The NOVLLIBAJC-JS is in the Library and is added to the ecmascript configuration on the driver.

Tried deleting and redeploying the entire driver with no success, same error

The namespace prefix and URI are present: es & http://www.novell.com/nxsl/ecmascript --- java extension is unchecked.

thanks,
