secret key not found

[Rupali Chitre]

I am trying to decrypt file from command prompt as below and it works fine.
echo paraphase|gpg --batch --passphrase-fd 0 --decrypt-files *data*.txt.gpg 
 

But the same command when I call from application (Informatica), it gives below error.
>>gpg: encrypted with RSA key, ID AAAAAA
    gpg: decryption failed: No secret key



Is that I need to give some other details ?
