I am trying to run the last example from chapter 9 and i am receiving the error

org.apache.jasper.JasperException: The absolute uri: http://jakarta.apache.org/taglibs/mailer-1.0 cannot be resolved in either web.xml or the jar files deployed with this application


I typed in the above url"http://jakarta.apache.org/taglibs/mailer-1.0" and i receive the error page cannot be found".

I downloaded the file taglibs-mailer.jar
and saved it to taglibs-mailer.tldlib
and saved the file
taglibs-mailer.tld to taglibs-mailer.tld
 But when i type in the information in the file premailer.html and click submit i receive the above error message.
Can you please advise.


My classapths are set up to pick up JavaMail1.2 and the Java Beans Framework

Can you please advise

I think there is a mistake in the book for this exercise.

For the web.xml file, the <taglib-uri> is set to:
"http://jakarta.apache.org/taglibs/mailer"

Whereas in the corresponding jsp page which references the uri, in the taglib declaration the value is set to:
"http://jakarta.apache.org/taglibs/mailer-1.0"

these values need to be the same basically, and they are not.



I am having trouble with this chapter also.

I get the following exception when I run the example in the browser:

javax.servlet.ServletException: javax/mail/Authenticator
    org.apache.jasper.servlet.JspServlet.service(JspSe rvlet.java:244)
    javax.servlet.http.HttpServlet.service(HttpServlet .java:802)

help would be very much appreciated.
