<h1>Tuscany RDB DAS exposed as an SCA service</h1>
|
|
|
|
|
|
<h3>Introduction</h3>
|
|
|
|
<p>This is a sample SCA service that exposes DAS functionality.</p>
|
|
<p>This service would allow you to utilize DAS in a language neutral fashion, consuming existent or adHoc commands.</p>
|
|
|
|
|
|
<h3>Consuming the DAS service</h3>
|
|
|
|
|
|
<p>You should add the dependency on your client project pom file</p>
|
|
|
|
|
|
<p>
|
|
<div class="codebox2">
|
|
<pre>
|
|
<!-- DAS Service -->
|
|
<dependency>
|
|
<groupId>org.apache.tuscany.das.samples</groupId>
|
|
<artifactId>sample-das-service</artifactId>
|
|
<version>${pom.version}</version>
|
|
</dependency>
|
|
</pre>
|
|
</div>
|
|
</p>
|
|
|
|
<br>
|
|
<p>In order to consume the service, you would have to create a SCDL that references it, see sample below:</p>
|
|
|
|
<p>
|
|
<div class="codebox2">
|
|
<pre>
|
|
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0" name="DASServiceComposite">
|
|
<component name="DASServiceComponent">
|
|
<implementation.composite name="DASServiceComposite" jarLocation="lib/sample-das-service-1.0-incubator-SNAPSHOT.jar"/>
|
|
</component>
|
|
</composite>
|
|
</pre>
|
|
</div>
|
|
</p>
|
|
|
|
|
|
<h3>Sample Architecture</h3>
|
|
|
|
<p>This service utilizes the following Interface as its definition:</p>
|
|
|
|
|
|
<p>
|
|
<div class="codebox2">
|
|
<pre>
|
|
|
|
public interface DASService {
|
|
|
|
public void configureService(InputStream configStream) throws DASServiceException;
|
|
|
|
public DataObject executeCommand(String commandName, Vector commandArguments) throws DASServiceException;
|
|
|
|
public DataObject execute(String adHocQuery, Vector commandArguments) throws DASServiceException;
|
|
|
|
public void applyChanges(DataObject graphRoot) throws DASServiceException;
|
|
|
|
}
|
|
</pre>
|
|
</div>
|
|
