org.xmldb.api.base.Collection
A Collection represents a collection of Resources stored within an XML database. An XML database MAY expose collections as a hierarchical set of parent and child collections.
A Collection provides access to the Resources stored by the Collection and to Service instances that can operate against the Collection and the Resources stored within it. The Service mechanism provides the ability to extend the functionality of a Collection in ways that allows optional functionality to be enabled for the Collection.


        collection.removeResource(newResource);
    }


  public void testRemove() throws Exception {
    Collection collection = client.getCollection(TEST_COLLECTION_PATH);
    if (collection == null) {
      throw new Exception("getCollection(" + TEST_COLLECTION_PATH + ") returned null");
    }


    /*
     * Create a binary resource, save it in the 'current' collection,
     * then remove it and verify that it was indeed removed.
     */


        Resource newResource = collection.createResource(null, "BinaryResource");
        newResource.setContent(new byte[] { 0x00, 0x10, 0x01, 0x11 });
    collection.storeResource(newResource);
    String id = newResource.getId();


    Resource foundResource = collection.getResource(id);
    assertNotNull("It should be in there", foundResource);


        collection.removeResource(foundResource);
        foundResource = collection.getResource(id);
        assertNull("It should not be in there anymore", foundResource);
