The easiest way to get the correct database object is:

Database database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(connection);

Thanks for that. There are certainly less errors, however, a 'Database' parameter seems to be necessary for the Liquibase constructor. From the JavaDocs I see that a Database object can be constructed with one of the subclasses of that interface (e.g. MSSQLDatabase) to which I pass a connection. I will attempt that. If there is anything I'm missing, please do not hesitate to rectify.<br/>Thanks for you continued excellent assistance.<br/>Duke. Yep. Thanks for that.

We did some fairly major refactoring, especially around the Migrator and XML parser classes.

The liquibase.migrator.Migrator class has been moved to liquibase.Liquibase as it is now mainly a facade around the entire LiquiBase engine, rather than just for migrating the database.

The interface to it has also been cleaned up considerably, your code should now be something like this:

try
{
Class.forName(jdbcDBdriver);
Connection connection =
DriverManager.getConnection(
dbUrl,
txtfldUser.getText(),
new String(
passwordField.getPassword()));

Liquibase liquibase =
new Liquibase(xmlFileName,
new ClassLoaderFileOpener());
liquibase.update(null);

}
catch (Exception e)
{
System.out.println(
e.getMessage());
}

Let me know if you have any troubles.

I've downloaded the Liquibase 1.5.0 library and have also included it in my current project as I've been expecting some of the bug-fixes since 1.4.1. I used to be able to execute the following Java code snippet, but now that doesn't run any more. I have not found any documentation yet, but I have realised that the Migrator class no longer exists. Is that correct?<br/>Anyway, here's the code that won't run. Any ideas?<br/><br/>try<br/>{<br/> Class.forName(jdbcDBdriver);<br/> Connection connection =<br/> DriverManager.getConnection(<br/> dbUrl,<br/> txtfldUser.getText(),<br/> new String(<br/> passwordField.getPassword()));<br/><br/> Migrator migrator =<br/> new Migrator(xmlFileName,<br/> new ClassLoaderFileOpener());<br/> migrator.init(connection);<br/> migrator.setMode(<br/> Migrator.Mode.EXECUTE_MODE);<br/> migrator.migrate();<br/><br/>}<br/>catch (Exception e)<br/>{<br/> System.out.println(<br/> e.getMessage());<br/>} Hi there Nathan.

Anyway, here’s the code that won’t run. Any ideas?

Migrator migrator =
new Migrator(xmlFileName,

migrator.init(connection);
migrator.setMode(
Migrator.Mode.EXECUTE_MODE);
migrator.migrate();

}
