+ <h3><a name="BPELexample-OverviewoftheServiceMix1.xBPELExample"></a>Overview of the ServiceMix 1.x <em>BPEL</em> Example</h3>
+ <p>This document describes how to run ServiceMix's <em>BPEL</em> example and provides details about what it does. For information on the business use case, please refer to: <span class="nobr"><a href="http://www.servicemix.org/Use+Cases" rel="nofollow">Use Case for BPEL</a></span>.</p>
+ <p>The <em>BPEL</em> example illustrates the following:</p>
+ <ul>
+ <li>an example of declarative programming</li>
+ <li>how to perform <em>BPEL</em> integration with ServiceMix</li>
+ <li>how to use <em>JmsTemplate</em> for publishing and subscribing to ActiveMQ topics</li>
+ </ul>
+ <p>The XML code for the <em>BPEL</em> example is located in the ServiceMix installation directory under the <tt>examples\bpel</tt> directory in the <tt>servicemix.xml</tt> file. It is recommended that you refer to the <tt>servicemix.xml</tt> file while reading this document.</p>
+ <p>This example has a client application, <em>JMSClient</em>, which sends a SOAP message to a ServiceMix binding component called <em>myComponent</em>. <em>myComponent</em> forwards the request to the PXE BPEL engine and waits for a response. In other words, <em>JMSClient</em> places a book order and <em>myComponent</em> receives the order and then sends it to the Webservice that takes orders. The client, <em>JMSClient</em>, and the binding component, <em>myComponent</em>, communicate via JMS; this communication is external to the ServiceMix JBI. <em>myComponent</em> and the PXE BPEL service engine communicate internally over the Normalized Message Router (NMR).</p>
+ <h3><a name="BPELexample-PrerequisitestoRuntheBPELExample"></a>Prerequisites to Run the <em>BPEL</em> Example</h3>
+ <p>The following must be installed to run this example:</p>
+ <ul>
+ <li>Java Standard Edition 5.0</li>
+ <li>Ant - <span class="nobr"><a href="http://ant.apache.org" rel="nofollow">http://ant.apache.org</a></span></li>

+ </li>
+ </ul>
+ <h3><a name="BPELexample-RunningtheBPELExample"></a>Running the <em>BPEL</em> Example</h3>
+ <p>Before running this example, the following setup must be done. PXE has a JBI component and deployment unit, which can be auto-deployed in any JBI compliant container, in this case ServiceMix. To use PXE with ServiceMix, the PXE deployment unit must be placed in the <tt>install</tt> directory so it will be auto-deployed in ServiceMix. <b>NOTE:</b> The PXE deployment unit has already been placed into the <tt>install</tt> directory for you - take a look at the <tt>servicemix_install_dir\examples\bpel\install</tt> directory to see the PXE jar file.</p>
+ <p>Perform the following steps to run the <em>BPEL</em> example:</p>
+ <p class="paragraph">
+ <ol>
+ <li>From a command shell, go to the <em>BPEL</em> example directory: <div class="code">
+ <div class="codeContent"><pre class="code-java">cd [servicemix_install_dir]\examples\bpel</pre></div>
+ </div>
+ <p>where <tt>servicemix_install_dir</tt> is the directory in which ServiceMix was installed.</p>
+ </li>
+ <li>Then type: <div class="code">
+ <div class="codeContent"><pre class="code-java">[servicemix_install_dir]\bin\servicemix servicemix.xml
+
+OR
+
+..\..\bin\servicemix servicemix.xml</pre></div>
+ </div>
+ <p>
+ <br clear="all">
+ </p>
+ </li>
+ <li>To trigger the BPEL business process, send it some messages. To do this, compile and run a simple JMS client. The client is built and run from source code using Ant. Execute Ant from the <em>BPEL</em> directory: <tt>servicemix_install_dir\examples\bpel</tt>. To run the JMS client type: <br clear="all">

+ <p>The logical flow of the program is:</p>
+ <p class="paragraph">
+ <ol>
+ <li>The <em>JMSClient</em>, through ActiveMQConnectionFactory, connects to the topic named "demo.org.servicemix.source" and sends a text message containing the <tt>message.soap</tt> file.</li>
+ <li><em>myComponent</em>, being a subscriber of the topic "demo.org.servicemix.source," receives the message.</li>
+ <li>The <em>myComponent</em> implementation class, JmsServiceComponent, sends the message over the ServiceMix bus to the <em>PxeBpelEngine</em> by executing its onMessage() method. The destinationService property defines the destination of the message. <b>NOTE:</b> the destinationService property is found in the <tt>servicemix.xml</tt> file.</li>
