AlertHandler.java

client.java

Compiler.bat code

javac -d bin -sourcepath src/*.java src/sign/*.java

.classpath file

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7"/>

In order to compile your project you have to

1. create a text file listing all your java files. For example, compile-list.txt :

    src/MyClass1.java src/mypackage/MyClass2.java ... 

2. Run javac specifying source and target version and the file with your classes:

    javac -source 1.7 -target 1.7 -d bin @compile-list.txt 

Specifying -sourcepath src would allow javac to resolve unlisted (forgotten) classes from the source directory, in case they are needed.

Since this is extremely unhandy process I would recomment to use Ant or Maven .
