Spring Form Tag Library
Spring Form Tag Library The Spring Web MVC framework provides a set of tags in the form of a tag library, which is used to construct views (web pages). The Spring Web MVC integrates Spring's form tag library. Spring's form tag accesses to the command object, and also it refers to the data our Spring controller deals with. A Command object can be defined as a JavaBean that stores user input, usually entered through HTML form is called the Command object. The Spring form tag makes it easier to develop, maintain, and read JSPs. The Spring form tags are used to construct user interface elements such as text and buttons. Spring form tag library has a set of tags such as <form> and <input>. Each form tag provides support for the set of attributes of its corresponding HTML tag counterpart, which allows a developer to develop UI components in JSP or HTML pages. Configuration – spring-form.tld The Spring form tag library comes bundled in spring-webmvc.jar. The spring- form.tld is known as Tag Library Descriptor (tld) file, which is available in a web application and generates HTML tags. The Spring form tag library must be defined at the top of the JSP page. The following directive needs to be added to the top of your JSP pages, in order to use Spring form tags from this library: <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %> Here, form is the tag name prefix, which will be used for the tags from this Spring form tag library in JSP pages. -
B-Prolog User's Manual
B-Prolog User's Manual (Version 8.1) Prolog, Agent, and Constraint Programming Neng-Fa Zhou Afany Software & CUNY & Kyutech Copyright c Afany Software, 1994-2014. Last updated February 23, 2014 Preface Welcome to B-Prolog, a versatile and efficient constraint logic programming (CLP) system. B-Prolog is being brought to you by Afany Software. The birth of CLP is a milestone in the history of programming languages. CLP combines two declarative programming paradigms: logic programming and constraint solving. The declarative nature has proven appealing in numerous ap- plications, including computer-aided design and verification, databases, software engineering, optimization, configuration, graphical user interfaces, and language processing. It greatly enhances the productivity of software development and soft- ware maintainability. In addition, because of the availability of efficient constraint- solving, memory management, and compilation techniques, CLP programs can be more efficient than their counterparts that are written in procedural languages. B-Prolog is a Prolog system with extensions for programming concurrency, constraints, and interactive graphics. The system is based on a significantly refined WAM [1], called TOAM Jr. [19] (a successor of TOAM [16]), which facilitates software emulation. In addition to a TOAM emulator with a garbage collector that is written in C, the system consists of a compiler and an interpreter that are written in Prolog, and a library of built-in predicates that are written in C and in Prolog. B-Prolog does not only accept standard-form Prolog programs, but also accepts matching clauses, in which the determinacy and input/output unifications are explicitly denoted. Matching clauses are compiled into more compact and faster code than standard-form clauses. -
Perl DBI API Reference
H Perl DBI API Reference This appendix describes the Perl DBI application programming interface. The API consists of a set of methods and attributes for communicating with database servers and accessing databases from Perl scripts. The appendix also describes MySQL-specific extensions to DBI provided by DBD::mysql, the MySQL database driver. I assume here a minimum version of DBI 1.50, although most of the material applies to earlier versions as well. DBI 1.50 requires at least Perl 5.6.0 (with 5.6.1 preferred). As of DBI 1.611, the minimum Perl version is 5.8.1. I also assume a minimum version of DBD::mysql 4.00. To determine your versions of DBI and DBD::mysql (assuming that they are installed), run this program: #!/usr/bin/perl # dbi-version.pl - display DBI and DBD::mysql versions use DBI; print "DBI::VERSION: $DBI::VERSION\n"; use DBD::mysql; print "DBD::mysql::VERSION: $DBD::mysql::VERSION\n"; If you need to install the DBI software, see Appendix A , “Software Required to Use This Book.” Some DBI methods and attributes are not discussed here, either because they do not apply to MySQL or because they are experimental methods that may change as they are developed or may even be dropped. Some MySQL-specific DBD methods are not discussed because they are obsolete. For more information about new or obsolete methods, see the DBI or DBD::mysql documentation, available at http://dbi.perl.org or by running the following commands: % perldoc DBI % perldoc DBI::FAQ % perldoc DBD::mysql The examples in this appendix are only brief code fragments. -

Automating Your Sync Testing
APPLICATION NOTE By automating system verification and conformance testing to ITU-T synchronization standards, you’ll save on time and resources, and avoid potential test execution errors. This application note describes how you can use the Paragon-X’s Script Recorder to easily record Tcl, PERL and Python commands that can be integrated into your own test scripts for fast and efficient automated testing.

Assignment 4 Computer Science 235 Due Start of Class, October 4, 2005
Assignment 4 Computer Science 235 Due Start of Class, October 4, 2005 This assignment is intended as an introduction to OCAML programming. As always start early and stop by if you have any questions. Exercise 4.1. Twenty higher-order OCaml functions are listed below. For each function, write down the type that would be automatically reconstructed for it. For example, consider the following OCaml length function: let length xs = match xs with [] -> 0 | (_::xs') = 1 + (length xs') The type of this OCaml function is: 'a list -> int Note: You can check your answers by typing them into the OCaml interpreter. But please write down the answers first before you check them --- otherwise you will not learn anything! let id x = x let compose f g x = (f (g x)) let rec repeated n f = if (n = 0) then id else compose f (repeated (n - 1) f) let uncurry f (a,b) = (f a b) let curry f a b = f(a,b) let churchPair x y f = f x y let rec generate seed next isDone = if (isDone seed) then [] else seed :: (generate (next seed) next isDone) let rec map f xs = match xs with [] -> [] Assignment 4 Page 2 Computer Science 235 | (x::xs') -> (f x) :: (map f xs') let rec filter pred xs = match xs with [] -> [] | (x::xs') -> if (pred x) then x::(filter pred xs') else filter pred xs' let product fs xs = map (fun f -> map (fun x -> (f x)) xs) fs let rec zip pair = match pair with ([], _) -> [] | (_, []) -> [] | (x::xs', y::ys') -> (x,y)::(zip(xs',ys')) let rec unzip xys = match xys with [] -> ([], []) | ((x,y)::xys') -> let (xs,ys) = unzip xys' in (x::xs, y::ys) let rec -
