Java Security

Hi, everybody i m using the j2sdk1.4.2_03
I am trying to run my PBE program but i get the following error:

Exception in thread "main" java.security.NoSuchAlgorithmException: Algorithm PBEWithSHAANDTwofish-CBC not avai
lable
at javax.crypto.SunJCE_b.a(DashoA6275)
at javax.crypto.SecretKeyFactory.getInstance(DashoA6275)
at PBE.encrypt(PBE.java:42)
at PBE.main(PBE.java:29)

Here's the deal.
I have done the following:
I have downloaded the bouncycastle for jdk 1.4 from bouncycastle.org.I read somewhere in there that i also had to download and change the jurisdiction.jar policy files shpped in the jce.Ive done that too. I have also pasted the .jar file bouncycastle after i jarred it myself in the jre both in j2sdk as well as C:\program files\java\security.
However, after having done all that i still keep getting the same error
What am i doing wrong?Is there a complete proper site that tells u exactly what to do as to how to add this provider??
Do i perhaps need to include the bouncycastle provider in my code as well???
Please give me some hints on that one.Its really urgent

Thanks
