Resolution for HTTP Status 500 error due to missing tag library under Eclipse

Error message:

HTTP Status 500-the Absolute uri:http://java.sun.com/jstl/core_rt cannot be resolved in either web. xml or the JAR files Deployed with this application

Workaround:

Download two jar packages: the Standard.jar package and the Jstl.jar package are copied to the project's/webcontent/web-inf/lib directory.

Tips: These two packages can be downloaded to the Internet, reference http://tomcat.apache.org/taglibs/standard/can be Standard.jar

About Jstl.jar is not limited to the website, there are many

http://archive.apache.org/dist/jakarta/taglibs/standard/binaries/

Jakarta-taglibs-standard-1.1.2.zip 2004-10-25 20:57 933K This URL two packages have ~ hehe!

Quick Method: Open MyEclipse, build a Web project project, in project properties or right-click->build path->libraries tab, select Jstl 1.2.2 Library expand, below there are two jar packages, By widening the dialog box to a later address and locating the directory address, you can copy both packages to the Eclipse project's specified directory, equivalent to the one that eclipse borrowed from MyEclipse.

For example: The directory address I found is:

D:\Myeclipse2016CI4\plugins\com.genuitec.eclipse.j2eedt.core_13.0.0.me201605020208\data\libraryset\

There are many versions of this directory, which I use:

\ JSTL1.2.1 \ lib \ Javax.servlet.jsp.jstl.jar "Jstl package"

\ JSTL1.2.2 \ lib \ Jstl-impl-1.2.2.jar "standard package"

(Novice Summary: In fact, JSTL packet observation suffix is not at the end of Jstl, standard package is to see if it starts with Jstl)

I heard standard package has 4 versions: Impl, Spec, El, compat do not know the difference, but can use, generally with impl
