Populatin a JList with elements from a DB (access here)

Question

last year i was able to populate a JList with data from a database
however this year something doesnt work
this is last year
public String[] getOnderwerpen()
System.out.println(theConnection==null?" connection null ":" connection niet null ");
String []locaties = new String[30];
ArrayList returnLijst;
returnLijst = new ArrayList();
ArrayList arraylist;
arraylist = new ArrayList();
          String[] deLocaties = null;
try{
String onderwerpQuery = "SELECT OnderwerpID FROM Onderwerp order by OnderwerpID";
Statement statement = theConnection.createStatement();
System.out.println(statement==null?" statement null ":" statement niet null ");
statement.execute(onderwerpQuery);
ResultSet result = statement.getResultSet();
System.out.println(result==null?" ResultSet null ":" ResultSet niet null ");
int i = 0;
               while(result.next())
          //          locaties[i] = result.getString("OnderwerpID");
locaties[i] = result.getString("OnderwerpID");
                                        i++;
deLocaties = new String;
          for (int j=0;j<deLocaties.length;j++)
               deLocaties[j] = locaties[j];
          sorteerStringArray(deLocaties);
}//end-try
catch (Exception e) {
e.printStackTrace();
return deLocaties;
& this is what i did this year
public String[] getbedrijfNaam()
          String[] bedrijfsNamen = new String[Constanten.aantalBedrijven];
          String[] deBedrijfsNamen = null;
     System.out.println(theConnection==null?" connection null ":" connection niet null ");
     System.out.println("test this");
     try{
     String onderwerpQuery = "SELECT naam FROM organisatie";
     Statement statement = theConnection.createStatement();
     System.out.println(statement==null?" statement null ":" statement niet null ");
     statement.execute(onderwerpQuery);
     ResultSet result = statement.getResultSet();
     int i = 0;
                    while(result.next())
                         bedrijfsNamen[i] = result.getString();
                                             i++;
                    deBedrijfsNamen = new String[i];
               for (int j=0;j<deBedrijfsNamen.length;j++)
                    deBedrijfsNamen[j] = bedrijfsNamen[j];
               sorteerStringArray(deBedrijfsNamen);
               statement.close();
               //theConnection.close();
     }//end-try
     catch (Exception e) {
     e.printStackTrace();
     return deBedrijfsNamen;
is there something here thats not right
or does this no longer work because of the changes made in 1.5
