Trust all SSL certificates in Java Playframework 2.2

I am trying to call a web-service(Which has self signed SSL certificate) in Play Framework
Using the following function:

public static play.libs.F.Promise<Result> webcall() {
String feedUrl = "https://10.0.1.1/client/api";
final play.libs.F.Promise<Result> resultPromise = WS.url(feedUrl).get().map(
new Function<WS.Response, Result>() {
public Result apply(WS.Response response) {
return ok("Feed title:" + response.asJson().findPath("title").toString());
}
}
);
return resultPromise;
}


It is throwing the following Error in Logs,

[error] play - Cannot invoke the action, eventually got an error: java.net.ConnectException: General SSLEngine problem to https://10.0.1.1/client/api
[error] application -

! @6fpimpnp6 - Internal server error, for (GET) [/webcall] ->

If I call the service using HttpsURLConnection its working fine by adding

TrustManager[] trustAllcerts = new TrustManager[]{
new X509TrustManager() {

@Override
public X509Certificate[] getAcceptedIssuers() {
// TODO Auto-generated method stub
return null;
}

@Override
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
// TODO Auto-generated method stub

}

@Override
public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
// TODO Auto-generated method stub

}
}};

javax.net.ssl.SSLContext sc = javax.net.ssl.SSLContext.getInstance("SSL");
sc.init(null, trustAllcerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HostnameVerifier allHostsValid = new HostnameVerifier() {

@Override
public boolean verify(String arg0, SSLSession arg1) {
// TODO Auto-generated method stub
return false;
}
};
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);


How to Trust all Selfsigned / Untrusted ssl certificates in Play Framework?

Answer

Try adding the following code to conf/application.conf file

ws.acceptAnyCertificate=true

This will work if you are using the Promise class. But won't work if you are calling the service through other HttpClients.

UPDATE: As of Play Framework 2.5, you should use the following -

play.ws.ssl.loose.acceptAnyCertificate=true

You can do this in development environment, but you should never do this in Production environment, as it can prove as a security threat. In production, instead install the certificates of the client in your keystore.
