Here's my understanding of this: Connectors that integrate Apache and Tomcat have a "side" that "is part of" Apache, and another that "is part of" Tomcat. They can be separated this way because they communicate through a port, and are not otherwise connected (i.e. they are otherwise independent, e.g. in terms of implementation language, they just have to "speak" the same protocol and know what port to communicate through). It's just like you have a separate web browser and web server, and they can use HTTP to communicate on some agreed upon port (usually 80), and it doesn't matter what language they're implemented in. The side that is part of Apache is a module (e.g. mod_jk), and is written in C, as most/all modules are. This is essentially what mod_jk.so is. (I imagine you can have a module written in java, but that it's probably not the best/easiest way to go.) The side that is part of Tomcat is written in Java, as most/all of Tomcat is. This is essentially what tomcat-ajp.jar (on my set up/version, at least) is. > > -----Original Message----- > > From: Remy Maucherat [mailto:[EMAIL PROTECTED]] > > Sent: Monday, September 09, 2002 4:16 PM > > To: Tomcat Users List > > Subject: Re: AJP 1.3 Connector fails to load on Tomcat 4.1.10 > > > > > > Turner, John wrote: > > > So JK (mod_jk) is incompatible with Tomcat 4.1.10?
