| <section name="Commons SCXML - Standalone testing, trying out samples"> |
| |
| <p>The SCXML distribution provides utility classes that offer a mock |
| command line environments allowing users to try out samples. The core |
| dependencies for Commons SCXML are Commons Digester (which introduces a |
| transitive dependency on Commons BeanUtils, at the least) and Commons |
| Logging.</p> |
| |
| <p>View the <a href="../dependencies.html">dependencies</a> page for the |
| recommended version numbers. <i>It may be possible to use lower version |
| numbers for the Commons dependencies.</i></p> |
| |
| <p>An environment specific expression language is used in SCXML |
| documents. Commons SCXML currently supports the use of JEXL, Javascript, XPath or Groovy |
| in SCXML documents.</p> |
| |
| <subsection name="Using JEXL in SCXML documents"> |
| |
| <p>The JEXL Standalone class anticipates expressions in JEXL and hence |
| requires commons-jexl.jar.</p> |
| |
| <p>So that amounts to (use the correct local paths and filenames to the |
| <code>jar</code> files and the SCXML document, without the line breaks):</p> |
| |
| <pre> |
| java -classpath |
| |
| commons-logging-1.1.1.jar;commons-scxml2-2.0-SNAPSHOT.jar;commons-jexl-2.1.1.jar |
| |
| <a href="../xref/org/apache/commons/scxml2/test/StandaloneJexlExpressions.html">org.apache.commons.scxml2.test.StandaloneJexlExpressions</a> |
| |
| <a href="https://svn.apache.org/repos/asf/commons/proper/scxml/trunk/src/test/java/org/apache/commons/scxml2/env/jexl/microwave-01.xml">microwave01.xml</a> |
| </pre> |
| |
| </subsection> |
| |
| <p>You could set up something more elegant (a script, an ant task etc.), |
| but that is what it boils down to. |
| If the document is a well-formed SCXML document, you will be able to |
| type ? or help at the console and you can follow the directions thereafter |
| (to simulate events, set variable values, reset the state machine or quit). |
| </p> |
| |
| <p>A few examples are available as part of the |
| <a href="https://svn.apache.org/repos/asf/commons/proper/scxml/trunk/src/test/java/org/apache/commons/scxml2/"> |
| Commons SCXML test suite</a> (look in env.* child packages as well).</p> |
