![]() ![]() The method to extract class from row on the domain object is not accessible. The static nested class can be accessed just like the other static members of the enclosing class without having an instance of the outer class. Reflection is a feature in the Java programming language. ![]() Cause: EclipseLink is unable to extract data row, because EclipseLink cannot access the row specified in the databaseRow argument of the method. Internal exception, mapping and descriptor appear only if EclipseLink has enough information about the source of the problem to provide this information.įormat EXCEPTION : Exception nameĭescriptor Exception EXCEPTION : .DescriptorExceptionĮXCEPTION DESCRIPTION: The reference class is not specified.ĮCLIPSELINK-00001: The attribute, with parameter (DatabaseRow), is not accessible. We have already discussed inner classes in the previous tutorial. In Java, nested classes are of two types: Nested non-static class (Inner class) Nested static class. Such classes are known as nested classes. If a mapping within the descriptor caused the error, then the name and parameters of the mapping are part of the returned message, as this exampledemonstrates. As learned in previous tutorials, we can have a class inside another class in Java. The message that is returned includes the name of the descriptor or mapping that caused the exception. A description of the problem, taken from the raised exceptionĭescriptorException is a development exception that is raised when insufficient information is provided to the descriptor.The exception number in the format of EXCEPTION.Each exception code corresponds to an exception class and includes the following information: This section lists EclipseLink exceptions and provides numerical ranges of their error codes. 17 Entity Manager Setup Exceptions (28001 – 28007).14 XML Marshal Exceptions (25001 – 25020) It has access to members of the enclosing class (outer class).12 Remote Command Manager Exceptions (22101 - 22111).This variable is initialized from an extra argument passed to the inner class constructor. That is the way, an inner class is linked to the enclosing class. The Java compiler automatically adds an extra private instance variable of the outer class to the inner class. 10 EIS Exceptions (17007 – 17025), 90000, 91000 In Java, an inner class is defined relative to the outer class instance. ![]()
