To be rewritten
Rewrite like SQL Server connection page
1. Shut down Tomcat
- Run
bin/shutdown.sh
orbin/shutdown.bat
to bring Tomcat down while you are making these changes. - Make a backup of your
server.xml
andcontext.xml
files in<tomcat-install>/conf/
so that you can easily revert if you have a problem.
2. Install the Drivers
- Download the MySQL Connector/J JDBC driver from http://dev.mysql.com/downloads/connector/j/
- After unpacking the file you have downloaded, you will find a file called something like
mysql-connector-java-5.1.22-bin.jar
. - If you are running Tomcat 6.x or Tomcat 7.x, copy the file into
<tomcat-install>/lib.
On Tomcat 5.5, copy this file into thecommon/lib
directory of your Tomcat installation.
3. Create database
Create the TermWeb database by opening a DOS prompt and enter the following:
mysql -u root -p < createdb.sql
This creates an empty database called termweb and a user termwebuser with password termwebpwd. The user name and password can be changed as desired. The user currently needs all permissions (except GRANT) in the database.
Import the
termweb.sql
file to the database, by running the following at the DOS prompt:mysql -u termwebuser -p termwebpwd termweb < termweb.sql
The database is now set up.
4. Configure Tomcat
For Tomcat 6.x and Tomcat 7.x, edit
<tomcat-install>/conf/context.xml
.
If you are running Tomcat 5.5 you edit<tomcat-install>/conf/server.xml
.Within the
Context
tags, insert the DataSourceResource
tag:<Resource name="jdbc/TermWebDS"
auth="Container"
type="javax.sql.DataSource"
username="termwebuser"
password="termwebpassword"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/termweb?autoReconnect=true&
useUnicode=true&characterEncoding=utf8"
maxActive="20"
maxIdle="10"
validationQuery="Select 1"/>- Replace the username and password parameters with the correct values for your database.
- In the url parameter, replace the word 'termweb' with the name of the database your TermWeb data will be stored in.
The configuration properties for Tomcat's standard data source resource factory (
org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory
) are as follows:driverClassName
– Fully qualified Java class name of the JDBC driver to be used.maxTotal
– The maximum number of active connections that can be allocated from this pool at the same time.maxIdle
– The maximum number of connections that can sit idle in this pool at the same time.minIdle
– The minimum number of idle connections that will remain in this pool at the same time.maxWait
– The maximum number of milliseconds that the pool will wait (when there are no available connections) for a connection to be returned before throwing an exception.password
– Database password to be passed to our JDBC driver.url
– Connection URL to be passed to our JDBC driver. (For backwards compatibility, the property driverName is also recognized.)user
– Database username to be passed to our JDBC driver.- testWhileIdle – If the validity of the connection should be tested also when idle. Recommended to set this to
true
to avoid hanging connections. validationQuery
– SQL query that can be used by the pool to validate connections before they are returned to the application. If specified, this query must be an SQL SELECT statement that returns at least one row.
4. Restart Tomcat
Run bin/startup.sh
or bin/startup.bat
to start Tomcat and TermWeb with the new settings.
