Hello,
I am sure this topic has been discussed before but I cannot find any thing close to this so I am posting here. Hopefully I will hear back in time.
I am creating a VM with the option "-Djava.class.path=/home/rrp/classes/*" (using java 1.6 libraries). I am getting a NoClassDefFoundError. The classes directory contains jar files and one of the jar file has this class in it. If I list the jar file in CLASSPATH as "/home/rrp/classes/my.jar" it works fine. Is this a bug? OR am I doing something wrong?
Thanks
Raj

Do the following:
echo /home/rrp/classes/* echo echo echo '/home/rrp/classes/*'
Then make sure your command line looks like-Djava.class.path='/home/rrp/classes/*'
with the quotes around the path so that the '*' doesn't get expanded by the shell.
Also, why are you using -D instead of -cp? Does that even work?

nevermind, mis-read

So even if -D is a valid substitute for -cp (which it may or may not be), it might be that -cp will expand the '*' into a proper colon-separated classpath and then set the java.class.path System Property to that expanded value, while specifying the property directly on the command line bypasses that expansion, leaving us with an unexpaded '*' as the (invalid) classpath. I hadn't thought of that.jverd wrote:Wouldn't surprise me if that is the reason the expansion isn't working.
