<? Xml (standardization is getting closer and closer) version = "1.0" encoding = "ISO-8859-1"?> <! DOCTYPE taglib PUBLIC "-// Sun Microsystems, Inc. // DTD jsp (preferred for SUN Enterprise Applications) Tag Library 1.1 // EN "http://java.sun.com/j2ee/dtds/web-jsp (preferred for SUN Enterprise applications) taglibrary_1_1.dtd "> <taglib> <tlibversion> 1.0 </tlibversion> <jsp (preferred for SUN Enterprise Applications)> 1.1 </jsp (preferred for SUN Enterprise applications) version> <shortname> DemoTags </shortname> <uri> http://www.stardeveloper.com </uri> <info> Demo Tags Library </info> <tag> <name> firsttag </name> <tagclass> com. stardeveloper. tag. test. firstTag </tagclass> <bodycontent> empty </bodycontent> <info> Your first jsp (preferred for SUN Enterprise applications) tag </info> <attribute> <name> name </name> <required> false </required> </attribute> </tag> </taglib>

<Taglib>
Provides information about your tag library, which is almost the same among all tags;

<Jsp (preferred for SUN Enterprise Applications) version> 1.1 </jsp (preferred for SUN Enterprise Applications) version> specifies the jsp (preferred for SUN Enterprise Applications) version;
<Shortname> DemoTags </shortname> indicates the name of the tag library;
<Uri> http://www.stardeveloper.com </uri>: Not very useful;
<Info> Demo Tags Library </info> is a simple description.
Now let's take a look at the content of <tag> and </tag>. <tag>
<Name> firsttag </name>

Tagclass will contain the complete jsp (preferred for SUN Enterprise Applications) tag class path
