  • Can someone explain this color wheel code to me?

    - by user1869438
    I just started doing java and i need some help with understanding this code. I got it from a this website. This is supposed to be code for a color wheel but i don't really understand how it works, especially the final ints STEPS and SLICES. import java.awt.Color; import objectdraw.*; public class ColorWheel extends WindowController { private double brightness; private Text text; private FilledRect swatch; private Location center; private int size; private FilledRect brightnessOverlay; private static final int SLICES = 96; private static final int STEPS = 16; public void begin() { canvas.setBackground(Color.BLACK); brightness = 1.; size = Math.min(canvas.getWidth(), canvas.getHeight() - 20); center = new Location(canvas.getWidth() / 2, size / 2); for(int j = STEPS; j >= 1; j--) { int arcSize = size * j / STEPS; int x = center.getX() - arcSize / 2; int y = center.getY() - arcSize / 2; for(int i = 0; i < SLICES; i++) { Color c = Color.getHSBColor((float)i / SLICES, (float)j / STEPS, (float)brightness); new FilledArc(x, y, arcSize, arcSize, i * 360. / SLICES, 360. / SLICES + .5, c, canvas); } } swatch = new FilledRect(0, canvas.getHeight() - 20, canvas.getWidth(), 20, Color.BLACK, canvas); brightnessOverlay = new FilledRect(0, 0, canvas.getWidth(), canvas.getHeight() - 20, new Color(0, 0, 0, 0), canvas); text = new Text("", canvas.getWidth() / 2, canvas.getHeight() - 18, canvas); text.setAlignment(Text.CENTER, Text.TOP); text.setBold(true); } public void onMouseDrag(Location point) { brightness = (canvas.getHeight() - point.getY()) / (double)(canvas.getHeight()); if(brightness < 0) { brightness = 0; } else if(brightness > 1) { brightness = 1; } if(brightness < .5) { text.setColor(Color.WHITE); } else { text.setColor(Color.BLACK); } brightnessOverlay.setColor(new Color(0f, 0f, 0f, (float)(1 - brightness))); } public void onMouseMove(Location point) { double saturation = 2 * center.distanceTo(point) / size; if(saturation > 1) { text.setText(""); swatch.setColor(Color.BLACK); return; } double hue = -Math.atan2(point.getY() - center.getY(), point.getX() - center.getX()) / (2 * Math.PI); if(hue < 0) { hue += 1; } swatch.setColor(Color.getHSBColor((float)hue, (float)saturation, (float)brightness)); text.setText("Color.getHSBColor(" + Text.formatDecimal(hue, 2) + "f, " + Text.formatDecimal(saturation, 2) + "f, " + Text.formatDecimal(brightness, 2) + "f)"); } }

  • Logcat error: "addView(View, LayoutParams) is not supported in AdapterView" in a ListView

    - by HacKreatorz
    I'm doing an aplication for Android and something I need is that it shows a list of all files and directories in the SD Card and it has to be able to move through the different directories. I found a good tutorial in anddev: http://bit.ly/h4GyFC I modified a few things so the aplication moves in the SD Card and not in Android root Directories but the rest is mostly the same. This is my xml file for the activity: <?xml version="1.0" encoding="utf-8"?> <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@id/android:list" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" /> </ListView> And this is the code for the Activity: import hackreatorz.cifrador.R; import java.io.File; import java.util.ArrayList; import android.app.ListActivity; import android.content.res.Configuration; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.Toast; public class ArchivosSD extends ListActivity { private ArrayList<String> directoryEntries = new ArrayList<String>(); private File currentDirectory = new File("/sdcard/"); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); browseToSD(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); } private void browseToSD() { browseTo(new File("/sdcard/")); } private void upOneLevel() { if(this.currentDirectory.getParent() != null) this.browseTo(this.currentDirectory.getParentFile()); } private void browseTo(final File directory) { if (directory.isDirectory()) { this.currentDirectory = directory; fill(directory.listFiles()); } else { Toast.makeText(ArchivosSD.this, this.directoryEntries.get(this.getSelectedItemPosition()), Toast.LENGTH_SHORT).show(); } } private void fill(File[] files) { this.directoryEntries.clear(); this.directoryEntries.add(getString(R.string.current_dir)); if(this.currentDirectory.getParent() != null) this.directoryEntries.add(getString(R.string.up_one_level)); int currentPathStringLength = (int) this.currentDirectory.getAbsoluteFile().length(); for (File file : files) { this.directoryEntries.add(file.getAbsolutePath().substring(currentPathStringLength)); } setListAdapter(new ArrayAdapter<String>(this, R.layout.archivos_sd, this.directoryEntries)); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { int selectionRowID = (int) this.getSelectedItemPosition(); String selectedFileString = this.directoryEntries.get(selectionRowID); if (selectedFileString.equals(".")) { this.browseToSD(); } else if(selectedFileString.equals("..")) { this.upOneLevel(); } else { File clickedFile = null; clickedFile = new File(this.currentDirectory.getAbsolutePath() + this.directoryEntries.get(selectionRowID)); if(clickedFile != null) this.browseTo(clickedFile); } } } I don't get any errores in Eclipse, but I get a Force Close when running the aplication on my phone and when I look at Logcat I see the following: 01-01 23:30:29.858: ERROR/AndroidRuntime(14911): FATAL EXCEPTION: main *01-01 23:30:29.858: ERROR/AndroidRuntime(14911): java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView* I don't have a clue what to do, I've looked up in Google and I didn't find anything and I did the same at stackoverflow. This is my first aplication in Java and for Android so I'm a real n00b and if the answer was there, I didn't understand it so I would really apreciate if you could explain what I should do to fix this error and why. Thanks for everything in advanced.

