JWKTL - Can't connect to database

I'm trying to install the JWKTL library into a Java project. JWKTL Getting started

Now I downloaded the dump file as described, and parsed it into a new directory.

My code is: 

package main;

import java.io.File;
import java.util.List;

import de.tudarmstadt.ukp.jwktl.JWKTL;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryEdition;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryEntry;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryPage;
import de.tudarmstadt.ukp.jwktl.api.IWiktionaryRelation;
import de.tudarmstadt.ukp.jwktl.api.PartOfSpeech;
import de.tudarmstadt.ukp.jwktl.api.RelationType;


public class Main {

    final static String PATH_TO_DUMP_FILE = "/GetWords/enwiktionary-20160601-pages-articles-multistream.xml";
    final static String TARGET_DIRECTORY = "/GetWords/";
    final static boolean OVERWRITE_EXISTING_FILES = true;
    /**
     * Simple example which parses an English dump file and prints the entries for the word <i>Wiktionary</i>
     * @param args name of the dump file, output directory for parsed data, ISO language code of the Wiktionary entry language (en/de), boolean value that specifies if existing parsed data should be deleted
     */
        public static void main(String[] args) throws Exception {
            File dumpFile = new File(PATH_TO_DUMP_FILE);
              File outputDirectory = new File(TARGET_DIRECTORY);
              boolean overwriteExisting = OVERWRITE_EXISTING_FILES;

              JWKTL.parseWiktionaryDump(dumpFile, outputDirectory, overwriteExisting);

              IWiktionaryEdition wkt = JWKTL.openEdition(TARGET_DIRECTORY);

              //TODO: Query the data you need.

              // Close the database connection.
              wkt.close();
}
}

But the line: IWiktionaryEdition wkt = JWKTL.openEdition(TARGET_DIRECTORY); throws an error: The method openEdition(File) in the type JWKTL is not applicable for the arguments (String), when I try to enter the dump_file as java.io.File

the program throws the following error:

    ... 4 more

Does anybody know how to fix this?

I use Java 8 in Eclipse Mars.

I installed these libs:

  • jwktl-1.0.1.jar
  • je-6.4.25.jar
  • apache-ant-1.8.2.jar

Thank you!

Solution

  • I solved it... It was too simple:

    The sulution is:

    File f = new File(TARGET_DIRECTORY);

IWiktionaryEdition wkt = JWKTL.openEdition(f);

    Best regards!
