Hi,
What kind of JDK are you using?
Here are the links[1][2][3] of groovy unit test.

many thanks for your help. I thought groovy engine was in the camel
packages.

Hi,

Did you put the groovy-all jar and the groovy-engine jar into your classpath?I didn't find any unit test error about in the camel-groovy andcamel-script module.


Here are the maven dependency

         <dependency>
             <groupId>com.sun.script</groupId>
             <artifactId>groovy-engine</artifactId>
             <version>20080611</version>
         </dependency>

         <dependency>
             <groupId>org.codehaus.groovy</groupId>
             <artifactId>groovy-all</artifactId>
             <version>1.7.0</version>
         </dependency>

the same issue is seen on 2.1.0 as well. With the dependencycamel.script ver 2.1.0 added, a route with groovy filter fails

to instantiate with the error

  java.lang.IllegalArgumentException: No script engine could be created
for:
groovy

Env: JDK 1.6,Camel 2.1.0

do I need to include any other jars for jsr223 groovy support.

Has anyone run into similar problems and have a solution? I've worked
with
camel-juel and got it's dependencies configured properly. Groovy
should
have been just as simple but I must be missing something (i've
reviewed
POMs for camel-groovy and camel-scripting). Any pointers would be much
appreciated.

BTW this stack trace is generated when a route is activated. Here is a
snippet of the routebuilder code that uses groovy:

                when(groovy("in.headers.JMSType { h ->
h.startsWith('foobar')}")).
                    to("log:fooCategoryName?level=DEBUG")
