4.1.2.2: IBM VisualAge for Java
VisualAge for Java Enterprise Edition provides the following tools
for developing Web application components:
-
EJB Development Environment -
Enables you to design and package enterprise beans
as well as database schemas to support persistent features.
- JSP Execution Monitor - Enables you to monitor the execution of JSP source code,
generated servlets, and HTML source code as it is generated. This tool is available
for Windows NT systems.
- Servlet Launcher - Enables you to start a Web server, open your Web browser,
and launch a servlet. This tool is available for AIX and Windows NT systems.
-
WebSphere Test Environment - Enables you to test deployment of
Web application components without a full-fledged
WebSphere Application Server installation.
You can set breakpoints within servlet code,
dynamically update the servlet at breakpoints, and continue running the servlet
with the changes incorporated. These tasks can be performed without restarting
the servlet.

More about the WebSphere Test Environment
IBM VisualAge for Java provides a subset of the WebSphere Application Server
run-time environment in a component called
the WebSphere Test Environment (WTE).
The WebSphere Test Environment offers the following:
- A lightweight run-time environment with no dependency on
WebSphere Application Server availability
- No dependency on an external database unless
entity bean support is required
As a subset of the WebSphere Application Server,
the WTE does not offer certain
features that the application server product does, as follows:
- Secure Socket Layer (SSL) and secure HTTP (HTTPS).
- HTTP-style user ID/password authentication challenge.
- Administrative server and services.
- The XMLConfig tool.
Older XML grammar is used in the WTE configuration.
- Personalization APIs
- Security context and API for enterprise beans.
- Security APIs for servlet sessions, or other security classes
typically involved in sign-on, authentication, or authorization.
- Support for running multiple Web applications
in addition to the default Web application
Tips for using VisualAge for Java
When you are ready to move from the WTE to deployment on the
WebSphere Application Server,
verify that application class paths are properly set in the new environment.
