java.lang.ClassNotFoundException: No ClassLoaders found
I try to call a class which is not in ejb-jar.xml using Class.forName() from whithin EJB session bean as below.
But it give me the ClassNotFoundException error.
Any idea to overcome this ???
try {
v = (PromoValidator) Class.forName("rpc.util.validators.Validator" + promoCode).newInstance();
}
catch (Exception e) {
System.out.println("=== PromoValidator for " + promoCode + " was not created");
e.printStackTrace();
}
