Description: Distributed applications, devices, and services appear in many different arrangements in an
enterprise. At your company, you probably access data from your intranet services, from
computers distributed throughout the company network, and from services across the firewall out
on the Web. For example, you might access a calendar-sharing application or a financial
application to fill out expense sheets. Someone must maintain all these applications. Not only the
applications, but also the hardware that supports them must be maintained. Resource management
encompasses both applications and hardware. In fact, both application and hardware management
can be supported through the development of Java Management Extensions (JMX) resource
management software. This book will show how you can use JMX to manage and monitor all
your resources across an enterprise—both software and hardware.

Description: 文件传输协议FTP是基于TCP / IP的应用层协议,其主要功能是提供文件的共享、支持远距离计算机间接或直接连接、保护用户不因各类主机文件存储器系统的差异而受影响、进行可靠且有效的数据传输等,应用非常广泛。但是传统的FTP有不少的安全漏洞,例如明文传输、缺乏对数据的机密性和完整性保护,对通信双方也没有可靠的认证措施等。针对FTP的安全漏洞,近年来也出现了一些不需要对F IP协议自身做完全更改的协议扩展模块,如FTP SSL /TLS Extension。SSL ( Secure Sockets Layer)是用于对TCP / IP数据流进行加密的协议,同时还包括了身份认证和数据完整性校验等内容。显然,基于SSL /TLS的FTP克服了明文传输的致命弱点,但是无可否认的是,在开放式的互联网环境下FTP服务器受到恶意攻击的可能性还是很大,而且协议数据的安全性还是未得到保障。安全的本质是在信息的安全期内保证其在网络上流动的或
者静态存放时不被非授权用户非法访问,但授权用户却可以访问。基于这一概念,本文在SSL 的基础上设计了一个安全FTP系统,从认证、传输、存储三个方面大大提高了FTP的安全性。-FTP File Transfer Protocol is based on TCP/IP application layer protocol, its main function is to provide file sharing, remote computer support to connect directly or indirectly, to protect users from all types of hosts file memory system affected by the difference between, for reliable and effective data transmission and so on, a wide range of applications. Traditional FTP but there are a lot of security vulnerabilities, such as express delivery, lack of data confidentiality and integrity protection, the two sides of the communication did not credible certification measures. FTP for security vulnerabilities in recent years, there have been some F IP protocol does not need to completely change their agreement to do the expansion modules, such as FTP SSL/TLS Extension. SSL (Secure Sockets Layer) is used for TCP/IP data stream is encrypted agreement also includes authentication and data integrity checking and so on. Obviously, based on SSL/TLS for FTP transmission to overcome the Platform: |

Description: 在众多的计算机应用中，有一类重要的计算机应用，称为数据密集型应用，例如，管理信息系统、办公信息系统、银行信息系统、民航定票系统、情报检索系统等，这是最大的计算机应用领域，管理这种大量的、持久的、共享的数据需要数据库技术。
JDBC是Sun提供的一套数据库编程接口，由Java语言编写的类、界面组成。用JDBC编写的程序能够自动地将SQL语句传送给相应的数据库管理系统，而且通过使用JDBC，开发人员可以很方便地将SQL语句传送给几乎任何一种数据库。也就是说，开发人员可以不必写一个程序访问Oracle，写另一个程序访问MySQL，再写一个程序访问SQL Server。
使用Java编写的应用程序可以在任何支持Java的平台上运行，Java和JDBC的结合可以让开发人员在开发数据库应用程序时真正实现“一次编写，处处运行！”。
-In many of the computer application, have a kind of important computer application, called data intensive applications, for example, the management information system, office information system, bank information system, civil aviation booking system, such as information retrieval system, this is the biggest computer application field, manage this a lot of, lasting, sharing of data to database technology.
JDBC is a set of Sun provide database programming interface, written by the Java language classes, interface component. Use JDBC programming can automatically will send it to the corresponding SQL database management system, and by using JDBC, developers can very conveniently the SQL statement sent to almost any kind of database. That is, the developers can don t need to write a program to visit Oracle, write another program access MySQL, to write a program to visit SQL Server.
Use Java write applications can be in any support Java on the platform of the operation, Java and JDB Platform: |
