Embedding BI Call username password and dashboard parameters from CDE dashobard URL using iframe tags
A small workout on Embedding BI using Pentaho CDE dashboards..
Version Specific :
BA server : 5.1.0 stable CE
C-Tools : CDE,CDA,CDF of latest TRUNK version (after 14.x)
Steps :
1) Open your dashboard in new window to generate the URL
2) For instance the URL is some thing similar as shown below
URL when you open in new window
http://localhost:8085/pentaho/api/repos/:public:Explore:CDEExploring:Test:passParametersFromURL.wcdf/generatedContent
URL after adding BA Server Username and Password as parameters
http://localhost:8085/pentaho/api/repos/:public:Explore:CDEExploring:Test:passParametersFromURL.wcdf/generatedContent?userid=admin&password=password
URL after adding Dashboard parameters along with BA server credentials as parameters
http://localhost:8085/pentaho/api/repos/:public:Explore:CDEExploring:Test:passParametersFromURL.wcdf/generatedContent?userid=admin&password=password¶m1_deptId=100¶m2_Date=01/04/2014
Here you need to take custom parameters instead of Simple parameters.
i.e.,
For example :
param1_deptId is the custom parameter and in the java script area you need to write below code
function sendParam(){
return Dashboards.getQueryParameter("param1_deptId");
}
In another case of passing parameter like date type
param2_Date is the custom parameter and in the java script area you need to write below code
function sendParam(){
return Dashboards.getQueryParameter("param2_Date");
}
You need to add these parameters to your chart and query
For chart :
Parameters : param1_deptId,param2_Date
Listners : param1_deptId,param2_Date
For query :
Parameters: param1_deptId (String Type)
param2_Date(String Type)
Sample Query in Oracle SQL where clause for the above scenario :
where
to_char(column1_deptId)=${param1_deptId}
AND
to_char(column2_date(+),mm/dd/yyyy) =${param2_Date}
note that in the above clause (+) indicates in right outer join Oracle 10g
NOTE: You can pass multiple general parameters by adding ¶mName=value in the URL
3) Copy paste the URL in the web browser and test.. You will find the dashboard output directly.
Imp Note :
URL passing mechanism in BA server 5 is slightly differ from previous versions.
As suggested in jira for pentaho 5 server, you need to modify applicationContext-spring-security.xml under pentaho-solutions/system
Change 1 : at line 22
Original Code :
/api/**=securityContextHolderAwareRequestFilterForWS,httpSessionPentahoSessionContextIntegrationFilter,httpSessionContextIntegrationFilter,basicProcessingFilter,anonymousProcessingFilter,exceptionTranslationFilterForWS,filterInvocationInterceptorForWS
Replace the Original Code with :

Creating a Pentomino game using AS3 Part 38
Today we will add the ability to browse through the solutions.
Firstly declare a new variable - currentSol. Set its value to 0 by default. This variable represents the id of the solution that is currently displayed.
Open the project in Flash and go to fifth frame (the solutions screen). Add two buttons shaped like arrows with ids btn_prev and btn_next. Add a dynamic text field with id tSol, it will display which solutions is currently is shown.
Go to level_solver.as again and in the solve() function add CLICK event listeners for btn_prev and btn_next. Set handlers to goPrev and goNext functions:
The functions decrease/increase currentSol values and call updateCurrentInfo() function.
The same function is called in nextCycle():
The function updates what is displayed in the tSol text field, disables/enables arrow buttons when needed, draws the preview image:
Update the drawPreview() function so that cells are colored depending on the shape type:
Now we can browse through the solutions!

