1. Label Encapsulation of Java code implemented in a manner similar to HTML tags . First: The technical standard for developing labels--- custom labels is formed. Second: the Java Standard tag library (a collection of a series of tags developed by sun itself)Jstl, and the expression language EL. 2. Custom Labels (1) Understanding:you can allow users to develop their own label specifications according to the

* Bloggers have also done several or large or small web background projects, where the database is necessary to have a dictionary table to store a number of commonly used business dictionaries, page rendering can also be a variety of tags and expressions. When we query the data, the primary table usually stores the primary key of the dictionary table, The corresponding dictionary is then obtained through a table query. Now I want to share a "different way" and talk about learning together idea
This is a helloworld program. Problems solved: 1. The project cannot be processed using EL expressions; 2. How should TLD be defined; 3. Custom a JSP tag 1. The El expression cannot be used.

After searching online for a long time, I finally found an Eclipse plug-in htmleditor for formatting JSP HTML. I think formatting is barely done However, the custom TLD tag cannot be parsed. It took me a long time to figure out the reason for this plug-in... When my JSP uses htmleditor (amateras) by default to open the JSP page When the tag of the TLD

TLD is the abbreviation of taglib descriptionThe last piece in the custom label puzzle is the TLD (Tag library descriptor) file. Each tag you create must be declared in a TLD file, and this file must be deployed along with the Java processor class for the tag. As seen in the previous section, the servlet container know

SummaryThis paper studies the long-term tracking problem of unknown target in video stream. In the first frame, the tracking target is defined by the selected location and size. In each of the following frames, the tracking task is to determine the location and size of the target or to indicate that the target does not exist. We propose a novel tracking framework (TLD) that explicitly decomposes long-term tracking tasks into tracking, learning, and de
Analysis of TLD Visual Tracking Technology In the monitoring of urban rail transit, the intelligent video analysis technology once experienced great challenges. However, due to the complicated monitoring environment of urban rail transit, it not only has a large area, long perimeter, multiple platforms, multiple entrances and exits, numerous fences, and other related equipment. This complex environment brings many difficulties to Intelligent Analysis.