+ <li><em>PxeBpelEngine</em> sends a response back to <em>myComponent</em> through the ServiceMix bus, the NMR.</li>
+ <li><em>myComponent</em> uses the <em>jmsTemplate</em> bean to publish the message.</li>
+ <li><em>jmsTemplate</em> uses the <em>jmsFactory</em> bean to get a connection to the port associated with the JMS topic called "demo.org.servicemix.source." The message is published on the "demo.org.servicemix.source" topic.</li>
+ <li><em>JMSClient</em>, being a subscriber of topic "demo.org.servicemix.source," receives the message.</li>

+ <th class="confluenceTh"> Description </th>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>jbi</em></td>
+ <td class="confluenceTd"> jbi is the "id" of the JBI container and provides the basic infrastructure services for <em>myComponent</em>. During initialization, several singletons are instantiated: <em>transactionManager</em>, <em>broker</em>, <em>jmsFactory</em>, and <em>jbi</em>. Also, take note of the properties installationDirPath and deploymentDirPath defined in <tt>servicemix.xml</tt>. ServiceMix automatically installs components found in the folder specified in the installationDirPath property. It automatically deploys component-specific artifacts found in the folder specified in the deploymentDirPath property. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>JMSClient</em></td>
+ <td class="confluenceTd"> This Java standalone program, through the ActiveMQConnectionFactory, connects to topic "demo.org.servicemix.source." It then creates a text message from the file <tt>message.soap</tt> and publishes it to the topic "demo.org.servicemix.source," then requests and waits for a response. It eventually prints the response to the console. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>myComponent</em></td>
+ <td class="confluenceTd"> This JMS service component subscribes to the "demo.org.servicemix.source" topic via its defaultDestinationName property specified in the <tt>servicemix.xml</tt> configuration file. Through its template property, it uses <em>jmsFactory</em> to listen on port 61616 via ActiveMQConnectionFactory. It is implemented by the <em>JmsServiceComponent</em> that has an onMessage() method which is called by ActiveMQ when a message arrives on the topic. This method creates a normalized message, which is sent over the ServiceMix bus to the PxeBpelEngine as specified on its destinationService property. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>jndi</em></td>
+ <td class="confluenceTd"> This bean loads up database and transaction manager resources, which will be used by the other components in the system. More importantly, the JNDI context must be configured so that PXE can be deployed. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>Pxe-install.jar</em></td>
+ <td class="confluenceTd"> This jarfile is located in the <tt>examples\bpel\install</tt> directory. It contains many files, which in turn contain the classes that implement the PXE BPEL engine. It also has a <tt>jbi.xml</tt> file, which is used by ServiceMix to install the PXE BPEL engine as a ServiceMix service-engine component. Note, that in this file the component type is "service-engine" and the component name is <em>PxeBpelEngine</em>. When processes are deployed to the PXE engine (see next row with AsyncProcess-sa.jar), it exposes them as services on the JBI, which can be referenced by other components as destinationService(s), with destinationEnpoint(s) - see the <tt>servicemix.xml</tt> file. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>AsyncProcess-sa.jar</em></td>
+ <td class="confluenceTd"> This jarfile is located in the <tt>examples\bpel\deploy</tt> directory. It contains a <tt>jbi.xml</tt> file, which references the <em>PxeBpelEngine</em>. This ties the processes to the PXE engine described in the previous section. The <tt>jbi.xml</tt> file also references the <tt>AsyncProcess-su.zip</tt> file, which is also contained in the <em>AsycnProcess-sa.jar</em> file. This zipfile contains other configuration files and WSDL files, i.e., <tt>pxe-system.xml</tt> and <tt>resource_X.stream</tt>, which describe the services deployed on the PXE engine. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>broker</em></td>
+ <td class="confluenceTd"> The broker bean uses the <tt>activemq.xml</tt> file to configure the message broker, which handles the JMS messages for the components that require JMS messaging services. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>transactionManager</em></td>
