Hi

There are two ways to do this

1) Yes, you can run as the system user if you get hold of the AuthenticationComponent. You need to keep the current user and restore the current user in a finally block.

2) Use a non-service bean (which will not have security checks)
This will maintain auditing etc against the current user.
For example there are two node service beans "nodeService" and "NodeService". The first is the internal bean, the second is the public service: the first bean wrapped with security and transactional proxies.

I would suggest selected use of the second approach.

This is some great information and it's helping me a bit, but I'm a little confused as to how to configure my system to pick up the non-proxied nodeService. I am writing a Java-backed action that needs to run as the system user. I don't know where to specify the different nodeService in the configuration files.

On the other hand – I'd like to explore using the AuthenticationComponent as a solution, but I don't know how to get a reference to that from within an action.

Any thoughts?
