The following sections provide an overview of administration and configuration tasks for using JSP tag extensions:
The following steps describe how to configure a JSP tag library. You can also package a tag library as a jar
file (see
Packaging a JSP Tag Library as JAR File).

web.xml
. For example:<taglib>
<taglib-uri>myTLD</taglib-uri>
<taglib-location>WEB-INF/library.tld</taglib-location>
</taglib>
In this example the tag library descriptor is a file called library.tld
. Always specify the location of the tld
relative to the root of the Web application.
WEB-INF
directory of the Web application. In your JSP, reference the tag library with a JSP directive. For example:
<%@ taglib uri="myTLD" prefix="mytaglib" %>
WEB-INF/classes
directory of your Web application.
In addition to the procedure described in the previous section Configuring JSP Tag Libraries, you can also package a JSP tag library as a jar
file:
taglib.tld
.For more information, see Creating a Tag Library Descriptor.
META-INF
.taglib.tld
file you created in step 1 into the META-INF
directory you created in step 3jar
file by executing the following command from the directory you created in step 2jar cv0f myTagLibrary.jar
(where myTagLibrary.jar
is a name you provide)
jar
file into the WEB-INF/lib
directory of the Web application that uses your tag library.web.xml.
For example:<taglib>
<taglib-uri>myjar.tld</taglib-uri>
<taglib-location>
/WEB-INF/lib/myTagLibrary.jar
</taglib-location>
</taglib>
<%@ taglib uri="myjar.tld" prefix="wl" %>
