I had read the article on the website about JSP Custom Tag Library. It's really very good.
But during that I found one error in the sample code.
I request to u check and make it corrected.
The exaple is at the url.

The function in Hello.java
public int doAfterBody(){

}
must have to return integer but in code the return statement is missing.

Thanking you.
