"Access denied" when opening report on RAS Server

Question

I'm sure I'm doing something wrong, but I've only been able to open a report using the rassdk protocol from the server where my java code is running.    This is fine, but I was hoping for efficiency sake that I could have reports reside on the RAS server itself.
My ras server definitely has a Crystal report called EBTest.rpt in the c:\temp directory.  I run this code...
ReportClientDocument rcd = new ReportClientDocument();
rcd.setReportAppServer(ReportConstants.RAS_HOST);
rcd.open("c:\\temp\\EBTest.rpt", OpenReportOptions._openAsReadOnly);
rcd.close();
According to the JavaDoc, this should work, but I get this error ...
Caused by: com.crystaldecisions.sdk.occa.report.lib.ReportSDKServerException: Access denied. Please check directory setting for files you can access.---- Error code:-2147467259 Error code name:failed

     at com.crystaldecisions.sdk.occa.report.application.ReportClientDocument.a(Unknown Source)
     at com.crystaldecisions.sdk.occa.report.application.ClientDocument.open(Unknown Source)
Am I missing something trivial?  
Thanks,
Eric

Answer 1

Now that I've got it working, I expected that the RAS-local approach would be much faster than the RAS-remote, but I didn't find that to be the case in a quick test that I did.  Is this what you'd expect?  Or is there a different part of the ReportClientDocument interaction that would be more efficient. 
From what I've seen, the ReportClientDocument construct and open() are one of the expensive aspects of the report rendering.
Enclosed are the results from a test I did:
--PERF--20 iteration test for 'Test local report initialization'
--PERF--WARMED UP in 3359 ms
--PERF--,Iterations          ,Total Time (mS)     ,Avg(ms)/Iteration   ,Transactions/sec   
--PERF--,20                  ,35515               ,1775.75             ,0.5631423          
--PERF--20 iteration test for 'Test remote report initialization'
--PERF--WARMED UP in 1828 ms
--PERF--,Iterations          ,Total Time (mS)     ,Avg(ms)/Iteration   ,Transactions/sec   
--PERF--,20                  ,37109               ,1855.45             ,0.5389528          
And here's the bulk of the code that generated those results...
int numIterations = 20;
PerformanceUtils.runPerformanceTest("Test local report initialization", numIterations, new Command(){
     public void execute() {
          try{
               ReportClientDocument rcd = new ReportClientDocument();
               rcd.setReportAppServer(ReportConstants.RAS_HOST);
               rcd.open("D:\\Program Files\\Business Objects\\BusinessObjects Enterprise 12.0\\Samples\\EN\\Reports\\triCalendarPeriod___-___Find___-___Months.rpt", OpenReportOptions._openAsReadOnly);
               rcd.close();
          }catch(Exception e){
               throw new RuntimeException(e);
PerformanceUtils.runPerformanceTest("Test remote report initialization", numIterations, new Command(){
     public void execute() {
          try{
               ReportClientDocument rcd = new ReportClientDocument();
               rcd.setReportAppServer(ReportConstants.RAS_HOST);
               rcd.open("rassdk://./test/data/crystal/triCalendarPeriod___-___Find___-___Months.rpt", OpenReportOptions._openAsReadOnly);
               rcd.close();
          }catch(Exception e){
               throw new RuntimeException(e);
