REQUEST

REQUEST这个对象不用事先声明,就可以在JSP网页中使用,在编译为Servlet之后,它会转换为javax.servlet.http.HttpServletREQUEST形态的对象,HttpServletREQUEST对象是有关于客户端所发出的请求的对象,只要是有关于客户端请求的信息,都可以藉由它来取得,例如请求标头、请求方法、请求参数、客户端IP,客户端浏览器等等信息。

    The combinatorial core of the OVSF code assignment problem that arises in UMTS is to assign some nodes of a complete binary tree of height h (the code tree) to n simultaneous connections, such that no two assigned nodes (codes) are on the same root-to-leaf path. Each connection requires a code on a specified level. The code can change over time as long as it is still on the same level. We consider the one-step code assignment problem: Given an assignment, move the minimum number of codes to serve a new REQUEST. Minn and Siu proposed the so-called DCAalgorithm to solve the problem optimally. We show that DCA does not always return an optimal solution, and that the problem is NP-hard. We give an exact nO(h)-time algorithm, and a polynomial time greedy algorithm that achieves approximation ratio Θ(h). Finally, we consider the online code assignment problem for which we derive several results

    Reads/writes text as a character stream, buffering characters so as to provide for the efficient reading/writing of characters, arrays, and lines. The buffer size may be specified, or the default size may be used. The default is large enough for most purposes. In general, each read REQUEST made of a Reader causes a corresponding read REQUEST to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders.

  • This taglib contains tags used to create struts input forms, as well as other tags generally useful

    This taglib contains tags used to create struts input forms, as well as other tags generally useful in the creation of HTML-based user interfaces. Many of the tags in this tag library will throw a JspException at runtime when they are utilized incorrectly (such as when you specify an invalid combination of tag attributes). JSP allows you to declare an "error page" in the <%@ page %> directive. If you wish to process the actual exception that caused the problem, it is passed to the error page as a REQUEST attribute under key org.apache.struts.action.EXCEPTION.

    SCSI Multimedia Commands 鈥?3 (MMC-3) T10/1363-D 5.16 READ CAPACITY Command The READ CAPACITY command (Table 144) provides a means for the Initiator to REQUEST information regarding the capacity of the Logical Unit. This command shall not report the correct capacity of the recorded data for CD-R, CD-RW and DVD-R/-RW media that does not have a Lead-out in the last Session or last Border-out. For CD-ROM, the returned logical block address is modified to allow returning a possibly inexact value (but one with a known error bound) based on the Table of Contents data

    This project developed in java leads us to realize a flight reservation system in order to emulate databases containing the structures for the flight and for the booking. These bases extend the List interface and implements additional search鈥檚 methods. Two interfaces provide an access to this system. The first one reads and handles reservation REQUEST message from a terminal. The arguments are then processed throw a middleware interface that call the flight system methods. The second one, a Graphical User Interfaces (GUI) application using Swing Java Foundation Classes (JFC), offers a simpler access to the systems.

    Imagine that you are a web developer (which is probably not a stretch if you are reading this book) and you are being encouraged to add some Ajax features to a site you’re working on. Maybe the originator of this REQUEST is your boss or your boss’s boss, who is not even sure what Ajax is, let alone what kinds of features might be useful.And maybe you’re not sure yourself. Imagine that your prior experience has mostly been on the server-side, developing in Java or some other server-side technology, and your experience with HTML and JavaScript has been fairly limited.This is the scenario we will explore over the next several chapters as you are introduced to the Dojo Toolkit.

  • A certification path is an ordered list of certificates starting with a certificate issued by the re

    A certification path is an ordered list of certificates starting with a certificate issued by the relying party s trust root, and ending with the target certificate that needs to be validated. Certification path validation procedures are based on the algorithm supplied in ITU-T Recommendation X.509 and further defined in Internet Engineering Task Force (IETF) REQUEST for Comments (RFC) 3280. Certification path processing verifies the binding between the subject distinguished name and/or subject alternative name and the subject public key defined in the target certificate. The binding is limited by constraints, which are specified in the certificates that comprise the path, and inputs that are specified by the relying party. To ensure secure interoperation of PKI-enabled applications, the path validation must be done in accordance with the X.509 and RFC 3280 specifications. This document provides the test assertions and the test cases for testing path validation software against these specifications.
