Scott, I'm sorry for the delay on this. If you are using a 64-bit JVM, the JVM can't load a 32-bit native library as it is mandatory that the bits of both binaries match. In case you are using the community edition of the wrapper, we would be happy to provide you with a Trial license in order to test your application running on a 64 bit JVM with the Standard/Professional Edition of the Wrapper. http://wrapper.tanukisoftware.com/doc/english/requestTrial.jsp If you already have a license please try to replace the 32-bit binaries of the wrapper (wrapper.exe & wrapper.dll) with the 64-bit binaries. Another option would be to use a 32 bit JVM. In order to do so, you need to set the property "wrapper.java.command" to point to a valid 32-bit Java executable. http://wrapper.tanukisoftware.com/doc/english/prop-java-command.html Cheers, Christian On Sat, Jan 15, 2011 at 3:01 AM, Scott Vandezande <van...@gm...> wrote: > Yes I'm using a 64 bit JVM - java.exe is the executable. > > > > On Jan 13, 2011, at 5:41 PM, Christian Mueller <chr...@ta...> wrote: > >> Scott, >> >> When a user logs off windows send a signal to all running processes so >> they can respond accordingly. >> The wrapper catched the logoff signal and thus running as service >> ignoring this signal.
