question: gets the value of the packageentry property . this accessor method returns a reference to the live list , not a snapshot . therefore any modification you make to the returned list will be present inside the jaxb object . this is why there is not a set method for the packageentry property . for example , to add a new item , do as follows : getpackageentry . add newitem ; objects of the following type s are allowed in the list packageentry concode_field_sep AccountInfo accountInfo concode_elem_sep String zipCode concode_elem_sep String country concode_elem_sep List<PackageEntry> packageEntry concode_elem_sep String salesScenario concode_elem_sep String orderId concode_elem_sep List<Fee> fee concode_elem_sep String language concode_elem_sep long serialVersionUID concode_elem_sep List<Notification> notification concode_elem_sep List<Charge> totalCharge concode_elem_sep List<Selection> selection concode_elem_sep String zipRequired concode_elem_sep String marketCode concode_elem_sep String orderLineId concode_elem_sep ModelProperties properties concode_elem_sep String locationIdentifier concode_field_sep void setCountry concode_elem_sep void setZipCode concode_elem_sep String getZipCode concode_elem_sep String getCountry concode_elem_sep void setOrderLineId concode_elem_sep void setProperties concode_elem_sep String getOrderId concode_elem_sep String getLocationIdentifier concode_elem_sep void setOrderId concode_elem_sep List<Notification> getNotification concode_elem_sep void setSalesScenario concode_elem_sep String getSalesScenario concode_elem_sep List<Fee> getFee concode_elem_sep String getOrderLineId concode_elem_sep String getLanguage concode_elem_sep List<Charge> getTotalCharge concode_elem_sep String getZipRequired concode_elem_sep ModelProperties getProperties concode_elem_sep void setLocationIdentifier concode_elem_sep void setZipRequired concode_elem_sep void setAccountInfo concode_elem_sep String getMarketCode concode_elem_sep List<Selection> getSelection concode_elem_sep AccountInfo getAccountInfo concode_elem_sep void setMarketCode concode_elem_sep void setLanguage
