http://www.onjava.com/pub/a/onjava/2004/02/25/25/Jbossjdbc.htmljboss 4.0 Developer Version is an open source application server, he puts HyperSonicDB as his default database. However, developers may also use a database other than HyperSonicDB, in which we will see how to configure other databases on JBoss. Introduction JBoss4.0 uses a JDBC profile to configure database connections, which provides data sources for EJBs and other J2EE applications. If you want to use the database other than HypersonicDB, you will modify this profile. This article will focus on the following sections: l JBoss EJB Deployment Descriptor L Oralce Database Configuration L MYSBASE Database Configuration L DB2 Database Configuration L infromix database configuration
JBoss's EJB deployment descriptor Standardjaws.xml (in x: / jboss4 / server / default / conf) is a standard deployment description file that maps CMP entity EJB. It is used to configure CMP entity EJB, you can also use jaws.xml instead. You can copy this file Copy to the meta-inf directory in the EJB .jar file. This file is used to describe the following information: l Describe a data source and mapping type. l Describe the EJB mapping table L Describes the Finder method L of EJB to describe the type map The data source described here is a JNDI name, which can obtain a data source connection pool by this JNDI. JBoss4 default data sources are HypersonicDB. If you need to use other data sources, you need to modify the jaws.xml file. Standardjbosscmp-jdbc.xml (in x: / jboss4 / server / default / conf) is a standard deployment description file configured for the JBoss CMP container, you can also use a custom profile -jbosscmp-jdbc.xml instead of it. This file is also placed in the meta-INF directory of the EJB.jar file. It is also a need to modify it by default or hypersonicDB as a database. Oracle Database Configuring Oracle has a very popular enterprise database with its operational stability and reliability. To configure Oracle on JBOSS, what is the first thing we have to do is to copy the Oracle's JDBC driver to ClassPath. We copied this JDBC driver to the server / default / lib directory. In order to use Oracle's transaction processing data source we must also copy /DOCS/examples/jca/oracle-xa-ds.xml to the / Server / Default / Deploy directory. If you use a non-transactional data source, copy the /DOCS/examples/jca/oracle-ds.xml file to the / Server / Default / Deploy directory. Next, we need to modify the Oracle-de.xml configuration file. one of them

Is the port of the Oracle database,

Next, modify StandardJbossCMP-JDBC.XML or JBossCMP-JDBC.XML configuration files, set

defaults>
jbosscmp-jdbc> Finally, we need to modify the login-config.xml file to use Oracle, below is login-config.xml file
element:
"Org.jboss.Resource.security.configuredIndityLoginmodule" Flag = "Required"> JBoss.jca: service = localtxcm, name = ORACLEDS MODULE-OPTION> login-module> authentication> Application-Policy> Modified Oracle-DS.xml, Standardjaws.xml, Standardjbosscmp-jdbc.xml, and After the login-config.xml file, you can use Oracle in jboss4. MySQL database configuration MySQL is an open source database, with many open source projects and small communities are using it. To use MySQL in JBoss4, first you want to put the mysql JDBC in the classpath. Similarly, copy it to the / server / default / lib directory, copy /DOCS/examples/jca/mysql-ds.xml to the / Server / Default / Deploy directory. Modify the mysql-ds.xml file, set For com.mysql.jdbc.driver Set as JDBC: mysql: // / ,among them Is the database host name It is the database name. Then you need to set Standardjaws.xml or Jaws.xml files. with element: jaws> It also needs to put the standardjbosscmp-jdbc.xml or jbosscmp-jdbc.xml file with The element is set to the following: defaults> jbosscmp-jdbc> Finally modify the login-config.xml file to use mysql: "Org.jboss.Resource.security.configuredIndityLoginmodule" Flag = "Required"> JBoss.jca: service = localtxcm, name = mysqlds MODULE-OPTION> login-module> authentication> application-policy> Modified mysql-ds.xml, standardjaws.xml, standardjbosscmp-jdbc.xml, and Login-config.xml files can be used on JBOSS using mysql. SYSBASE database configuration Sybase Adaptive Server Enterprises (ASE) is the Sysbase's database server. ASE can be used on UNIX and Linux platforms. Similarly, we have to drive its database to the classpath, copy it into the / server / default / lib directory, then copy the /DOCS/examples/jca/sybase-ds.xml to / Server / Default / Deploy directory . Modify the Sybase-DS.xml file Set to com.sybase.jdbc2.jdbc.sybdriver Set to JDBC: Sybase: TDS: : / ,among them The host name, port name, and database name, respectively. Also need to modify Standardjaws.xml or Jaws.xml files with element: jaws> modify the StandardJbossCMP-JDBC.XML or JBossCMP-JDBC.XML files and element: defaults> jbosscmp-jdbc> Finally modify the login-config.xml file to use the SYSBASE database. Set element: "Org.jboss.Resource.security.configuredIndityLoginmodule" Flag = "Required"> JBoss.jca: service = localtxcm, name = Sybaseds MODULE-OPTION> login-module> authentication> application-policy> Modified Sybase-DS.xml, Standardjaws.xml, Standardjbosscmp-jdbc.xml, and After the login-config.xml file, you can use Sysbase in JBOSS. DB2 database configuration IBM's DB2 is a perfect, easy to use the database server, which can be used on Linux, UNIX, and Windows platforms. Use DB2 on JBoss4 as long as you copy db2java.zip to the / Server / Default / Lib directory. Then copy the /DOCS/examples/jca/db2-ds.xml to / Server / Default / Deploy directory, then modify Element position com.ibm.db2.jdbc.app.db2driver, Element is JDBC: DB2: where Elements represent database service names. jaws> Here is the corresponding StandardJbosscmp-JDBC.XML (or JBossCMP-JDBC.XML) file: defaults> jbosscmp-jdbc> Finally, add the following content in the Login-Config.xml file: "Org.jboss.Resource.security.configuredIndityLoginmodule" Flag = "Required"> Principal> SA module-option> "Username"> SA module-option> "Password"> module-option> JBoss.jca: service = localtxcm, name = db2ds MODULE-OPTION> login-module> authentication> Application-Policy> You can use DB2 on JBOSS on JBOSS. Informix database configuration IBM's INFOXMIX database server is used as a data warehouse, analysis and reporting. Use the Informix database on JBoss4, first copy it to the / server / default / lib directory, then copy / serve / default / deploy In the directory, if you use a transaction (XA) JDBC, copy the /DOCS/examples/jca/informix-xa-ds.xml file. The next step is to modify this informix-ds.xml file, put The element is set to: com.informix.jdbc.ifxdriver Element is set to JDBC: Informix-Sqli: // : : InformixServer = , among them, , , Represents the database hostname, database port, and database service name, respectively. Then modify the StandardJaws.xml or Jaws.xml file with element: jaws> Put the standardjbosscmp-jdbc.xml or jbosscmp-jdbc.xml file with The element is set to the following: defaults> jbosscmp-jdbc> Added in the login-config.xml file element: "Org.jboss.Resource.security.configuredIndityLoginmodule" Flag = "Required"> JBoss.jca: service = localtxcm, name = informixds MODULE-OPTION> login-module> authentication> Application-Policy> You can use the Informix database in JBoss4. in conclusion JBoss4 uses the Hypersonic database by default, but if you see us as long as you have a simple modification of several configuration files, you can use the popular different databases on the market.
