If you compare content of *-windows-<arch>.zip files, you should note that only two files differ between each of them: tomcat7.exe - service runner tcnative-1.dll - Tomcat-Native (optional component, can be deleted) They are loaded in the same process as JVM and thus have to use the same CPU architecture. Service configuration application (tomcat7w.exe) is 32-bit. The rest of code is neutral to CPU architecture. > or is the installer solely 64bit for installing onto 64bit OS? and the > tomcat just uses which ever java you have installed to create its jvm? On a 64-bit system you can install either 32-bit version or 64-bit one -- use the same as the version of Java that you installed. Recent versions of Tomcat (more recent that ~6 months ago -- see change log for details! ) have all three versions of (tomcat7.exe tcnative-1.dll) packed within installer and will autoselect the one that matches the JRE. You select the JRE during installation. > > i have been asked to change a set of servers from 32bit to 64bit for tomcat > and java > if it turns out that the java is the only thing i need ot change it will > save me tons of work > if the tomcat needs to be installed that nots a biggy as i can copy and > paste the tomcat folder into the place of the existing and put back the conf > and webapps folder so in theory this will allow me to work as if nothing > changed.... > > you answers on the 32-64bit is greatly appreciated!! > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
