public JAXBContext

Returns:

A new instance of a JAXBContext.
createContext(Class<?>[]
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 jakarta.xml.bind module. Can be empty, in which case a JAXBContext that only knows about spec-defined classes will be returned.
classesToBeBound, Map<String, ?>
provider-specific properties. Can be null, which means the same thing as passing in an empty map.

Method Detail

createContextback to summary
public JAXBContext createContext(Class<?>[] classesToBeBound, Map<String, ?> properties) throws JAXBException

Create a new instance of a JAXBContext class.

For semantics see jakarta.xml.bind.JAXBContext#newInstance(Class[], java.util.Map)

Parameters
classesToBeBound:Class<?>[]

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 jakarta.xml.bind module. Can be empty, in which case a JAXBContext that only knows about spec-defined classes will be returned.

properties:Map<String, ?>

provider-specific properties. Can be null, which means the same thing as passing in an empty map.

Returns:JAXBContext

A new instance of a JAXBContext.

Exceptions
JAXBException:
if an error was encountered while creating the JAXBContext, such as (but not limited to):
  1. No Jakarta XML Binding implementation was discovered
  2. Classes use Jakarta XML Binding annotations incorrectly
  3. Classes have colliding annotations (i.e., two classes with the same type name)
  4. The Jakarta XML Binding 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 jakarta.xml.bind module
IllegalArgumentException:
if the parameter contains null (i.e., newInstance(null,someMap);)

createContextback to summary
public JAXBContext createContext(String contextPath, ClassLoader classLoader, Map<String, ?> properties) throws JAXBException

Create a new instance of a JAXBContext class.

For semantics see jakarta.xml.bind.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:String

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 jakarta.xml.bind module.

classLoader:ClassLoader

This class loader will be used to locate the implementation classes.

properties:Map<String, ?>

provider-specific properties. Can be null, which means the same thing as passing in an empty map.

Returns:JAXBContext

a new instance of a JAXBContext

Exceptions
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 jakarta.xml.bind module