  • Flash Mouse.hide() cmd+tab(alt+tab) bring the mouse back

    - by DickieBoy
    Having a bit of trouble with Mouse.show() and losing focus of the swf This isn't my demo: but its showing the same bug http://www.foundation-flash.com/tutorials/as3customcursors/ What i do to recreate it is: mouse over the swf, hit cmd+tab to highlight another window, result is that the mouse is not brought back and is still invisible, (to get it back go to the window bar at the top of the screen and click something). I have an area in which movement is detected and an image Things I have tried package { import flash.display.Sprite; import flash.display.MovieClip; import com.greensock.*; import flash.events.*; import flash.utils.Timer; import flash.events.TimerEvent; import flash.utils.*; import flash.ui.Mouse; public class mousey_movey extends MovieClip { public var middle_of_the_flash; //pixels per second public var speeds = [0,1,3,5,10]; public var speed; public var percentage_the_mouse_is_across_the_screen; public var mouse_over_scrollable_area:Boolean; public var image_move_interval; public function mousey_movey() { middle_of_the_flash = stage.stageWidth/2; hot_area_for_movement.addEventListener(MouseEvent.MOUSE_OVER, mouseEnter); hot_area_for_movement.addEventListener(MouseEvent.MOUSE_OUT, mouseLeave); hot_area_for_movement.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove); stage.addEventListener(Event.MOUSE_LEAVE, show_mouse); stage.addEventListener(MouseEvent.MOUSE_OUT, show_mouse); stage.addEventListener(Event.DEACTIVATE,show_mouse); hot_area_for_movement.alpha=0; hot_area_for_movement.x=0; hot_area_for_movement.y=34; } public function show_mouse(e) { trace(e.type) trace('show_mouse') Mouse.show(); } public function onActivate(e) { trace('activate'); Mouse.show(); } public function onDeactivate(e) { trace('deactivate'); } public function get_speed(percantage_from_middle):int { if(percantage_from_middle > 80) { return speeds[4] } else { if(percantage_from_middle > 60) { return speeds[3] } else { if(percantage_from_middle > 40) { return speeds[2] } else { if(percantage_from_middle > 20) { return speeds[1] } else { return 0; } } } } } public function mouseLeave(e:Event):void{ Mouse.show(); clearInterval(image_move_interval); } public function mouseEnter(e:Event):void{ Mouse.hide(); image_move_interval = setInterval(moveImage,1); } public function mouseMove(e:Event):void { percentage_the_mouse_is_across_the_screen = Math.round(((middle_of_the_flash-stage.mouseX)/middle_of_the_flash)*100); speed = get_speed(Math.abs(percentage_the_mouse_is_across_the_screen)); airplane_icon.x = stage.mouseX; airplane_icon.y = stage.mouseY; } public function stageMouseMove(e:Event):void{ Mouse.show(); } public function moveImage():void { if(percentage_the_mouse_is_across_the_screen > 0) { moving_image.x+=speed; airplane_icon.scaleX = -1; } else { moving_image.x-=speed; airplane_icon.scaleX = 1; } } } } Nothing too fancy, im just scrolling an image left of right at a speed which is generated by how far you are from the middle of the stage, and making an airplane moveclip follow the mouse. The events: stage.addEventListener(Event.MOUSE_LEAVE, show_mouse); stage.addEventListener(MouseEvent.MOUSE_OUT, show_mouse); stage.addEventListener(Event.DEACTIVATE,show_mouse); All fire and work correctly when in the browser, seem a little buggy when running a test through flash, was expecting this as ive experienced it before. The deactivate call even runs when testing and cmd+tabbing but shows no mouse. Any help on the matter is appreciated Thanks, Dickie