Firstly declare a new variable - currentSol. Set its value to 0 by default. This variable represents the id of the solution that is currently displayed.
private var currentSol:int = 0;
Open the project in Flash and go to fifth frame (the solutions screen). Add two buttons shaped like arrows with ids btn_prev and btn_next. Add a dynamic text field with id tSol, it will display which solutions is currently is shown.
Go to level_solver.as again and in the solve() function add CLICK event listeners for btn_prev and btn_next. Set handlers to goPrev and goNext functions:
btn_prev.addEventListener(MouseEvent.CLICK, goPrev);
btn_next.addEventListener(MouseEvent.CLICK, goNext);
The functions decrease/increase currentSol values and call updateCurrentInfo() function.
private function goPrev(evt:MouseEvent):void {
currentSol--;
updateCurrentInfo();
}
private function goNext(evt:MouseEvent):void {
currentSol++;
updateCurrentInfo();
}
The same function is called in nextCycle():
private function nextCycle():void {
cycleNum++;
updateCurrentInfo();
if (cycleNum == givenShapes.length) {
removeEventListener(Event.ENTER_FRAME, onFrame);
// display info
tInfo.text = Finished solving " + levelName + "
Attempts: + attempts + "
Solutions: " + solutions.length;
}
}
The function updates what is displayed in the tSol text field, disables/enables arrow buttons when needed, draws the preview image:
private function updateCurrentInfo():void {
var sol:int = (solutions.length > 0)?(currentSol + 1):(0);
tSol.text = sol + "/" + solutions.length;
if (sol <= 1) {
btn_prev.alpha = 0.5;
btn_prev.mouseEnabled = false;
}else {
btn_prev.alpha = 1;
btn_prev.mouseEnabled = true;
}
if (sol == solutions.length) {
btn_next.alpha = 0.5;
btn_next.mouseEnabled = false;
}else {
btn_next.alpha = 1;
btn_next.mouseEnabled = true;
}
if (solutions.length > 0) drawPreview(levelPreview, solutions[currentSol]);
}
Update the drawPreview() function so that cells are colored depending on the shape type:
private function drawPreview(levelPreview:MovieClip, mapGrid:Array):void {
var columns:int = mapGrid[0].length;
var rows:int = mapGrid.length;
var frameWidth:int = levelPreview.width;
var frameHeight:int = levelPreview.height;
var padding:int = 5;
var fitWidth:int = levelPreview.width - (padding * 2);
var fitHeight:int = levelPreview.height - (padding * 2);
var gridStartX:int;
var gridStartY:int;
// calculate width of a cell:
var gridCellWidth:int = Math.round(fitWidth / columns);
var width:int = columns * gridCellWidth;
var height:int = rows * gridCellWidth;
// calculate side margin
gridStartX = (frameWidth - width) / 2;
if (height < fitHeight) {
gridStartY = (fitHeight - height) / 2;
}
if (height >= fitHeight) {
gridCellWidth = Math.round(fitHeight / rows);
height = rows * gridCellWidth;
width = columns * gridCellWidth;
gridStartY = (frameHeight - height) / 2;
gridStartX = (frameWidth - width) / 2;
}
// draw map
levelPreview.shape.x = gridStartX;
levelPreview.shape.y = gridStartY;
levelPreview.shape.graphics.clear();
var i:int;
var u:int;
for (i = 0; i < rows; i++) {
for (u = 0; u < columns; u++) {
if (mapGrid[i][u] == 1) drawCell(u, i, 0xffffff, 1, 0x999999, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 2) drawCell(u, i, 0xff66cc, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 3) drawCell(u, i, 0x00FF66, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 4) drawCell(u, i, 0x99ff00, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 5) drawCell(u, i, 0x00ccff, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 6) drawCell(u, i, 0xffcc66, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 7) drawCell(u, i, 0x66cc33, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 8) drawCell(u, i, 0x9900ff, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 9) drawCell(u, i, 0xff5858, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 10) drawCell(u, i, 0xff6600, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 11) drawCell(u, i, 0x00ffff, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 12) drawCell(u, i, 0xff6b20, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 13) drawCell(u, i, 0xffff66, 1, 0x000000, gridCellWidth, levelPreview.shape);

Now we can browse through the solutions!

or Creating a Pentomino game using AS3 Part 9
Today well improve our shape placing code, as well as make all shapes available for placing.
First of all, well create a function that draws a preview of where the shape will be placed exactly. We need to declare a new Sprite object for this - canPutShape:
And add it to the stage after creating the grid:
The function uses some of the already used code in the script, slightly modified. We simply loop through the currentValues and draw each cell:
Now go to mouseMove() and instead of the selectedShape if statement call a function called checkPut():
The functions code is the same, but has a few modifications. We check if canPutHere is tru or false and set the cursors alpha to represent whether its possible or not to place the selected shape here. We also clear canPutShapes graphics if canPutHere is false.
Where is drawCanPut() called if not in checkPut(), you ask? Thats in updateCurrentValues(), but only after weve added a few modifications to the code inside updateCurrentValues(). These bugs were found after I implemented the "shadow" feature thats drawn by drawCanPut(), and you can see the updated code below:
Call checkPut() instead of updateCurrentValues() in mouseWheel() and keyDown():
Now we can update the shapeValues() array. Simply add each shape cells relative coordinates:
And full code so far:

