The JCR implementation supports various methods of the node type registration.

Run time registration from .xml file

ExtendedNodeTypeManager nodeTypeManager = (ExtendedNodeTypeManager) session.getWorkspace()

                                                             .getNodeTypeManager();

InputStream is = MyClass.class.getResourceAsStream("mynodetypes.xml");

nodeTypeManager.registerNodeTypes(is,ExtendedNodeTypeManager.IGNORE_IF_EXISTS );

Run time registration using NodeTypeValue

ExtendedNodeTypeManager nodeTypeManager = (ExtendedNodeTypeManager) session.getWorkspace()

                                                             .getNodeTypeManager();

NodeTypeValue testNValue = new NodeTypeValue();


List<String> superType = new ArrayList<String>();

superType.add("nt:base");

testNValue.setName("exo:myNodeType");

testNValue.setPrimaryItemName("");

testNValue.setDeclaredSupertypeNames(superType);

List<PropertyDefinitionValue> props = new ArrayList<PropertyDefinitionValue>();

props.add(new PropertyDefinitionValue("*",

                                      false,

                                      false,

                                      1,

                                      false,

                                      new ArrayList<String>(),

                                      false,

                                      0,

                                      new ArrayList<String>()));

testNValue.setDeclaredPropertyDefinitionValues(props);


nodeTypeManager.registerNodeType(testNValue, ExtendedNodeTypeManager.FAIL_IF_EXISTS);
