If you using this lib org.apache.commons.logging.LogFactory then you should probably initialize log according to classes @ coding
Example
private static Log LOG = LogFactory.getLog(ClassName.class);
It has .class extension when compile you should make sure whether that class created or not else it will give an exception, i guess
Check the classpath too
Issue-java.lang.NoClassDefFoundError
Root Cause: Incorrect Java path set in Environment Variable Section
Solution: Set correct JAVA_HOME Path
Steps->Environment Variable Setting (My Comp-Right Click ->Properties->Env Variable->Advance Tab ->Variable)
Create new JAVA_HOME Environment Variable.
JAVA_HOME .;C:Program Files (x86)Javajdk1.6.0_14
Set JAVA_HOME variable in PATH Variable section.
PATH %JAVA_HOME%bin
Set JAVA_HOME variable in CLASSPATH Variable
CLASSPATH %JAVA_HOME%jrelib
Restart System
Verify all variable
echo %CLASSPATH%
echo %JAVA_HOME%
echo %PATH%
Compile & Run the program
