My Entity: .... @Column(name = "USERNAME", length = 16, nullable = false, unique = true) private String username; @UserPrincipal public String getUsername() { return username; } With this code above i get this Error: Caused by: java.lang.IllegalAccessException: Class org.jboss.seam.util.Reflections can not access a member of class ch.pomop.dummy.security.UserAccount with modifiers "private" at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65) at java.lang.reflect.Field.doSecurityCheck(Field.java:954) at java.lang.reflect.Field.getFieldAccessor(Field.java:895) at java.lang.reflect.Field.get(Field.java:357) at org.jboss.seam.util.Reflections.get(Reflections.java:51) at org.jboss.seam.util.Reflections.getAndWrap(Reflections.java:88) ... 83 more Is it necessary to set the members public? or is this a bug? As i changed the my Entity Code to: My Entity: @UserPrincipal @Column(name = "USERNAME", length = 16, nullable = false, unique = true) public String username; } it worked but I don't want to set my members public if there is an other way thx for help