  • RadioGroup onCheckedChanged function won't fire

    - by user1758088
    First time/long time. My app keeps track of restaurant servers' shift sales to help them budget. In the activity that displays past shifts, I've created a RadioGroup under the ListView so the server can choose lunch, dinner, or both. I've implemented RadioGroup.onCheckedChangeListener, but onCheckChanged never gets called. I also tried an anonymous inner class as listener, same result. I tried to copy/modify code from this answer: http://stackoverflow.com/a/9595528 ...but when I added the @Override to the callback function, the Eclipse compiler gave me an error (not warning) that the method must override a superclass, and the quick fix was to remove the override. I'm pretty sure the signatures are correct, as they were made with Eclipse's autocomplete and implement methods facilities. I then followed instructions to move my java compiler from 1.5 to 1.6, and none of the above listed behavior seemed to change. Here's the code I thing is relavent: public class DataActivity extends ListActivity implements OnCheckedChangeListener{ RadioButton rbBoth; RadioButton rbDinnerOnly; RadioButton rbLunchOnly; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.database); ... final RadioGroup rgGroup = (RadioGroup)findViewById(R.id.DataRadioGroup); rbBoth = (RadioButton)findViewById(R.id.RadioBoth); rbDinnerOnly = (RadioButton)findViewById(R.id.RadioDinnerOnly); rbLunchOnly = (RadioButton)findViewById(R.id.RadioLunchOnly); rgGroup.setOnCheckedChangeListener(this); populateAllShifts(); } ... public void onCheckedChanged(RadioGroup group, int checkedId) { rbLunchOnly.setText("Click!"); Toast.makeText(getApplicationContext(), "Lunch Only", Toast.LENGTH_LONG).show(); if(group.getCheckedRadioButtonId() == R.id.RadioBoth){ populateAllShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioLunchOnly){ populatLunchShifts(); return; } if(group.getCheckedRadioButtonId() == R.id.RadioDinnerOnly){ populateDinnerShifts(); return; } } There is a ListView in this class with a custom adapter, but if my understanding and my XML are correct, the RadioGroup should be outside of the list: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/llDataLayout" android:weightSum="5" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <ListView android:layout_weight="4" android:layout_width="fill_parent" android:id="@android:id/list" android:layout_height="wrap_content"></ListView> <RadioGroup android:layout_weight="1" android:id="@+id/DataRadioGroup" android:orientation="horizontal" android:layout_height="wrap_content" android:layout_width="fill_parent"> <RadioButton android:text="Lunch and Dinner" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioBoth"/> <RadioButton android:text="Dinner Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioDinnerOnly"/> <RadioButton android:text="Lunch Only" android:textSize="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/RadioLunchOnly"/> </RadioGroup> </LinearLayout> Any ideas out there?

  • Looking for suggestions on how to reuse AlertDialogs to confirm actions of contextual menus on the items of an ActivityList

    - by Ozone
    I use a ListActivity to display a list of items. The user can long-press an item in the list to display a contextual menu. This menu contains among other things an option to delete the long-pressed item. When the user selects this option, a dialog pops up asking for confirmation of the deletion. Upon confirmation, the item is deleted from the list. I would like to reuse the AlertDialog as much as possible. My attempts at using onPrepareDialog(int, View, Bundle) have been defeated by the fact that the Bundle is not passed to the DialogInterface.OnClickListener. I end up having to recreate a listener on every invocation. I see several ways to solve this: recreate the dialog on every occasion (pros: simple, cons: wasteful) keep the DialogInterface.OnClickListener in a field on the ListActivity and keep the item to be deleted as a field of the listener. (pros: no memory waste, cons: need to manage state). Q: is this safe? have onPrepareDialog update the title, and bind new View.OnClickListeners on the buttons of the AlertDialog. (pros: limit waste, cons: new View.OnClickListener on every invocation). If DialogInterface.OnClickListener accepted a Bundle, I wouldn't have to jump through hoops to keep track of the item being deleted. This is not a blocker, but I would love to see an elegant solution. I would love to hear your suggestions :) Here is the code for option #1, if you want to play with this: public class Example extends ListActivity { private static final int CONFIRM_DELETE_DIALOG = 1; private static final String POSITION_KEY = "position"; private ArrayAdapter<String> mAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mAdapter = new ArrayAdapter<String>( this, android.R.layout.simple_list_item_1, new String[] { "one", "two" }); setListAdapter(mAdapter); registerForContextMenu(getListView()); } @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); getMenuInflater().inflate(R.menu.my_lovely_menu, menu); } @Override public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); switch (item.getItemId()) { case R.id.delete_item: Bundle bundle = new Bundle(); bundle.putInt(POSITION_KEY, info.position); showDialog(CONFIRM_DELETE_DIALOG, bundle); return true; default: return super.onContextItemSelected(item); } } @Override protected Dialog onCreateDialog(int id, Bundle args) { switch (id) { case CONFIRM_DELETE_DIALOG: final int position = args.getInt(POSITION_KEY); AlertDialog.Builder builder = new AlertDialog.Builder(); builder.setCancelable(false); builder.setTitle(String.format( getString(R.string.confirm_delete), mAdapter.getItem(position))); DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { switch (which) { case DialogInterface.BUTTON_POSITIVE: mAdapter.remove(mAdapter.getItem(position)); // Dismiss the dialog to ensure OnDismissListeners are notified. dialog.dismiss(); break; case DialogInterface.BUTTON_NEGATIVE: // Cancel the dialog to ensure OnCancelListeners are notified. dialog.cancel(); break; } // Remove the dialog so it is re-created next time it is required. removeDialog(CONFIRM_DELETE_DIALOG); } }; builder.setPositiveButton(android.R.string.yes, listener); builder.setNegativeButton(android.R.string.no, listener); return builder.create(); default: return super.onCreateDialog(id, args); } } }

  • I'm trying to make lots of the same object appear randomly on the screen subject to conditions and k

