Subject DO NOT REPLY [Bug 49198] There are no binaries for mod_jk for 64bit?

The connection between HTTPD and Tomcat is done via clear text network
protocols. These protocols are not 32Bit/64Bit aware. So you can mix and match
between 32Bit and 64Bit Apache and Tomcat.

Usually you need 64Bit because of more threads per process or because of more
memory needed to handle the load. Since in the combination of Apache and Tomcat
usually the most resource demanding aspect is running on the Tomcat part, you
only need 64Bit processes for Tomcat, but not for Apache.

All common 64Bit operating systems support running a 32Bit binary without

So I suggest you stick to 32Bit Apache but use 64Bit Tomcat.

Concerning 64Bit Tomcat: Tomcat Core is pure Java, so you switch between 32Bit
and 64Bit by simply switching the JVM.

When running as a service on Windows or when including the so-called tcnative
(alias APR connector) on any OS, you will add native code which is different
between 32Bit and 64Bit. So for those parts you will need to retrieve the
correct version.
