Hi, Not sure if this is a bug or not, so decided to ask here first. After updagrading my MariaDB Connector/Java from 2.7.12 to 3.5.4 I got the following problem using Commons BeanUtils: if the query results in computed NULL values, constructing RowSetDynaClass from the result set throws SQLException. Apparently metadata.getColumnClassName(i) now returns "byte[]", for which Class.forName does not work and loadClass fails. Minimal reproducible example:
String sql = "SELECT NULL AS test FROM DUAL;"; PreparedStatement stmt = conn.prepareStatement(sql); ResultSet rset = stmt.executeQuery(); RowSetDynaClass rsdc = new RowSetDynaClass(rset); results in java.sql.SQLException: Cannot load column class 'byte[]': java.lang.ClassNotFoundException: byte[] at org.apache.commons.beanutils.JDBCDynaClass.loadClass(JDBCDynaClass.java:274) at org.apache.commons.beanutils.JDBCDynaClass.createDynaProperty(JDBCDynaClass.java:121) at org.apache.commons.beanutils.JDBCDynaClass.introspect(JDBCDynaClass.java:238) at org.apache.commons.beanutils.RowSetDynaClass.<init>(RowSetDynaClass.java:207) Any thoughts? - Jukka Toivanen --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
