JspWriter out = pageContext.getOut();
out.println("This is my first tag");
}catch(Exception e){e.toString();}
return (SKIP_BODY);
}
publicint doEndTag()
{
return (SKIP_PAGE);
}
}
put it into D:\Program Files\Apache Group\Tomcat 4.1\webapps\custom\WEB-INF\classes\com\pro\StartTag.class
This is my myfirsttag.tld file
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
PUBLIC"-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">
<!-- a tag library descriptor -->
<taglib>
<tlibversion>1.0</tlibversion>

<shortname>custom</shortname>
<uri>/custom</uri>
<tag>
<name>starttag</name>

</tag>
</taglib>
put into D:\Program Files\Apache Group\Tomcat 4.1\webapps\custom\WEB-INF\lib\myfirsttag.tld

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app

</taglib>-->
</web-app>
put into D:\Program Files\Apache Group\Tomcat 4.1\webapps\custom\WEB-INF\web.xml
