Ubuntu Linux 8.04 ("Hardy Heron")
External program for PDF viewer is set to "/usr/bin/acroread". When the report is run, acroread starts, but gives the message "There was an error opening this document. The file cannot be found."
ps aux shows /lib/ld-linux.so.2 /usr/lib/Adobe/Reader8/Reader/intellinux/bin/acroread "/mnt/common/netbeans/reports/src/com/weycogroup/reports/order/OrderReport.pdf".
The PDF does exist at that path and can be opened by entering "acroread /mnt/common/netbeans/reports/src/com/weycogroup/reports/order/OrderReport.pdf" from the command line.
