Hi,

I am using Spring MVC pattern in my application.I am facing small issue to load file content in dropdown list in jsp.

when i click button to get devices its loading into dropdown but not proper (its going to main page due to c:url tag).
could any body suggest is there any mistake i am doing to load devices in my jsp

//controller class code
public ModelAndView loadDevices(HttpServletRequest req,HttpServletResponse resp){
		System.err.println("DashboardController in loadDevices");
		ModelAndView mav=setDefaultMav();
		ArrayList<String> deviceList=new ArrayList<String>();
		String filePrefix=dbProps.getFilePrefix();
		try{
		 //FileInputStream fstream = new FileInputStream("/apps/InCharge8/CONSOLE/smarts/tomcat/webapps/Dashboard/WEB-INF/classes/AAN");
			System.out.println("value of filePrefix is :::"+filePrefix);
			FileInputStream fstream = new FileInputStream(filePrefix+"/AAN/AAN");
		    // Get the object of DataInputStream
		    DataInputStream in = new DataInputStream(fstream);
		        BufferedReader br = new BufferedReader(new InputStreamReader(in));
		    String strLine;
		    //Read File Line By Line
		    while ((strLine = br.readLine()) != null)   {
		      // Print the content on the console
		      int ind1=strLine.indexOf("+");
		      int ind2=strLine.indexOf("#");
		      strLine=strLine.substring(ind1+1, ind2);
		      deviceList.add(strLine);
		      System.out.println ("device name is::"+strLine);
		    }
		    //Close the input stream
		    in.close();
		    }catch (Exception e){//Catch exception if any
		      System.err.println("Error: " + e.getMessage());
		    }
		    currPerspective.setDeviceList(deviceList);
       return mav;
	}
