Yes, I ran into the same issue and "fix" in some of my non-Jena work.

I'm getting the following compile time error when building with maven. [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project jena-jdbc-core: Compilation failure: Compilation failure: [ERROR] /home/afs/Jena/jena-jdbc/jena-jdbc-core/src/main/java/org/apache/jena/jdbc/metadata/results/MetaResultSet.java:[51,8] org.apache.jena.jdbc.metadata.results.MetaResultSet is not abstract and does not override abstract method <T>getObject(java.lang.String,java.lang.Class<T>) in java.sql.ResultSet and then some others. Maybe it's this: http://stackoverflow.com/questions/7692320/is-there-really-resultset-getobjectstring-classt-in-jdk7 I'm using a Java7 compiler in Java6 mode so it's the JDK7 runtime. If so, the fix is to add, without @Override but with suppressed warnings: <T> T getObject(int columnIndex, Class<T> type) throws SQLException <T> T getObject(String columnLabel, Class<T> type) throws SQLException Andy
