2、d graduates, entrepreneurship and other. At the same time with JSP engine, Oracle established the information interactive website as the background database server; it will improve the efficiency and quality of the traditional employment information. At the same time, the paper introduces implementa
3、tion of enterprise SMS platform using a GSM module, including the hardware environment, the SMS server software architecture, function and design. The scheme realizes the information exchange between students, teachers, and parents, through the practical operation, proved that the system has good pr
4、acticability, solves many problems that exist in the employment information service, it has less demanding on the hardware, the realization of a simple, two times the development of convenient features. 2Keywords: employment platform; network; JSP engine; Oracle database; SMS platform 0 Introduction
5、s Many colleges and universities establish employment column in their own campus network. It provides some enterprises employing demand and job interview skills that offer great help for the employment of graduates. The employment Webpage can be said to be internal and external recruitment extension
6、 or other traditional talent market institutions or affiliated. But also has the following problems: online employment guidance and employment is still in the traditional way of job placement stage. About how to guide graduates self understanding, potential development, system of students occupation
7、 development planning and evaluation, decision-making ability, on the understanding of the world and occupation to occupation information such as strong relates to not ignore, expanding employment channels and entrepreneurship guidance. As a special kind of information carrier for mobile phone text
8、messages, it has special advantage: short, cheap, easy to save and intuitive mass function, so it is very popular. In practical application, construction of SMS platform has two main ways 1. One is the SMS platform server is connected to 3the mobile communication network, the mobile gateway to send
9、and receive text messages. This method need the cable directly access the mobile operators network, due to various constraints and application process of complex factors, does not meet the design requirements. Another way is to use AT commands to control GSM module to send and receive text messages.
10、 The GSM module sends short message service center in the wireless way communication, which will send text messages to mobile terminal users, or received from the mobile terminal message. This way to the hardware requirements are not high, simple to implement, and by setting the status report, also
11、can learn the user whether the mobile terminal receives the message. This way is more feasible scheme of SMS platform construction. In view of the above two reasons, the paper establish network using new JSP technology to realize, the establishment of specialized electronic professional employment w
12、ebsite, it is the focus of improving graduates personal business ability, employment information channels to expand graduates and encourage students to entrepreneurship. At the same time, established a SMS aided office system, the use of SMS notification, event reminders to meet the needs of daily o
13、ffice news. 41 System design and security management The system is a campus information service system based on Web, the purpose is, in order to increase the amount of information and information exchange rate that will be change the form of traditional campus information and enterprise information.
14、 Its structure and function is as shown in figure 1. 1) Campus recruitment information. The characteristics of campus recruitment information is the largest building in micro LAN, the school announced campus recruitment information, followed by the release of employment policy information, paste bar
15、 finally all recruitment information, whether students or the enterprise can publish recruitment information. 2) Network. This part aims to change the traditional family education service charges, encourage students to start their own business, achieve both parents and students choose to each other,
16、 so that both sides are satisfied. 3) The book trade. The so-called “recycling“ is to encourage students to register themselves do not read the book online, exchange, lease or sale of form, form the network book market, improve the utilization rate of some teaching materials and reference books, to
17、maximize the use of Library resources. 54) Other information bar. To facilitate students to organize their own activities and announce the relevant conditions, more quickly to expand the scope of activities, so students will be lost, lost released to the public, the new technology of data and other
18、information published on the web. 5) Mobile SMS platform. Mainly contains the business logic and the short message service of two parts of the program, both use the database to exchange data and information. The business logic can be implemented by Web technology, running on the server, the client o
19、nly needs to access using the Web browser, realize information inquiry, database maintenance, user management, SMS notification and other functions. Short message service program as a background process to provide a unified messaging service, is responsible for the control of GSM module, according t