    - by Katsideswide
    Hi! A good friend recommended this site to me, it looks really useful! I'm a bit of a shameless noob at actionscript and after 3 days of tutorials and advice I've hit a brick wall. I've managed to get a sensor attached to an arduino talking to flash using something called AS3glue. it works, when i set up a trace("leaf") for the contition that the sensor reads 0, i get a printout of the word "leaf". however i want the program to make a graphic appear on the screen when this condition is met, not just trace something. I'm trying to get the program to generate a library object called "Enemy" on the screen at a random position each time the conditions are met. It's called enemy because I was following a game tutorial...actually it's a drawing of a leaf. Here's the bit of the code which is causing me problems: var army:Array; var enemy:Enemy; function AvoiderGame() { army = new Array(); var newEnemy = new Enemy( 100, 100 ); army.push( newEnemy ); addChild( newEnemy ); } function timerEvent(event:Event):void { if (a.getAnalogData(0) ==0 && a.getAnalogData(0) != this.lastposition){ trace("leaf"); var randomX:Number = (Math.random() * 200) + 100; var randomY:Number = (Math.random() * 150) + 50; var newEnemy = new Enemy( randomX, randomY); army.push( newEnemy ); addChild( newEnemy ); } else if (a.getAnalogData(0) == 0) { //don't trace anything } else { //don't trace anything } this.lastposition = a.getAnalogData(0); //afterwards, set the position to be the new lastposition and repeat. } I've imported "import flash.display.MovieClip;" and the code for the Enemy class looks like this: package { import flash.display.MovieClip; public class Enemy extends MovieClip { public function Enemy( startX:Number, startY:Number ) { x = startX; y = startY; } } } Here's my error. I've tried googling, it seems like a pretty general error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at as3glue_program_fla::MainTimeline/timerEvent() at flash.utils::Timer/_timerDispatch() at flash.utils::Timer/tick() I've made sure that the "Enemy" object is exported for AS3. I'm going for something like this when it's programmed in AS2: leafCounter = 0; //set the counter to 0 counter.swapDepths(1000); //puts the counter on top of pretty much anything, unless you make more than 1000 leaves! counter.textbox.text = 0; //shows "0" in the text box in the "counter" movie clip this.onMouseDown = function() { //triggers when the mouse is clicked this.attachMovie("Leaf","Leaf"+leafCounter,leafCounter,{_x:Math.random()*Stage.width,_y:Math.random()*Stage.height,_rotation:Math.random()*360}); //adds a leaf to rthe stage with a random position and random rotation leafCounter++; //adds 1 to the leaf counter counter.textbox.text = leafCounter; //shows that number in the text box } I'm sure it must be a simple error, I can get the logic working when it just traces something on the screen but i can't get it to generate an "enemy" Any help or hints would be really useful! I know this is a bit of a ham-fisted job of altering existing code.

  • Launching an Activity from a Service

    - by nldev
    When I am trying to launch a call activity from a Service, I get a NullPointerException.

  • Using my custom colormap in Java for images

    - by John
    Hi everyone! I've got a question concering a colormapping via index. I tried this code found on http://www.podgoretsky.pri.ee/ftp/Docs/Java/Tricks%20of%20the%20Java%20Programming%20Gurus/ch12.htm // Gradient.java // Imports import java.applet.Applet; import java.awt.; import java.awt.image.; public class Gradient extends Applet { final int colors = 32; final int width = 200; final int height = 200; Image img; public void init() { // Create the color map byte[] rbmap = new byte[colors]; byte[] gmap = new byte[colors]; for (int i = 0; i < colors; i++) gmap[i] = (byte)((i * 255) / (colors - 1)); // Create the color model int bits = (int)Math.ceil(Math.log(colors) / Math.log(2)); IndexColorModel model = new IndexColorModel(bits, colors, rbmap, gmap, rbmap); // Create the pixels int pixels[] = new int[width * height]; int index = 0; for (int y = 0; y < height; y++) for (int x = 0; x < width; x++) pixels[index++] = (x * colors) / width; // Create the image img = createImage(new MemoryImageSource(width, height, model, pixels, 0, width)); } public void paint(Graphics g) { g.drawImage(img, 0, 0, this); } } It worked great but I tried to load a custom image jpeg mapped on my own colormap but it didnt work right. I saw only a bunch of green and blue pixels drawn on a white background. My custom color map method here: public void inintByteArrays() { double[][] c = // basic color map { { 0.0000, 0.0000, 0.5625 }, { 0.0000, 0.0000, 0.6250 }, { 0.0000, 0.0000, 0.6875 }, { 0.0000, 0.0000, 0.6875 }, { 0.0000, 0.0000, 0.7500 }, { 0.0000, 0.0000, 0.8125 }, { 0.0000, 0.0000, 0.8750 }, { 0.0000, 0.0000, 0.9375 }, { 0.0000, 0.0000, 1.0000 }, { 0.0000, 0.0625, 1.0000 }, { 0.0000, 0.1250, 1.0000 }, { 0.0000, 0.1875, 1.0000 }, { 0.0000, 0.2500, 1.0000 }, { 0.0000, 0.3125, 1.0000 }, { 0.0000, 0.3750, 1.0000 }, { 0.0000, 0.4375, 1.0000 }, { 0.0000, 0.5000, 1.0000 }, { 0.0000, 0.5625, 1.0000 }, { 0.0000, 0.6250, 1.0000 }, { 0.0000, 0.6875, 1.0000 }, { 0.0000, 0.7500, 1.0000 }, { 0.0000, 0.8125, 1.0000 }, { 0.0000, 0.8750, 1.0000 }, { 0.0000, 0.9375, 1.0000 }, { 0.0000, 1.0000, 1.0000 }, { 0.0625, 1.0000, 0.9375 }, { 0.1250, 1.0000, 0.8750 }, { 0.1875, 1.0000, 0.8125 }, { 0.2500, 1.0000, 0.7500 }, { 0.3125, 1.0000, 0.6875 }, { 0.3750, 1.0000, 0.6250 }, { 0.4375, 1.0000, 0.5625 }, { 0.5000, 1.0000, 0.5000 }, { 0.5625, 1.0000, 0.4375 }, { 0.6250, 1.0000, 0.3750 }, { 0.6875, 1.0000, 0.3125 }, { 0.7500, 1.0000, 0.2500 }, { 0.8125, 1.0000, 0.1875 }, { 0.8750, 1.0000, 0.1250 }, { 0.9375, 1.0000, 0.0625 }, { 1.0000, 1.0000, 0.0000 }, { 1.0000, 0.9375, 0.0000 }, { 1.0000, 0.8750, 0.0000 }, { 1.0000, 0.8125, 0.0000 }, { 1.0000, 0.7500, 0.0000 }, { 1.0000, 0.6875, 0.0000 }, { 1.0000, 0.6250, 0.0000 }, { 1.0000, 0.5625, 0.0000 }, { 1.0000, 0.5000, 0.0000 }, { 1.0000, 0.4375, 0.0000 }, { 1.0000, 0.3750, 0.0000 }, { 1.0000, 0.3125, 0.0000 }, { 1.0000, 0.2500, 0.0000 }, { 1.0000, 0.1875, 0.0000 }, { 1.0000, 0.1250, 0.0000 }, { 1.0000, 0.0625, 0.0000 }, { 1.0000, 0.0000, 0.0000 }, { 0.9375, 0.0000, 0.0000 }, { 0.8750, 0.0000, 0.0000 }, { 0.8125, 0.0000, 0.0000 }, { 0.7500, 0.0000, 0.0000 }, { 0.6875, 0.0000, 0.0000 }, { 0.6250, 0.0000, 0.0000 }, { 0.5625, 0.0000, 0.0000 }, { 0.5000, 0.0000, 0.0000 } }; for (int i = 0; i < c.length; i++) { for (int j = 0; j < c[i].length; j++) { if (j == 0) r[i] = (byte) ((byte) c[i][j]*255); if (j == 1) g[i] = (byte) ((byte) c[i][j]*255); if (j == 2) b[i] = (byte) ((byte) c[i][j]*255); } } My question is how I can use my colormap for any image I want to load and map in the right way.

