Dan, You are correct the directory is specified in the FAQ.
I should have corrected the classpath before sending the email. I wish fixing the problem was that simple. I had already tried the directory without success. I then tried the file just in case I had misinterpreted the FAQ. I corrected the classpath to the directory and tried again. Same error as before. > Please read the FAQ more closely, you need the DIRECTORY where the > properties file is located in your CLASSPATH, NOT the file. > > On Thu, Feb 14, 2008 at 7:09 PM, java4me <[EMAIL PROTECTED]> wrote: > >> Dan, >> >> Here is the info you requested. >> >> >> >> You downloaded the properties file but java still can't find it? >> That is correct. >> >> >> >> What does "echo $CLASSPATH" show? >> >> [EMAIL PROTECTED]:/TestShare/FindUsbDevice/src/findusbdevice# echo >> $classpath >> /opt/javax-usb/lib:/opt/javax-usb/etc/javax.usb.prperties >> >> >> >> What directory is the properties file in? >> >> [EMAIL PROTECTED]:/opt/javax-usb/etc# dir >> >> javax.usb.properties >> >> >> Where did you get the properties file? >> >> >> http://downloads.sourceforge.net/javax-usb/javax-usb-1.0.1-1.i386.rpm?modtime=1135006365&big_mirror=0 >> >> >> What is the contents of the properties file? >> >> >> # >> >> # Properties file for javax.usb >> >> # >> >> # This file is provided by the Linux implementation of javax.usb. >> >> # >> >> # The 2.4 kernel does not support control-type queueing nor interrupt-type >> >> # queueing (see below to enable javax.usb internal queueing). >> >> # >> >> # Some 2.4 kernels do not properly handle hotplug notification, specifically >> >> # those somewhere after 2.4.19.
