How can I use a proxy connection within the ArcGIS Runtime Java SDK?

For 100.0, have a look at the static method setProxyInfo on the RequestConfiguration class.

Let us know if this helps.

Thank you for your answer. I already found this class and my next problem is: how and where can / should I implement the setProxyInfo method to add proxy informations?

I don't think it really matters where in your code you put it.

Why do you ask? Are you experiencing unexpected results?

Just let us know. Thanks

I'm not shure how to become access to the RequestConfiguration class.

I don't use ArcGIS android. I use (or try to use) ArcGIS it with Java FX. Your link redirect me to this url "http://android:8080/docs/api/java/doc/api-doc/arcgis-java/reference/com/esri/arcgisruntime/io/RequestConfiguration.html#setProxyInfo(java.lang.String, int)" which I can't open because the host "android:8080" not exist and I'm not hosting anything like that here on my computer.

Hi,

I'm using Quarz with JavaFX and I want to access the ESRI map server over a proxy which requires an authentication.

WIth the ProxySelector properties (e.g http.proxyHost) I could make the SDK using the proxy. But how I can define the authentication's credentials like username and password? The java.net.Authenticator did not work. The method getPasswordAuthentication() is never called.

        Authenticator.setDefault(new Authenticator() {              @Override             protected PasswordAuthentication getPasswordAuthentication() {                 System.out.println("Authentication for " + getRequestingURL());                 if (getRequestorType() == RequestorType.PROXY && "myproxy.intranet.com".equalsIgnoreCase(getRequestingURL().toString())) {                     System.out.println("getPasswordAuthentication() for " + getRequestingURL());                     return new PasswordAuthentication(                             "userId", "password".toCharArray());                 }                 return null;             }         });

I'm trying to access a ArcGISMapImageLayer(http://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer) over a webproxy, which requires a basic authentication with username and password.
I figured out 2 possibilities, but neither the configuration over the java.net.ProxySelector properties like http.proxyHost/http.proxyPort nor the RequestConfiguration.setProxyInfo("webproxy.sbb.ch", 8080, "http") worked as I expected.

I implemented my own AuthenticationChallengeHandler and registered it over the static method

AuthenticationManager.setAuthenticationChallengeHandler(..)

, which is never invoked.

When I set

RequestConfiguration.setProxyInfo("webproxy.sbb.ch", 8080, "https")

then the AuthenticationChallengeHandler is invoked, but instead of the expected USER_CREDENTIAL_CHALLENGE
a SELF_SIGNED_CHALLENGE AuthenticationChallenge is delivered.

The following SSLException had been occured :

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
at sun.security.ssl.InputRecord.handleUnknownRecord(InputRecord.java:710)
at sun.security.ssl.InputRecord.read(InputRecord.java:527)
at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:973)
at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1375)
at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1403)
at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1387)

at com.esri.arcgisruntime.internal.httpclient.conn.b.e.a(SourceFile:353)
at com.esri.arcgisruntime.internal.httpclient.impl.c.e.a(SourceFile:141)

So obviously arcgis establishes a SSL connection to the proxy. Does the AuthenticationChallengeHandler only works with SSL connections or is it a bug?