  • JDBC Lock a row using SELECT FOR UPDATE, doesn't work

    - by Rachid
    I am having issues with MySQL's SELECT .. FOR UPDATE, here is the query I am trying to run: SELECT * FROM tableName WHERE HostName='UnknownHost' ORDER BY UpdateTimestamp asc limit 1 FOR UPDATE After this, the concerned thread will do an UPDATE and change the HostName, which is then it should unlock the row. I am running a multi-threaded java application, so 3 threads are running this SQL statement, but when thread 1 runs this, it doesn't lock its results from thread 2 & 3. Therefore threads 2 & 3 are getting the same results and they could update the same row. Also each thread is on its own mysql connection.

  • replaceAll() method using parameter from text file

    - by Herman Plani Ginting
    i have a collection of raw text in a table in database, i need to replace some words in this collection using a set of words. i put all the term to be replace and its substitutes in a text file as below min=admin lelet=lambat lemot=lambat nii=nih ntu=itu and so on. i have successfully initiate a variabel of File and Scanner to read the collection of the term and its substitutes. i loop all the dataset and save the raw text in a string in the same loop i loop all the term collection and save its row to a string name 'pattern', and split the pattern into two string named 'term' and 'replacer' in this loop i initiate a new string which its value is the string from the dataset modified by replaceAll(term,replacer) end loop for term collection then i insert the new string to another table in database end loop for dataset i do it manualy as below replaceAll("min","admin") and its works but its really something to code it manually for almost 2000 terms to be replace it. anyone ever face this kind of really something.. i really need a help now desperate :( package sentimenrepo; import javax.swing.*; import java.sql.*; import java.io.*; //import java.util.HashMap; import java.util.Scanner; //import java.util.Map; /** * * @author herman */ public class synonimReplaceV2 extends SwingWorker { protected Object doInBackground() throws Exception { new skripsisentimen.sentimenttwitter().setVisible(true); Integer row = 0; File synonimV2 = new File("synV2/catatan_kata_sinonim.txt"); String newTweet = ""; DB db = new DB(); Connection conn = db.dbConnect("jdbc:mysql://localhost:3306/tweet", "root", ""); try{ Statement select = conn.createStatement(); select.executeQuery("select * from synonimtweet"); ResultSet RS = select.getResultSet(); Scanner scSynV2 = new Scanner(synonimV2); while(RS.next()){ row++; String no = RS.getString("no"); String tweet = " "+ RS.getString("tweet"); String published = RS.getString("published"); String label = RS.getString("label"); clean2 cleanv2 = new clean2(); newTweet = cleanv2.cleanTweet(tweet); try{ Statement insert = conn.createStatement(); insert.executeUpdate("INSERT INTO synonimtweet_v2(no,tweet,published,label) values('" +no+"','"+newTweet+"','"+published+"','"+label+"')"); String current = skripsisentimen.sentimenttwitter.txtAreaResult.getText(); skripsisentimen.sentimenttwitter.txtAreaResult.setText(current+"\n"+row+"original : "+tweet+"\n"+newTweet+"\n______________________\n"); skripsisentimen.sentimenttwitter.lblStat.setText(row+" tweet read"); skripsisentimen.sentimenttwitter.txtAreaResult.setCaretPosition(skripsisentimen.sentimenttwitter.txtAreaResult.getText().length() - 1); }catch(Exception e){ skripsisentimen.sentimenttwitter.lblStat.setText(e.getMessage()); } skripsisentimen.sentimenttwitter.lblStat.setText(e.getMessage()); } }catch(Exception e){ skripsisentimen.sentimenttwitter.lblStat.setText(e.getMessage()); } return row; } class clean2{ public clean2(){} public String cleanTweet(String tweet){ File synonimV2 = new File("synV2/catatan_kata_sinonim.txt"); String pattern = ""; String term = ""; String replacer = ""; String newTweet=""; try{ Scanner scSynV2 = new Scanner(synonimV2); while(scSynV2.hasNext()){ pattern = scSynV2.next(); term = pattern.split("=")[0]; replacer = pattern.split("=")[1]; newTweet = tweet.replace(term, replacer); } }catch(Exception e){ e.printStackTrace(); } System.out.println(newTweet+"\n"+tweet); return newTweet; } } }

