"keyStore" in EJB Module problem

Hi,

I'm testing with X.509 on SAP PI 7.4 SP08 , I could sign, verify, encrypt and decrypt values in a UDF.

I have copied and pasted the code in a module ( EJB 3.0 ) and is not working, below is the code to encrypt:

public byte[] encrypt(byte[] inpBytes, String keyStorageView, String keyStorageEntry,String SubjectDN) throws Exception {        KeyStore keyStore = null;    boolean res = false;    ByteArrayInputStream is = null;    SsfDataPKCS7 data = null;    byte[] result = null;    InitialContext ctx = null;    ctx = new InitialContext();    Object o = null;    o = ctx.lookup("keystore");    KeystoreManager manager = (KeystoreManager)o;    keyStore = manager.getKeystore(keyStorageView);//in debugging mode I see no certificates!    is = new ByteArrayInputStream(inpBytes);    data = new SsfDataPKCS7((InputStream)is);    SsfPabKeyStore profile;    profile = new SsfPabKeyStore(keyStore);    SsfSigRcpList test = new SsfSigRcpList();    test.add(new SsfSigRcpInfo(profile.getCertificateBySubjectDN(SubjectDN)));//null value in "profile.getCertificateBySubjectDN(SubjectDN)"    res = data.encrypt(test,(ISsfPab)profile);    if (res) {      result = (byte[])data.getDataPKCS7();    }    return result;  }

Any ideas?.(I think it's a bug).

Best regards.
