• options[Text] is null or not an object in javascript

  - by user9167

  I am getting options[text] is null or not an object error. What i am trying to do here is i am checking what all multi select lookup column values are selected , comparing them with the value in an array and then removing them var responsibleselected = returntags("select","Responsibility selected values"); for(var i=0;i<responsibleselected.options.length;i++) { if(responsibleselected.options[i].selected == true) { for(var j=0;j< ResponsibleArray.length;j++) { if(responsibleselected.options[i].text == ResponsibleArray[j])//throws error here { GipRemoveSelectedItems(ctl00_m_g_6ad915a8_68ea_4c76_b67a_ad1215320288_ff391_ctl00_ctl00_MultiLookupPicker_m); } } } }

• Manipulating a Storyboard's target object

  - by slugster

  In the handler for the Completed event of a Storyboard, how do i get the element that the storyboard was being applied to? My Storyboard is part of an ItemTemplate: <ListBox x:Name="MyListBox" > <ListBox.ItemTemplate> <DataTemplate> <Grid x:Name="Container" Height="30" > <Grid.Resources> <Storyboard x:Name="FadeOut" BeginTime="0:0:7" Completed="FadeOut_Completed"> <DoubleAnimation From="1.0" To="0.0" Duration="0:0:3" Storyboard.TargetName="Container" Storyboard.TargetProperty="Opacity" /> </Storyboard> </Grid.Resources> [...snip...] </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> in the Completed event i want to grab the grid called Container so that i can do nasty things with its DataContext. Can this be done, or am i going about it the wrong way? Thanks :)

• Reading Data from DDFS ValueError: No JSON object could be decoded

  - by secumind

  I'm running dozens of map reduce jobs for a number of different purposes using disco. My data has grown enormous and I thought I would try using DDFS for a change rather than standard txt files. I've followed the DISCO map/reduce example Counting Words as a map/reduce job, without to much difficulty and with the help of others, Reading JSON specific data into DISCO I've gotten past one of my latest problems. I'm trying to read data in/out of ddfs to better chunk and distribute it but am having a bit of trouble.

• Getting jQuery to return an ajax object

  - by japancheese

  Hello, The question title is a bit strange because I'm not exactly sure how to phrase the problem. The issue is that I have many links to which I want to bind a click event with an ajax call, and I'm just looking to refactor some duplicate code into a single area. The links I'm trying to bind an ajax call only have one thing that differentiates them, and that's an id from a previously declared object. So I have lots of code that looks like this: $("a.link").bind('click', function() { id = obj.id; $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); I was trying to refactor it into something like this: $("a.link").bind('click', ajax_link(obj.id)); function ajax_link(id) { $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); However, as you can imagine, this just actually makes the ajax call when the element is binded with the click event. Is there an easy way to refactor this code so I can extract out the common ajax code into its own function, and hopefully reduce the number of lines of jQuery in my current script?

• Stuck on Object scope in Java

  - by ivor

  Hello, I'm working my way through an exercise to understand Java, and basically I need to merge the functionality of two classes into one app. I'm stuck on one area though - the referencing of objects across classes. What I have done is set up a gui in one class (test1), and this has a textfield in ie. chatLine = new JTextField(); in another class(test2), I was planning on leaving all the functionality in there and referencing the various gui elements set up in test1 - like this test1.chatLine I understand this level of referencing, I tested this by setting up a test method in the test2 class public static void testpass() { test1.testfield.setText("hello"); } I'm trying to understand how to implement the more complex functionality in test2 class though, specifically this existing code; test1.chatLine.addActionListener(new ActionAdapter() { public void actionPerformed(ActionEvent e) { String s = Game.chatLine.getText(); if (!s.equals("")) { appendToChatBox("OUTGOING: " + s + "\n"); Game.chatLine.selectAll(); // Send the string sendString(s); } } }); This is the bit I'm stuck on, if I should be able to do this - as it's failing on the compile, can I add the actionadapter stuff to the gui element thats sat in test1, but do this from test2 - I'm wondering if I'm trying to do something that's not possible. Hope this makes sense, I'm pretty confused over this - I'm trying to understand how the scope and referencing works. Ideally what i'm trying to achieve is one class that has all the main stuff in, the gui etc, then all the related functionality in the other class, and target the first class's gui elements with the results etc. Any thoughts greatly appreciated.