First of all, well create a function that draws a preview of where the shape will be placed exactly. We need to declare a new Sprite object for this - canPutShape:
private var canPutShape:Sprite = new Sprite();
And add it to the stage after creating the grid:
// can put shape
addChild(canPutShape);
canPutShape.x = gridStartX;
canPutShape.y = gridStartY;
The function uses some of the already used code in the script, slightly modified. We simply loop through the currentValues and draw each cell:
private function drawCanPut():void {
canPutShape.graphics.clear();
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = (currentValues[i][0] + mousePos.x) * gridCellWidth;
var cellY:int = (currentValues[i][1] + mousePos.y) * gridCellWidth;
canPutShape.graphics.beginFill(0x00ff00, 0.1);
canPutShape.graphics.drawRect(cellX, cellY, gridCellWidth, gridCellWidth);
}
}
Now go to mouseMove() and instead of the selectedShape if statement call a function called checkPut():
private function mouseMove(evt:MouseEvent):void {
cursor.x = mouseX;
cursor.y = mouseY;
checkPut();
}
The functions code is the same, but has a few modifications. We check if canPutHere is tru or false and set the cursors alpha to represent whether its possible or not to place the selected shape here. We also clear canPutShapes graphics if canPutHere is false.
private function checkPut():void {
if (selectedShape > 0) {
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
canPutHere = true;
updateCurrentValues();
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = currentValues[i][0] + mousePos.x;
var cellY:int = currentValues[i][1] + mousePos.y;
if (cellX < 0 || cellY < 0 || cellX >= mapGrid[0].length || cellY >= mapGrid.length || mapGrid[cellY][cellX]!=1) {
canPutHere = false;
}
}
if (canPutHere) {
cursor.alpha = 0.8;
}
if (!canPutHere) {
canPutShape.graphics.clear();
cursor.alpha = 0.4;
}
}
}
Where is drawCanPut() called if not in checkPut(), you ask? Thats in updateCurrentValues(), but only after weve added a few modifications to the code inside updateCurrentValues(). These bugs were found after I implemented the "shadow" feature thats drawn by drawCanPut(), and you can see the updated code below:
private function updateCurrentValues():void {
currentValues = clone(shapeValues[selectedShape-1]);
for (var i:int = 0; i < 5; i++) {
if (cursor.rotation == 90) {
currentValues[i].reverse();
currentValues[i][0] *= -1;
}
if (cursor.rotation == 180 || cursor.rotation == -180) {
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
if (cursor.rotation == -90) {
currentValues[i].reverse();
currentValues[i][1] *= -1;
}
if (cursor.scaleX < 0 && (cursor.rotation != -90 || cursor.rotation != 90)) {
currentValues[i][0] *= -1;
}
if (cursor.scaleX < 0 && (cursor.rotation == -90 || cursor.rotation == 90)) {
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
}
drawCanPut();
}
Call checkPut() instead of updateCurrentValues() in mouseWheel() and keyDown():
private function mouseWheel(evt:MouseEvent):void {
if (evt.delta > 0) cursor.rotation += 90;
if (evt.delta < 0) cursor.rotation -= 90;
if (selectedShape > 0) checkPut();
}
private function keyDown(evt:KeyboardEvent):void {
if (evt.keyCode == 68) cursor.rotation += 90;
if (evt.keyCode == 65) cursor.rotation -= 90;
if (evt.keyCode == 32) cursor.scaleX *= -1;
if (selectedShape > 0) checkPut();
}
Now we can update the shapeValues() array. Simply add each shape cells relative coordinates:
shapeValues = [
[[0, 0], [0, 1], [0, 2], [0, -1], [0, -2]],
[[0, 0], [0, -1], [0, 1], [1, 0], [1, -1]],
[[0, 0], [0, 1], [0, 2], [0, -1], [ -1, -1]],
[[0, 0], [0, 1], [0, -1], [ -1, 0], [1, -1]],
[[0, 0], [ -1, 0], [ -2, 0], [0, -1], [1, -1]],
[[0, 0], [0, 1], [0, -1], [1, -1], [ -1, -1]],
[[0, 0], [1, 0], [ -1, 0], [1, -1], [ -1, -1]],
[[0, 0], [ -1, 0], [ -2, 0], [0, -1], [0, -2]],
[[0, 0], [0, 1], [ -1, 1], [1, 0], [1, -1]],
[[0, 0], [0, 1], [0, -1], [1, 0], [ -1, 0]],
[[0, 0], [ -1, 0], [ -2, 0], [1, 0], [0, -1]],
[[0, 0], [0, 1], [1, 1], [0, -1], [-1, -1]]
];

