Cargo adds support for multiple data sources

Recently I've been working on getting the Selenium tests for the Apache Continuum project working again. Continuum is normally packaged in a Jetty bundle with everything it needs, but in order to automate the tests, I need to deploy just the webapp into a standard servlet container.

For a long time, Cargo only supported a single data source, so it wasn't possible to configure the Cargo Maven plugin to add the three data sources that Continuum needs -- two databases, for users and builds, plus one for sending email.

That changed recently, but when I tested out the new support for multiple data sources, I ran into a problem with the JNDI mail session. Just mentioning that on the Cargo dev list resulted in a quick fix.

It hasn't been released yet, but using the latest snapshot built from trunk, multiple data sources can be configured for the Cargo Maven plugin as follows:

     <plugin>
       <groupId>org.codehaus.cargo</groupId>
       <artifactId>cargo-maven2-plugin</artifactId>
       <version>1.0-SNAPSHOT</version>
       <configuration>
       ...
         <configuration>
           <home>${project.build.directory}/tomcat5x</home>
           <type>standalone</type>
           <properties>
             <cargo.servlet.port>9595</cargo.servlet.port>
             <cargo.datasource.datasource.users>
               cargo.datasource.driver=org.apache.derby.jdbc.EmbeddedDriver|
               cargo.datasource.url=jdbc:derby:${project.build.directory}/databases/${container.name}/users;create=true|
               cargo.datasource.jndi=jdbc/users|
               cargo.datasource.username=sa
             </cargo.datasource.datasource.users>
             <cargo.datasource.datasource.builds>
               cargo.datasource.driver=org.apache.derby.jdbc.EmbeddedDriver|
               cargo.datasource.url=jdbc:derby:${project.build.directory}/databases/${container.name}/builds;create=true|
               cargo.datasource.jndi=jdbc/continuum|
               cargo.datasource.username=sa
             </cargo.datasource.datasource.builds>
             <cargo.resource.resource.mail>
               cargo.resource.name=mail/Session|
               cargo.resource.type=javax.mail.Session|
               cargo.resource.factory=org.apache.naming.factory.MailSessionFactory|
               cargo.resource.parameters=mail.smtp.host=localhost
             </cargo.resource.resource.mail>
           </properties>
      ...

You can see a full example in the continuum-webapp-test module's pom.xml file:
