Create a Component

Install SmartTools on your Eclipse

Please install SmartTools Feature on your Eclipse if it is not already done.

Create a project

Launch the "New SmartTools Component" wizard.

New Component Wizard

Type your component name and click Finish. It is used for the package path, so you may put mycompany.mymodule.mycomponent for example.


The wizard build the basic structure of the component: a CDML for describing the services of your component, a Facade for your business code and an Activator for OSGi.

new Project

Build the component

SmartTools generates a Ant script called "buildST.xml", which will generate the container of your component, and link it to your facade.

Delete buildST.xml to force it to re-generate

Delete buildST.xml

Add the buildST.xml Ant script to the Ant view and execute it.

Add buildST.xml and execute it

No error should be in the console

Console result

Refresh the project.

Refresh the project

Java will compile the generates classes, and no Error should remain on the Java project. Build of all Java files

Execute the builtST.xml everytime you change the CDML file. The wizard puts 1 input and 1 output you can duplicate as you want.

the CDML

Create new services

Let's create two new services, generate again the component, and complete the Facade

Duplicate the "input" and "output" entries to new entries, say for example "input2" and "output2".

Change the type of the parameters of these services

new CDML

After you saved the CDML, you have to generate the component again with buildST.xml.

Add buildST.xml and execute it

Remember to refresh the project.

Refresh the project

Now Errors come from the generated Facade, which needs the input2 method from your own Facade.

Eclipse helps you in resolving this issue quickly.

Create method input2 in the facade



The outputs are optional, and if you want to invoke an output from your facade, you need to duplicate the method from the generated facade to your facade, and put it as an abstract method.



It should be completed now.