20、o user requirements for SMS sending and receiving. In addition, in order to provide SMS access service to other platforms, system provides SMS service interface. Development of the SMS service program mainly realizes the following functions: (a) Real-time send text messages, or according to the set
21、time regularly sends text messages. (b) Message effective time setting or number of 6retransmission limit, when the message expires or the retransmission has not yet been sent successfully to send. (c) To send an important message, according to the feedback information confirmation message is receiv
22、ed. (d) Receive real-time messages, providing information inquiry service. (E) Keep sending and receiving a message, for browsing and querying. (f) The GSM module configuration parameters can load or unload GSM module according to need . (g) Other functions, such as the system log, database maintena
23、nce etc. 2 The system implementation technology According to the structure and function of the system, the basic process is shown in figure 2. The user to enter the page can browse related information, through legitimate login, database will according to the different user permissions granted, users
24、 can choose according to the service and the related specific operations. 2.1 The database connection based on JSP Technology JSP is a new Web development tool based on the development of Servlet in SUN. In foreign countries, the EJB+JSP/Servlet+ 7application server and database has become a popular
25、 framework for e-commerce sites. The user through the browser to the server JSP page request, the JSP page to accept the users request, the middle layer application server Servlet server program by Servlet program and the backstage database server interacting, finally generate the client desired Web
26、 page and forwarded to the users browser (Figure 3). It generated Connect by the Java language. Class file package stored in the Web-Inf directory, the code is as follows: The file package written in the Java language and generate Connect. Class stored in the directory, Web-Inf, its code is as follo
27、wsClass. forName(“Oracle.jdbe.driver.OracleDriver”); String url=”jdbc:Oracle:thin:202.201.139.1:1521:chuxing”; String user=”user”; String password=”javachuxing”; Connection conn=DriverManager.getConnection(url, user, password); 2.2 The process of book trade 1) By produced Webpage form by Dreamweaver
28、. The sutdent sell books registration form content including: sell the book 8name, contact information, registration date, title, author, and date of publication, publishing house, new and old, and the number of notes. Buy the book registration form content including: buy the book name, contact info
29、rmation and the books title, author, date of publication, publishing house, new and old, and the number of notes and other information. 2) Using JSP realize data submitted entry (a wizard), and the input data correction. String regesiter1= request.getParameter(dregesiterd) ; String adress1= request.
30、getParameter(dadressd) ; String telephonenumber1=request.getParameter(dtelephonenumberd); String strSQL = dinsert into maishudenji values (“ +bookname1 + “, “ + zuozhe1 + “, “ + banbeng1 + “, “ +chubanshe1 + “, “ + proprice1 + “, “ + price1 + “, “ 9+booknumber1+ “, “+ neworold1+ “, “+ regesiter1+ “,
31、 “+adress1+ “, “+ telepho nenumber1+ “ , “ + email1+ “, “+oicqnumber1+“); RegisterBean.executeUpdate( strSQL ) ; 3) Submit content to display. The database information mapped to corresponding classification Webpage, browse to buy books. 4) Book browsing Webpage access to information, the student fil
32、l out and submit purchase forms for selling books contact. 5) To complete the transaction, delete the old information. maintenance personnel remove registered information by selling books or web site after buyer and seller deal success. 2.3 Design of SMS interface SMS operation interface is the role
33、 of the package to use AT commands to control GSM module through serial port in detail, realize the short message sending, receiving message, delete the message and other functions, provides a simple interface to the message service unit. SERIAL_PORT defines the relevant parameters: including the se
34、rial communication port (portId), (baudRate) the baud rate, parity check mark (parity), data bits, stop bits (dataBit) (stopBit) and so on; structure of SM_PARAM defines the related 10parameters including SMS, short message service center (SCA), mobile phone terminal number (TPA), time stamp (tp_sct
35、s), the content of the message (tp_ud), short message in the GSM module position (nId); CSmsComm is defined in the initialization of serial port (InitComm), close the serial port (CloseComm), send text messages (SendSms), read a message (RecvSms), read more text messages (RecvSmsList), delete one or
36、 more message (DeleteSms) and a serial port (ReadComm), read and write serial (WriteComm) method. Below is the text (SendSms) source code, describes the process of sending a message. 3 Conclusions Campus information service system has changed the traditional information service mode; greatly facilit
37、ate the teachers and students in school. Through 6 months of running, the system is stable, practical and convenient, by parents of students, teachers and students alike.
