Can't find scripting engine for 'groovy'

jcosano — Tue, 18 Jan 2011 10:59:43 GMT

Running under tomcat I have this error:18-ene-2011 11:45:46 org.activiti.engine.impl.interceptor.CommandContext closeGRAVE: Error while closing command contextorg.activiti.engine.ActivitiException: Can't find scripting engine for 'groovy' at org.activiti.engine.impl.scripting.ScriptingEngines

Solved!

I have two problems:

- Two jobs executors running at same time (activiti-rest and activiti-kick)

- I need delete asm-2.2.3.jar from activiti-rest libs (there is asm-3.2.jar)

Tahnks for those findings.

- Two jobs executors running at same time (activiti-rest and activiti-kick)

What was the problem with this? Normally, the job executors should run on multiple machines, going to the same database/

- I need delete asm-2.2.3.jar from activiti-rest libs (there is asm-3.2.jar)

Do you know if the asm-3.2 is from Tomcat itself or is it a dependency of Activiti?

Point 1:
If I have two jobs executors running (kick and rest) then I have an error with:
Timer was updated by another transaction concurrently…
Process has a usertask with timer, after 1 min, go to script groovy that increase a variable +1, send a email and return to user task.
Then, I remember that after solve problem with asm, I obtain same error that timer was updated by another transaction, Then I only put off jobexecutor in kick and this error disappears.

Point 2:
All this libs are under activiti-rest/webinf/lib, and I install activiti 5.1 in a new folder, then, all these libs I suppose that are copied by demo.start
(all two are in setup\files\dependencies\libs)

Problem when I have asm2.2.3 and asm3.2 was with this class

org.objectweb.asm.ClassWritter

Something about init…

And asm3.2 I think is needed for groovy

Ok, that makes sense. Groovy indeed uses asm.

Process has a usertask with timer, after 1 min, go to script groovy that increase a variable +1, send a email and return to user task.
Then, I remember that after solve problem with asm, I obtain same error that timer was updated by another transaction, Then I only put off jobexecutor in kick and this error disappears.

The exception that is thrown can be ignored, since that is the way it works: bot job executors try to lock the same job for executing it. However, one is first and one loses. the one that loses will get the exception, and continue to lock another job. But point taken, maybe the exception shouldnt be displayed in the logs.

Hi,

I had the exact same problem and if anyone else has the same problem I post it here. I had a clean activiti 5.1 with a workflow, consisting only of one script task, written in groovy, writing "blubb" to stdout. When started it replied with

00250000 Wrapped Exception (with status template): org.objectweb.asm.ClassWriter.<init>(I)V I got a NoSuchMethodError and could not figure out the problem. This is the stacktrace:

The solution is to delete asm-2.2.3.jar from activiti-5.1\apps\apache-tomcat-6.0.29\webapps\activiti-rest\WEB-INF\lib. asm-3.2.jar is needed and is already placed there if you ran ant demo.setup before.

Hope this helps anybody, it took me hours to figure this out.

I don't have asm-2.2.3 and I have 2.7 in fact, but I encounted with the same problem~

I don't know what the matter is, any one may help??

and also, I had my tomcat running the demo at the same time, does that matter??

I'm sorry, but I can't see whre in your question you ask for thread-safety.

Hi everyone!

The error: "Can't find scripting engine for 'groovy'" it's clearly.
Can't find groovy language, so: check if your groovy libs are in last stable version, tomcat7 can conflict with old groovy versions, or if your groovy dependency declaration in pom.xml is right. I have solved my problem with a correct dependency declaration in pom.xml:

wrong:


dependency>
   <groupId>org.codehaus.groovy</groupId>
   <artifactId>groovy</artifactId>
   <version>2.0.1</version>
  </dependency>

rigth:


dependency>
   <groupId>org.codehaus.groovy</groupId>
   <artifactId>groovy-all</artifactId>
   <version>2.0.1</version>
  </dependency>

Now, it works fine, before this refactoring, scriptTypes "osama" or "groovy" show same error

My ambient: Activiti 5.10, Tomcat 7.0.22, Groovy 2.0.1

If only I had read this last couple of posts before banging my head against the wall trying to get activiti to notice the groovy scripting engine in version 2.0.x….. I changed my dependencies back to;
<blockcode>
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy</artifactId>
            <version>1.7.5</version>
        </dependency>
</blockcode>
Which worked but its nice to know that to get 2.0.x working the artifactId needs to be <artifactId>groovy-all</artifactId>.

I also verified that it works with the latest version of groovy;

<blockcode>
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-all</artifactId>
            <version>2.1.3</version>
        </dependency>
</blockcode>

Thanks for the post

Yes indeed. The old groovy jar used to contain the scripting engine, but that was changed with the 2.0 version. Now you need to use the -all jar.

I added the note to the docs: https://github.com/Activiti/Activiti/commit/bb96ca6ae22437b0851196abefce88569f13d682