• XML Serializing a class with a Dictionary<string, List<string>> object

  - by Matt

  Is it possible to implement IXmlSerializable and in my XML file capture an object of type Dictionary ? I have the following public class coolio : IXmlSerializable { private int a; private bool b; private string c; private Dictionary<string, List<string>> coco; public coolio(int _a, bool _b, string _c, Dictionary<string, List<string>> _coco) { a=_a; b=_b; c=_c; coco=_coco; } public System.Xml.Schema.XmlSchema GetSchema() { return null; } public void WriteXml(XmlWriter writer) { const string myType = "coolio"; writer.WriteStartElement(myType); writer.WriteAttributeString("a", a.ToString()); writer.WriteAttributeString("b", b.ToString()); writer.WriteAttributeString("c", c); // How do I add a subelement for Dictionary<string, List<string>> coco? writer.WriteEndElement(); } public void ReadXml(XmlReader reader) { if (reader.MoveToContent() != XmlNodeType.Element || reader.LocalName != "coolio") return; a= int.Parse(reader["a"]); b = bool.Parse(reader["b"]); c= reader["c"]; // How do I read subelement into Dictionary<string, List<string>> coco? } } But I am stumped as to how I could add the Dictionary (XML seriliazed to my XML file)

• targeting sprites from a method in the document class - null object reference

  - by Freddyk

  Hi I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched. Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'. //This code works because it can access 'e.target'. private function photo1SpriteFlickHandler(e:GestureEvent):void { var openTween:Tween = new Tween(e.target, "x", Strong.easeOut, 232, 970, 5, true); } //this code gives me a null object reference because I am using 'photo1Sprite' rather than 'e.target' private function photo1SpriteFlickHandler(e:GestureEvent):void { var openTween:Tween = new Tween(photo1Sprite, "x", Strong.easeOut, 232, 970, 5, true); } //photo1Sprite has already been programatically added to the screen as so: var photo1Sprite = new TouchSprite(); var photo1Loader=new Loader(); photo1Loader.load(new URLRequest("media/photos1/photo1.jpg")); photo1Loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loaderComplete); photo1Sprite.x = 232; photo1Sprite.y = 538; photo1Sprite.scaleX = .3; photo1Sprite.scaleY = .3; photo1Sprite.blobContainerEnabled = true; photo1Sprite.addEventListener(TouchEvent.TOUCH_DOWN, startDrag_Press); photo1Sprite.addEventListener(TouchEvent.TOUCH_UP, stopDrag_Release); photo1Sprite.addChild(photo1Loader); addChild(photo1Sprite); So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.

• NHibernate : Root collection with an root object

  - by Daniel

  Hi, I want to track a list of root objects which are not contained by any element. I want the following pseudo code to work: IList<FavoriteItem> list = session.Linq<FavoriteItem>().ToList(); list.Add(item1); list.Add(item2); list.Remove(item3); list.Remove(item4); var item5 = list.First(i => i.Name = "Foo"); item5.Name = "Bar"; session.Save(list); This should automatically insert item1 and item2, delete item3 and item3 and update item5 (i.e. I don't want to call sesssion.SaveOrUpdate() for all items separately. Is it possible to define a pseudo entity that is not associated with a table? For example I want to define the class Favorites and map 2 collection properties of it and than I want to write code like this: var favs = session.Linq<Favorites>(); favs.FavoriteColors.Add(new FavoriteColor(...)); favs.FavoriteMovies.Add(new FavoriteMovie(...)); session.SaveOrUpdate(favs); FavoriteColors and FavoriteMovies are the only properties of the Favorites class and are of type IList and IList. I do only want to persist the these two collection properties but not the Favorites class. Any help is much appreciated.

• Adding different objects to array, but only one object repeating

  - by Carpetfizz

  I have a small piece of PHP code that goes through valid values and fetches information about them. It then pushes it to an array. For some reason, I'm only getting the last item of $row, repeated several times. When I try to print_r at #1 in the code, the expected values are outputted. However, at the end of the loop, or outside of it, when I try to print_r($ipArray), I'm only getting the last value repeated multiple times. Any help would be much appreciated! while($row = mysqli_fetch_array($getIpQuery, MYSQLI_NUM)){ for($x=0;$x<count($row);$x++) { $getIpInfo = mysqli_query($dbcon, "SELECT * FROM ipInfo WHERE address='$row[$x]'"); $retrievedInfo = mysqli_fetch_array($getIpInfo, MYSQLI_NUM); $ipInfo->ipAddress = $retrievedInfo[0]; $ipInfo->portNum = $retrievedInfo[1]; print_r($ipInfo); //#1: Works perfectly fine. array_push($ipArray,$ipInfo); } } print_r($ipArray); //this is where I'm getting an output of only the last element of `$row`. Thanks! ~Carpetfizz

