+
+<P>The Tuscany Java SCA runtime supports implementing SCA components in a wide variety of dynamic or scripting languages by using the &lt;implementation.script&gt; SCDL extension.</P>
+
+<P>Any language that supports the &quot;Scripting for Java&quot; APIs defined by JSR-223 is supported, this includes Groovy, JavaScript, JRuby, Jython, and many others.</P>
+
+<P>To use these languages the SCA assembly SCDL is extended with an &quot;implementation.script&quot; element which has the following options:</P>
+
+
+<DIV class="code"><DIV class="codeContent">
+<PRE class="code-java">&lt;implementation.script [ script=<SPAN class="code-quote">&quot;&quot; | language=&quot;</SPAN>&quot; ] &gt;
+ [inline src]
+&lt;/implementation.script&gt;</PRE>
+</DIV></DIV>
+
+<P>The source code for the script maybe defined in a seperate file pointed to by the 'script=' attribute, or the source code maybe embedded within the SCDL inline inside the &lt;implementation.script&gt; element.</P>
+
+<P>The 'language=' attribute defines the language of the program. The language attribute is optional when the source code is in a separate file in which case the file extension of the file is used to determine the language.</P>
+
+<H4><A name="implementation.script-Someexamples%3A"></A>Some examples:</H4>
+
+
+<P>A Ruby program defined in a file 'myScript.rb' in a folder named 'test':</P>
+
+<DIV class="code"><DIV class="codeContent">
+<PRE class="code-java">&lt;implementation.script script=<SPAN class="code-quote">&quot;test/myScript.rb&quot;</SPAN>/&gt;</PRE>
+</DIV></DIV>
+
+
+<P>A JavaScript program defined inline:</P>
+
+<DIV class="code"><DIV class="codeContent">
+<PRE class="code-java">&lt;implementation.script language=<SPAN class="code-quote">&quot;js&quot;</SPAN>&gt;
+ function sayHello(name) {
+ <SPAN class="code-keyword">return</SPAN> <SPAN class="code-quote">&quot;Hello &quot;</SPAN> + name;
+ }
+&lt;/implementation.script&gt;</PRE>
+</DIV></DIV>
+
+
+<P>When using inline scripts which contain special characters such as XML markup you may need to enclose the source within a CDATA region, for example:</P>
+
+<DIV class="code"><DIV class="codeContent">
+<PRE class="code-java">&lt;implementation.script language=<SPAN class="code-quote">&quot;js&quot;</SPAN>&gt;&lt;![CDATA[
+ function sayHello(inXML) {
+ <SPAN class="code-keyword">return</SPAN> &lt;sayHelloResponse&gt;Hello { inXML..name }&lt;/sayHelloResponse&gt;;
+ }
+]]&gt;&lt;/implementation.script&gt;</PRE>
