ClassPath and still NoClassDefFound

Question

To copy files from one directory to another, I've written a small program that uses the Apache Commons package. Since it is an external package, I include the classpath when compiling, and it works fine:
javac -classpath /Apache_classpath_dir/commons-io-1.3.1.jar GetFiles.javaWhen running the program, however, things don't go that well
java -classpath /Apache_classpath_dir/commons-io-1.3.1.jar GetFileswhich results in: java.lang.NoClassDefFoundError: GetFiles
Since that didn't work, I tried running the program without the classpath option:
java  GetFilesbut this failed with the message: java.lang.NoClassDefFoundError: /org/apache/io/FileUtils
To me it seems like I have to put my own program in the same directory as where the jar file from Apache is, which seems unlikely. Any suggestions?

Answer 1

java -classpath /Apache_classpath_dir/commons-io-1.3.1.jar GetFiles
which results in: java.lang.NoClassDefFoundError:
GetFiles
...You will probably have to include the current working directory to the classpath as well when running your class file.
Try this:java -classpath .;/Apache_classpath_dir/commons-io-1.3.1.jar GetFiles

                +--- periodnote that the period represents your current directory (where GetFiles resides) and the semi-colon is a dividor between classpaths.
Good luck.
