Yup: something like <form action="ResponseDemoServlet"> in your HTML and then a <servlet> that defines the servlet in web.xml and then a <servlet-mapping> which maps it later on -- also in web.xml. > You are likely going to be confused throughout this book if all > the examples are based on Tomcat 4.

I completely agree: while webapps are (mostly) forward-compatible with newer servers, a lot of old books are going to be relying on features like the invoker servlet. Go get a copy of "Tomcat: The Definitive Guide" by Jason Brittain (who happens to lurk on this list, FYI) and Ian Darwin. It's targeted at Tomcat 6.x but not much has changed (with old features) since its publication. There's plenty of new, exciting stuff but the basics will be well-covered by T:TDG. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEAREIAAYFAlFIxO4ACgkQ9CaO5/Lv0PAN4gCfWm/TCacnneTXW6i0377mABPu cSoAoK53HOPGBQZQ/Vdac9Ey2pJLnJE0 =NNvB -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
