32-bit service on 64-bit windows?
Can I install a 32-bit jvm and create a tc 5.5.28 service on win 2008 64-bit server? Or do I need a 64-bit jvm to do that? Or do I need TC 6.0.x? If I need tc6, which jvm is needed? Or will either work? My app doesn't stretch the memory limits of the 32-bit, let alone needing 64-bit memory space. Thanks!

The mode of the service wrapper must match the mode of the JVM to be used, not the mode of the OS. Note that the 5.5.28 .exe installer incorrectly checks the mode of the OS rather than the JVM, so it will install the wrong service wrapper for your situation. The easiest way around this is to use the .zip download, which includes the 32-bit service wrapper. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

If I need tc6, which jvm is needed? Or will either work? My app doesn't stretch the memory limits of the 32-bit, let alone needing 64-bit memory space. I belive that this has been discussed, extensively, under various guises on this forum. So you may want to search the archives. But, since it is not, to my knowledge, clearly expressed on the Tomcat website, let me try a summary : - 32-bit .exe programs seem not to run under 64-bit Windows, and vice-versa 64-bit .exe programs not to run under 32-bit Windows. - the Java JVM is at least in part a .exe program, so it will have to be a version matching the plaform bit-ness - the JVM is not included in Tomcat downloads, so that's a bit you'll have to find out elsewhere, and install by yourself. - Tomcat itself on the other hand is a Java application, which should run unchanged under a 32-bit or 64-bit JVM, so there is only one Tomcat - but, under Windows and to run it (the JVM which will run Tomcat) as a Windows Service, one additional piece is needed, the (in)famous tomcatX.exe, which is a .exe wrapper around the JVM, making it behave like a Windows Service is supposed to. (This tomcatX.exe (where X is the tomcat major version), is in fact always the same program, just renamed for version's sake.) Being an .exe program, it also thus needs to have the appropriate bit-ness for the platform at hand. - when you install Tomcat 6 on a Windows system, from the downloadable exe or windows service installer version, I believe that we are told that it does the right thing, installing the appropriate 32-bit or 64-bit tomcatX.exe, as appropriate to the platform. (We are however told this by word of mouth on this list, because the fact is not mentioned on the Tomcat download page). - when you download and install the .zip version however - planning to configure it yourself as a service later using supplied .bat files - then for some reason not both the 32-bit and 64-bit versions of the wrapper are included, and only the 32-bit version is. Which leaves the hapless would-be 64-bit installer (person) in a bind, because it is not clear where on the Tomcat website one finds the 64-bit version. Not on the download page, that's certain. (although that information has been provided many times in this list's archives, and might even be buried in a FAQ). It is also rather distressing, and puzzling, that when one downloads and installs the .exe version, one does not receive all the same files which are included in the .zip version. This fact alone has caused these list archives to be much more voluminous than they would otherwise be. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

It depends on the .exe, but in my experience, most user applications will work. Ones that try to run as a service may be an exception; this is the first time I've tried to install a service on x64.

It looks loike in addition I have an attention problem, because I missed Chuck's first phrase above. Apart from that, I know that I have a Tomcat 5.5 running as a Windows service somewhere under a 64-bit Windows XP. But I thought I remembered needing for that a 64-bit JVM, and I also needed a 64-bit tomcatX.exe, but which bitness I associated with the platform, not with the JVM. But now I am a bit confused again, because it seems that the bitness of the tomcatX.exe has not to do with the platform, but everything to do with the chosen JVM, which could be a 32-bit version even on a 64-bit platform. So is this tomcatX.exe then always a 32-bit application ? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Yes, you've always been able to run 32-bit programs on x86-64 versions of Windows. (The older and deservedly maligned IA64 versions of Windows were not so compatible.) But I thought I remembered needing for that a 64-bit JVM, and I also needed a 64-bit tomcatX.exe, but which bitness I associated with the platform, not with the JVM. Nope, 32-bit JVMs work fine on 64-bit Windows. it seems that the bitness of the tomcatX.exe has not to do with the platform, but everything to do with the chosen JVM, which could be a 32-bit version even on a 64-bit platform. Which is what I said in the first response. So is this tomcatX.exe then always a 32-bit application ? No, there are 32- and 64-bit versions of tomcatX.exe available; you must choose the one that matches the mode of the JVM you intend to use. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
