Hi, I get an error executing this code

DatabaseMetaData dmd = conn.getMetaData();
ResultSet rs = dmd.getTables(null, null, "%", new String[] {"TABLE"});

java.sql.SQLException: GDSException: org.firebirdsql.gds.GDSException:
Dynamic SQL Error
SQL error code = -901
feature is not supported
at
org.firebirdsql.jdbc.FBPreparedStatement.<init>(FBPreparedStatement.java:89)

org.firebirdsql.jdbc.FBConnection.prepareStatement(FBConnection.java:178)

org.firebirdsql.jdbc.FBDatabaseMetaData.getStatement(FBDatabaseMetaData.java

org.firebirdsql.jdbc.FBDatabaseMetaData.doQuery(FBDatabaseMetaData.java:4189
)
at
org.firebirdsql.jdbc.FBDatabaseMetaData.getTables(FBDatabaseMetaData.java:20

Hovewer, I don't think it is firebird that dose not support that feature,
since the same code with interclient works.
Are there any alternatives?
