Java Applet Constantly Asks for Authentication

Question

With have a ADF application on Weblogic 10 that has occasional access to a Java applet. The Java applet is loaded whenever it's needed and not loaded whenever it isn't. The applet is currently in the public_html/applet folder.

When we set the SSL configuration to requiring a client certificate, when the Java applet loads, it'll constantly ask for a client certificate:

Request Authentication Identification required. Please select certificate to be used for authentication.

This is annoying to users and the Java Applet doesn't need authentication. Is there any way we can disable the authentication or remove the prompt?

Here's the embedded applet code:

Edit: Things I've already tried:

1) Setting the Applet up on HTTP instead of HTTPS; I get a warning about mixed content and still get the authentication pop-up.

2) Created a minimal applet that only types out "HELLO WORLD" in the console, still get the authentication pop-up

Here's the console window:

Solution 3

Since our application is on http and https, I just set the archive to http:// and it works fine now.

OTHER TIPS

You said that your applet not requires client authentication so you can put your applet jars on http location. Then you have to specify the codebase parameter to this http location. For example if you put your jar as a resource on 

http://public.test/somewhere/myApplet.jar
you can specify:

codebase = http://public.test/somewhere/
archive = myApplet.jar

However I think that this is probably a configuration issue, you can configure your web server to request a client certificate authentication optionally an not required on applet location.

Hope this helps,

EDIT:

You can put your webLogic behind a proxy (like apache http server), an configure proxy to require the client certificate only in a specific location. A configuration sample for apache http server case looks like:

##
## SSL Virtual Host Context
##
<VirtualHost myHost:443>
    SSLEngine on
    SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
    SSLCertificateFile conf/server.crt
    SSLCertificateKeyFile conf/server.key
    SSLVerifyClient none
    SSLVerifyDepth 10
    SSLOptions +StdEnvVars +ExportCertData

    JkMount /myWeb loadBalancer
    JkMount /myWeb/* loadBalancer

    <Location /myWeb/login/certificateLoginLocation>

        SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
        SSLCACertificateFile conf/trustedCA.cer
        SSLVerifyClient optional
        SSLVerifyDepth 10
        SSLOptions +StdEnvVars +ExportCertData +OptRenegotiate

        RewriteEngine on
        RewriteCond %{SSL:SSL_CLIENT_VERIFY} !^SUCCESS$
        RewriteRule .* http://myHost/myWeb/accesForbbiden.htm

    </Location> 


</VirtualHost>

well, i not sure about weblogic, i am using jboss and i know that there is no way to do this.

so what we did is install an apache in front, served as reverse proxy

and the configuration look 

Listen vgw_mgmt:443
<VirtualHost vgw_mgmt:443>
    DocumentRoot /srv/www/
    SSLEngine on
    SSLCipherSuite HIGH
    SSLProtocol all -SSLv2
    SSLOptions +ExportCertData +StdEnvVars
    SSLCertificateFile /etc/httpd/ssl/server-mgmt.pem
    SSLCertificateKeyFile /etc/httpd/ssl/server-mgmt.key
    SSLVerifyDepth 3
    SSLCACertificateFile /etc/httpd/ssl/trustedca-mgmt.pem
    SSLVerifyClient none    

    ProxyPass /webmgr/   ajp://webapps:8009/webmgr/

    <Location /webmgr/>
    SSLVerifyClient optional
    </Location>

    <Location /webmgr/javascript/>
    SSLVerifyClient none
    </Location>

</VirtualHost>

so, whenever user hit https : // pro xy /webmgr/, client authentication is prompt (the reason we use "optional" instead of "required", is because we want to display nice error page tell customer you need to provide cert to login)

and, my applet stored inside /webmgr/javascript/applet.jar

so when applet load

<applet archive="applet.jar" codebase="/webmgr/javascript/" name="jsapplet" id="jsapplet" code="myapps.mylittleprogram" height="1" width="1"></applet>

it will skipped the client authentication.
