某些工具方法代码段收集

Check to see if the current operating system is a Windows OS：
public static boolean isWindows()
    {
        return System.getProperty("os.name").indexOf("Windows") != -1;
    }

Check to see if the current Java Virtual Machine is made by Microsoft：
public static boolean isMSJVM()
    {
        return System.getProperty("java.vendor").indexOf("Microsoft") != -1;
    }

HTMLEncode：
public static String HTMLEncode(String s)
    {
        if(null == s)
            return "null";
        StringBuffer stringbuffer = new StringBuffer(s.length());
        for(int i = 0; i < s.length(); i++)
        {
            char c = s.charAt(i);
            if('<' == c)
                stringbuffer.append("<");
            else
            if('>' == c)
                stringbuffer.append(">");
            else
                stringbuffer.append(c);
        }

        return stringbuffer.toString();
    }

Use Ftp：

import两个类：
		import org.apache.commons.net.ftp.FTPClient;
		import org.apache.commons.net.ftp.FTPFile;
		....

		FTPClient ftpClient = new FTPClient();
		try {
			ftpClient.connect(FTP_URL);
			ftpClient.login(FTP_USER_NAME, FTP_PASSWORD);
			ftpClient.changeWorkingDirectory(FTP_CLEAR_QUEST_FOLDER);

			FTPFile[] files = ftpClient.listFiles(CLEAR_QUEST_FILE_NAME);
			if (files.length == 1) {
				FTPFile file = files[0];
				......
			}
			......
		} catch (Exception e) {
			logger.error("retrieve ClearQuest XML faild", e);
			throw new Exception("retrieve ClearQuest XML faild");
		} finally {
			try {
				// Logout from the FTP Server and disconnect
				ftpClient.logout();
				ftpClient.disconnect();
			} catch (IOException e) {
				logger.error(e);
			}
		}

关于读取配置文件的代码，利用java的反射机制，自动实例化和赋值：
代码段：

......
	
	String ftpPropertiesFile = context.getRealPath("**/ftp.properties");
		System.out.println("Loading ftpPropertiesFile variables from file:"+ ftpPropertiesFile);
		Properties m_properties = new Properties();
		m_properties.load(new FileInputStream(ftpPropertiesFile));

		Enumeration enumeration = m_properties.propertyNames();
		Class c = Class.forName("classname");

		while (enumeration.hasMoreElements()) {
			String fieldName = (String) enumeration.nextElement();
			String value = (m_properties.getProperty(fieldName, "")).trim();
			Field field = c.getDeclaredField(fieldName);

			field.setAccessible(true);
			if (field.getType().toString().equals("boolean")) {
				field.setBoolean(c, "true".equalsIgnoreCase(value));
			} else if (field.getType().toString().equals("int")) {
				field.setInt(c, Integer.parseInt(value));
			} 
			......
			else {
				field.set(c, value);
			}
		}
