Access uploaded file in Groovy Script

[jvaidya]

I'm trying to Base64 encode a file that a user uploads in an Activiti form, and then save the resulting encoding as a string to be accessed by other parts of the business process. I thought a Groovy Script in a Script task would be the best way to do this. How do I access the file in the script? 

Would something like: 

execution.getVariable('file'); 

give me access to the raw file? 

Thanks!

Thanks so much that's really helpful! Unfortunately, I'm getting this error: 

problem evaluating script: javax.script.ScriptException: groovy.lang.MissingPropertyException: No such property: relatedContentService for class: Script1

Any thoughts?

No idea, I built this just now in my 1.6.1 environment and it runs ok (Process Services 1.6.1 on Tomcat).

Managed to solve this issue! We had to change the activiti-app.properties configuration file to set:

# Beans whitelisting
beans.whitelisting.enabled=false

# EL whitelisting
el.whitelisting.enabled=false

Ahh yes, Alfresco in their infinite wisdom decided to lock down security by disabling access to beans without telling anyone in 1.6.

Should have thought of that.
