The context.xml File

Before discussing the content of the context.xml file, it is important to understand a

context. A context in NSJSP means a web application. To configure a context within

NSJSP, a Context Descriptor is required. A Context Descriptor is simply an XML file

that contains NSJSP related configuration information for a context. It could include, for

example, naming resources or the session manager configuration. Application specific

context descriptors can be located in

<NSJSP_HOME>/conf/[enginename]/[hostname]/<appname>.xml or

<NSJSP_HOME>/webapps/<appname>/META-INF/context.xml.

This section will be restricted to the default context.xml file located in the

<NSJSP_HOME>/conf directory. The context definition in this file will be loaded by all

web applications in the entire NSJSP Servlet Container. The elements defined by this

context.xml file can be overridden by an application-specific context.xml file. For

example, the <NSJSP_HOME>/conf/context.xml file defines a Manager element. If

the application-specific context.xml file does not define its own manager element

then the one defined in the <NSJSP_HOME>/conf/context.xml file will be used.

Table 3-16 provides an overview of the default context.xml file.

Note. However, parallel deployment where multiple versions of an application exist for a

single context is not supported in NSJSP.
