Did you compile (javac) first?

[oll3i]

yes i did javac HelloClient.jav a HelloApp/*.java

[r035198x]

yes i did javac HelloClient.jav a HelloApp/*.java

Did it compile successfully? Also are you using the correct path when calling the java command?

it complies with 2 notes
note:HelloApp\H elloPOA.java uses unchecked or unsafe operations
note:Recompile with -Xlint:unchecked for details
