Introduction: Learn how to migrate Hibernate application source code, Object Relational mappings, and configuration parameters to OpenJPA by using the equivalent functionality in EJB 2.1 and OpenJPA and EJB 3.0 to compare features and functionality in Hibernate applications.
Introduction
Hibernate is an open source persistence and query framework that provides object-related mappings of traditional Java™ objects (POJO) to relational database tables,

Summary: View clickonce technology, compare it with other deployment technologies, and demonstrate how to use this technology in applications.
Introduction
Clickonce is a new windows form deployment technology included in Visual Studio 2005. This technology uses a smart client to simplify the installation and upgrade of Web applications. Since the first version
Http://www.adobe.com/cn/devnet/air/articles/considerations-air-apps-mobile.htmlAdobe AIR has evolved beyond the initial goal of being a desktop application platform. Today, it supports standalone application development across mobile, desktop, and digital home devices. AIR is an attractive development platform, in part because of its wide coverage. At the same time, each of these environments offers unique requirements for mobile application development and design.Mobile
You can find instructions on how to install and use terminal services on the Internet and in local bookstores. However, most of them provide users with unknown benefits for remote applications. With only a few operations, you can quickly deploy a terminal server that hosts the required applications in your environment. However, to meet user expectations, you must consider other situations.

various underlying transaction management techniques, such as jta or JDBC transaction provides a consistent programming model. spring provides a AOP framework, which is written in the standard Java language, which gives pojos provides declarative transaction management and other enterprise transactions-if you need-you can also implement your own aspects . This framework is powerful enough to allow applications to throw away the complexity of EJB

As with other APIs, you can use the Sockets API in a number of ways to improve the performance of the socket or to limit the performance of the socket. This article explores 4 ways to use the Sockets API to get the maximum performanc
In the previous article, "Using Golang to design our Ubuntu scope," We've covered how to use Golang to develop Ubuntu scope. In today's article, let's take a brief look at how to use Golang to develop QML applications. This is a good choice for some of the familiar Golang languages, but not very familiar with C + + development. While most of our QML applications require only QML with some JavaScript scripts
Win8.1 Systems bring a number of practical applications, such as mail, calendar and networking applications, to make our social and daily life more convenient and comfortable. How do we upgrade email, calendar, and networking apps for Win8.1 systems by updating email, calendar, and networking apps?

With the development of the Internet, the complexity of Web applications has been improving, and a single Web application has been unable to meet complex business requirements. For example, Baidu's search, news, encyclopedia, bar Paste, in fact, are different sites. When users use these platforms, we certainly do not want users to have a separate account on each platform, otherwise users and developers may be tempted to cry. So we need a system where
The deployment of Java EE applications is a significant thing for the deployer. Existing application servers generally support the deployment of applications based on the Web, or hot deployment, or through the deployment of tools. WebSphere Application Server 5.x provides an application programming interface for deployment and management of Java EE applications.
When the CPU enters the multi-core era, the performance tuning of the software is no longer a simple matter. Programs that do not have parallelization may run more slowly on new hardware than before. When the number of CPUs increases, it is wise for the chip manufacturer to reduce the frequency of CPU running in order to achieve the best performance/power ratio. Using Java to write multithreaded applications has been a lot simpler than C + + programme
Users always want to install more Windows applications, but if administrators really give users local administrative rights, then the network may face serious threats, and the more dangerous the user installs the application, the more complex the network security effort is. Therefore, when the administrator gives the user local authority, should adopt some tactics, lest to cause the security risk to the network.
Network security expert Brad Casey has
In this article, you will introduce some ways and techniques to improve the performance of ASP.net Web applications. As we all know, solving performance problems is a tedious task, and when performance problems occur, everyone blames developers who write code.
So how is the performance problem to be solved? The following are the points that the. NET developer needs to check before the application system is released.

When using a JDBC transaction definition, you can combine multiple SQL statements into a single transaction. One drawback of JDBC transactions is that the scope of the transaction is limited to one database connection. A JDBC transaction cannot span multiple databases.
