The URI attribute can also be a non-existent URL, which is a ing of the absolute URL of the library Descriptor (TLD) file to the local system in the web. xml file;3) Example: 5.

The development of a tag library in a JSP requires only the following steps1. Development of custom Label processing classes2, create a *.tld file, each *.tld file corresponding to a tag library, each tag library can contain multiple tags3. Using a custom label in a JSP fileDeveloping Custom Label ClassesWhen a simple tag is used on a JSP page, the underlying is actually supported by the label processing cl

directives in the tag file Tag file and JSP are very similar, there are different, the main difference in directives. JSP's directive has include,taglib and page, but tag has include and taglib, no page, and also provides Tag,tag replaces page in JSP, and provides The Tag directive has the following properties, which are optional: pageencoding : The meaning in the same page that defines the encoding of the tag output. iselignored : The same meaning on the page requires that the EL expressi

OverviewThe builder pattern is a more complex creation pattern that separates the client from the creation of complex objects that contain multiple components (or parts), and the client does not need to know the internal components and assembly methods of complex objects, only the type of builder required. It is concerned with how to create a complex object step by step, different concrete builders define different creation processes, and the concrete

To enable the JSP Container to use the custom behavior in the tag library, the following two conditions must be met:1. Identify the tag representing this custom row from a specified tag Library2.

The first required condition-Identify the tag library that a custom behavior belongs to-is completed by the Taglib Directive's Prefix attribute of the tag command, therefore, all elements with the same prefix on the same page belong to this tag library. Each tag library defines a default prefix, which is used to insert custom tags in the document or page of the tag library. Therefore, you can use prefixes such as jsp, jspx, java, servlet, sun, and sunw (they are all

(Script Injection) the Script insertion attack will save the Script we inserted in the modified remote WEB page, as shown in figure: SQL injection, XPath injection.2. Cross-Site Scripting is temporary and disappears after execution.What types of scripts can be inserted into remote pages? Mainstream scripts include the

Personal Understanding: The construction of a complex object is separated from its representation, allowing the same build process to create different representations. After searching for a number of builder models, I found that some of the builders ' goals were to encapsulate the product in different order, some of the same order of different products, the order was encapsulated in the director, and some were not encapsulated, but deferred to the

There is a mechanism in JSP that allows you to insert a tag similar to HTML in the JSP page. This article introduces the basic concepts and components of JSP custom tag, and how to develop and apply JSP custom tag. What is tagUsing the HTML language, We can edit our webpage as follows: HELLO WORLD HELLO WORLD Here we call In the preceding example, Process of parsing tags on JSP serversAfter a tag is embedded into a JSP page, how does the JSP server parse the tag?

Flexibility is embodied in attribute assignment and can be assigned any value. For example, Encapsulation is embodied in the encapsulation of internal behavior. Because labels are imp

Taglib Tags are defined and distributed in a structure called the tag library. A tag library is a set of metadata and classes:1. Tag Processor: Java class that implements the custom tag function.2. Tag additional information (TEI): provides edge information to JSP containers to confirm tag attributes and create variable classes.3. Tag library Descriptor (TLD): an XML document that describes a single tag and the attributes of the entire tag library. Th

from a specified tag library 2. Find specific classes to implement these custom behaviors The first requirement-find a custom behavior that belongs to that tag library-is done by the prefix of the label directive (Taglib directive ' s Prefix), so elements that use the same prefix on the same page belong to this tag library. Each tag library defines a default prefix that is used in a document in a tag library or in a page to insert a custom label. So, you can use prefixes other than those such
