Newbie-friendly Just unzip (untar, install) and go. With the installer I suppose you could have it query where CATALINA_BASE and CATALINA_HOME are to be placed, so the environment variables are constructed and placed in setenv.(bat/sh). If you use the archive rather than the installer, it's up to the user to figure this out. 2. IDE-friendly NetBeans works well with the combined approach. It even uses the standard manager-script role for deployment. Eclipse is not quite as nice, but again using the combined version makes integrating Tomcat with Eclipse as painless as it can be. IntelliJ seems to fit in between NetBeans and Eclipse in terms of Tomcat integration friendliness, and I don't know how it would be impacted by a default separation. Most developers are not very comfortable with administrative tasks (as most administrators are not very comfortable with developer tasks), so placing an additional barrier for developers would not be welcomed by many. 3. Differing install scenarios Finally, I can see a scenario somewhat like the following: a. explode a standard Tomcat distribution b. add a single web application - one per Tomcat c. package the result back up d. write a Chef cookbook for deploying this to 100s of machines For a large environment with clustered applications, this may be the way to go. It's facilitated (somewhat) by the combined approach. . . . just some ramblings /mde/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJUQBdSAAoJEEFGbsYNeTwtqLAIAJvDJxiS1eOHtV1XF1Dfezr1 u+Kom0QeROZ8XEKfcgYvS6Ig72UOFEsREdMvbUv6YfAGP9zZPagb4hvNfAsE4M3Q 9zzpgZovNXl94ZEDi9shcJqJg+oxFVvrzNHPDMryLIou1YmNJdOSbszeC4zgIge2 grYP4xqlMO8VqUTT1eNVbrtoDyEdjGxAJB9BkR+lYPw+tSqFq9u8C2EtRD2lBn7f EA97uE5qYLtoj69sI6ThRc26ox2ZtSiWv0ghwanJP8FhtnT7lLd47A+2GndFbxhx gSRa0z/AHM9x0qI71VyoJfKL41vZGaDZmuPDLU//BF429LfeYzEBOfVSIAmG9R0= =/suK -----END PGP SIGNATURE----- --- This email is free from viruses and malware because avast!
