+
+<p>
+The Tuscany Java SCA runtime has a script container allowing SCA components to
be implemented with a variety of scripting languages.
+</p>
+<p>
+To use the script container you use the <implementation.script> element
in the component SCDL. The <implementation.script> element has two
attributes, 'script' and 'class'. The 'script' attribute is required and
defines the location of the script program. The 'class' attribute is optional
and enables specifying the class or prototype to be used if the script language
supports such concepts.
+</p>
+<p>
+The language the script is implemented in is defined by the suffix of the
script attribute value. For example, the '.js' suffix indicates a JavaScript
program, or '.py' indicates a Python program. The script container uses the <a
href='http://jakarta.apache.org/bsf/' target='_blank'>Apache BSF script
engine</a>, so any script language supported by BSF can be used as an SCA
component implementation.
+</p>
+
+<p>
+</p>
+
+<p>
+</p>
+
+<p>
+</p>
+
+<p>
+</p>
+
+<p>
+The following example shows the files necessary to implement a simple
HelloWorld style SCA component using the script container and a JavaScript
program.
+</p>
+
+<p>
+The composite SCDL:
+</p>
+<p>
+<table width="100%" class="ex" cellspacing="0" bgcolor="#f4f4f4">
+<tr><td>
+<pre>
+<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
+ name="HelloWorldComposite">
+
+ <component name="HelloWorldComponent">
+ <implementation.script script="HelloWorld.js"/>
+ </component>
+
+</composite>
+</pre>
+</td></tr>
+</table>
+</p>
+
+<p>
+and the associated JavaScript program, 'HelloWorld.js':
+</p>
+<p>
+<table width="100%" class="ex" cellspacing="0" bgcolor="#f4f4f4">
+<tr><td>
+<pre>
+function sayHello(s) {
+ return "Hello " + s;
+}
+</pre>
+</td></tr>
+</table>
+</p>
+
+<p>
+This next example shows a HelloWorld program using the Ruby language, and the
use of the <implementation.script> element 'class' attribute to
specifying the class of the component implementation:
+</p>
+<p>
+The composite SCDL:
+</p>
+<p>
+<table width="100%" class="ex" cellspacing="0" bgcolor="#f4f4f4">
+<tr><td>
+<pre>
+<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
+ name="HelloWorldComposite">
+
+ <component name="HelloWorldComponent">
+ <implementation.script script="HelloWorld.rb"
class="Helloworld"/>
+ </component>
+
+</composite>
+</pre>
+</td></tr>
+</table>
+</p>
+
+<p>
+and the associated Ruby program, 'HelloWorld.rb':
+</p>
+<p>
+<table width="100%" class="ex" cellspacing="0" bgcolor="#f4f4f4">
+<tr><td>
+<pre>
+class Helloworld
+
+ def sayHello(s)
+ return "Hello to " + s + " from the Ruby World!"
+ end
+
+end
