So a vendor came to you -- unsolicited -- and asked if they could deploy your webapp to the cloud and instead of saying "you figure it out", you decided to instead spend your own resources to "come to a quick solution"? Talk about the wail wagging the dog... I'm shocked that the cloud provider didn't simply suggest that you deploy thousands of separate webapps. That would certainly run-up the cost and make them very happy. Honestly, if the webapp wasn't built with multi-tenancy in mind, there's no magic you can add to it from the outside in order to make it multi-tenant friendly. You can play tricks with ClassLoaders to minimize memory usage, but you'd better be careful that there aren't static caches or other nasty surprises that will cause the walls to come crumbling down. - -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/ iQIcBAEBCAAGBQJRba0pAAoJEBzwKT+lPKRY/vEQAJwb1A4rc7Y5Au9zK7RLRiB9 yiBogKO2/gOHlpSaBVm3wmzpo2/D8fqlGkooWMl2WctshzEJSt8Q40TSkn28vfhw 3FZDIIoVFThqBwi1fcipKxRiGEmiyfvfo9o2uO7XtGhoE0dcdhSykmLHWrRCcI5Q Od6QCoC3Nn/sblvGSQsWQ64WQvinvZJr3mNbSqt8K6i6pK9ysf/nwGEmLCx4PWxh 1s9Z8qKKGlJLsD4l8OG4UHvlFJ51iMITK+23rpj+SmmUKGFRlsdivkPhtK67634D xe+2UWD0t/nvVRh0QUFrv3r3d3oSzg1/LtVtKcdjEHG79FcN15ZGxWUR7e4WXIhe cMSbkqYk3I1+emKJyl4AWABclEfriO7AQEYHapnRjdZ65Vz2aPJdY5Jr/BJ7WZIh Zkl9M2XHRvVCJQHmtqvYEH6iun4vIcZXt6Euby0dwfNdvTb+Z5p2eNFN/wi8D/1o qwLQ8LGpsGffuwatriB9rxA69YJ+6FdN6LLmcGG2Qjb1K3Fgp3wBWceqQ89yfblI z8iNXfLxnRoGqm2H72q6wozQgkbMpdSD37o6Q8dQ5+6WiHDSdI680k3EsgFxzm6Y q4ZLmne2S3zJxjLUGHPK/Fa8sfg8szhHIQQGqm7JcESc5J4MKgVBMwXBignnOvgz YNsIauMPh8LRZdZytS3g =2EuS -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
