    HttpProxyServlet and user authentication

    I see the params for proxyHost and proxyPort but I don't see anything for username and password - I'm assuming these don't exist?

    Some of our clients have proxies that require user authentication for external addresses.

    That's lower-level, it's JVM-wide settings - see this article.

      Thanks again! As usual, most of the perceived shortcomings of SmartGwt usually end up being our lack of general webapp knowledge. You guys rock. Thanks.

        Hi

        I am trying out the showcase example in my organization and the internet proxy causes the WSDL Databinding sample to fail
        I have tried to set the username and password by specifying VM options and also tried specifying the properties in the server.properties file but it still fails.

        server.properties
        Code:
        http.proxySet=true
http.proxyHost=proxyHostNameValue
http.proxyPort=proxyPortValue
http.proxyUser=myusername
http.proxyPassword=mypassword

        My logs

        If I run a simple Java application without SmartGWT, it takes the proxy setting including the username and password when I specify it as command line arguments.

        So where exactly should I specify the username and password to get the WSDL Databinding example to work? I have tried passing it as VM arguments, putting it in the server.properties file but it just doesnt get picked up..

          Take a look at the article linked above - these are Java system properties, outside of the domain of SmartGWT entirely. You would set them via one of the techniques mentioned in that article. server.properties is for SmartGWT properties, so not relevant here.

          Our HttpProxyServlet does have some limited support for configuring proxies that do not require authentication, but the recommended approach is to again to set this at the Java system level, both because of your requirement for authentication and because it means that general Java usage (such as the URL class) will use your proxy settings.
