Any idea why I am having this exception when trying to create a Pool?
Following is the code (the funny thing is when I execute this application in
my ant task this does not happen):

String maquina = T.setServerPath();
String user = "SYSDBA";
String pwd = "masterkey";
String dir_db = "C:\\LamiSis\\dados\\LAMIDADOS.GDB";
String url =
"jdbc:firebirdsql:"+maquina+"/3050:"+dir_db+"?lc_ctype=ISO8859_1";
System.setProperty("FBLog4j", "true");
ds = new org.firebirdsql.pool.FBWrappingDataSource();
ds.setDescription ("Conexao da LamiPrint");
ds.setType("type4");
ds.setSqlRole("USER");
ds.setEncoding("ISO8859_1");
ds.setCharSet("ISO8859_1");
ds.setUserName(user);
ds.setPassword(pwd);
ds.setLoginTimeout(20);
ds.setMaxConnections(150);
ds.setMinConnections(5);
ds.setNonStandardProperty("isc_dpb_sql_dialect","3");
ds.setDatabase(maquina+"/3050:"+dir_db);


java.sql.SQLException: Unknown character set ISO8859_1
