Something I did not make clear. That idea of adding
the current directory to the class path only works when
you are 'inside' the directory with the .class file.

If you're .java and .class is located..

C:\javatest\projectA\> dir
TestRun.java
TextRun.class

..then you need to put a .bat file in the directory..

'runTheProject.bat' containing the single line..

java -cp . TestRun

So your directory may now look like..

C:\javatest\projectA\> dir
TestRun.java
TextRun.class
runTheProject.bat

If you double click 'runTheProject.bat'
the diectory 'C:\javatest\projectA\'
will be added to the classpath and
'C:\javatest\projectA\TestRun.class'
will be visible to Java..
