Problem in XML Signature

Question

Hi,
i get an Exception in Registering mechanism for XML Signature factory
it says.
javax.xml.crypto.NoSuchMechanismException : Cannot find DOM Mechanism type
I use J2sdk1.4.2_05 with JWSDP 1.4
Following is the code do let me know where i go wrong.
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.w3c.dom.Document;

XMLSignature signature = fac.newXMLSignature(si, ki);
signature.sign(dsc);
}catch(Exception e){e.printStackTrace();}
public static void main(String[] q)
System.out.println("Creating XML Signatures.....");
XMLSign xs = new XMLSign();
xs.signTheMarkup(q[0]);
Thnx in Advance

I have encountered the same problem. I am using Jbuilder 5 with JDK 1.3.0. I copied all the JAR files of jwsdp-1.5 by creating a custom library.
Even then It didnt work. Can some one who has resolved this please help.
I have tried running the same code in JDeveloper 10g (10.1.2) and got a same error.
