I created a java program for connect the HSQLDB , the first one works well,

public final static String DRIVER = "org.hsqldb.jdbcDriver";
public final static String URL = "jdbc:hsqldb:file:F:/hsqlTest/data/db";
public final static String DBNAME = "SA";

but these are not

public final static String DRIVER = "org.hsqldb.jdbcDriver";
public final static String URL = "jdbc:hsqldb:file:C:/Program Files/tich Tools/mos tech/app/data/db/t1/t2/01/db";
public final static String DBNAME = "SA";

the error shows like this:

java.sql.SQLException: error in script file line: 1 unexpected token: ?

I googled this connection question , but most of them not help much, someone says that may be the HSQLDB version problem. The dbase shut down in "SHUT COMPRESS" model. Anyone give some advice?