Creating a Pentomino game using AS3 Part 8
In this part we will add the ability to place rotated shape on the grid.
In the previous tutorials we used internal (temporary) variable inside several functions named currentValues. Lets make this a private variable available in all functions:
So in mouseMove(), instead of setting value to this variable we call updateCurrentValues():
Call the same function in mouseWheel and keyDown if there is a shape thats selected:
Go to mouseUp() and add a line that sets the new shapes rotation to cursor.rotation:
Now create a new function called clone(). This will be used to clone an array with arrays inside of it properly:
Add updateCurrentValues() function. Here in the first line we clone the respective element in shapeValues and apply that value to currentValues.
Then we loop through all the 5 elemenst of it, and go through a few if statements to modify the values. If cursors rotation is 0, we dont need to change anything, since the values in currentValues apply here. If the shape has rotation 90, we need to reverse the values of each element (x becomes y and y becomes x). If the rotation is 180 or -180, we inverse the values by multiplying them by -1. If the rotation is -90, inverse and reverse the values. If scaleX of cursor is less than 0, inverse the X values:
Now we can drag, rotate, and drop the first shape properly.
Full code so far:
Next time well implement more shapes.

In the previous tutorials we used internal (temporary) variable inside several functions named currentValues. Lets make this a private variable available in all functions:
private var currentValues:Array = [];
So in mouseMove(), instead of setting value to this variable we call updateCurrentValues():
private function mouseMove(evt:MouseEvent):void {
cursor.x = mouseX;
cursor.y = mouseY;
if (selectedShape > 0) {
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
canPutHere = true;
updateCurrentValues();
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = currentValues[i][0] + mousePos.x;
var cellY:int = currentValues[i][1] + mousePos.y;
if (cellX < 0 || cellY < 0 || cellX >= mapGrid[0].length || cellY >= mapGrid.length || mapGrid[cellY][cellX]!=1) {
canPutHere = false;
}
}
}
}
Call the same function in mouseWheel and keyDown if there is a shape thats selected:
private function mouseWheel(evt:MouseEvent):void {
if (evt.delta > 0) cursor.rotation += 90;
if (evt.delta < 0) cursor.rotation -= 90;
if (selectedShape > 0) updateCurrentValues();
}
private function keyDown(evt:KeyboardEvent):void {
if (evt.keyCode == 68) cursor.rotation += 90;
if (evt.keyCode == 65) cursor.rotation -= 90;
if (evt.keyCode == 32) cursor.scaleX *= -1;
if (selectedShape > 0) updateCurrentValues();
}
Go to mouseUp() and add a line that sets the new shapes rotation to cursor.rotation:
private function mouseUp(evt:MouseEvent):void {
stopDragShape();
if (selectedShape > 0) {
if (!canPutHere) {
availableShapes[selectedShape-1]++;
shapeButtons[selectedShape-1].count.text = availableShapes[selectedShape-1];
selectedShape = 0;
}
if (canPutHere) {
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
var newShape:MovieClip = new game_shape();
addChild(newShape);
newShape.x = gridStartX + (mousePos.x+1) * gridCellWidth - gridCellWidth / 2;
newShape.y = gridStartY + (mousePos.y + 1) * gridCellWidth - gridCellWidth / 2;
newShape.rotation = cursor.rotation;
newShape.scaleX = cursor.scaleX;
newShape.scaleY = cursor.scaleY;
newShape.gotoAndStop(selectedShape);
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = currentValues[i][0] + mousePos.x;
var cellY:int = currentValues[i][1] + mousePos.y;
mapGrid[cellY][cellX] = 2;
}
cursor.parent.setChildIndex(cursor, cursor.parent.numChildren - 1);
selectedShape = 0;
}
}
}
Now create a new function called clone(). This will be used to clone an array with arrays inside of it properly:
private function clone(source:Object):*{
var myBA:ByteArray = new ByteArray();
myBA.writeObject(source);
myBA.position = 0;
return(myBA.readObject());
}
Add updateCurrentValues() function. Here in the first line we clone the respective element in shapeValues and apply that value to currentValues.
Then we loop through all the 5 elemenst of it, and go through a few if statements to modify the values. If cursors rotation is 0, we dont need to change anything, since the values in currentValues apply here. If the shape has rotation 90, we need to reverse the values of each element (x becomes y and y becomes x). If the rotation is 180 or -180, we inverse the values by multiplying them by -1. If the rotation is -90, inverse and reverse the values. If scaleX of cursor is less than 0, inverse the X values:
private function updateCurrentValues():void {
currentValues = clone(shapeValues[selectedShape-1]);
for (var i:int = 0; i < 5; i++) {
if (cursor.rotation == 90) currentValues[i].reverse();
if (cursor.rotation == 180 || cursor.rotation == -180) {
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
if (cursor.rotation == -90) {
currentValues[i].reverse();
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
if (cursor.scaleX < 0) {
currentValues[i][0] *= -1;
}
}
}
Now we can drag, rotate, and drop the first shape properly.
