Once you have AutoVue Client/Server installed and configured with your ISDK integration.
Open a file in the AutoVue client and look at the HTML code of the client applet.
Inside the applet tag, you will find the DMSARGS and all the properties that are sent with it.
For example, if you see the following properties:
<PARAM NAME="DMS" VALUE="http://host:port/servlet/VueLink">
<PARAM NAME="DMSARGS" VALUE="DMS_USERNAME;DMS_PRESERVE_COOKIES;LOCALE">
<PARAM NAME="DMS_USERNAME" VALUE="george_av">
<PARAM NAME="DMS_PRESERVE_COOKIES" VALUE="true">
<PARAM NAME="LOCALE" VALUE="EN">
Then you can add DMS_USERNAME and the LOCALE the property file you created in the AutoVue WS deployment.
It is described in the Install & config guide on page 11-12: http://docs.oracle.com/cd/E37443_01/otn/pdf/E37350_01.pdf
If your DMS argument cannot be hard-coded on the server, you may use the AuthorizationProxy.DmsArguments class to add additional parameters.
This may make sense for the username for example. But most integrations use the username from the autentication uname/passwd pair instead of receiving a separate parameter.
