Generally speaking, the formation of the current Java-EE enterprise development efficiency is low because of a few: the division of meticulous, technical line long, customers can not participate in the development of the complexity of too high. These aspects of the factors between cause and effect, interaction, and finally the entire development process dragged into the mire. The following is discussed in detail. 5.1 Division of Labor meticulous T

Example of a simple application of regular expressions in central view [java-based] This article describes the simple application of regular expressions in central view. We will share this with you for your reference. The details are as follows: Because the development work needs to filter the content in the text, delete or replace some useless or non-conforming

Java build tool-ant Application Guide (3) Call ant in your own program Ant's task is actually a piece of functional code. A large number of built-in tasks of ant are of great significance for developing Java applications. Why cannot we use them directly? Although it is not complicated to call ant tasks in a program, we know that ant tasks are actually

In recent times, our production system upgrade frequently failure, the specific failure phenomenon is 10 minutes after the start of the transaction slow, processing thread exhaustion and so on, and the frequency of the failure occurs quite high. After detailed diagnosis and troubleshooting, we finally found the problem, which is that groovy runs in OSGi with ClassLoader deadlock, and finally we solve the problem.If it is difficult to find this problem by looking at the code alone, in this troubl

Now, what GUI do you use to develop the most and hottest applications in Java? andorid! No one should know! Do you know of AWT, Swing, SWT, and JavaFX? Although they are primarily used to develop desktop applications, it is not entirely true, and JavaFX can be exported as a mobile app. Whatever, no matter what platform they face, they are Java-based GUI toolkit or framework, as the technology development, t

Recent work has encountered a problem like this:Do a test tool for all the interfaces in a project, using Java Swing technology, the project has different versions, not all versions of the interfaces are the same, and the tools I do need to be compatible with all versions.So the question was introduced:Some interfaces do not exist in the partial version, then the interface to perform this operation will be

This chapter is a brief statement In the previous chapter, the author has explained several knowledge points used in the WinForm development process. The author can take this as the beginning to study. In this chapter, we are talking about a point of knowledge related to ORM thought. Before we talk, let's think about the hibernate knowledge point of Java. Hibernate is also an ORM framework. Remember that there is a name hql in Hibernate. Fi

, or quite new ah.Before entering the code, let's take a look at the roles that the next three frameworks play.1 Struts: Why do we use struts to compare with a servlet? In fact, we can still do MVC without struts, but it may be more depressing on the configuration file. Struts primarily helps us implement a function of distribution, struts1 our specific requests into a specific class, and helps us to set the properties. X is done by Actionform). Struts2 is much more advanced than struts1, automa
