This code snippet illustrates the creation of an Asset Administration Shell (AAS) with the Java SDK. The BaSys setup for this code snippet is the following:

The BaSys setup consists of a Apache Tomcat server that runs BaSyx Servlets. It contains an Asset Administration Shell provider servlet that exports the created example Asset Administration Shell. The snippet code runs in context of a servlet in the tomcat server and creates, and exports the AAS. It is created as following:

/**
* Example Asset Administration Shell
*/
static class ExampleAssetAdministrationShell extends AssetAdministrationShell {
	/**
	 * Constructor
	 */
	public ExampleAssetAdministrationShell() {
		// Set Asset Administration Shell ID
		setIdShort("aas-001");
	}
}

The AAS sets its short Id meta property to "aas-001". The following code illustrates the deployment of the AAS to the Apache Tomcat server. It maps the path on the HTTP server "/Testsuite/components/BaSys/1.0/SampleAAS/*" to an instance of class AASServlet. This class exports an Asset Administration Shell as HTTP accessible servlet using the BaSys API for Asset Administration Shells.

/**
 * The BaSyx Deployment instantiates and starts context elements for this example. 
 * 
 * This example instantiates the BaSyxExamplesContext_1MemoryAASServer_1SQLDirectory
 * example context that creates one AAS server, and one SQL based AAS registry.
 * 
 * BaSyxDeployment contexts instantiate all components on the IP address of the host. 
 * Therefore, all components use the same IP address. 
 */
public static BaSyxDeployment context = new BaSyxDeployment(
	// Simulated servlets
	// - BaSys topology with one AAS Server and one SQL directory
	TestContext.sqlContext.
		// Deploy example specific servlets to Tomcat server in this context
		addServletMapping("/Components/BaSys/1.0/aasServer/*", new AASServerServlet())
	);

The complete, executable code is available in the basyx.examples project in package <<<>>>.
