Connect to LDAP Objects from a Connection Pool in Jetty

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

   <Configure id='ldapdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="ldapdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="ldapdemo"/></Arg>
    <Arg>jdbc/ldapdb</Arg>
    <Arg>
    <New class="cdata.jdbc.ldap.LDAPDriver">
    <Set name="url">jdbc:ldap:</Set>
    <Set name="User">Domain\BobF</Set>
    <Set name="Password">bob123456</Set>
    <Set name="Server">10.0.1.1</Set>
    <Set name="Port">389</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   To establish a connection, the following properties under the Authentication section must be provided:

   • Valid User and Password credentials (e.g., Domain\BobF or cn=Bob F,ou=Employees,dc=Domain).
   • Server information, including the IP or host name of the Server, as well as the Port.

   • BaseDN: This will limit the scope of LDAP searches to the height of the distinguished name provided.

     Note: Specifying a narrow BaseDN may greatly increase performance; for example, cn=users,dc=domain will only return results contained within cn=users and its children.

4. Configure the resource in the Web.xml:

    jdbc/ldapdb
    javax.sql.DataSource
    Container
   
   

5. You can then access LDAP with a lookup to java:comp/env/jdbc/ldapdb:

   InitialContext ctx = new InitialContext();
   DataSource myldap = (DataSource)ctx.lookup("java:comp/env/jdbc/ldapdb");
