Windows datasources you configure DSN that points to the UCI names datasource.

To connect from SQL Server, just did this:
Linked Server: {name you want}
Server type: Other data source
Provider: UniOLEDB Provider
Data source: {name of datasource}
Location: {.DB file name from Universe / Database}

I had this file in my knowledgebase, so may come in handy.

For Java, I extended the asjava.uniobjects.UniSession object from the IBM U2 SDK which has methods to setUserName(String), setPassword(String), setHostName(String), setAccountPath(String) and then here is an example of my methods to login() and logout():
/*
* @see UniSession#connect()
	 */
public boolean login() {
		if(this.isActive()) return true;
		try { 
			this.connect(); 
			return true;		
		} catch(Exception e) {
			System.err.println("\n" + Calendar.getInstance().getTime().toString() + "\n");
			System.err.println(e.getMessage());
			System.err.println("Cause: " + e.getCause() + "\n");
		}
		return false;
	}
/*
* @see UniSession#disconnect()
	 */
public void logout() {
		try { 
			this.disconnect(); 
		} catch(Exception e) {
			System.err.println("\n" + Calendar.getInstance().getTime().toString() + "\n");
			System.err.println(e.getMessage());
			System.err.println("Cause: " + e.getCause() + "\n");
		}
	}
