RM says: my operator is a dummy Operator!!!
Hi,
I have developed my own operator for RM and it works in RM like a charm. Now, I want to call a process which contains my own operator from my java program. But RM says:

As I mentioned previously, my operator MClusterValidator works well in RM. but I am not able to call it from my own java program!!! It has made me so confused. Any Idea please?

Hi Nils,
Thanks for your guide. I have called rapidminer.init(). I changed the ExecutionMode to "EMBEDDED_WITHOUT_UI" and RM find my plugins and works fine. I mean When I change the ExecutionMode to "EMBEDDED_WITH_UI" my plugins are not identified by RM. Do you know what is the difference between these two execution modes and where is the problem?
Thanks again

Is there anyone who can help me solve my problem please?
Hi,
the difference between both modes is that EMBEDDED_WIHTOUT_UI is headless whereas EMBEDDED_WITH_UI is not headless.
It shouldn't change anything regarding plugin loading. So I have to admit I don't know what causes these error but you can have a look yourself at RapidMiner.java line 111.
There ExecutionMode is defined. Furthermore you can try to call Plugin.setInitPlugins(true); before RapidMiner.init()

Thank you Nils.
did you call RapidMiner.init() before executing the process? Plugins need to be initiated before you can use them.
