Configuration Steps
1) Copy the JDBC driver appropriate for your database into <frevvo-home>\tomcat\webapps\database\WEB-INF\lib
...
| Code Block |
|---|
<Parameter name="frevvo.connectors.database.configuration" value="c:/frevvo/dbconfig/configuration.xml" override="false"/> |
Be sure to add it OUTSIDE of the manager tags in the file. Also, verify that your path to the configuration file is correct. Here is an example of how the file should look after editing:
| Code Block |
|---|
<Context swallowOutput="true" unloadDelay="40000"> <Manager className="org.apache.catalina.session.PersistentManager" saveOnRestart="false"> <Store className="org.apache.catalina.session.FileStore"/> </Manager> <Parameter name="frevvo.connectors.database.configuration" value="C:/frevvo/dbconfig/configuration.xml" override="false"/> </Context> |
| Note |
|---|
If is running, when you edit and save this change to context.xml.default, should pickup this change within a couple seconds. If it doesn't, then stop and restart by: Double click <frevvo-home>\stop-frevvo. Wait for it to stop. Then double click <frevvo-home>\start-frevvo Currently you MUST restart after moving the configuration file location. If you don't restart the connector will return a blank page rather than data and the frevvo- tomcat log will show an NPE error. |
...
| Code Block |
|---|
<resource-def>
<url>YOUR database Url HERE</url>
<driver>YOUR driver HERE</driver>
<user>YOUR database user HERE</user>
<password>YOUR password HERE</password>
</resource-def> |
The <resource-def> defines the database connection inside the database connector itself.
| Note |
|---|
Under most operating systems the database connector will automatically reload the configuration.xml as soon as you edit and save changes, without the need to restart tomcat or the database connector itself. However under Mac OS auto reload does not work. To ensure that the change is reflected restart tomcat manually via the stop/start scripts. |
Configuring a <resource-ref>
There is an alternate approach that defines the database connection in the application container (Tomcat if you are using the frevvo-tomcat bundle) instead of inside the database connector. To use this approach:
- Edit <frevvo-home>\tomcat\conf\Catalina\localhost\context.xml.default.
- Define a <resource> as shown below.
- Replace the <resource-def> element shown above in configuration.xml with a <resource-ref> element as shown below.
The XML samples below assume a MySql database driver. You will need to replace this sample values to match your database type.
This is the format of the <resource> element in context.xml.default.
| Code Block |
|---|
<Resource name="jdbc/mystore_ds"
auth="Container"
factory="org.apache.commons.dbcp.BasicDataSourceFactory"
driverClassName="com.mysql.jdbc.Driver"
username="YOUR database user HERE"
password="YOUR database password HERE"
type="javax.sql.DataSource"
url="jdbc:mysql://localhost/mystore?autoconnect=true"/> |
This is the format of the <resource-ref> element in configuration.xml.
| Code Block |
|---|
<resource-ref>
<description>MySQL Customers</description>
<res-ref-name>jdbc/mystore_ds</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref> |
mySQL example
A mySql database named "test" running on localhost on the default port when the login for user "root" requires no password:
...
| Code Block |
|---|
<resource-def>
<url>jdbc:as400://170.254.98.250:8888;date separator=-</url>
<driver>com.ibm.as400.access.AS400JDBCDriver</driver>
<user>yourUser</user>
<password>yourPassword</password>
</resource-def> |
Oracle 11g
Here is an example that connects to an Oracle 11g driver.
| Code Block |
|---|
<resource-def>
<url>jdbc:oracle:thin:@localhost:1521:ServiceName</url>
<driver>oracle.jdbc.driver.OracleDriver</driver>
<user>yourUser</user>
<password>yourPassword</password>
<validationQuery>select 1 from dual</validationQuery>
<resource-def> |
