Schnittstelle BeanDataSourceManager

public interface BeanDataSourceManager
To provide a bean datasource for i-net Clear Reports this interface needs to be implemented inside a servlet environment. The declared methods will be used by i-net Clear Reports to check which Java Beans can be provided by the bean datasource and also query the data of the java beans. To setup a bean datasource in a servlet environment you will have to follow these steps:
  • write an implementation of this class and add it to the classpath of your servlet environment
  • define a datasource for i-net Clear Reports with the following properties
