    • Method Detail

      • createContext

        JAXBContext createContext​(Class<?>[] classesToBeBound,
                          Map<String,?> properties)
                   throws JAXBException

        Create a new instance of a JAXBContext class.

        For semantics see JAXBContext.newInstance(Class[], java.util.Map)

        Parameters:
        classesToBeBound - List of java classes to be recognized by the new JAXBContext. Classes in classesToBeBound that are in named modules must be in a package that is open to at least the java.xml.bind module. Can be empty, in which case a JAXBContext that only knows about spec-defined classes will be returned.
        properties - provider-specific properties. Can be null, which means the same thing as passing in an empty map.
        Returns:
        A new instance of a JAXBContext.
        Throws:
        JAXBException - if an error was encountered while creating the JAXBContext, such as (but not limited to):
        1. No JAXB implementation was discovered
        2. Classes use JAXB annotations incorrectly
        3. Classes have colliding annotations (i.e., two classes with the same type name)
        4. The JAXB implementation was unable to locate provider-specific out-of-band information (such as additional files generated at the development time.)
        5. classesToBeBound are not open to java.xml.bind module
        IllegalArgumentException - if the parameter contains null (i.e., newInstance(null,someMap);)

      • createContext

        JAXBContext createContext​(String contextPath,
                          ClassLoader classLoader,
                          Map<String,?> properties)
                   throws JAXBException

        Create a new instance of a JAXBContext class.

        For semantics see JAXBContext.newInstance(String, ClassLoader, java.util.Map)

        The interpretation of properties is up to implementations. Implementations must throw JAXBException if it finds properties that it doesn't understand.

        Parameters:
        contextPath - List of java package names that contain schema derived classes. Classes in classesToBeBound that are in named modules must be in a package that is open to at least the java.xml.bind module.
        classLoader - This class loader will be used to locate the implementation classes.
        properties - provider-specific properties. Can be null, which means the same thing as passing in an empty map.
        Returns:
        a new instance of a JAXBContext
        Throws:
        JAXBException - if an error was encountered while creating the JAXBContext such as
        1. failure to locate either ObjectFactory.class or jaxb.index in the packages
        2. an ambiguity among global elements contained in the contextPath
        3. failure to locate a value for the context factory provider property
        4. mixing schema derived packages from different providers on the same contextPath
        5. packages are not open to java.xml.bind module
