Mysql Connection Pool in GlassFish 2.x.x

As a followup to a previous post, regarding the creation of an oracle connection pool in GlassFish 2.1.1, we will create a MySQL connection pool.

First of all, we need to download from www.mysql.com the latest jdbc driver:

http://dev.mysql.com/downloads/connector/j/5.1.html

Extract the downloaded archive and take the mysql-connector-java-x.x.x-bin.jar from the compressed archive and put in {glassfish}/lib directory and restart glassfish:

asadmin stop-domain domain1
asadmin start-domain domain1

Now we need to navigate to the administrator application:
http://localhost:4848/
 
Open the 'Resources' -> 'JDBC' -> 'Connection Pools' and select 'New.
Fill in the Connection Pool 'Name'.
Select 'Resource Type' : 'javax.sql.DataSource'.
Select 'Database Vendor' : 'MySQL'.
Select 'Next'.

At the next page go down at the additional Properties.
Find and edit the following properties :
Select 'Name' : 'User' and 'Value' : {db_user}
Select 'Name' : 'Password' and 'Value' : {db_user_pass}
Select 'Name' : 'URL' and 'Value' :
jdbc:mysql://[host]:[port]/[database name]
Select 'Finish'.

Navigate to Connection Pools and select the pool you just created.
Click Ping to test that it is working. If it is not, it is probably because you have mistyped the connection credentials. Go to 'Additional Properties' tab of the connection pool detail page and correct any errors. Try ping again.

Open the 'Resources' -> 'JDBC' -> 'JDBC Resources' and select 'New.
Fill the JNDI Name like 'jdbc/myconnnection'.
Select from 'Pool Name' combo box the pool we just created.
And select 'OK'.

The Connection Pool is ready!
