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 sudde

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

Sometimes when writing a front-end JSP page, you need to get background data, or you want to handle some logic in the background. You can use this method:

1. Create a new tag named name. TLD. Note that this file should be placed under the WEB-INF file (same as Web. XML) and will be automatically loaded at runtime
2. Now we start to implement the getname method of the tag. Create a new package com. yuqiaotech. PMS. webapp. tags, which contains two files: getname. Java and pmstag. java.
Getname. Java

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.
I read some articles on the Internet and got a rough idea. To use jstl1.1 at least, the jstl. jar and standard. Jar classes are required, and the next C. TLD can be used.

Alternatively, you can use the GIT tool to clone the file in Linux:
# Git clone git@github.com: alantrrs/opentld. Git
(2) My compiling environment is Ubuntu 12.04 + opencv2.3
Install opencv 2.3:

Just a few simple words, just ask your friends to exchange research.
Parallelism is not an improvement of algorithms, but a pursuit of real-time running.
A brief example is provided:
In the C ++ source code of the TLD algorithm:
