 "Starting Sample Axis2 Server ..."
 Using AXIS2_HOME:      D:\axis2
 Using JAVA_HOME:       C:\Program Files\Java\jdk1.6.0_33
 Server could not start due to class loading issue java.lang.ClassNotFoundException: samples.util.SampleAxis2Server

Answer 1

Have you defined AXIS2_HOME environment variable ? If so remove that and try. You can see that

Using AXIS2_HOME:      D:\axis2 

is not using some other server. (I tried to start server in windows and started successfully.)
