A presentation that I gave during Oracle Develop 2007

3. Scripting Strikes Back <Insert Picture Here>

7. Java and Scripting Many languages exist Javascript/Rhino Ruby/JRuby Python/Jython JudoScript BeanShell PNuts Tcl/Jacl Groovy Quercus FScript Sleep Bambookit ObjectScript Jickle Yoix Simkin BSF Dawn DynamicJava W4F Netscript PolyJsp FESI iScript

9. Demonstration: Using Javascript in Java 6 <Insert Picture Here>

10. Calling scripts from Java import javax.scripting.* String fLocation = &quot;/OOW-2006-Scripting//customer-validation.js&quot;; ScriptEngineManager manager = new ScriptEngineManager(); ScriptEngine engine = manager.getEngineByName(&quot; JavaScript &quot;); engine.eval(new InputStreamReader( new FileInputStream(fLocation))); inv = ( Invocable ) engine; inv. invoke (&quot;getCustomerDiscount&quot;, new Object[] {customerType} ); Java 6 Build In Feature

11. Easier? <Insert Picture Here>

12. Simple Example Java Code public class FilterApp { public static void main(String[] args) { List<String> list = new ArrayList(); list.add(&quot;Olaf&quot;); list.add(&quot;Tug&quot;); list.add(&quot;John&quot;); list.add(&quot;Dave&quot;); FilterApp filter = new FilterApp(); List<String> data = filter.filterLongerThan(list,4); System.out.println(data.size()); Iterator it = data.iterator(); while (it.hasNext()) {System.out.println(it.next());} } public List filterLongerThan(List list, int length) { List<String> result = new ArrayList(); Iterator it = list.iterator(); while (it.hasNext()) { String item = (String)it.next(); if (item.length()>= length) {result.add(item);} } return result; } }

13. Simple Example Groovy Code def list = [&quot;Olaf&quot;,&quot;Tug&quot;,&quot;John&quot;,&quot;Dave&quot;] def data = list.findAll { it.size() >= 4 } println data.size() data.each { println it } Java 25-30 Lines / Groovy 4 lines
