JServ Overview
JServ Overview
Apache JServ is made up of an Apache module called mod_jserv, which runs in the
httpd process, and a servlet engine, which runs in a Java process. mod_jserv, which
is implemented in C, functions as a dispatcher, routing each servlet request to a
JServ process for execution.
The servlet engine runs in its own JVM and is solely responsible for parsing the
request and generating a response. As
Figure 5–1
shows, multiple JServs can service
requests. The HTTP server process and the JServ process communicate using the
Apache JServ Protocol 1.2.
