Hi, I am new to Apache Nifi. So I have created a new custom processor by copying the source code of *ListDatabaseTable* processor and build it using maven.
Then I copied nar file to lib folder and restarted it. Then I try to configure the property for Database Connection Pooling Service, so I choose **create new service** option. It throws the following error "*No controller service types found that are applicable for this property"*. Please help me resolving this.
