Hi,
At last, I have found the appropriate place for tag libraries. Here is a
"Hello" tag which I have tried. What I found useful with this approach is
that it doesn't need to create a jar file for the tags for development
purposes. Moreover while creating a .war file it's much easier to pack the
entire directory and we need not do anything extra.
If there is any other method which is more simpler or easier to maintain for
both development as well as packaging, please do let me know.
Step 1
--
Place all your tag handler source files in a package under WEB-INF\classes
directory. For example, I have used the following,
$ORION\\web\WEB-INF\classes\tagext\Hello.java
***
package tagext ;
import java.io.* ;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class Hello extends TagSupport {
public int doStartTag() throws JspException {
return EVAL_BODY_INCLUDE ;
}
public int doEndTag() throws JspException {
try {
pageContext.getOut().write( "Hello" ) ;
} catch ( IOException e ) {
throw new JspTagException( "JSP IOException" ) ;
}
return EVAL_PAGE ;
}
}
Step 2
--
Define TLD under WEB-INF\tlds directory. For example,
$ORION\\web\WEB-INF\tlds\taglib.tld

Step 3

Referring a tag from JSP file. Example.
<%@ taglib uri="WEB-INF/tlds/taglib.tld" prefix="learn" %>
