Apache httpd + mod_jk (or mod_proxy_ajp or mod_proxy_http) + multiple Tomcats should do the trick. Feel free to layer parallel deployment on top of that, though with your requirements and an lb the parallel development doesn't really buy you anything. You should check to see if your webapp is leaky across webapp restarts (with Tomcat continuing to run) because you could bringing-down the JVM if your webapp does not undeploy cleanly /and/ it's got a memory leak. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk3Jgv8ACgkQ9CaO5/Lv0PDfowCeP0R+7tuqM4DL2J1Jo9k+fyzl 3pQAnA2DNg9OsMt0bKeDikcNvs/lwzxj =5CIi -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
