rosjava: Get List of Parameters

edit

I was able to solve it by going the route of ssh-ing into the host machine (using Jsch). This code did the bulk of the work from an AsyncTask.

            JSch jsch=new JSch();  

            Properties config = new Properties();
            config.put("StrictHostKeyChecking", "no");
            config.put("compression.s2c", "zlib,none");
            config.put("compression.c2s", "zlib,none");

            this.user = params[0];
            this.host = params[1];
            this.pwd = params[2];
            this.cmd = params[3];

            session=jsch.getSession(user, host, 22);   
            session.setConfig(config);
            session.setPassword(pwd);
            session.connect();

            StringBuffer result = new StringBuffer();

            channelexec = (ChannelExec) session.openChannel("exec");
            String setPATH = "source /opt/ros/fuerte/setup.bash;export ROS_PACKAGE_PATH=/home/YOURCOMPNAME/ros_workspace:/opt/ros/fuerte/share:/opt/ros/fuerte/stacks;";
            channelexec.setCommand(setPATH+cmd);//
            channelexec.setInputStream(null);
            //channel.setOutputStream(System.out);
            channelexec.setErrStream(System.err);

            InputStream stdout = channelexec.getInputStream();
            InputStream stderr = channelexec.getErrStream();
            //channelexec.setPty(true);
            channelexec.connect();

            msg = "Connected to Host";
            toastHandler.post(toastRunnable);

            String aux = "";
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(stdout));
            while ((aux=bufferedReader.readLine()) != null) {
                    aux.replaceAll(NodeName,"");
                builder.append(","+aux);
            }    

        }catch(Exception e){
            msg = "Cannot Retrieve Param List";
            toastHandler.post(toastRunnable);
            e.printStackTrace();
        }
        return builder.toString().substring(1);

And the cmd I called was:

String cmd = "rosparam list "+NodeName
