The soon generated Embedded Connection jar will have a dependency on the regular JDBC driver jar. The JDBC driver jar is independent, however if attempted to create an Embedded Connection with will try to load the respective class from the class loader, failing if the Embedded Connection jar is not present. If anyone in the group has expertise on Java Class dynamic loading, please contact me because there might be issues on this. Removed the pom.xml file because the regular maven compilation fails.

If anyone in the group has expertise on Java Class dynamic loading, please contact me because there might be issues on this. Removed the pom.xml file because the regular maven compilation fails.

073ee535234b Ok. Now everything compiles back with Ant again. Moved the Embedded stuff to the temporary MonetDBJavaLite repository before moving into the suggested MonetDBLite repository. The soon generated Embedded Connection jar will have a dependency on the regular JDBC driver jar. The JDBC driver jar is independent, however if attempted to create an Embedded Connection with will try to load the respective class from the class loader, failing if the Embedded Connection jar is not present. If anyone in the group has expertise on Java Class dynamic loading, please contact me because there might be issues on this. Removed the pom.xml file because the regular maven compilation fails.

073ee535234b Ok. Now everything compiles back with Ant again. Moved the Embedded stuff to the temporary MonetDBJavaLite repository before moving into the suggested MonetDBLite repository. The soon generated Embedded Connection jar will have a dependency on the regular JDBC driver jar. The JDBC driver jar is independent, however if attempted to create an Embedded Connection with will try to load the respective class from the class loader, failing if the Embedded Connection jar is not present. If anyone in the group has expertise on Java Class dynamic loading, please contact me because there might be issues on this. Removed the pom.xml file because the regular maven compilation fails.

The soon generated Embedded Connection jar will have a dependency on the regular JDBC driver jar. The JDBC driver jar is independent, however if attempted to create an Embedded Connection with will try to load the respective class from the class loader, failing if the Embedded Connection jar is not present. If anyone in the group has expertise on Java Class dynamic loading, please contact me because there might be issues on this. Removed the pom.xml file because the regular maven compilation fails.

The soon generated Embedded Connection jar will have a dependency on the regular JDBC driver jar. The JDBC driver jar is independent, however if attempted to create an Embedded Connection with will try to load the respective class from the class loader, failing if the Embedded Connection jar is not present. If anyone in the group has expertise on Java Class dynamic loading, please contact me because there might be issues on this. Removed the pom.xml file because the regular maven compilation fails.
