somebody pls get me out of this.I am trying to display a list from an sqlite database which worked absolutely fine but dont know what went wrong it showed cant find provider info.I fixed it and then when i am running the code with list_cursor.moveToFirst() it just shows the 1st item in list again and again which proves that it is fetching data....When I use list_cursor.moveToNext() it shows the following exception:PLS HELP ME

EDIT Recursion is required for the counter increment.
I have a GUI that adds entered fields to a ListView, but also adds the name of the object to a TableView beside it and displays four substring counts. They are Plant objects, and it's supposed to display in the ListView (which it does), and then display the name with each occurrence of a certain substring:
See here:
I don't understand what I'm missing, because in my addButtonClick method, I call my recursive method. The logic seems correct to me in the method, so I must be missing something in my Integer properties, or a constructor.
Here is the method in the Controller for the add button click. There is a combo box where a user can choose Flower, Fungus, Weed, or Herb. And when the user clicks a respective plant type, respective radio buttons appear that are related to certain traits. All of that works. I will show the Flower section of code:
/*
Adds respective plant type and resets controls
*/
public void handleAddButtonClick(ActionEvent event) {
if (idInput != null && nameInput != null & colorInput != null) {
if (plantType.getValue().equals("Flower")) {
Flower flower = new Flower(ID, idNum, name, color, smell, thorns, edible, poisonous, flavor, medicine, seasonal);
flower.setID(idInput.getText());
flower.setName(nameInput.getText());
flower.setColor(colorInput.getText());
flower.setSmell(scentedRadio.isSelected());
flower.setThorns(thornyRadio.isSelected());
observablePlantList.add(flower);
//this is where the table information gets added.
//it adds it, just displays 0's.
flower.setPlantName(nameInput.getText());
Plant.substringCounter(name, "e"); //tried flower instead
Plant.substringCounter(name, "ar");//of Plant. still nothing.
Plant.substringCounter(name, "er");
Plant.substringCounter(name, "o");
observableAnalysisList.add(flower);
//just doing some debug printing. this prints 0
System.out.println(Plant.substringCounter(name, "e"));
//more debugging. this prints fine because of toString() method
System.out.println(flower);
Here is the relevant code in the main class and the Flower class:
//Plant Table properties ("e", "o", "ar", "er")
public StringProperty plantName = new SimpleStringProperty(this, "plantName", "");
public String getPlantName() {return plantName.get(); }
public StringProperty plantNameProperty() {return plantName; }
public void setPlantName(String plantName) {this.plantName.set(plantName); }
public IntegerProperty countLetterE = new SimpleIntegerProperty(this, "countLetterE", 0);
public int getLetterE() {return countLetterE.get();}
public IntegerProperty eProperty() {return countLetterE; }
public void setCountLetterE(int countLetterE) {this.countLetterE.set(countLetterE);}
public IntegerProperty countLetterO = new SimpleIntegerProperty(this, "countLetterO", 0);
public int getLetterO() {return countLetterO.get(); }
public IntegerProperty oProperty() {return countLetterO; }
public void setCountLetterO(int countLetterO) {this.countLetterO.set(countLetterO);}
public IntegerProperty countLetterER = new SimpleIntegerProperty(this, "countLetterER", 0);
public int getLetterER() {return countLetterER.get(); }
public IntegerProperty erProperty() {return countLetterER; }
public void setCountLetterER(int countLetterER) {this.countLetterER.set(countLetterER);}
public IntegerProperty countLetterAR = new SimpleIntegerProperty(this, "countLetterAR", 0);
public int getLetterAR() {return countLetterAR.get(); }
public IntegerProperty arProperty() {return countLetterAR; }
public void setCountLetterAR(int countLetterAR) {this.countLetterAR.set(countLetterAR);}
Recursive method:
public static int substringCounter(String plantName, String letters) {
