What bin/ directory? Surely not the bin/ directory of the Java installation?

Java source and output should go in some sort of project directory, for
example, "%HOME%/projects/" (Windows envar style). Let's say your project
"foo" is in there:

%HOME%/project/foo/src/

would be the root of your source tree, and

%HOME%/project/foo/build/classes/

the root of your class output tree, and thus your runtime class path. For an
application (a Java class with a main()), you'd invoke it like this:

java -cp %HOME%/project/foo/build/classes/ example.packg.foo.Primary

You would have compiled it like this:

cd %HOME%/project/foo/src/
javac \
  -cp %HOME%/project/foo/build/classes/;%JAVA_JARS%/log4j-1.2.14.jar \
  -d %HOME%/project/foo/build/classes/ \
  example/packg/foo/Primary.java

(ignoring the linewrap)
