Creating a Java Component

To create a component you need to write M-code (or use existing code) and

then create a project in MATLAB Builder for Java that encapsulates the code.

In general, the steps are as follows:

1 Write,test,andsavetheMATLABcodetobeusedasthebasisforthe

Java component.

2 Set the environ

ment variables that are required on a d ev elopment machine.

See “Settings f

or Environment Variables (Development Machine)” on page

6-2.

3 W hile you are still in MATLAB, issue the following command to open the

Deployment Tool:

deploytool

4 Use the Deployment Tool to create a project that contains one or more

classes.

a. Create the project by clicking the New Project icon

in the t oolbar.

b. Specify the project name and location.

to be created. You can change the default.

c. Add class names for classes that you want to create as part of the

Java package.

d. Add one or more M-files that you want to encapsulate in each class.

e. Add helper files as needed to support the classes.

f. Save the project.

5 Build the package.

The b uild process for a project copies a Jav a wrapper class in the

\src

subdirectory of your project directory. It also copies a .jar file and .ctf

file in the \distrib subdirectory of your project directory. The files in the

\distrib directory define your Java component.
