* 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

TLD (tracking-learning-detection) is a new single-target long time ( Long term tracking ) tracking algorithm. The significant difference between the algorithm and the traditional tracking algorithm is that the traditional tracking algorithm and the traditional detection algorithm can be used to solve the deformation and partial occlusion of the tracked target during the tracking process. At the same time, through an improved on-line learning mechanis
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.

I solved this problem three days ago. Sometimes the inspiration for getting on the toilet suddenly came.
The first time I Parse XML with jstl, I want to print the whole XML file.
What should I do if I don't want to input variables?
Search for answers on the Internet
What to say
Nothing happens. Then, go to stackoverflow.
The problem has not been solved.
When the inspiration came, I went to see its source file.
This is the place for parsing in the jstl package that comes with eclipse.

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...

Because the example in chapter 8 of the Ajax basic tutorial uses jstl1.1, I caught a cold for a few days. Today is the last day, so I have to learn jstl1.1 quickly, even if it is a fur.
