jython engine: implementation fails

[Arthur Burma]

Hi,

In order to use python in java project, i've added the jython following dependency :

    <dependency>
			<groupId>org.python</groupId>
			<artifactId>jython</artifactId>
			<version>2.5.0</version>
			<scope>compile</scope>
		</dependency>

But , when i call engine factories :

   


        ClassLoader loader = Thread.currentThread().getContextClassLoader();

        // create a script engine manager
        ScriptEngineManager mgr = new ScriptEngineManager(loader);

        List<ScriptEngineFactory> factories = mgr.getEngineFactories();
        for (ScriptEngineFactory factory : factories) {
            System.out.println("ScriptEngineFactory Info");
            String engName = factory.getEngineName();
            String engVersion = factory.getEngineVersion();
            String langName = factory.getLanguageName();
            String langVersion = factory.getLanguageVersion();
            System.out.printf("\tScript Engine: %s (%s)\n", engName, engVersion);
            List<String> engNames = factory.getNames();
            for (String name : engNames) {
                System.out.printf("\tEngine Alias: %s\n", name);
            }
            System.out.printf("\tLanguage: %s (%s)\n", langName, langVersion);
        }
 

i get the following engines , but not jython ...


ScriptEngineFactory Info
Script Engine: Mozilla Rhino (1.6 release 2)
Engine Alias: js
Engine Alias: rhino
Engine Alias: JavaScript
Engine Alias: javascript
Engine Alias: ECMAScript
Engine Alias: ecmascript
Language: ECMAScript (1.6)
ScriptEngineFactory Info
Script Engine: AppleScriptEngine (1.0)
Engine Alias: AppleScriptEngine
Engine Alias: AppleScript
Engine Alias: OSA
Language: AppleScript (2.0.1)

Are you certain that the Jython scripting engine is in the classpath when you run that code?

Have you tried registering it through the ScriptEngineManager API?

[Arthur Burma]

The classpath is the problem, because when i add jython jar as external dependency , jython engine becomes available.
But then, i use the mvn dependency for jython 2.5.0 (mvn 2.2.1) , ScriptEngine is no avilable anymore...

I had first placed this post in maven forum, but no clue at the moment,

Please do not post the same question to multiple forums: CarefullyChooseOneForum

Let's continue the discussion in this duplicate thread.

It seems as if this has nothing to do with Jython, but is a Maven configuration issue.