+ <td class="confluenceTd"> This bean is configured to be the default transaction manager for the jbi container. This transaction manager provides transactional services between the resource adapter (in this case the ActiveMQ resource adapter provided by the jencks JCA container) and components in the jbi container. </td>
+ </tr>
+ <tr>
+ <td class="confluenceTd"><em>jmsFactory</em></td>
+ <td class="confluenceTd"> This bean listens on port 61616 and provides a pooled ActiveMQ connection. </td>

+ <h2><a name="BackgroundtoServiceMix-Background"></a>Background</h2>
+ <p>The Enterprise Service Bus (ESB)- which can be defined as middleware that brings together both integration technologies and runtime services to make business services widely available for reuse - offers the best solution for meeting today's enterprise application integration challenges by providing a software infrastructure that enables SOA. However, there are currently a number of different vendors that provide ESB solutions, some of which focus purely on SOAP/HTTP and others who provide multi-protocol capabilities. Because these vendors span the horizon from big enterprise generalists (app servers), to mid-tier enterprise integration providers, all the way to smaller, ESB/integration specific-providers; there doesn't seem to be an established consensus regarding the key requirements for an ESB.</p>
+ <p>As application architects, we have often thought about what requirements would define an ESB designed specifically to cater to the needs of an agile, enterprise integration model. In building for these specific requirements, we realized that we actually needed to develop a new type of ESB, hence the ServiceMix project.</p>
+ <h2><a name="BackgroundtoServiceMix-CharacteristicsofanAgileESB"></a>Characteristics of an Agile ESB</h2>
+ <p>The main criteria we were looking for in our ESB are as follows:</p>
+ <h3><a name="BackgroundtoServiceMix-Standardsbased"></a>Standards based</h3>
+ <p>While standards-based support is marketed by many ESB vendors, the support is provided externally, requiring developers to work with proprietary APIs when directly interacting with internal APIs. ServiceMix was designed with the requirement to eliminate product API lock-in, by being built from the ground up to support the Java Business Integration specification (JSR 208). Our agile ESB needs to use JBI as a first class citizen, but also support POJO deployment for ease of use and testing.</p>
+ <h3><a name="BackgroundtoServiceMix-Flexible"></a>Flexible</h3>
+ <p>Another characteristic of an agile ESB is the flexibility with which it can be deployed within enterprise application integration framework: standalone, embedded in an application component, or as part of the services supported by an application server. This allows for component re-use throughout the enterprise. For example, the binding for a real-time data feed might be aggregated as a web-service running within an application server, or streamed directly into a fat client on a traders desk. An agile ESB should be able to run both types of configurations seamlessly.</p>
+ <p>To provide rapid prototyping, an agile ESB should support both scripting languages and embedded rule engines, allowing business processes to be modeled and deployed quickly.</p>
+ <h3><a name="BackgroundtoServiceMix-Reliable"></a>Reliable</h3>
+ <p>Our ESB needs to handle network outages and system failures and to be able to reroute message flows and requests to circumvent failures.</p>
+ <h3><a name="BackgroundtoServiceMix-BreadthofConnectivity"></a>Breadth of Connectivity</h3>
+ <p>An agile ESB must support both two way reliable Web-services and Message Oriented-Middleware and needs to co-operate seamlessly with EIS and custom components, such as batch files.</p>
+ <h2><a name="BackgroundtoServiceMix-Conclusion"></a>Conclusion</h2>
+ <p>We also wanted our agile ESB to be vendor independent and open source, to promote user control of source code and direction. An added benefit of this is not only the zero purchase cost, but the total cost of ownership will be reduced where users are actively contributing and maintaining our ESB.</p>
+ <p>We rapidly came to the conclusion, that as there was no single product that would adequately meet our needs, we would have to just go a head and build one!</p>
