Connect to Elasticsearch from a Connection Pool in WebLogic


Use the CData JDBC Driver for Elasticsearch to connect to Elasticsearch data from Web applications running on WebLogic.

WebLogic

The CData JDBC Driver for Elasticsearch enables you to follow standard procedures to integrate Elasticsearch data into Java Web applications. This article shows how to deploy the CData JDBC Driver for Elasticsearch in WebLogic server.

Install the JDBC Driver in WebLogic Server

Add the driver JAR and license file to the classpath your application will be using. The .lic file must be located in the same folder as the JAR. These files are located in the lib subfolder of the installation directory.

If you want to add the driver to all domains, add the JAR to the WEBLOGIC_CLASSPATH environment variable. add the following line to the commEnv.cmd/sh script in WL_HOME\common\bin\.

set WEBLOGIC_CLASSPATH=your-installation-directory\lib\cdata.jdbc.elasticsearch.jar;%WEBLOGIC_CLASSPATH%

If you want to add the driver to a specific domain, you will need to add the JAR to the PRE_CLASSPATH environment variable. Add the following line to the setDomainEnv.cmd/sh script in the bin subfolder of the folder for that domain:

set PRE_CLASSPATH=your-installation-directory\lib\cdata.jdbc.elasticsearch.jar;%PRE_CLASSPATH%

Create a JDBC Data Source for Elasticsearch

After installing the driver, create the connection.

  1. In the Domain Structure tree, click Services -> Data Sources -> New -> Generic Data Source.
  2. On the JDBC Data Source Properties page, enter the following information:
    • Name: Enter a user-friendly name; for example, elasticsearchjdbc.
    • JDBC Name: Enter the path the JDBC data source will be bound to; for example, jdbc/Elasticsearch.
    • Database Type: Select Other.

    A user-friendly name and the path to bind to. (Salesforce is shown.)

  3. Click Next to use the default options. On the last page, enter the following information and click Test Configuration:

    • Driver Class Name: Enter the driver class, cdata.jdbc.elasticsearch.ElasticsearchDriver, in this property.

    • URL: Enter the JDBC URL. A typical JDBC URL is below:

      jdbc:elasticsearch:Server=127.0.0.1;Port=9200;User=admin;Password=123456;

      接続するには、Server およびPort 接続プロパティを設定します。 認証には、User とPassword プロパティ、PKI (public key infrastructure)、またはその両方を設定します。 PKI を使用するには、SSLClientCert、SSLClientCertType、SSLClientCertSubject、およびSSLClientCertPassword プロパティを設定します。

      本製品は、認証とTLS/SSL 暗号化にX-Pack Security を使用しています。TLS/SSL で接続するには、Server 値に'https://' を接頭します。Note: PKI を 使用するためには、TLS/SSL およびクライアント認証はX-Pack 上で有効化されていなければなりません。

      接続されると、X-Pack では、設定したリルムをベースにユーザー認証およびロールの許可が実施されます。

    • Database User Name: Enter the username, if not specified in the JDBC URL.
    • Password: Enter the password, if not specified in the JDBC URL.
    Driver connection properties. (Salesforce is shown.)

After selecting the server where you want to deploy the JDBC data source, you can now connect to Elasticsearch data.

The data source deployed on the target server and enabled for connection pooling. (Salesforce is shown.)

More WebLogic Integration

The steps above show how configure the driver in a simple connection pooling scenario. For more use cases and information, see the JDBC sections in the WebLogic Data Sources chapter of the Oracle Fusion Middleware documentation.
