Add a New Web Application

You can add an application to a run-time production system, such as the iTP

WebServer, in three ways.

•

Deploy an Existing Application WAR File

•

Deploy a Web Application Automatically

•

Create a New Application

Deploy an Existing Application WAR File

If you already have a fully developed application in a WAR file, move the WAR file to

the webapps directory, create the context path in iTP_server.xml, add a filemap in

servlet.config and restart the web container (the NSJSP process).

This action deploys the application. The container creates a directory that uses the

WAR file name (minus the extension) as the context (prefixed by /servlet_jsp/).

For example, if the WAR file name is myapp1.war, the container automatically creates

a directory called myapp1 and appends it to the prefix, creating a dynamic context

called /servlet_jsp/myapp1.

Deploy a Web Application Automatically

NSJSP supports dynamic contexts. Any web application archive (WAR) file that does

not have a corresponding directory of the same name (without the .war extension) will

be automatically expanded, unless the unpackWARs property is set to false. If you

redeploy an updated WAR file, be sure to delete the expanded directory when

restarting NSJSP, so that the updated WAR file will be re-expanded.

Any subdirectory within the application base directory that appears to be an unpacked

web application (that is, it contains a /WEB-INF/web.xml file) will receive an

automatically generated context element, even if this directory does not have context

defined in the iTPWS_INSTALL_DIR/servlet_jsp/conf/iTP_server.xml file.

This generated context entry will be configured according to the properties set in any

<DefaultContext> element nested in its <Host> element. The context path for this

deployed context will be /servlet_jsp/ followed by the directory name. The URL

needs to include the default NSJSP root directory (/servlet_jsp) when accessing a

web application using this automatically generated context:

http://hostname:port/servlet_jsp/web_application_name

To access a servlet from the browser, specify the servlet keyword in the URL, as

shown in the following example:

http://hostname:port/servlet_jsp/web_application_name/servlet

/Myservlet

The net effect of this feature is that you no longer need to define a context for your web

application in iTPWS_INSTALL_DIR/servlet_jsp/conf/iTP_server.xml

and/or a filemap in the servlet.config file, unless you wish to define non-default
