The whole tag library project is available for dowloading, as tar.gz or as a zip file, here .

General INSTALL information:

This tag library is designed to be used in JSP pages compliant with the JSP 2.0 specification.

To get this tag library working you will have to copy the jar files

Jar file Download Description

util-taglib.jar download The tag library jar file.

to the WEB-INF/lib/ directory on your web application.

NOTE: We advise you to use the versions of additional jar files comming with the tag library and not to download them directly from other of our related projects. By doing so, you may create imcompatibilities: though we will do our best to make sure a tag library is using the latest version of a jar file.

You will also need to copy the tld file util-taglib.tld to somewhere in the WEB-INF/ directory, for instance to WEB-INF/ itselft, and add to the web.xml file, in the part corresponding to the tag libraries, the following lines:
<taglib>
    <taglib-uri>URI identifying your tag lib</taglib-uri>

    <taglib-location>/WEB-INF/util-taglib.tld</taglib-location>
</taglib>
                            
For more information on how to modify the web.xml file peruse the documentation coming with your WEB server/container. For information on how to use tag extensions on your own JSP pages consult the JSP 2.0 specification.

Description	Returns the substring (from the body) after the start attribute and before the end attribute. The body is evaluated.

Attributes:
Name	Required	Dynamic	Description
end	false	true	The ending substring. If missing the end is assumed.
start	false	true	The starting substring. If missing the beginnig is assumed.

Examples:

3-doonlyonce (tag).
Description	This tag executes its body only once. You may have several doonlyonce tags in a page they are identified by the var attribute (a variable is created and placed in the scope to know the tag has already been executed once).

The attribute scope determines the extend of the uniqueness of the doonlyonce tag (once per page, once per request, once per session or once per application.
