RE: SOLR 3.3 DIH and Java 1.6

[Dyer, James]

Taking a quick look at the code, it seems this exception could have been thrown 
for four reasons:  
(see org.apache.solr.handler.dataimport.ScriptTransformer#initEngine)

1. Your JRE doesn't have class "javax.script.ScriptEngineManager"  (pre 1.6, 
loaded here via reflection)

2. Your JRE doesn't have any installed scripting engines.  This little program 
outputs 1 engine on my JRE with 6 aliases:
        [js, rhino, JavaScript, javascript, ECMAScript, ecmascript]
-----
import javax.script.ScriptEngineFactory;
import javax.script.ScriptEngineManager;

public class TestScripting
{
        public static void main(String args[])
        {
                ScriptEngineManager sem = new ScriptEngineManager();
                for(ScriptEngineFactory sef : sem.getEngineFactories())
                {
                        System.out.println(sef.getNames());
                }
        }
}
-----
3. You specified an unsupported scripting engine name in the "language" 
parameter (see http://wiki.apache.org/solr/DataImportHandler#ScriptTransformer)

4. The script you wrote in the <script> tag has errors.

Unfortunately, it looks like all 4 of these things are being checked in the 
same try/catch block.  So you could have any of these problems and are getting 
a potentially misleading error message.

One way to eliminate all #1&#2 is to run the test 
"org.apache.solr.handler.dataimport.TestScriptTransformer" on your JRE and see 
if it passes.  (see here for how:  
http://wiki.apache.org/solr/HowToContribute#Unit_Tests)

Thanks Mikhail and Juampa. How can I prove to our Systems guys that the Rhino
Engine is not installed? This is the only way that I can prove that it's not
installed and we have to have it for SOLR data importhandler script to run.

Thanks again.
