Unable to run a java file
Hi
I am trying to execute a java file(attached), it compiles fine but when I
try to run it I get a ClassNotFoundException.
It used to run smoothly till a week ago, but probably I have something
missing in my environment which I am not able to figure out.
Can anybody help
Thanks

It doesn't look like you have "." in that classpath. If the class DerbyPreparedStatement.class
is the one that you got the ClassNotFoundException on, then I don't think it's in
any of those jars.
Try doing:
set CLASSPATH=.;%CLASSPATH%
and then run
java DerbyPreparedStatement
(this assumes that DerbyPreparedStatement.class is in your current directory).
thanks,

That's pretty much always a CLASSPATH issue.
From the same window where you get the ClassNotFoundException,
try running org.apache.derby.tools.sysinfo, and paste the output
into an email reply so we can see it.
If sysinfo also gives you a ClassNotFoundException, then:
$ echo $CLASSPATH
and do 'ls' on each item in the classpath to confirm that each exists.
