Hibernate Related JAR Package description

Hibernate-related jar packages are described in more detail below:

1.Hibernate3.jar (Hibernate's core library, the jar that must be used)

2.Cglib-asm.jar (cglib library, Hibernate uses it to achieve the dynamic generation of PO bytecode, very core libraries, the jar that must be used)

3.Dom4j.jar (dom4j is a Java XML API, similar to Jdom, used to read and write XML files, which is necessary jar,hibernate use it to read and write configuration files, the jar that must be used)

4.Odmg.jar (ODMG is an ORM specification, Hibernate implements the ODMG specification, which is a core library that must be used by the jar)

5.Commons-collections.jar (one of the Apache Commons packages, contains some of the Apache-developed collection classes, features that are more powerful than java.utils.* and must be used by the jar)

6.Commons-beanutils.jar (one of the Apache Commons packages that contains some bean tool classes that must be used by the jar)

7.Commons-lang.jar (one of the Apache Commons packages, containing some data type tool classes, is the extension of the java.lang.*, the jar that must be used)

8.Commons-logging.jar (one of the Apache Commons packages that contains the log function , the jar that must be used. The package itself contains a simple Logger, but the function is very weak. Used with log4j. However, it is strongly recommended to use log4j because of the high performance of log4j. )

These are the jar packages that hibernate must have, and the rest are optional packages

Ant.jar (ant compilation tool jar package, used to compile Hibernate source code, if you are not ready to modify and edit Hibernate source code, it is not useful, optional jar package)

Optional.jar (one of Ant's Auxiliary packages)

C3p0.jar (C3P0 is a database connection pool, hibernate can be configured to use C3P0 connection pool, if you are ready to use this connection pool, you need this jar package)

Proxool.jar (also a connection pool, using the same principle)

Commons-pool.jar Commons-dbcp.jar (DBCP database connection pool, emphasize that if you use Hibernate in EJBs, be sure to use the App server connection pool, do not use the above four connection pools, or the container management transaction does not work)

Connector.jar (JCA specification, if you configure Hibernate to connector on the app server, you need this jar, but in fact the General app server comes with this package, so it's actually an extra package)

Jaas.jar: (Jaas is used for permission validation and is already included in the JDK1.4.) So it's actually an extra bag. ）

Jcs.jar: (If you're going to use JCS in Hibernate, you have to include it, otherwise you don't.) ）

Jdbc2_0-stdext.jar: (JDBC2.0 expansion pack, generally the database connection pool will use it.) But the app server is always on, so it's redundant. ）

Jta.jar: (JTA Specification, when hibernate use JTA, but the app server will be brought, so it is redundant.) ）

Junit.jar: (JUnit packages are required when you run Hibernate's own test code, otherwise you don't.) ）

Xalan.jar, Xerces.jar, Xml-apis.jar:

(Xerces is an XML parser, Xalan is a formatter, Xml-apis is actually JAXP.) General app Server will bring, JDK1.4 also contains the parser, but not xerces, is crimson, inefficient, but hibernate with XML is just read configuration file, performance is not critical, so is redundant. ）
