gcc 4.0 and JCE

[Stefan Prelle]

Hi folks,

Maybe I'm just to blind to see what is missing, but I have a problem
when building a native binary that uses the JCE. When executing a
program that obtains a Mac using Mac.getInstance(..) this works when
using gij and fails with a NoSuchAlgorithmException when executing the
native binary.

--------Test programm--------------
import javax.crypto.*;

public class JCETest {
    public static void main(String[] args) throws Exception {	
	Mac mac = Mac.getInstance("HMAC-MD5");
	System.out.println("found "+mac);
    }    
}
-----------GIJ output-------------------

cowabunga->gcj  -C JCETest.java
cowabunga->gij -classpath . JCETest
found javax.crypto.Mac@13ad20

-----------Binary output----------------

cowabunga->gcj -o jcetest --main=JCETest JCETest.java
cowabunga->./jcetest
Exception in thread "main" java.security.NoSuchAlgorithmException: HMAC-
MD5
   at javax.crypto.Mac.getInstance(java.lang.String)
(/usr/lib/libgcj.so.6.0.0)
   at JCETest.main(java.lang.String[]) (Unknown Source)

   at gnu.java.lang.MainThread.run() (/usr/lib/libgcj.so.6.0.0)

----GCC version---------------------

cowabunga->gcc -v

What am I doing wrong ?
