java - fill select in struts2 -

-

I'm trying to fill my struts 2 with this method, but I have all these empty dropdowns. This is my verb method 

  private list & lt; String & gt; District List = New Array's & lt; String & gt; (); Public string get_DistrictList () {try {currentCon = ConnectionManager.getConnection ()); Statement stmt = (Statement) Present Con.createStatement (); Rs = stmt.executeQuery ("Select District_ID, district_name from district"); Whereas (rsnext ()) district list.ed (rsgetstring ("district_name")); DistrictList.add (rs.getString ("district_id")); } Hold (exception e) {System.out.println ("error from DAO:" + E); } Return Success; }   
 My JSP  
  & lt; S: Select label = "select district" id = "district_list" headerKey = "- 1" headerValue = "select district" list = "district list" list = "district_id" value = "district_name" tooltip = "select district" Name = "notarpos area" />   
 When I only add one district list & amp; & Amp; deleted list & amp; The list was working properly, but I want both keys and value in my selection. Is there any way?  
 Thank you in advance :)   
 
 
 You can do this  Map     Private map & lt; String, string & gt; DistrictMap; / ** Sets and gates / public string for mapping get_DistrictList () {districtMap = new Hashmop & lt; String, string & gt; (); try{ . . . While (rsnext ()) District map.put (rsgetstring ("district_name"), rsgetstring ("district_id")); . . } Hold (exception e) {System.out.println ("error from DAO:" + E); } Return Success; }   
 and  Generate Setter and Gates for the above map . And  
 in  JSP   
  
  & lt; S: Select label = "select district" id = "district_list" HeaderKey = "- 1" headerValue = "select the district" list = "districtmap" list = "key" list value = "value" tooltip = "select district" name = "Notepoos Distinct" />

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
