The operator class 'legacy:write_model' is unknown for versiion 71
I'm with my first steps in embedding RapidMiner to my JavaApplication.
My first process uses the "Model Write" operator, but this one seems deprecated as one can see in this XML line:
<operator activated="true" class="legacy:write_model" compatibility="7.0.001" expanded="true" height="68" name="Write Model" width="90" x="849" y="187">
The problem is that my application cannot find the operator class:
INFO: <em class="error">The operator class 'legacy:write_model' is unknown. Possibly you must install a plugin for operators of group 'legacy'.</em>
I've created a FAT jar with all dependencies, so rapidminer-extension-legacy-7.0.1-all.jar is also on the classpath.
What do I have to do in the code so that the plugin classloaders can find this operator?
PS: If "Model Write" operator is deprecated, what is the new alternative way of saving a model?
