Borland web container implementation
Typical web application development process
In a typical development phase for a web application:
1 The web designer writes the JSP components, and the software developer creates
the servlets for handling presentation logic.
2 In conjunction, other software engineers write Java source code for servlets and the
.jsp and .html for processing client request to the server-side components (EJB
application tier, CORBA object, JDBC object).
3 The Java class files, .jsp files, and the .html files are bundled with a deployment
descriptor as a Web ARchive (WAR) file.
4 The WAR file (or web module) is deployed in the Borland web container as a web
application.
For more information about using the BES Deployment Descriptor Editor (DDE) to
create a Web ARchive (WAR) file, go to the User's Guide, Using the Deployment
Descriptor Editor section.
Web application archive (WAR) file
In order for the Borland web container to deploy a web application, the web application
must be packaged into a Web ARchive (WAR) file. This is achieved by using the
standard Java Archive tool jar command.
The WAR file includes the WEB-INF directory. This directory contains files that relate to
the web application. Unlike the document root directory of the web application, the files
in the WEB-INF directory do not have direct interaction with the client. The WEB-INF
directory contains the following:
Directory/File name
/WEB-INF/web.xml
/WEB-INF/web-borland.xml
/WEB-INF/classes/*
/WEB-INF/lib/*.jar
Contents
the deployment descriptor
the deployment descriptor with “Borland-specific DTD.”
the servlets and utility classes. The application class loader
loads any class in this directory.
the Java ARchive (JAR) files which contain servlets, beans, and
other utility classes useful to the web application. All JAR files
are used by the web application class loader to load classes
from.
Borland-specific DTD
The web.xml file contains the standard deployment descriptor facilities for web
applications. However, the web-borland.xml file contains some Borland-specific
extensions. The following tables describes the Borland-specific elements and how to
use them. Some of these augment the standard constructs and some are new
constructs.
