Connect to SharePoint Excel Services Data from a Connection Pool in Jetty

The SharePoint Excel Services JDBC Driver supports connection pooling: This article shows how to connect faster to SharePoint Excel Services data from Web apps in Jetty.

The CData JDBC driver for SharePoint Excel Services is easy to integrate with Java Web applications. This article shows how to efficiently connect to SharePoint Excel Services data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for SharePoint Excel Services 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 SharePoint Excel Services data source at the level of the Web app, in WEB-INF\jetty-env.xml.

    <Configure id='excelservicesdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="excelservicesdemo" class=""> <Arg><Ref refid="excelservicesdemo"/></Arg> <Arg>jdbc/excelservicesdb</Arg> <Arg> <New class="cdata.jdbc.excelservices.ExcelServicesDriver"> <Set name="url">jdbc:excelservices:</Set> <Set name="URL"></Set> <Set name="User"></Set> <Set name="Password">password</Set> <Set name="File">Book1.xlsx</Set> </New> </Arg> </New> </Configure>

    The URL, User, and Password properties, under the Authentication section, must be set to valid credentials for SharePoint Online, SharePoint 2010, or SharePoint 2013. Additionally, the Library property must be set to a valid SharePoint Document Library and the File property must be set to a valid .xlsx file in the indicated Library.

  4. Configure the resource in the Web.xml:

    jdbc/excelservicesdb javax.sql.DataSource Container
  5. You can then access SharePoint Excel Services with a lookup to java:comp/env/jdbc/excelservicesdb: InitialContext ctx = new InitialContext(); DataSource myexcelservices = (DataSource)ctx.lookup("java:comp/env/jdbc/excelservicesdb");

The steps above show how to configure the driver in a simple connection pooling scenario. For more use cases and information, see the Working with Jetty JNDI chapter in the Jetty documentation.
