Dynamic jnlp - automatic launch

Question

I realize there are some posts on this topic, but nothing recent and nothing particularly concrete. Any insight is much appreciated.
I am dynamically building a jnlp so that I can pass dynamic arguments into my webstart app. I am getting the file download dialog that asks me to either open or save my jnlp file. I am running Tomcat 6. I am using https. I have played with various settings based suggesstions in these forums. My response object looks like this:
resp.setHeader("Content-disposition", "attachment; filename=supply.jnlp"  );
            resp.setHeader("Cache-Control", null);
            resp.setCharacterEncoding(null);
            resp.setHeader("Set-Cookie", null);
            resp.setHeader("Vary", null);
            resp.setDateHeader("Last-Modified", new Date().getTime()); my web.xml looks like this:
<servlet>
     <servlet-name>SupplyJNLPServlet</servlet-name>
     <servlet-class>mil.atc.supply.servlet.SupplyJnlpBuilderServlet</servlet-class>
</servlet>
<servlet-mapping>
     <servlet-name>SupplyJNLPServlet</servlet-name>
     <url-pattern>/SupplyJNLP</url-pattern>
</servlet-mapping>
<servlet>
     <servlet-name>JnlpDownloadServlet</servlet-name>
     <display-name>JnlpDownloadServlet</display-name>
     <servlet-class>jnlp.sample.servlet.JnlpDownloadServlet</servlet-class>
</servlet>
<servlet-mapping>
     <servlet-name>JnlpDownloadServlet</servlet-name>
     <url-pattern>*.jnlp</url-pattern>
</servlet-mapping>
<mime-mapping>
     <extension>jnlp</extension>
     <mime-type>application/x-java-jnlp-file</mime-type>
</mime-mapping>
The jnlp mime type is configured on my IIS server - I am using the Apache ASAPI filters.
Once again, thanks for any help.

dcfrank65, or anyone else... did you ever discover a solution to this problem?
I too have an issue whereby opening a dynamically generated jnlp file over HTTP works fine, but opening it over HTTPS causes IE to prompt whether the file should be opened or saved. As you already discovered, there do seem to be quite a few threads covering this topic, but none with a definitive answer. In my case, the JNLP file is being rendered by ASP.NET code running on IIS.
For the record, at the risk of becoming immediately unpopular (!), AndrewThompson64's comment about how dcrank65 failed to ask a question seems unnecessarily obtuse, since dcfrank65 did previous say:
"I don't want to be prompted to open or save, I want my jnlp file to be executed and the webstart application to run with no further action from my user. +So I am asking for ideas to accomplish this+."
This is a fairly clear and concise request for information, regardless of whether it was phrased as a question. So, dcfrank's response, though a little strong, seems justified.
