[SOLVED?] Unknown operator class: 'process'!.

veve

Hello,

On Friday everythong worked fine. Today: i'm finding myself with this error:

"Process cannot be created: com.rapidminer.tools.XMLException: Unknown operator class: 'process'!."

I'm having this error only when I try to run a process on the server.
The server is up and running.

I tried:
- restarting the server
- restarting the RapidAnalytics server
- removing and adding again the RapidAnalytics repository
- re - install rapidminer

On the server I have the following error:

2014-09-29 09:26:42,797 SEVERE [de.rapidanalytics.web.tools.ProcessServiceDelegate] (http-8088-6) Cannot create process: com.rapidminer.tools.XMLException: Unknown operator class: 'process'!: com.rapidminer.tools.XMLException: Unknown operator class: 'process'!

Any ideeas?

Thank you!

Worked when I reinstalled the server in another place

However:

- I think that this is not a real solution
- I do not understand how come if I installed the server in another place, it still has my process scheduler history (?)

Thank you!

Hi Alina,

did you receive this error with all of your processes? Usually this type of error only occurs when certain processes made with a RapidMiner version 4.6 or older are deployed to the server.

Cheers,

Hello,

yes! even for a newly empty process!
I never used RapidMiner 4.6. I used only RapidMiner 5.3

The error just camed back again (I did nothing special!)
I tried installing again RapidAnalytics on the server but this time it didn't worked...

Where shoud I change and what in order to make it work again?

Thank you!

I saw that on the folder

RapidMiner-Server-CE-Installer-1.3.015/server/default/data/wsdl/RapidMiner-Server-CE-1.3.015.ear/RapidAnalytics_Service_War.war/

I have a file called ProcessService.wsdl and one ProcessService_1_3.wsdl

is this ok?

Thank you!

Also, I saw that on the Operators and Extension section from RapidAnalytics  there is none operator right now (it wasn't like this before)...

Ans, I saw this logs at starting

Hi Alina,

it looks like no operators are loaded during startup. Can you send me your server config files?
