A proper > installer should: [snip] I would say that if you are installing "your application" onto a customer's computer, it's okay to install support software, as long as it's all in one place. Take the example of an application that requires a particular JRE version or a particular Tomcat version (more likely). If you install everything all at once, but don't interfere with other installs, you should be okay. That means that, for instance, you can't truly "install" the JRE, because that puts all kinds of stuff into the registry, etc. Instead, you'll have to do the equivalent of unzipping the JRE into a subdirectory of your own application, and invoking it directly. This way, you get the version you want (a requirement) and you don't interfere with the customer's operating environment (always a nice thing to avoid). Consider creating an unzipppable-style JRE and Tomcat, and then install everything all at once, preferable into the same directory. For instance: %ProgramFiles%\ReallyCoolApp %ProgramFiles%\ReallyCoolApp\Java %ProgramFiles%\ReallyCoolApp\Tomcat Then, you'll always know that the JRE you want can be invoked like this: %ProgramFiles%\ReallyCoolApp\Java\bin\javaw.exe Or, if you want to use Tomcat's startup scripts (which is probably a good idea), you can do this: set JAVA_HOME=%ProgramFiles%\ReallyCoolApp\Java set TOMCAT_HOME=%ProgramFiles%\ReallyCoolApp\Tomcat %TOMCAT_HOME%\bin\startup.bat Now, Tomcat can use the JRE you wanted to use, but you aren't stomping on any JRE that has been installed by the customer. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGn7g49CaO5/Lv0PARAsAPAJ9L2Qz0hw/KPpGVS20GkdiGgFbeIgCfcMIk IKEVFh7q5EIay042eESuw8A= =J5JT -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
