Connect to SAS xpt from a Connection Pool in WebLogic

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

Deploy the JDBC Driver in WebLogic Server

To deploy the driver, add the driver JAR to your classpath. 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, prepend the path to the JAR to the WEBLOGIC_CLASSPATH environment variable in WL_HOME\common\bin\commEnv.cmd/sh. This script is located in WL_HOME\common\bin\. For example:

In WebLogic 12.2.1 if you want to add the driver to a specific domain, you can simply place the driver JAR and .lic file into DOMAIN_HOME\lib; for example, ORACLE_HOME\user_projects\domains\MY_DOMAIN\lib. These files will be added to the server classpath at startup.

Earlier versions require that you manually add the driver to the classpath: Prepend the following to the PRE_CLASSPATH environment variable in setDomainEnv.cmd/sh. This script is located in the bin subfolder of the folder for that domain.

After making these changes, restart the server.

Create a JDBC Data Source for SAS xpt

After deploying the driver, log into the WebLogic Administration Console and 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, sasxptjdbc.
   • JNDI Name: Enter the path the JDBC data source will be bound to; for example, jdbc/SASXpt.

   • Database Type: Select Other.

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.sasxpt.SASXptDriver.

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

     jdbc:sasxpt:URI=C:/folder;

     Connecting to Local SASXpt Files

     You can connect to local SASXpt file by setting the URI to a folder containing SASXpt files.

     Connecting to S3 data source

     You can connect to Amazon S3 source to read SASXpt files. Set the following properties to connect:

     • URI: Set this to the folder within your bucket that you would like to connect to.
     • AWSAccessKey: Set this to your AWS account access key.
     • AWSSecretKey: Set this to your AWS account secret key.
     • TemporaryLocalFolder: Set this to the path, or URI, to the folder that is used to temporarily download SASXpt file(s).

     Connecting to Azure Data Lake Storage Gen2

     You can connect to ADLS Gen2 to read SASXpt files. Set the following properties to connect:

     • URI: Set this to the name of the file system and the name of the folder which contacts your SASXpt files.
     • AzureAccount: Set this to the name of the Azure Data Lake storage account.
     • AzureAccessKey: Set this to our Azure DataLakeStore Gen 2 storage account access key.
     • TemporaryLocalFolder: Set this to the path, or URI, to the folder that is used to temporarily download SASXpt file(s).

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the SAS xpt JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.sasxpt.jar

     Fill in the connection properties and copy the connection string to the clipboard.

   • Database User Name: Enter the username, if not specified in the JDBC URL.
   • Password: Enter the password, if not specified in the JDBC URL.

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

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.