  • What's my best approach on this simple hierarchy Java Problem?

    - by Nazgulled
    First, I'm sorry for the question title but I can't think of a better one to describe my problem. Feel free to change it :) Let's say I have this abstract class Box which implements a couple of constructors, methods and whatever on some private variables. Then I have a couple of sub classes like BoxA and BoxB. Both of these implement extra things. Now I have another abstract class Shape and a few sub classes like Square and Circle. For both BoxA and BoxB I need to have a list of Shape objects but I need to make sure that only Square objects go into BoxA's list and only Circle objects go into BoxB's list. For that list (on each box), I need to have a get() and set() method and also a addShape() and removeShape() methods. Another important thing to know is that for each box created, either BoxA or BoxB, each respectively Shape list is exactly the same. Let's say I create a list of Square's named ls and two BoxA objects named boxA1 and boxA2. No matter what, both boxA1 and boxA2 must have the same ls list. This is my idea: public abstract class Box { // private instance variables public Box() { // constructor stuff } // public instance methods } public class BoxA extends Box { // private instance variables private static List<Shape> list; public BoxA() { // constructor stuff } // public instance methods public static List<Square> getList() { List<Square> aux = new ArrayList<Square>(); for(Square s : list.values()) { aux.add(s.clone()); // I know what I'm doing with this clone, don't worry about it } return aux; } public static void setList(List<Square> newList) { list = new ArrayList<Square>(newList); } public static void addShape(Square s) { list.add(s); } public static void removeShape(Square s) { list.remove(list.indexOf(s)); } } As the list needs to be the same for that type of object, I declared as static and all methods that work with that list are also static. Now, for BoxB the class would be almost the same regarding the list stuff. I would only replace Square by Triangle and the problem was solved. So, for each BoxA object created, the list would be only one and the same for each BoxB object created, but a different type of list of course. So, what's my problem you ask? Well, I don't like the code... The getList(), setList(), addShape() and removeShape() methods are basically repeated for BoxA and BoxB, only the type of the objects that the list will hold is different. I can't think of way to do it in the super class Box instead. Doing it statically too, using Shape instead of Square and Triangle, wouldn't work because the list would be only one and I need it to be only one but for each sub class of Box. How could I do this differently and better? P.S: I could not describe my real example because I don't know the correct words in English for the stuff I'm doing, so I just used a box and shapes example, but it's basically the same.

  • Need help with writing from XML to a SQL Server database (detailed)

