执行远程服务器的系统命令并获取内容：

boolean isAuthenticated = connection.authenticateWithPassword(user, password);

	
			logger.info("Connecting to " + ip + ":" + port + "successful");

			Session sess = connection.openSession();

			sess.execCommand("/usr/local/squid/bin/rotateBilling.sh -v");

			InputStream stdout = new StreamGobbler(sess.getStdout());

			BufferedReader br = new BufferedReader(new InputStreamReader(stdout));

			StringBuffer sb = new StringBuffer();
			while (true) {

				String line = br.readLine();
				if (line == null)
					break;
				sb.append(line);

			}
			if (sb.toString().indexOf("0.0.4") < 0) {
				sess.close();
				connection.close();
				logger.error(selectdev + ":" + dev_name + ":" + ip + ":" + errortime
						+ ": shell file version isn't 0.0.4");
				return;
			}
			sess.close();

您好，我使用Orion SSH2执行启动Tomcat的命令，提示需要JRE_HOME或JAVA_HOME，但是这环境变量已配置，且我通过SSH Secure Shell却可以启动成功。是不是Orion SSH2执行的命令不能识别环境变量，如何解决？多谢。
