Currently, We have 2 flowable engines running and sync through DB.

1. flowable-ui for the modeler
2. Spring boot app Custome Rest API Setup  
Now we have created a spring boot app For Tasklistner Delegate implementation which we have added as a jar at “ **flowable-ui\WEB-INF\lib** ” .

Now while starting up Flowbale UI is throwing **a class not found error**.

_ **Unable to read meta-data for class com.delegates.ServiceConfig** _

_**Caused by: java.io.FileNotFoundException: class path resource [com/delegates/ServiceConfig.class] cannot be opened because it does not exist**_

It’s not able to initiate my delegate class I guess I’m missing something on Autoconfig’s side while creating beans.

```
@Bean
public ProcessEngineConfigurationConfigurer configurationConfigurer() {
    return new ProcessEngineConfigurationConfigurer() {
        public void configure(SpringProcessEngineConfiguration processEngineConfiguration) {
            processEngineConfiguration.addConfigurator(new FormEngineConfigurator());
        }
    };
}

```

}

**File TaskCompleteListener.java**

package com.delegates;  
import org.flowable.engine.delegate.TaskListener;  
import org.flowable.task.service.delegate.DelegateTask;  
import org.springframework.stereotype.Component;  
`@Component`(“taskCompleteListener”)  
public class TaskCompleteListener implements TaskListener {  
public void notify(DelegateTask delegateTask) {  
System.out.println(“Complete”);  
}  
}

`# Auto Configuration Import Filters`  
org.springframework.boot.autoconfigure.EnableAutoConfiguration=  
com.delegates.ServiceConfig

Hey @psychicDivine,

Are you sure that the `ServiceConfig` class is part of the jar you have added?

It feels like it isn’t.

Cheers,
