Dear Wiki user, You have subscribed to a wiki page or wiki category on "Tomcat Wiki" for change notification.
The "FAQ/Windows" page has been changed by KonstantinKolinko: http://wiki.apache.org/tomcat/FAQ/Windows?action=diff&rev1=17&rev2=18 Comment: Correction: There are not only 2, but 3 different versions of tomcat7.exe. When tomcat7.exe launches a JVM, it can pass to this JVM a number of "command-line options" (things such as "-Xmx", "-Dxxx" and so on). To know which command-line options to pass, it reads specific keys/values in the Windows Registry. And these keys/values are the ones which you can set/modify via the tomcat7w.exe program. - One more thing : because the tomcat7.exe wrapper program actually "runs" the JVM, it must match the type of JVM that it runs, in terms of 32bit/64bit version. If you try to start a 64-bit JVM with a 32-bit tomcat7.exe, it won't work, and vice-versa. This is why there are 2 versions of the tomcat7.exe program, a 32-bit version and a 64-bit version. And you must install and use the correct one matching the JVM that you are using. The Tomcat Service installer for Windows normally does that for you automatically; but if you downloade the ZIP version of Tomcat, you may have to select this by yourself. + One more thing : because the tomcat7.exe wrapper program actually "runs" the JVM, it must match the type of JVM that it runs, in terms of 32bit/64bit version. If you try to start a 64-bit JVM with a 32-bit tomcat7.exe, it won't work, and vice-versa. This is why there are several versions of the tomcat7.exe program: one 32-bit version and two 64-bit version for two different 64-bit CPU architectures. + + One of the 64-bit versions is for the widely used "AMD64"/"x86-64" architecture (x64). If you have a 64-bit processor it is likely that you want to use this one. Another one is for the "Intel Itanium" architecture "IA-64" which is more rare (i64). You must install and use the correct one matching the JVM that you are using. + + The Tomcat Service installer for Windows normally bundles all three versions of the service wrapper and selects one for you automatically, according to the JRE instance that you selected during installation. The ZIP distributives of Tomcat contain only one version of the program, so you have to select the correct distributive to download (*-windows-x86.zip, *-windows-x64.zip or *-windows-i64.zip). ---- [[CategoryFAQ]] --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
