Invoking a Servlet With a URL
You can call a servlet deployed to the Communications Server by using
a URL in a browser or embedded as a link in an HTML or JSP file. The
format of a servlet invocation URL is as follows:
http://server:port/context-root/servlet-mapping?name=value
The following table describes each URL section.
Table 8–1 URL Fields
for Servlets Within an Application
|
URL element
|
Description
|
|
server:port
|
The IP address (or host name) and optional port number.
To access the default web or converged
web/SIP module for a virtual server, specify only this URL section.
You do not need to specify the context-root or servlet-name unless you also wish to specify name-value
parameters.
|
|
context-root
|
For an application, the context root is defined in the context-root element
of the application.xml, sun-application.xml,
or sun-web.xml file. For an individually deployed
web or converged web/SIP module, the context root
is specified during deployment.
For both applications and individually deployed web or
converged web/SIP modules, the default context root is the name
of the WAR or SAR file minus the .war or .sar suffix.
|
|
servlet-mapping
|
The servlet-mapping as configured in the web.xml or sip.xml file.
|
|
?name=value...
|
Optional request parameters.
|
In this example, localhost is the host name, MortPages is the context root, and calcMortgage is
the servlet mapping:
http://localhost:8080/MortPages/calcMortgage?rate=8.0&per=360&bal=180000
When invoking a servlet from within a JSP file, you can use
a relative path. For example:
<jsp:forward page="TestServlet"/>
<jsp:include page="TestServlet"/>