plantName = plantName.toLowerCase();
if(plantName.isEmpty()) {
return 0;
}
if(plantName.indexOf(letters) == -1) {
return 0;
}
return 1 + substringCounter(plantName.substring(plantName.indexOf(letters) + 1), letters);
}
//toString method for Plant class to display in ListView. Works fine.
public String toString() {
return "ID: " + this.ID + "-" + this.idNum + ", Name: " + this.name + ", Color: " + this.color;
}
}
Flower class
public class Flower extends Plant {
public Flower(String ID, int idNum, String name, String color, boolean smell, boolean thorns, boolean edible, boolean poisonous, boolean flavor, boolean medicine, boolean seasonal) {
super(ID, idNum, name, color, smell, thorns, edible, poisonous, flavor, medicine, seasonal);
}
public void setSmell(boolean smell) {
this.smell = smell;
}
public void setThorns(boolean thorns) {
this.thorns = thorns;
}
//toString method for the ListView only. All works fine here
public String toString() {
return super.toString() + ", Scent? " + this.smell + ", Thorns? " + this.thorns;
}
}
I sincerely hope I either 1) gave you enough information, or 2) didn't give you too much information. Thank you all for any help offered.
You are invoking a static method on a string and return a number which effectively results in absolutely nothing when you call it like that:
Plant.substringCounter(name, "e");
You need to modify a property if you want some "action" or at least process the result that's being returned by substringCounter.
Besides, I have no idea why you use recursion. This does the same:
String text = "dandelion";
String search = "d";
int count = 0;
int pos = 0;
if (!search.isEmpty()) {
while ((pos = text.indexOf(search, pos)) != -1) {
count++;
pos++;
}
}
System.out.println(count);
Basically something like this:
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
HBox box = new HBox();
box.setSpacing(10);
TextField sourceTextField = new TextField( "Dandelion");
Label result = new Label();
TextField searchTextField = new TextField();
// add listener for counting the number of substrings
searchTextField.textProperty().addListener(new ChangeListener<String>() {
#Override
public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
String sourceText = sourceTextField.getText().toLowerCase();
String searchText = newValue.toLowerCase();
int count = 0;
int pos = 0;
if( !searchText.isEmpty()) {
while( (pos = sourceText.indexOf( searchText, pos)) != -1) {
count++;
pos++;
}
}
result.setText( String.valueOf(count));
}
});
box.getChildren().addAll( new Label( "Search:"), searchTextField, new Label( "Text:"), sourceTextField, new Label( "Count:"), result);
Scene scene = new Scene(box, 600, 200);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Or using your recursive method (you also need to check letters for empty string by the way):
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
HBox box = new HBox();
box.setSpacing(10);
TextField sourceTextField = new TextField( "Dandelion");
Label result = new Label();
TextField searchTextField = new TextField();
searchTextField.textProperty().addListener(new ChangeListener<String>() {
#Override
public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
String sourceText = sourceTextField.getText().toLowerCase();
String searchText = newValue.toLowerCase();
result.setText( String.valueOf( substringCounter( sourceText, searchText)));
}
});
box.getChildren().addAll( new Label( "Search:"), searchTextField, new Label( "Text:"), sourceTextField, new Label( "Count:"), result);
Scene scene = new Scene(box, 600, 200);
primaryStage.setScene(scene);
primaryStage.show();
}
public static int substringCounter(String plantName, String letters) {
plantName = plantName.toLowerCase();
if(letters.isEmpty()) {
return 0;
}
if(plantName.isEmpty()) {
return 0;
}
if(plantName.indexOf(letters) == -1) {
return 0;
}
return 1 + substringCounter(plantName.substring(plantName.indexOf(letters) + 1), letters);
}
public static void main(String[] args) {
launch(args);
}
}
Instead of setting the label like I did in the example you of course have to change your integer properties.

