when I test a example as follow:
...
public void testAdd() throws Exception{
InputStream is = ClassLoader.getSystemResourceAsStream("company.xsd");
List types = XSDHelper.INSTANCE.define(is, null);
is.close();
Type companyType = TypeHelper.INSTANCE.getType("company.xsd",
"CompanyType");
DataObject company = DataFactory.INSTANCE.create(companyType);
company.setString("name", "ACME");
company.setString("id", "E0001");
dao.add(company);
}
...
public void add(final DataObject object) {
this.getJdbcTemplate().execute(new ConnectionCallback(){
public Object doInConnection(Connection conn) throws SQLException,
DataAccessException {
conn.setAutoCommit(false);
DAS das = DAS.FACTORY.createDAS(getConfig(object), conn);
das.applyChanges(object);
return object;
}
});
}
How can I correct it?
