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 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)

Subject: RE: SOLR 3.3 DIH and Java 1.6
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.
