PBE with blowfish : is this solution secure

Question

Hi,
I have designed a solution do do PBE with blowfish. Assuming there is no weak keys in Blowfish, and using a 160bits key (due to SHA-1) is this code secure ?
MessageDigest md = MessageDigest.getInstance("SHA-1");         
byte[] password = "here is the password I use !".getBytes();   
byte[] key = md.digest(password);                                // hash the password on 160bits
SecretKeySpec skspec = new SecretKeySpec(key, "Blowfish");       // prepare the key for the cipher
Cipher cipher = Cipher.getInstance("Blowfish/ECB/PKCS5Padding"); // create the cipher
cipher.init(Cipher.ENCRYPT_MODE,skspec);
byte[] someCipherText = cipher.doFinal(somePlainText);           Thanks
Oliver.

Also, Sun should better add public final static constants in the String class to have the names of encodings supported on all platforms:
class String {
    public static final String ASCII = "US-ASCII";
    public static final String ISOLAT1 = "ISO8859_1";
    public static final String UTF8 = "UTF-8";
}This would be a strong sign that at least these minimum encodings will be supported. Alternatively, these constants could be placed in a separate new class or interface (named for example Encoding).
May be there should exist a valid value allowing to specify explicitly the native platform encoding if we still need it.
    public static final String NATIVE;Then there would be no more excuse to not use an explicit encoding:
    byte[] buffer = new byte[] { (byte)64, (byte)65 (byte)66 };
    String abc = new String(buffer, Encoding.ASCII); // returns a string equal to "ABC"
    buffer = new byte[] { (byte)0xc4, (byte)0x80, (byte)0 };
    abc = new String(buffer, Encoding.UTF8); // returns a string equal to "\u0100\u0000"
