timestamp to track changes. The version number approach is preferred and quite reliable, because it could be that two users may be trying to update the same data at the same instant (timestamp). Every time a specific database row is updated, the version column is incremented by the application. When a user reads the entity, the version column is retrieved and stored with the entity instance. After making changes in the entity object, as the user tries to save the entity to the database, the application compares the version attribute of the entity object with that of the database. If the version attributes are the same, then the user is allowed to hold a write lock on the object, saves the object to the database, increments the version attribute, and then releases the write lock. If the version attributes are different, then it is assumed the entity has since been updated by someone else and the update is rejected with an OptimisticLockingException. If you re building an application with JDBC, then you ll have to implement a locking strategy yourself. However, if you re using the EJB 3 JPA, the persistence provider makes your life much simpler. The EJB 3 JPA persistence providers are required to support the optimistic locking strategy using a version number column in the database table. Let s take a closer look at how this is done. java barcode reader api Barcode Scanner implementation on Java - Stack Overflow

Java Barcode Reader is a Java library which scans and recognises barcodes from image files. You can embed barcode recognition features in your. If any of your entities are accessed concurrently in your applications, or detached entity instances are merged, then you must enable optimistic locking for those entities. For example, in the ActionBazaar application entities such as Item and Category are accessed concurrently. You must enable optimistic locking for these entities by adding a version attribute in these entities. java barcode reader example download Java Barcode API - DZone Java

There is ... in Java. ZBar, Reader library in C99. he previous chapters presented four of the most widely used tools for AOP: AspectJ, JAC, JBoss AOP, and Spring AOP. This chapter compares these four tools with regard to programming aspect-oriented applications. AspectJ, JAC, JBoss AOP, and Spring AOP each has its own techniques for implementing the concepts of AOP presented in 2. The three main concepts of AOP aspect, pointcut, and advice can be implemented with each of the four tools, but their forms as well as the means for programming them, such as syntax and API, vary. The terms used to describe these concepts may also vary among the tools; for example, the term advice is used by AspectJ, whereas JAC uses the term wrapper and JBoss AOP uses interceptor. Besides some minor conceptual and terminology differences, these tools can be classified into two types of approaches: the language approach (AspectJ) and the framework approach (JAC, JBoss, and Spring). These two types of approaches imply some important differences, which we ll cover in this chapter. Table 7-1 sums up and compares the features of AspectJ, JAC, JBoss AOP, and Spring AOP, which we ll cover in more detail throughout this chapter. The JPA specification does not mandate supporting optimistic locking without a version field on the entity. We can define a version attribute in the Entity item as follows: EJBLocalHome 23 EJBMetaData 25 27 EJBObject 19 ejbPassivate, inheriting 139 EJB-QL 68, 111 <ejb-ql> 114 <ejb-relation > 99 100 <ejb-relation-name> 99 ejbTimeout 146 147, 157, 160 ejbToString 136 137 EJBWebService 149 EJBWebServiceBean 150 @ejb.security-role-ref 64 email 144 asynchronous 223 synchronous 144 EmailBean 224 encapsulate business logic 210 encapsulating error-handling code in a message-driven EJB 221 Enterprise JavaBeans as a web service 149 building stubs 283 cascading deletes 104 CMP 81 compiling 278 creating a message-driven bean 202 disabling methods 235 email 223 error handling in an MDB 221 examining with reflection 25 faster lookup 31 finding client identity 231 finding client role 232 generating code 34 generating interfaces 37 handling rollbacks in an MDB 225 invoking another EJB (local) 4 invoking another EJB (remote) 6 logging in a cluster 263 logging with many clients 269 looking up with JNDI 43 one-to-many relationships 101 one-to-one relationships 97 packaging 280 @Entity @Table(name = "ITEMS") public class Item implements Serializable { @Id @Column(name = "ITEM_ID") protected Long itemId; ...
