Child Elements Nested in the Service Element
Following are the child elements nested in the Service Element:

Connector Element

Engine Element

Executor Element
Connector Element
The Connector element connects the HTTPD component of the iTP Secure
WebServer with the Servlet Server Class or Manager Server Class. The connector
receives all NSJSP request messages on the $RECEIVE file. Each process can
have only one $RECEIVE file and since the NSJSP connector receives messages
through this file, there can be only one Connector element that reads messages
from $RECEIVE. The connector handles messages based on the type of the
message. If the message is from an HTTPD component, an HTTPD message is
handed over to a component that handles the message from HTTPD. In NSJSP,
the message is handed over to the NSJSPHttp11Processor component to
process the message. If it is a JMX message, the message is handed over to the
component that handles JMX messages, which is
NSJSPMessageConnectionHandler.
To understand the properties that affect the connector behavior, it is important to
understand the major differences between the NSJSP connector and the default
connector supplied with Apache Tomcat.
The Apache Tomcat connector receives inputs through a TCP/IP port in the form of
a stream of characters. The connector is responsible for all the HTTP1.1 protocol
validation and translation. In this way, the connector functions as a simple web
server.
