NullPointerException creating a new platform instance using hsqld b

[Christian . Eugster]

Hi,

I try to use an hsqldb database in my application. The following code throws
a NullPointerException at the last line (>):

        Class.forName( "org.hsqldb.jdbcDriver" );
        org.hsqldb.jdbc.jdbcDataSource ds = new
org.hsqldb.jdbc.jdbcDataSource();
        ds.setDatabase(db.getName());
        ds.setUser("sa");
        ds.setPassword("");
>       Platform platform = PlatformFactory.createNewPlatformInstance(ds,
"sa", "");

The hsqldb server ist running...

The Exception:

Exception in thread "main" java.lang.NullPointerException
        at
org.apache.ddlutils.PlatformUtils.determineDatabaseType(PlatformUtils.java:2
48)
        at
org.apache.ddlutils.PlatformFactory.createNewPlatformInstance(PlatformFactor
y.java:136)
        at
ch.eugster.extraction.DatabaseCreator.initDatabase(DatabaseCreator.java:35)
        at ch.eugster.extraction.Main.<init>(Main.java:38)
        at ch.eugster.extraction.Main.main(Main.java:51)

Has anybody a suggestion where the problem lies?

Thanks

Christian
