Configure the CData JDBC Driver for Basecamp in a Connection Pool in Tomcat

Connect to Basecamp data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Basecamp data from a connection pool in Tomcat.

Connect to Basecamp Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    Basecamp uses basic or OAuth 2.0 authentication. To use basic authentication you will need the user and password that you use for logging in to Basecamp. To authenticate to Basecamp via OAuth 2.0, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties by registering an app with Basecamp.

    See the Getting Started section in the help documentation for a connection guide.

    Additionally, you will need to specify the AccountId connection property. This can be copied from the URL after you log in.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Basecamp JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.basecamp.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/basecamp" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.basecamp.BasecampDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:basecamp:User=test@northwind.db;Password=test123;" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Basecamp data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Basecamp for all applications.

  3. Add a reference to the resource to the web.xml for the application. Basecamp data JSP jdbc/Basecamp javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/Basecamp"); Connection conn = ds.getConnection();
