Description: The JRun Tag Library (JTL), JRun's JSP custom tag library, has been changed in JRun 3.1 to provide a standard API (application programming interface) for working with result sets returned by the sql, storedproc, getmsg, getmail, and jndi tags. These tags now return Java objects that implement the JDBC javax.sql.RowSet interface, which extends java.sql.ResultSet. Since each tag uses SQL-like syntax to retrieve tabular data.
