You can also create a new Tomcat server from the explorer using the Add button and run a war package on it. You can also create the server during the deployment. For running and debugging a package, you can right-click a server to select a war package to debug. More details could be found in the GitHub repository of the Tomcat extension.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to GitHub data from a connection pool in Tomcat.
Github Tomcat Server.xml
Connect to GitHub Data through a Connection Pool in Tomcat
- 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.
- Add a definition of the resource to the context. Specify the JDBC URL here.
GitHub uses the OAuth 2 authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Getting Started chapter of the CData help documentation for an authentication guide.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the GitHub JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.github.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/github' auth='Container' type='javax.sql.DataSource' driverClassName='cdata.jdbc.github.GitHubDriver' factory='org.apache.tomcat.jdbc.pool.DataSourceFactory' url='jdbc:github:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;InitiateOAuth=GETANDREFRESH' maxActive='20' maxIdle='10' maxWait='-1' />
To allow a single application to access GitHub 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 GitHub for all applications.
- Add a reference to the resource to the web.xml for the application.
GitHub data JSP jdbc/GitHub javax.sql.DataSource Container
- Initialize connections from the connection pool:
Context initContext = new InitialContext();Context envContext = (Context)initContext.lookup('java:/comp/env');DataSource ds = (DataSource)envContext.lookup('jdbc/GitHub');Connection conn = ds.getConnection();

The steps above show how to connect to GitHub data in a simple connection pooling scenario. For more use cases and information, see the JNDI Datasource How-To in the Tomcat documentation.
