Your Role in the WebFigure Deployment Process

Depending on your role in your organization, as well as a number of other criteria, you may need to implement either the beginning or the advanced configuration of WebFigures.

The table WebFigures for MATLAB Builder JA Deployment Roles, Responsibilities, and Tasks describes some of the different roles, or jobs, that MATLAB Builder JA users typically perform and which method of configuration they would most likely use when implementing WebFigures for MATLAB Builder JA.

WebFigures for MATLAB Builder JA Deployment Roles, Responsibilities, and Tasks

Role	Typical Responsibilities	Tasks
MATLAB programmer	Understand end-user business requirements and the mathematical models needed to support them. Write MATLAB code. Build an executable component with MATLAB tools (usually with support from a Java developer). Package the component for distribution to end users.	Write and deploy MATLAB code, such as that in Assumptions About the Examples. Use Quick Start: Implementing a Custom WebFigure to easily create a graphic, such as a MATLAB figure, that the end user can manipulate over the Web.
Java developer (business-service developer or front-end developer)	Design and configure the IT environment, architecture, or infrastructure. Install deployable applications along with the proper version of the MCR. Create mechanisms for exposing application functionality to the end user.	Use Quick Start: Implementing a Custom WebFigure to easily create a graphic, such as a MATLAB figure, that the end user can manipulate over the Web. Use Advanced Configuration of a WebFigure to create a flexible, scalable implementation that can meet a number of varied architectural requirements.

What You Need to Know to Implement WebFigures

The following knowledge is assumed when you implement WebFigures for MATLAB Builder JA:

• If you are a MATLAB programmer:

  • Advanced to expert knowledge of MATLAB

• If you are a Java developer:

  • Knowledge of how to create a J2EE Web site on a J2EE-compliant Web server

  • Experience deploying MATLAB applications is helpful

Required Products

Install the following products to implement WebFigures for MATLAB Builder JA, depending on your role.

MATLAB Programmer

• MATLAB

• MATLAB Builder JA

• MATLAB Compiler

• MATLAB Compiler Runtime (see the system requirements at http://www.mathworks.com/
  support/sysreq/current_release/)

Java Developer

• Java Developer's Kit (JDK) (see the list of supported compilers).

• J2EE compliant Web server, such as Apache^® Tomcat™

• Java Runtime Environment (JRE) (see the system requirements).

  Note   At this time, only J2EE Web servers that use the Sun JVM support WebFigures.

Assumptions About the Examples

MATLAB Programmer

Role	Knowledge Base	Responsibilities
MATLAB programmer	MATLAB expert No IT experience No access to IT systems	Develops models; implements in MATLAB Uses tools to create a component that is used by the Java developer

To work with the examples in this chapter:

• Assume the following MATLAB function has been created:

  function df = getKnot()
          f = figure('Visible','off'); %Create a figure.
                                  %Make sure it isn't visible.
          knot;                   %Put something into figure.
          df = webfigure(f);      %Give figure to function
                                  % and return the result.
          close(f);               %Close the figure.
  end

• Assume that the function getKnot has been deployed in a Java component (using Getting Started for example) with a namespace of MyComponent.MyComponentclass.

• Assume the MATLAB Compiler Runtime (MCR) has been installed. If not, refer to Installing the MATLAB Compiler Runtime (MCR) in the MATLAB Compiler documentation.

Set DISPLAY on UNIX Systems

If you are running a UNIX variant, such as Linux, WebFigures requires a display to be available in the Web server's environment in order for text labels to be rendered properly.

Set the DISPLAY environment variable to a valid X Server before running the WebFigure application.
