24 Oct 2010 ... Tested: Java midlet QR code readers. QR Code readers are as easy as pie on smartphones such as the iPhone and Android-based phones. The ZXing barcode app for those platforms does a great job of decoding almost everything you can throw at it. As this code shows, you can use @javax.persistence.Version on a persistence field or property. The persistence field should be a numeric field of type long, Long, int, or Integer, and it should be mapped to a database column on the primary table to which the entity is mapped. In our example, the version property is mapped to the OPT_LOCK column. You may see some resistance from your DBA to adding an extra column to store the version, but you will have to persuade her that you need this column to support optimistic locking in your applications. Applications cannot set the version attribute, as it is used directly by the persistence provider. The version column is automatically incremented when the persistence provider commits changes to the database. When you merge an entity instance to a persistence context, the persistence provider will check the version column to ensure that the detached entity has not become stale. If you are using TopLink Essentials, you can enable logging to see SQL statements when a detached entity instance is merged as follows: qr code scanner java source code BeeTagg QR Reader for Java (en)

Dedicated syntax Method pointcut XML tags with XML with Perl 5 regular with GNU regular java.util.regexp expressions expression expressions Advice code proceed Wrapper proceed Interceptor invokeNext Interceptor proceed In this code, the persistence provider is incrementing the value for the version attribute (ITEMS.OPT_LOCK) and updating the ITEMS table with the new value in the OPT_LOCK column. The WHERE clause includes the OPT_LOCK column and compares it with the old value. If the WHERE clause fails, then the persistence provider will throw an OptimisticLockException. Some persistence providers may choose to support additional mechanisms to check optimistic locking and, depending on their implementation, may render your applications less portable. environment variables 134 equality 23 equals 23 EquityBean 7, 24, 81, 137 sample toString 137 with a database view 115 EquityHome 6 equityPriceView 115 EquityVO 125 error handling message-driven beans 221 rollbacks in a message-driven bean 225 ErrorHandler 223 executing test cases 274 using a UI 298 executing unit tests from a web browser 298 from UI classes 299 13.1.3 EntityManager and lock modes Although you will very rarely need it, the EntityManager provides a lock method to explicitly acquire a lock on an entity: // begin transaction... entityManager.lock(item, LockModeType.READ); ...
