Connect to TigerGraph Data from a Connection Pool in Jetty

The CData JDBC driver for TigerGraph is easy to integrate with Java Web applications. This article shows how to efficiently connect to TigerGraph data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for TigerGraph in Jetty.

Configure the JDBC Driver for Salesforce as a JNDI Data Source

Follow the steps below to connect to Salesforce from Jetty.

1. Enable the JNDI module for your Jetty base. The following command enables JNDI from the command-line:

   java -jar ../start.jar --add-to-startd=jndi
2. Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.

3. Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the TigerGraph data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   <Configure id='tigergraphdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="tigergraphdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="tigergraphdemo"/></Arg> <Arg>jdbc/tigergraphdb</Arg> <Arg> <New class="cdata.jdbc.tigergraph.TigerGraphDriver"> <Set name="url">jdbc:tigergraph:</Set> <Set name="User">MyUserName</Set> <Set name="Password">MyPassword</Set> <Set name="URL">MyURL</Set> </New> </Arg> </New> </Configure>

   To authenticate with your TigerGraph instance, set the User, Password, and URL properties to valid TigerGraph credentials. By default connections are made on port 14240.

4. Configure the resource in the Web.xml:

   jdbc/tigergraphdb javax.sql.DataSource Container

5. You can then access TigerGraph with a lookup to java:comp/env/jdbc/tigergraphdb: InitialContext ctx = new InitialContext(); DataSource mytigergraph = (DataSource)ctx.lookup("java:comp/env/jdbc/tigergraphdb");
