1 Getting Started

Developing an Application

1 If the co mponent is not already i nstalled on t h e machin e where you want to

develop your application, unpack and install the component as follows:

a. Copy the package that was created in the last step in “Creating a Java

Component” on page 1-5.

b. If the package is a self-extracting executable, paste the package in a

directory on the development machine, and run it. If the package is a

.zip file, unzip and extract the contents to the development machine.

Note You must repeat these steps for each development machine where

you want to use the components.

The first step is not necessa ry if you are developing your app li cati on on the

same machine where you created the Java component.

2 If you have not already done so, set the environment variables that are

required on a d ev elo pm ent machine. See “Settings for Environment

Variables (Development M achine)” on page 6-2.

3 Import the MAT

LAB libraries and the component classes into your code

with the Java

import functio n. For example:

import com.mathworks.toolbox.javabuilder.*;

import componentname.classname; or import componentname.*;

4 Use the new fu

nction in your Java code to create an instance of each class

you want to us

e in the application.

5 Call the class methods a s you would do with any Java class.

6 Handle data conversion as needed.

When you invoke a method on a Java Builder compone nt, the input

parameters received by the method must be in the MATLAB internal array

format. You can either (manually) convert them y ourself within the calling

program, or pass the parameters as Java data types.