• Parent Objects

  - by Ali Bahrami

  Support for Parent Objects was added in Solaris 11 Update 1. The following material is adapted from the PSARC arc case, and the Solaris Linker and Libraries Manual. A "plugin" is a shared object, usually loaded via dlopen(), that is used by a program in order to allow the end user to add functionality to the program. Examples of plugins include those used by web browsers (flash, acrobat, etc), as well as mdb and elfedit modules. The object that loads the plugin at runtime is called the "parent object". Unlike most object dependencies, the parent is not identified by name, but by its status as the object doing the load. Historically, building a good plugin is has been more complicated than it should be: A parent and its plugin usually share a 2-way dependency: The plugin provides one or more routines for the parent to call, and the parent supplies support routines for use by the plugin for things like memory allocation and error reporting. It is a best practice to build all objects, including plugins, with the -z defs option, in order to ensure that the object specifies all of its dependencies, and is self contained. However: The parent is usually an executable, which cannot be linked to via the usual library mechanisms provided by the link editor. Even if the parent is a shared object, which could be a normal library dependency to the plugin, it may be desirable to build plugins that can be used by more than one parent, in which case embedding a dependency NEEDED entry for one of the parents is undesirable. The usual way to build a high quality plugin with -z defs uses a special mapfile provided by the parent. This mapfile defines the parent routines, specifying the PARENT attribute (see example below). This works, but is inconvenient, and error prone. The symbol table in the parent already describes what it makes available to plugins — ideally the plugin would obtain that information directly rather than from a separate mapfile. The new -z parent option to ld allows a plugin to link to the parent and access the parent symbol table. This differs from a typical dependency: No NEEDED record is created. The relationship is recorded as a logical connection to the parent, rather than as an explicit object name However, it operates in the same manner as any other dependency in terms of making symbols available to the plugin. When the -z parent option is used, the link-editor records the basename of the parent object in the dynamic section, using the new tag DT_SUNW_PARENT. This is an informational tag, which is not used by the runtime linker to locate the parent, but which is available for diagnostic purposes. The ld(1) manpage documentation for the -z parent option is: -z parent=object Specifies a "parent object", which can be an executable or shared object, against which to link the output object. This option is typically used when creating "plugin" shared objects intended to be loaded by an executable at runtime via the dlopen() function. The symbol table from the parent object is used to satisfy references from the plugin object. The use of the -z parent option makes symbols from the object calling dlopen() available to the plugin. Example For this example, we use a main program, and a plugin. The parent provides a function named parent_callback() for the plugin to call. The plugin provides a function named plugin_func() to the parent: % cat main.c #include <stdio.h> #include <dlfcn.h> #include <link.h> void parent_callback(void) { printf("plugin_func() has called parent_callback()\n"); } int main(int argc, char **argv) { typedef void plugin_func_t(void); void *hdl; plugin_func_t *plugin_func; if (argc != 2) { fprintf(stderr, "usage: main plugin\n"); return (1); } if ((hdl = dlopen(argv[1], RTLD_LAZY)) == NULL) { fprintf(stderr, "unable to load plugin: %s\n", dlerror()); return (1); } plugin_func = (plugin_func_t *) dlsym(hdl, "plugin_func"); if (plugin_func == NULL) { fprintf(stderr, "unable to find plugin_func: %s\n", dlerror()); return (1); } (*plugin_func)(); return (0); } % cat plugin.c #include <stdio.h> extern void parent_callback(void); void plugin_func(void) { printf("parent has called plugin_func() from plugin.so\n"); parent_callback(); } Building this in the traditional manner, without -zdefs: % cc -o main main.c % cc -G -o plugin.so plugin.c % ./main ./plugin.so parent has called plugin_func() from plugin.so plugin_func() has called parent_callback() As noted above, when building any shared object, the -z defs option is recommended, in order to ensure that the object is self contained and specifies all of its dependencies. However, the use of -z defs prevents the plugin object from linking due to the unsatisfied symbol from the parent object: % cc -zdefs -G -o plugin.so plugin.c Undefined first referenced symbol in file parent_callback plugin.o ld: fatal: symbol referencing errors. No output written to plugin.so A mapfile can be used to specify to ld that the parent_callback symbol is supplied by the parent object. % cat plugin.mapfile $mapfile_version 2 SYMBOL_SCOPE { global: parent_callback { FLAGS = PARENT }; }; % cc -zdefs -Mplugin.mapfile -G -o plugin.so plugin.c However, the -z parent option to ld is the most direct solution to this problem, allowing the plugin to actually link against the parent object, and obtain the available symbols from it. An added benefit of using -z parent instead of a mapfile, is that the name of the parent object is recorded in the dynamic section of the plugin, and can be displayed by the file utility: % cc -zdefs -zparent=main -G -o plugin.so plugin.c % elfdump -d plugin.so | grep PARENT [0] SUNW_PARENT 0xcc main % file plugin.so plugin.so: ELF 32-bit LSB dynamic lib 80386 Version 1, parent main, dynamically linked, not stripped % ./main ./plugin.so parent has called plugin_func() from plugin.so plugin_func() has called parent_callback() We can also observe this in elfedit plugins on Solaris systems running Solaris 11 Update 1 or newer: % file /usr/lib/elfedit/dyn.so /usr/lib/elfedit/dyn.so: ELF 32-bit LSB dynamic lib 80386 Version 1, parent elfedit, dynamically linked, not stripped, no debugging information available Related Other Work The GNU ld has an option named --just-symbols that can be used in a similar manner: --just-symbols=filename Read symbol names and their addresses from filename, but do not relocate it or include it in the output. This allows your output file to refer symbolically to absolute locations of memory defined in other programs. You may use this option more than once. -z parent is a higher level operation aimed specifically at simplifying the construction of high quality plugins. Although it employs the same operation, it differs from --just symbols in 2 significant ways: There can only be one parent. The parent is recorded in the created object, and can be displayed by 'file', or other similar tools.