    - by fogedi
    I'm a bit of a newbie with XML and WebServices and stuff like that. I'm working on a project using GlassFish OpenESB to schedule a process to get some information from a webservice and then store in a database. The criteria is basically that i have to use GlassFish OpenESB or EJB modules where i can expose webservices or something along those lines, AND i have to use SQL Server 2005. So far I've been able to talk to the webservice: and receive something along those lines <?xml version="1.0" encoding="UTF-8" standalone="no"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://schemas.xmlsoap.org/soap/envelope/ http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Body> <m:entrypoint_getSettlementsOperationResponse xmlns:m="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <part1> <GetSettlementsByMerchantResponse xmlns="http://Borgun.Services.Gateway/2010/04/Settlement"> <GetSettlementsByMerchantResult xmlns:a="http://schemas.datacontract.org/2004/07/Borgun.Library.Common" xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:msgns="http://Borgun.Services.Gateway/2010/04/Settlement" xmlns:ns0="http://j2ee.netbeans.org/wsdl/BorgunTestBPEL/entrypoint_getSettlements"> <a:CreditCardSettlement> <a:amexAmount>XXX</a:amexAmount> <a:amount>XXXX</a:amount> <a:batches> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>XXXX</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xx4</a:settlementRunNumber> <a:settlementdate>2010-04-06T00:00:00</a:settlementdate> <a:slips>2</a:slips> <a:sum>xxxx</a:sum> </a:CreditCardBatch> <a:CreditCardBatch> <a:batchdate>xxx</a:batchdate> <a:batchnumber>xxxxx</a:batchnumber> <a:currencyCode>xxxx</a:currencyCode> <a:merchantnumber>xxxx</a:merchantnumber> <a:settlementRunNumber>xxxx</a:settlementRunNumber> <a:settlementdate>xxxx</a:settlementdate> <a:slips>x</a:slips> <a:sum>xxx</a:sum> </a:CreditCardBatch> </a:batches> <a:commission>xx</a:commission> <a:currencyCode>xxx</a:currencyCode> <a:deduction>-xxx</a:deduction> <a:deductionItems> <a:CrediCardSettlementDeduction> <a:amount>-xxx</a:amount> <a:code>VIÐSKF</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>Afsláttur v/ekorta</a:text> </a:CrediCardSettlementDeduction> <a:CrediCardSettlementDeduction> <a:amount>-335.00</a:amount> <a:code>ÁLAGKREK</a:code> <a:currencyCode>ISK</a:currencyCode> <a:merchantnumber>xxx</a:merchantnumber> <a:settlementrunnumber>xxx</a:settlementrunnumber> <a:text>xxx</a:text> </a:CrediCardSettlementDeduction> </a:deductionItems> </a:CreditCardSettlement> </GetSettlementsByMerchantResult> </GetSettlementsByMerchantResponse> </part1> </m:entrypoint_getSettlementsOperationResponse> </SOAP-ENV:Body> </SOAP-ENV:Envelope> I have access to the SQL Server 2005 server which is remote and i know i can insert into it but given that now i have a one-to-many relationship i want to be able to rollback if something fails. So in short how can I insert from this XML into the DB preferably without manually walking through the XML tree? I'm pretty sure I'm supposed to be able to use Entity and Session Beans or maybe JAXB bindings but I'm simply not being successful. One of the reasons might have something to do with the fact that the soap response contains an array of CreditCardSettlements and each of which contains an array of Batches and DeductionItems It would be best if someone can help me do this via a BPEL in GlassFish OpenESB but any hint at a java solution is much appreciated.

  • Draw Circle on the Map once the application gets loaded

    - by TechGeeky
    Background:- In my application what is happening currently- Whenever I am opening the application, In the top half of the android screen, it draws a Map and in the bottom half of the android screen it show's a list view. And then as soon as the location gets changed, it draw's a Circle with the current location as the center of the circle and show's an image at the current location(center of circle). Everything is working fine till here- Problem Statement:- What I want is when the user opens my application, circle should get draw immediately on the Google Map (this is currently not happening, it draw's circle only on the location changed), without waiting for the location to get changed and without any image on the center of circle and then if the location get's changed, take the current location as the center of circle and draw the circle with an image at the center of circle. And this is my below code which fulfills the scenario that I mentioned in my Background- How can I make this code to work the way I wanted to? hope I am clear enough in my question. Any suggestions will be appreciated. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mapView = (MapView) findViewById(R.id.mapView); listView = (ListView) findViewById(R.id.mylist); locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationListener = new GPSLocationListener(mapView); locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 35000, 10, locationListener); mapView.setStreetView(true); mapView.setBuiltInZoomControls(true); mapController = mapView.getController(); mapController.setZoom(14); } Location Update class where I am sending the request to Overlay to draw the circle private class GPSLocationListener implements LocationListener { MapOverlay mapOverlay; public GPSLocationListener(MapView mapView) { } @Override public void onLocationChanged(Location location) { if (location != null) { GeoPoint point = new GeoPoint( (int) (location.getLatitude() * 1E6), (int) (location.getLongitude() * 1E6)); mapController.animateTo(point); mapController.setZoom(15); if (mapOverlay == null) { mapOverlay = new MapOverlay(this,android.R.drawable.star_on); List<Overlay> listOfOverlays = mapView.getOverlays(); listOfOverlays.add(mapOverlay); } mapOverlay.setPointToDraw(point); mapView.invalidate(); } } @Override public void onProviderDisabled(String provider) { } @Override public void onProviderEnabled(String provider) { } @Override public void onStatusChanged(String provider, int status, Bundle extras) { } } Class in which circle is getting drawn. class MapOverlay extends Overlay { private GeoPoint pointToDraw; int[] imageNames=new int[6]; private Point mScreenPoints; private Bitmap mBitmap; private Paint mCirclePaint; public MapOverlay(GPSLocationListener gpsLocationListener, int currentUser) { imageNames[0]=currentUser; mCirclePaint = new Paint(Paint.ANTI_ALIAS_FLAG); mCirclePaint.setColor(0x30000000); mCirclePaint.setStyle(Style.FILL_AND_STROKE); mBitmap = BitmapFactory.decodeResource(getResources(),imageNames[0]); mScreenPoints = new Point(); } public void setPointToDraw(GeoPoint point) { pointToDraw = point; } public GeoPoint getPointToDraw() { return pointToDraw; } @Override public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { super.draw(canvas, mapView, shadow); if (pointToDraw == null) { return true; } mScreenPoints = mapView.getProjection().toPixels(pointToDraw, mScreenPoints); int totalCircle=5; int radius=40; int centerimagesize=35; for (int i = 1; i <= totalCircle; i ++) { canvas.drawCircle(mScreenPoints.x,mScreenPoints.y, i*radius, mCirclePaint); } canvas.drawBitmap(mBitmap, (mScreenPoints.x-(centerimagesize/2)),(mScreenPoints.y-(centerimagesize/2)), null); super.draw(canvas,mapView,shadow); return true; } }

