code is written, imperceptibly, and his martial arts can be improved.If I have a good teacher around me, follow him, watch him programming, improve how fast ah.While learning Java SE and Java EE, I will read the source code:Java Collection Source code in JDK: The ancestor's thing absolutely classicJUnit Source code: See how Eric Gamma and Kent Beck create systems through patterns (reply to "JUnit" view)Springside: The spring framework-centric, pragmatic-style Java EE Application Reference examp

I. Overview of the SMACK LibrarySmack is an open-source, easy-to-use Xmpp/jabber client library that is developed in the Java language and developed by Jive Software.The advantage of smack is that programming is simple.Smack's disadvantage is that its API is not designed for a large number of concurrent users, each customer needs 1 threads, occupy a relatively high resource, so when using smack for simulation testing, 1 machines can only simulate a li

system runs, it borrows one from the pool of objects that have been generated, so that there is no need to do new at the time of use, saving overhead, Improves performance, so a truly mature performance solution requires support for object pooling.In a purely web-structured system (that is, it can only run in a tomat environment), such as Struts + hibernate, and so on, unless you do it yourself, generally there is no object pool technical support, so their performance can only be considered dem

now complete.If you are careful, you will find that the call above is similar to the one we read from the file: New filereader (filename); New BufferedReader (FR);In fact, Java I/O API is implemented using decorator, I/O variants are many, if all take the inheritance method, will produce many subclasses, obviously quite cumbersome.Implementation of decorator in JiveIn the forum system, some special words can not appear in the forum such as "Down xxx", we need to filter these "reactionary

Disadvantage: The API is not designed for a large number of concurrent users, each customer wants 1 threads, occupies a large resource, 1 machines can only simulate a limited (thousands of) customer.

solved. The doc document is the answer, as in the question of how some classes/methods are used. For some knowledge point of doubt is, write code test, will give you a deep impression. And some problems, you may need to look directly at the API source code to verify your ideas. It is a last resort to consult others. 3.2.3 Learning the design idea of open source software The Java domain has a number of open-source tools, components, frameworks, JUnit, ANT, Tomcat, Struts, Spring,

The user access control mechanism is always discussed in terms of coarse-grained and fine-grained two aspects: Coarse-grained control: You can provide access to a layer of an entire object or group of objects, while fine-grained control is always controlled at the method or property layer, such as: Allowing a file to be read-only is coarse-grained control, and allowing write operations on a particular line of the file is fine-grained. A good user control mechanism, of course, allows fine-grai

openfire SVN + Eclipse 3.3 + Subversive Installation Guide OpenFire is the Jive Software led the development of a very powerful open source IM Server (formerly known as Wildfire), which is based on the XMPP protocol, fully implemented in Java, is a very good server-side software.

Why factory patterns are so common. Beca

The connection pool was removed directly from the jive and modified to allow the connection parameters to be read directly in the program rather than in the subordinate file. Usage: First set your own connection parameters, in the Dbconnectiondefaultpool.java file Loadproperties method. Note that you also need to set the location of the log file for the connection pool. String driver= "Org.gjt.mm.mysql.Driver";//This is the JDBC driver used String

Yesterday I tried to say what I thought about the factory method. Today, the abstract factory. In yesterday's post, for a factory class, we just defined a createproduct (), similar, we can also define CREATEPRODUCT1 () in the Factory, CreateProduct2 () A series of methods to create a product line related to this factory. An example is a BBS access to the design. You can use the factory method to design a unified access interface for the Permissions section. You can refer to the Java Open Source
