Do not use WebLogic-specific JDBC properties or extensions

This rule detects the use of WebLogic-specific strings and classes that are used for JDBC.

WebLogic-specific strings


The following string literals are detected.

• weblogic.jdbc.rmi.Driver
• jdbc:weblogic:rmi
• jdbc:weblogic:jts
• weblogic.server.url
• weblogic.jdbc.datasource
• weblogic.user
• weblogic.credential

For example, the following code will be detected:

• propertiess.put("weblogic.jdbc.datasource", "myDataSource").newInstance();
• java.sql.Driver myDriver = (java.sql.Driver) Class.forName("weblogic.jdbc.rmi.Driver").newInstance();

WebLogic JDBC Extension


Instances of the following objects, or the cast operations are detected.

• weblogic.jdbc.extensions.WLConnection
• weblogic.jdbc.vendor.oracle.OracleConnection
• weblogic.jdbc.vendor.oracle.OracleArray
• weblogic.jdbc.vendor.oracle.OracleStruct
• weblogic.jdbc.vendor.oracle.OracleRef
• weblogic.jdbc.vendor.oracle.OracleThinBlob
• weblogic.jdbc.vendor.oracle.OracleThinClob

The following code shows examples of detecting WLConnection object usage:

• Object instance (Qualified Type): weblogic.jdbc.extensions.WLConnection myWLConnection
• Object instance (Simple Type): WLConnection myWLConnection2
• Object Cast (Qualified Type): java.sql.Connection vendorConn = ((weblogic.jdbc.extensions.WLConnection) myConnection).getVendorConnection();
• Object cast (Simple Type) java.sql.Connection vendorConn = ((WLConnection) myConnection).getVendorConnection();

The Simple Type cases are detected as long as one of these two import statements is present:

• import weblogic.jdbc.extensions.WLConnection;
• import weblogic.jdbc.extensions.*;
