    Hi,

    I have got below error while retrieving extended types and registering
    custom type.

    org.apache.cayenne.CayenneRuntimeException: [v.3.0RC3 Mar 29 2010 13:42:23]
    Error detecting database type: Login failed for user
    'winnt://machine1/administrator'.

    Code lines where I got the error is below.
    ---------------------------------------
    Actually there is no datasource set during initialization of DataDomain. I
    am dynalically setting DataSource within a servlet filter. Error is returned
    while executing getExtendedTypes() method in the last line of code snippet.

    DataNode dn = dataDomain.getNode(CommonAppConstants.CAYENNE_DATA_NODE);

    // create custom ExtendedType instance
    ExtendedType customType = new MdbUuidType();

    // set the data source based on user database type
    dn.setDataSource(DBPool.getDataSource(md));
    dn.getAdapter().getExtendedTypes().registerType(customType);

    any idea what went wrong? getExtendedTypes() works fine if data source is
    created during initialization via xxxx.driver.xml configuration.
