Teiid embedded samples WebService
Teiid Embedded is a light-weight version of Teiid, it contain an easy-to-use JDBC Driver and an embed Query Engine. The Embedded mode supply almost all Teiid features without JEE Container involved, it supply a convenient way for Users who want integrate Teiid with their Application.
This document show how Teiid Embedded use Web Service as data source, the architecture as below:
JVM
JBoss EAP 6.3 hold the StateService.jar run on JVM, it supply State WebService for users to extract all states information, or extract only one state information via stateCode(for example, state code CA will get California information).
Note that: In this example, JBoss EAP 6.3 run on localhost. Web Service StateService Example have detailed steps for deploy
StateService.jarand StateService.
StateServiceVDB
A Virtual Database (VDB) is an artifact that defines the logical schema model combining one or more physical data sources to provide easy data integration. In this example, StateService VDB has Model StateService point to Web Service run on JBoss Server.

JVM
Java Application run on JVM, load the StateServiceVDB and invoke Web Service via JDBC. The mainly Code Snippets:
init("translator-ws", new WSExecutionFactory());
WSManagedConnectionFactory managedconnectionFactory = new WSManagedConnectionFactory();
server.addConnectionFactory("java:/StateServiceWebSvcSource", managedconnectionFactory.createConnectionFactory());
start(false);
server.deployVDB(new FileInputStream(new File("vdb/webservice-vdb.xml")));
conn = server.getDriver().connect("jdbc:teiid:StateServiceVDB", null);
