This isn't actually a problem in Geany so much as it is a
misunderstanding about how Java packages work.
Check out this resource for help:

I facing some problems in running java.class files from geany, I am able
to successfully compile the the java source files .
Here is a simple example of what is happening :
I have a Source file named VowelsToUnderScores.java which resides under
the package(directory) called 'strings' . I have set the classpath for
both the Compilation and Execution in "Set Includes and Arguments"
dialog box and the commands in the dialog box goes like this:
-------------------------
Java source file commands
Compile : javac -classpath /home/siddharth/Programming/Java\
Files/oprt/opr/src "%f"
Execute : java -classpath /home/siddharth/Programming/Java\
Files/oprt/opr/src "%e"
----------------------
As I said the compilation was successful but when I run the compiled
file (F5) , I get get an error in the Run Window which shows the
following error messages :
----------------------------------
Exception in thread "main" java.lang.NoClassDefFoundError:

Could not find the main class: VowelsToUnderScores. Program will exit.

Here is the code written in VowelsToUnderScores.java file for your

Here's another bit of information which I accidentally found when
writing this mail - when I comment the package information and make the
Execute command in the Set Includes and Argument dialog look like this :
--------
Execute : java "%e"
----------
Then I am able to run the program successfully ! .
I want to be able to run the code with the package information intact .
Can any one here help me out ? .
Thank you for your help .
