I am using Metro to implement security in a contract-first web service. But I am facing the following problem. When i use "Edit web service attribute" option in client, i couldn't find "Security" option in "quality of service" tab. I find only "Transport" tab. I am using Netbeans 6.0.1. I have also developed code-first web service. It worked quite well but facing problem in contract-first service. I have spent my two days to resovle this problem but invain . Please help me.
