That sounds like the equivalent of a FileNotFoundException.
ie you have told it the rpt file to load, and it can't find it.
1 - check the spelling of the filename
2 - where have you put the file?
3 - What is your config for this?
Do you have CRConfig.xml (Crystal 11) or CrystalReportEngine-config.xml(Crystal 10) in your WEB-INF/classes directory?
That file tells it where to find the rpt files.
I think the default is WEB-INF/lib for some reason.
I keep my reports in the WEB-INF/reports directory
Mine looks something like this:
<?xml version="1.0" encoding="utf-8"?><CrystalReportEngine-configuration>
    <reportlocation>../reports</reportlocation>
    <timeout>10</timeout>     
<keycode>[insert your keycode here]</keycode>
</CrystalReportEngine-configuration>Hope this helps,
