Configure the CData JDBC Driver for Sugar CRM in 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 Sugar CRM data from a connection pool in Tomcat.

Connect to Sugar CRM 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.

   The User and Password properties, under the Authentication section, must be set to valid SugarCRM user credentials. This will use the default OAuth token created to allow client logins. OAuthClientId and OAuthClientSecret are required if you do not wish to use the default OAuth token.

   You can generate a new OAuth consumer key and consumer secret in Admin -> OAuth Keys. Set the OAuthClientId to the OAuth consumer key. Set the OAuthClientSecret to the consumer secret.

   Additionally, specify the URL to the SugarCRM account.

   Note that retrieving SugarCRM metadata can be expensive. It is advised that you store the metadata locally as described in the "Caching Metadata" chapter of the help documentation.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.sugarcrm.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/sugarcrm" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.sugarcrm.SugarCRMDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:sugarcrm:User=MyUser;Password=MyPassword;URL=MySugarCRMAccountURL;CacheMetadata=True;" maxActive="20" maxIdle="10" maxWait="-1" />

   To allow a single application to access Sugar CRM 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 Sugar CRM for all applications.

3. Add a reference to the resource to the web.xml for the application. Sugar CRM data JSP jdbc/SugarCRM 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/SugarCRM"); Connection conn = ds.getConnection();
