Hi , Iam trying to enable mutual authentication for an application which is deployed on the JBoss 4.04 . Iam following the steps mentioned in the guilde - http://wiki.jboss.org/wiki/Wiki.jsp?page=SSLSetup . In this guide there are lot of configurations being mentioned iam essentially trying the (3) one SSL Enabled on teh server with self signed certs WebBrowser client . I tried all the steps mentioned here and i ran into few issues . On connecting from IE to the application which is deployed iam getting a No trusted Certificate exception. ... 30 more Caused by: sun.security.validator.ValidatorException: No trusted certificate found at sun.security.validator.SimpleValidator.buildTrustedChain(SimpleValidator.java:304) at sun.security.validator.SimpleValidator.engineValidate(SimpleValidator.java:107) at sun.security.validator.Validator.validate(Validator.java:203) at com.sun.net.ssl.internal.ssl.X509TrustManagerImpl.checkServerTrusted(X509TrustManagerImpl.java:172) at com.sun.net.ssl.internal.ssl.JsseX509TrustManager.checkServerTrusted(SSLContextImpl.java:320) at com.sun.net.ssl.internal.ssl.ClientHandshaker.serverCertificate(ClientHandshaker.java:841) I googled about this and did some more things also i have exported the server certificate to the jdk cacerts file even then this error continues to exist. Can you explain why iam running into this issue . Any Help wil be highly appreciated Many Thanks Chandra View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4070453#...
