1. Edit <tomcat-install>/conf/context.xml. 

    

2. Within the Context tags, insert the DataSource Resource tag:

    

   Code Block
   language xml
   <Resource name="jdbc/TermWebDS" auth="Container" type="javax.sql.DataSource" username="termwebuser" password="termwebpwd" driverClassName="org.postgresql.Driver" url="jdbc:postgresql://localhost/termweb" maxActive="20" maxIdle="10" validationQuery="Select 1"/>

   1. • If PostgreSQL does not run on the same server as Tomcat, replace localhost in url with the name of the database server
      • If you named the database something else than termwebdb, replace termwebdb in url with your database name 
      • Replace termwebuser and termwebpwd in url with your database user and password.

   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.
     • maxActive – The maximum number of active instances 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.
     • 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.
     • 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.

    

 Congratulations, you now have TermWeb connected to your PostgreSQL database.
