The JavaServer Pages Standard Tag Library (JSTL) encapsulates, as simple tags, core functionality common to many JSP applications. For example, instead of suggesting that you iterate over lists using a scriptlet or different iteration tags from numerous vendors, JSTL defines a standard tag that works the same everywhere.
You can also download JSTL taglib library from Jakarta apache project online website on http://jakarta.apache.org/builds/jakarta-taglibs/releases/standard/binaries/. Some included jar for JSTL 1.1 library are jaxen-full.jar, jstl.jar, saxpath.jar, standard.jar, xalan.jar. However, only jstl.jar and standard.jar are required.
How to Install JSTL:
1. Download jstl.jar and standard.jar
2. Put those two jar files into /common/lib/ in your Tomcat directory
(All the application under Tomcat will share those jar files inside common/lib/)
3. Below is how your code will looks like if you want to make use of JSTL in your JSP file:
Other taglib that will be used in creating dynamic webpage
We are going to download struts-taglib.jar file. Here is the website where we can find most of the jar files: http://www.java2s.com/Code/Jar/CatalogJar.htm
1. Download the strits-taglib.jar file from that website.
2. Extract the jar file
3. After the jar file has been extracted, you will fid two folders, such as: META-INF and org.
We only care about the META-INF. Open the META-INF and you will find the 'tld' folder.
The files inside the 'tld' folder: struts-bean.tld, struts-html.tld, struts-logic.tld and struts-
nested.tld
Now we will look at the struts-bean.tld.
First, create new folder 'tlib' in your WEB-INF/ directory of your Struts Application. Mine is located here C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\struts2tutorial\WEB-INF\tlib
Copy the struts-bean.tld into tlib folder.
You will need to add struts-taglib.jar file into the /common/lib/ directory of your Tomcat and use your Eclipse - Porject properties to add struts-taglib.jar.
