How to acess controller service from advanced UI

New Contributor

with the custom processor i have, i need to get controllerService inside advanced UI, with following code im not able to access it, getting following casting error. also im not sure why its returning "com.sun.proxy.$Proxy78" class.

am i doing it right ? how can i get controller service under advance UI ?

MYDBCPConnectionPool cs = (MYDBCPConnectionPool) nifiWebContext.getControllerService(componentDetails.getProperties().get("MYDBCP-connection-pool"), processorId);
logger.info(cs.getClass().getName());
>> com.sun.proxy.$Proxy78 cannot be cast to org.apache.nifi.dbcp.MYDBCPConnectionPool

also what is the dependency requirement for "advanced-UI" when i need to access "ControllerService" . didn't find any source or example.

ok. found the issue.

added "<scope>provided</scope>" to maven dependencies of "MYProcessor" project.

before "Myservice" was deployed twice one inside "MYProcessor.Nar" and one alone "Myservice.nar" which was wrong. adding following code to MYProcessor project solved it.

<scope>provided</scope>
