java - Full Dataset Export blank dataset -

-

i have database in libreoffice base (debian) need export tables xml file. have created piece of eclipse java code follows:

package newdb;  import java.io.fileoutputstream; import java.sql.connection; import java.sql.drivermanager; import java.sql.sqlexception;  import org.dbunit.database.databaseconnection; import org.dbunit.database.idatabaseconnection; import org.dbunit.database.querydataset; import org.dbunit.dataset.idataset; import org.dbunit.dataset.xml.flatxmldataset; import org.dbunit.dataset.datasetexception;   public class extracttestdataset { public static void main(string[] args) throws exception {     // database connection     class driverclass = class.forname("org.hsqldb.jdbcdriver");     connection jdbcconnection = drivermanager.getconnection "jdbc:hsqldb:/home/debian/documents/database.odb", "sa", "");      idatabaseconnection connection = new databaseconnection(jdbcconnection);      // full database export     idataset fulldataset = connection.createdataset();       flatxmldataset.write(fulldataset, new fileoutputstream("/home/debian/documents/fulldataset.xml"));      } }

after looking @ dbunit pages , other various sites code should correct; database populated, connections valid, there no warnings or errors in code, when xml file created content follows:

<?xml version='1.0' encoding='utf-8'?> <dataset/>

does have ideas why dataset not being exported?

thanks

turns out .odb database connected different backend, explaining blank dataset.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
