Groovy language in Script activity

[bgoetzmann]

Hello,

The jBPM says a little on how to use another script language in a Script activity.
It seems you have to add something like this, as child element of the script-manager XML element in the jbpm.cfg.cml file:

<script-language name="..." factory="..."/>

for the language you want.

How can I define Groovy? And what interface the class defined in factory attribute is supposed to support?

Thank you,


Bertrand.

Hello,

I would be happy to do some tests, but I don't know what I can use for the "factory" attribute? Any idea?

Thank you,

Bertrand.

After some search, I've found how to proceed. The class to use is org.codehaus.groovy.jsr223.GroovyScriptEngineFactory.

- I added this declaration (in bold) in the jbpm.cfg.xml:

<script-manager default-expression-language="groovy"
default-script-language="groovy">
<script-language name="juel" factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" />
<script-language name="groovy" factory="org.codehaus.groovy.jsr223.GroovyScriptEngineFactory" />
</script-manager>

- You have to have the groovy-all-....jar in your libs

So you use Groovy in a script activity; for example:

<script name="display hello world" lang="groovy"
expr="println 'Salut !'">



But with some test, I see that the lang attribute value is not take in account; and the only way to have Groovy to be executed is to set it as default as I do it above in script-manager XML element.

Is it a bug?


Cheers,

Bertrand.

Could be... I'll have a look in the source tonight to check
