[jboss-user] [JNDI and Naming] - What is the exact correct way to make JBoss datasource JNDI
Hi All,
I saw many people got confused of configuring DataSource JNDI on JBoss, I saw two major
example, but for me only one works.
I use Spring 2.5.6, Jboss 4.2.2GA, Sun JDK 1.5
Example 1:(works)
mysql-ds.xml
<?xml version="1.0"?>
| <datasources>
| <local-tx-datasource>
| <jndi-name>jdbc/esoafds</jndi-name>
|
<connection-url>jdbc:mysql://192.168.1.2:3306/jbranch?useUnicode=true&characterEncoding=UTF8&autoReconnect=true</connection-url>
| <driver-class>com.mysql.jdbc.Driver</driver-class>
| <user-name>root</user-name>
| <password></password>
| <min-pool-size>3</min-pool-size>
| <max-pool-size>100</max-pool-size>
| <use-java-context>false</use-java-context>
| <metadata>
| <type-mapping>mySQL</type-mapping>
| </metadata>
| </local-tx-datasource>
| </datasources>
Spring applicationContext.xml
<jee:jndi-lookup id="dataSource" jndi-name="jdbc/esoafds"
resource-ref="false" />
Above example, could someone advises me why I have to add
<use-java-context>false</use-java-context> to make this config works?
Example 2:(It should work, but NOT)
mysql-ds.xml
<?xml version="1.0"?>
| <datasources>
| <local-tx-datasource>
| <jndi-name>jdbc/esoafds</jndi-name>
|
<connection-url>jdbc:mysql://192.168.1.2:3306/jbranch?useUnicode=true&characterEncoding=UTF8&autoReconnect=true</connection-url>
| <driver-class>com.mysql.jdbc.Driver</driver-class>
| <user-name>root</user-name>
| <password></password>
| <min-pool-size>3</min-pool-size>
| <max-pool-size>100</max-pool-size>
| <metadata>
| <type-mapping>mySQL</type-mapping>
| </metadata>
| </local-tx-datasource>
| </datasources>
Please be aware that no "use-java-context" tag needed.
web.xml
<resource-ref>
| <description>Esoaf DataSource</description>
| <res-ref-name>jdbc/esoafds</res-ref-name>
| <res-type>javax.sql.DataSource</res-type>
| <res-auth>Container</res-auth>
| </resource-ref>
jboss-web.xml
<jboss-web>
|
| <resource-ref>
| <res-ref-name>jdbc/esoafds</res-ref-name>
| <jndi-name>java:jdbc/esoafds</jndi-name>
| </resource-ref>
|
| </jboss-web>
Spring applicationContext.xml
<bean id="dataSource"
class="org.springframework.jndi.JndiObjectFactoryBean">
| <property name="jndiName" value="java:jdbc/esoafds"/>
| </bean>
Should I add "java:" before "jdbc/esoafds" or not?
The second example can find correct JNDI name from JBoss, but it returns null from JNDI
look up.
Can any body give me a hint what's the concept difference between the two approaches?
Why my example 1 works, but exmple 2 return null look up.
Thanks a lot.
