ok did an external client in java and i did produce a jar that call the webservice
after i did this for call the webserice inside the aspx page:

       System.Diagnostics.Process proc = new System.Diagnostics.Process();
        proc.StartInfo.RedirectStandardOutput = true;
        proc.StartInfo.RedirectStandardError = true;
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.FileName = "\"" + System.Web.HttpContext.Current.Server.MapPath(".") + "\\"  + "ConsoleApp.jar" + "\"" ;

        if(datarepo != "")
        proc.StartInfo.Arguments = "\""+connectionString +"\"" + " " +"\"" +reportname+"\""  + " " +"\"" +datarepo+"\""  + " " +"\"" +opco+"\""  + " " + "\"" +ambienteParm+"\"";
        else
        proc.StartInfo.Arguments = "\""+connectionString +"\"" + " " +"\"" +reportname+"\""  + " " +"\"" + "\""  + " " +"\"" +opco+"\""  + " " + "\"" +ambienteParm+"\"";

        proc.Start();
        proc.WaitForExit();
        //string result = proc.StandardOutput.ReadToEnd();
        //Response.Write(result + " - "  + proc.ExitCode);
        proc.Close();
