Cannot delete reports, unless I close and open Eclipse/Tomcat

Question

Please can someone help me.
I cannot delete reports. I have not worked out all the details yet but this is what I got so far...
First I thought it was a problem with my tomcat setup, I would deploy my WAR and run the app. After
viewing the report and closing the browser. I would not beable to delete the rpt file until I close Tomcat.
I have now got a similar problem within Eclipse. (as far as I can tell its the same problem but even worse)
If i create any report and design it or even a new blank report. And not do anything to it, just save it as a blank report. I then try delete the
report. Right click and then delete.
After a few seconds Eclipse brings up an error and says it cant delete the file, the reason it gives is
Problems encountered while deleting resources.
  Could not delete 'C:\WorkSpace\Project\WebContent\Report1.rpt'.
    Problems encountered while deleting files.
      Could not delete: C:\WorkSpace\Project\WebContent\Report1.rpt.
I have tried creating a fresh new project and only one report. And I still get the error.
If I try delete the whole project perminatly it also gives the same error. (But deletes the default crystal report)
I have to close Eclipse and then open it again before I can delete the rpt files properly.
I have not always had this problem. It used to work fine (dont ask what I have done since
cause I would not beable to tell, sorry)
Hopefully someone can help me, as this is driving me insane, and having to stop and start Tomcat every
time I want to deploy a new test version is not really an option.

Hi Merry,
Thanks for getting back to me.
My reports within Eclipse seem to be behaving themselves now and dying gracefully without and hassles,
so I dont know what fixed that problem as I have not made any changes or done any updates. One of
those things I guess.
With regards to TOMCAT still having a handle on the reports, As far as I am aware I am putting the
report source in session
Below is my JSP that loads the report
I store report name in session via a servlet and set all the DB connection details in the servlet also.
imports....
try {
   String reportName = session.getAttribute("Report").toString();
   ReportClientDocument clientDoc = (ReportClientDocument) session.getAttribute(reportName);
   if (clientDoc == null) {
      clientDoc = new ReportClientDocument();
      // Open report
      clientDoc.open(reportName, OpenReportOptions._openAsReadOnly);
      // ****** BEGIN LOGON DATASOURCE SNIPPET **************** 
         //Call the process to set all the database detail retrieved from web.xml
         // Custom function to set the connection details
         ReportFunctions.setConnection(clientDoc);
      // ****** END LOGON DATASOURCE SNIPPET ****************           
      // Store the report document in session
      session.setAttribute(reportName, clientDoc);
   // ****** BEGIN CONNECT CRYSTALREPORTPAGEVIEWER SNIPPET **************** 
      // Create the CrystalReportViewer object
      CrystalReportViewer crystalReportPageViewer = new CrystalReportViewer();
      //set the reportsource property of the viewer
      IReportSource reportSource = clientDoc.getReportSource();                    
      crystalReportPageViewer.setReportSource(reportSource);
      // set viewer attributes
      crystalReportPageViewer.setOwnPage(true);
      crystalReportPageViewer.setOwnForm(true);
      crystalReportPageViewer.setDisplayGroupTree(false);
      crystalReportPageViewer.setHasToggleGroupTreeButton(false);
      crystalReportPageViewer.setHasPrintButton(false);
      crystalReportPageViewer.setEnableDrillDown(false);
      // Process the report
      crystalReportPageViewer.processHttpRequest(request, response, application, null);
   // ****** END CONNECT CRYSTALREPORTPAGEVIEWER SNIPPET ****************          
   } catch (ReportSDKExceptionBase e) {
    out.println(e);
So far its very basic.
How best can I kill and clean up once the web page is closed. I have tried a few options but dont seem to
know the best way,
I tried "onbeforeunload" but I dont know if this is the best practice,
I have a session listener with sessionDestroyed but have not learnt how to envoke this correctly, or atleast when to correctly call it. And then I dont know how to clean out any loaded reports from here.
I have used 
request.getSession().invalidate();
at the end of my JSP but that destoys everything everytime a user does anything on the page, (selecting any of the buttons on the report)
I am still learning everyday, and so I appoligise for questions that I should really know, am being pushed into the deep end here so trying my best :).
Thanks again.

Sorry for bumping this back the list, but I am at my wits end as how best to "clean out" the reports
once they have been closed or timed out.
Surely there must be a way to release all objects (be it a actaul rpt file or the classes12.jar) once the
reports have been viewed and closed.
Even if there is something I can load via another servlet that destroys anything that has to do
with the main website.
Thanks and again sorry for moving this back up the list. If i get no replies, ill assume this is impossible
and that the only way to upload a new version of a report is to shut the whole Tomcat service and
make the changes.
Cheers