Using the code below I can successfully authenticate a user from test1 but not on test2: public class ADDetailsProvider implements ResultSetProvider { private String domain; private String user; private String password; public ADDetailsProvider(String user, String password) { //extract domain name if (user.contains("\\")) { this.user = user.substring((user.lastIndexOf("\\") + 1), user.length()); this.domain = user.substring(0, user.lastIndexOf("\\")); } else { this.user = user; this.domain = ""; } this.password = password; } /* Test from the command line */ public static void main (String[] argv) throws SQLException { ResultSetProvider res = processADLogin(argv[0], argv[1]); ResultSet results = null; res.assignRowValues(results, 0); System.out.println(argv[0] + " " + argv[1]); } public boolean assignRowValues(ResultSet results, int currentRow) throws SQLException { // Only want a single row if (currentRow >= 1) return false; try { ADAuthenticator adAuth = new ADAuthenticator(); LdapContext ldapCtx = adAuth.authenticate(this.domain, this.user, this.password); NamingEnumeration userDetails = adAuth.getUserDetails(ldapCtx, this.user); // Fill the result set (throws SQLException). while (userDetails.hasMoreElements()) { Attribute attr = (Attribute)userDetails.next(); results.updateString(attr.getID(), attr.get().toString()); } results.updateInt("authenticated", 1); return true; } catch (FileNotFoundException fnf) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught File Not Found Exception trying to read cris_authentication.properties"); results.updateInt("authenticated", 0); return false; } catch (IOException ioe) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught IO Excpetion processing login"); results.updateInt("authenticated", 0); return false; } catch (AuthenticationException aex) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught Authentication Exception attempting to bind to LDAP for [{0}]", this.user); results.updateInt("authenticated", 0); return true; } catch (NamingException ne) { Logger.getAnonymousLogger().log(Level.WARNING, "Caught Naming Exception performing user search or LDAP bind for [{0}]", this.user); results.updateInt("authenticated", 0); return true; } } public void close() { // nothing needed here } /** * This method is called via a Postgres function binding to access the * functionality provided by this class. */ public static ResultSetProvider processADLogin(String user, String password) { return new ADDetailsProvider(user, password); } } public class ADAuthenticator { public ADAuthenticator() throws FileNotFoundException, IOException { Properties props = new Properties(); InputStream inStream = this.getClass().getClassLoader(). getResourceAsStream("com/bar/foo/ad/authentication.properties"); props.load(inStream); this.domain = props.getProperty("ldap.domain"); inStream.close(); } public LdapContext authenticate(String domain, String user, String pass) throws AuthenticationException, NamingException, IOException { Hashtable env = new Hashtable(); this.domain = domain; env.put(Context.INITIAL_CONTEXT_FACTORY, com.sun.jndi.ldap.LdapCtxFactory); env.put(Context.PROVIDER_URL, "ldap://" + test1.ad1.foo.com + ":" + 3268); env.put(Context.SECURITY_AUTHENTICATION, simple); env.put(Context.REFERRAL, follow); env.put(Context.SECURITY_PRINCIPAL, (domain + "\\" + user)); env.put(Context.SECURITY_CREDENTIALS, pass); // Bind using specified username and password LdapContext ldapCtx = new InitialLdapContext(env, null); return ldapCtx; } public NamingEnumeration getUserDetails(LdapContext ldapCtx, String user) throws NamingException { // List of attributes to return from LDAP query String returnAttributes[] = {"ou", "sAMAccountName", "givenName", "sn", "memberOf"}; //Create the search controls SearchControls searchCtls = new SearchControls(); searchCtls.setReturningAttributes(returnAttributes); //Specify the search scope searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE); // Specify the user to search against String searchFilter = "(&(objectClass=*)(sAMAccountName=" + user + "))"; //Perform the search NamingEnumeration answer = ldapCtx.search("dc=dev4,dc=dbt,dc=ukhealth,dc=local", searchFilter, searchCtls); // Only care about the first tuple Attributes userAttributes = ((SearchResult)answer.next()).getAttributes(); if (userAttributes.size() <= 0) throw new NamingException(); return (NamingEnumeration) userAttributes.getAll(); } From what I understand of the trust relationship, if trust1 receives a login attempt for a user in trust2, then it should forward the login attempt on to it and it works this out from the user's domain name. Is this correct or am I missing something or is this not possible using the method above? --EDIT-- The stack trace from the LDAP bind is {java.naming.provider.url=ldap://test1.ad1.foo.com:3268, java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory, java.naming.security.authentication=simple, java.naming.referral=follow} 30-Oct-2012 13:16:02 ADDetailsProvider assignRowValues WARNING: Caught Authentication Exception attempting to bind to LDAP for [trusttest] Auth error is [LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db0]
