Dynamic image showing default image instead of requested image

Question

I'm using CR4E v2.0 to incorporate reports into my application which is built into an ear file and deployed with Jboss 4.2.2 at the moment. I have an image in my report that I am trying to set dynamically from a URL in a database,  but when the report is run only the default image shows up. The URL in the database for the logo is http://localhost:8087/module_Reporting/Logo.gif and I verified that exact string is being returned to the report, but the image is not changing from the default placeholder.
The formula for the graphic location is:
HdrPictureLogoClient : Graphic Location
// Return values: Any string value.
If Not IsNull({REPORT_PARAMETER_FACT.LOGO_URL_PATH})
Then {REPORT_PARAMETER_FACT.LOGO_URL_PATH}
Else "";
I'm using a com.crystaldecisions.report.web.viewer.CrystalReportViewer in my jsp page to display the report and this is the part of the page that handles the viewer
CrystalReportViewer crystalReportPageViewer = new CrystalReportViewer();
// If the report is not saved in the session you just keep getting prompted for parameters
Object reportSource = session.getAttribute("ReportSource");
if (reportSource == null)
     reportSource = clientDoc.getReportSource();
     session.setAttribute("ReportSource", reportSource);
//     set the reportsource property of the viewer
crystalReportPageViewer.setReportSource(reportSource);
// setting the optoins in the Crystal Report toolbar
crystalReportPageViewer.setDisplayGroupTree(false);
crystalReportPageViewer.setHasToggleGroupTreeButton(false);
crystalReportPageViewer.setHasSearchButton(false);
crystalReportPageViewer.setHasRefreshButton(false); 
crystalReportPageViewer.processHttpRequest(request, response, application, null);
The viewer is contained in an iFrame and is disposed of in the containing jsp.
Am I missing something? Any help would be greatly appreciated!

Thank you very much for your reply, but I am not trying to add an image into the report at run time, I am trying to change the source of the image. There is an image in the report as a place holder (called HdrPictureLogoClient) and the code that handles the source of the image is in the .rpt file also as this formula:
HdrPictureLogoClient : Graphic Location
// Return values: Any string value.
If Not IsNull({REPORT_PARAMETER_FACT.LOGO_URL_PATH})
Then {REPORT_PARAMETER_FACT.LOGO_URL_PATH}
Else "";
{/code}
I have discovered that it works just fine with a file path name like C:\logo.png in the database but it does not work with my web URL.
I just find it extra interesting because when the report was originally created in a Crystal Reports Project in myEclipse and deployed as an expanded war directly to jboss running in myEclipse it worked fine, but now that it is being incorporated into an EJB project which is built into an ear file that is deployed in a jboss service running outside of myEclipse it no longer works.