But this is giving a class not found exception on com.itextpdf.text.pdf.parser.RenderListener at the runtime on hadoop environment. Appreciate any help on this. All the jar files are correctly added on build path and there are no multiple jars as well.
For some reason my blackberry application crashes whenever i try to display a bitmap image from a URL using the internet.
I found the downloadImage() function very easy to understand and to follow compared to others on stackoverflow. The others didnt have any examples on how to implement their function. I have have tested the function downloadImage many times and all failed.
Please give explanation with code example. Thanks.

If you want to Display an Image on BlackBerry Screen from a WebURL. First you need to get a BitMap refrence.
You can Check the below Code:
The Code will take input as WebURL and It will return a Bitmap reference.
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import javax.microedition.io.Connector;
import javax.microedition.io.HttpConnection;
import net.rim.device.api.io.IOUtilities;
import net.rim.device.api.system.Bitmap;
import net.rim.device.api.system.EncodedImage;
public class GetImage {
public static Bitmap connectServerForImage(String url) {
HttpConnection httpConnection = null;
DataOutputStream httpDataOutput = null;
InputStream httpInput = null;
int rc;
Bitmap bitmp = null;
try {
httpConnection = (HttpConnection) Connector.open(url);
rc = httpConnection.getResponseCode();
if (rc != HttpConnection.HTTP_OK) {
throw new IOException("HTTP response code: " + rc);
}
httpInput = httpConnection.openInputStream();
InputStream inp = httpInput;
byte[] b = IOUtilities.streamToBytes(inp);
EncodedImage hai = EncodedImage.createEncodedImage(b, 0, b.length);
return hai.getBitmap();
} catch (Exception ex) {
// System.out.println("URL Bitmap Error........" + ex.getMessage());
} finally {
try {
if (httpInput != null)
httpInput.close();
if (httpDataOutput != null)
httpDataOutput.close();
if (httpConnection != null)
httpConnection.close();
} catch (Exception e) {
e.printStackTrace();
}
}
return bitmp;
}
}
And Finally,If you want to Display the Image on BlackBerry Screen, use the below method
g.drawBitmap(xpos, ypos, w, h, image, 0, 0);//pass the Bitmap reference Here
I see your method: downloadImage(String url). Its a lengthy code. No need that much;
Try this method:
public static Bitmap getImage(String url)
{
Bitmap image;
HttpConnection connection=null;
InputStream is=null;
try
{
connection=(HttpConnection)Connector.open(Utility.escapeHTML(url));
int response=connection.getResponseCode();
if(response==HttpConnection.HTTP_OK)
{
is=connection.openInputStream();
byte[] data=IOUtilities.streamToBytes(is);
connection.close();
image=Bitmap.createBitmapFromBytes(data,0,data.length,1);
}
else
{
image=ResourceList.dummyBit;//noimage.png
}
}
catch (Exception e)
{
image=ResourceList.dummyBit;//noimage.png
}
finally
{
try
{
if (is != null)
is.close();
if (connection != null)
connection.close();
}
catch (Exception e) {}
}
return image;
}
try this and let me know.
the escapeHTML(String str) method is below:
public static String escapeHTML(String s)
{
StringBuffer sb = new StringBuffer();
int n = s.length();
for (int i = 0; i < n; i++) {
char c = s.charAt(i);
switch (c) {
case ' ': sb.append("%20"); break;
default: sb.append(c); break;
}
}
return sb.toString();
}
I have prepared a simple test case to demonstrate my problem.
It is just 1 file which will run instantly when added to a new project.
I would like to have a MainScreen displaying an editable list of items:
and when leaving this screen, the user should be asked - if she wants to save the modified list to persistent storage, by presenting the standard Save/Discard/Cancel-dialog:
I have added setDirty(true) to my menu items and the standard dialog does come up okay.
My problem is: I don't know how to clear the dirty flag after saving - in my current code the Save/Discard/Cancel-dialog comes again and again, even if I just view the ListField, without editing it.

Please share your Blackberry 6 experience, advices in regard to persistent storage are also welcome.
In my real program I'm using KeywordFilterField for viewing a SortedReadableList, so from reading Blackberry docs I suppose, that I must always copy data between SortedReadableList and Vector - because the latter is persistable and the former is not?
setDirty(false) will clear the dirty flag if that is what you are after.
Below is my application code. i want alarm to ring on my blackberry on every 6 of this month whether this apllication is running or not. please guide me in details i am a beginner.

What are the benefits of integrating with the built-in alarm application? Would it be better for your application to place an event in the device's calendar and make the event show a reminder?
If you have to have a more prominent alarm, why not do it yourself? An alarm is an action the phone does (either make a sound and/or vibrate) that shows on the screen why it is taking that action and the action stops when someone responds to it.
Can you just make an app that starts in the background, checks the day, and makes a sound/vibrates on that day?
The default Alarm app on my phone only supports one time to ring. If I set it to wake me up at 4 a.m., but your app reschedules the alarm on my phone for 8 a.m., you would instantly lose a customer (after I wake up 4 hours too late).
