Hi Domenico, if you wanna install tomcat 1.6 on a 64bit windows server with a 64 bit java you have to download an extra patch for tomcat6w.exe and tomcat6.exe from svn. Afterwards you have to set JAVA_HOME to your JDK (JRE is not enough).

Just think to the pointer addressing , that is based on a 64bit representation of the memory address, rrather than a 32bit. By the way, how did you install it as a service? Did you find a Windows installer? I tryed to execute the 'service.bat install' of Tomcat 6.0.24, but doesn't run. Please could you help me?