• Slick2d/Nifty-gui input

  - by eerongal

  I'm trying to get input from slick2d into nifty gui. Ive searched online, and I've seen a few examples, but I can't seem to get it working right. i've tried the example on here but I can't seem to get everything working. I'm not entirely sure what I'm doing wrong. I've also looked at examples using the JMonkeyEngine to help point me in the right direction, but still having issues with input. I can get everything else working like i need. Here's the code for my element controller: package gui; import java.util.Properties; import de.lessvoid.nifty.Nifty; import de.lessvoid.nifty.controls.Controller; import de.lessvoid.nifty.elements.Element; import de.lessvoid.nifty.input.NiftyInputEvent; import de.lessvoid.nifty.screen.Screen; import de.lessvoid.xml.xpp3.Attributes; public class BaseElementController implements Controller { private Element element; public void bind(Nifty arg0, Screen arg1, Element arg2, Properties arg3, Attributes arg4) { this.element = element; } public void init(Properties arg0, Attributes arg1) { // TODO Auto-generated method stub } public boolean inputEvent(NiftyInputEvent arg0) { // TODO Auto-generated method stub return false; } public void onFocus(boolean arg0) { // TODO Auto-generated method stub } public void onStartScreen() { // TODO Auto-generated method stub } public void test() { System.out.println("test"); } public void bam() { System.out.println("bam"); } } Here's my XML file: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <nifty> <useStyles filename="nifty-default-styles.xml"/> <useControls filename="nifty-default-controls.xml"/> <screen id="screen2" controller="gui.BaseScreenController"> <layer backgroundColor="#fff0" childLayout="absolute" id="layer4" controller="gui.BaseElementController"> <panel childLayout="center" height="30%" id="panel1" style="nifty-panel-simple" width="50%" x="282" y="334" controller="gui.BaseElementController"> <control id="checkbox1" name="checkbox"/> <control childLayout="center" id="button2" label="button2" name="button" x="381" y="224" visibleToMouse="true" controller="gui.BaseElementController"> <interact onClick="bam()"/> </control> </panel> <text text="${CALL.getPlayerName()}" style="nifty-label" width="100%" height="100%" x="0" y="10" /> </layer> </screen> </nifty> Here's how I'm trying to bind the controller: public void init(GameContainer gc) throws SlickException { Input input = gc.getInput(); inputSystem = new PlainSlickInputSystem(); inputSystem.setInput(input); gui = new Gui(); gui.init(gc, inputSystem, "gui/tset.xml", "screen2"); input.removeListener(this); input.removeListener(inputSystem); input.addListener(inputSystem); } Essentially, all that happens right now is the screen loads up and displays, and it grabs the variable correctly in the label, but none of the input seems to be getting forwarded to Nifty from slick. I assume there's something I'm missing, but I can't seem to figure out what that is. In so far as what I have tried, I attempted to define a custom input listener to pick up events and assign that to my game in order to pick up input, which did not work, so i dropped that implementation, at current i'm trying to take the default inputs and bind then with a PlainSlickInputSystem and assigning that to the input (as shown in the first example link). On code execution, all the code is hit, and i've put several system.out.println's to get ouput of what is happening (the code above has been cleaned for presentation), and i even see the elements getting bound to the controller, yet it doesn't pick up controller events. As far as EXACTLY what's wrong, that I don't know, because I've followed all implementations i can find of this, and none of them seem to do anything it's like the input is just getting thrown out. None of the objects from niftyGui appear to be recognizing any input. Here is the binding from my objects at run time: ******INITIALIZED SCREEN: de.lessvoid.nifty.screen.Screen@4a1ab1c1 ******INITIALIZED ELEMENT: button2 (de.lessvoid.nifty.elements.Element@1e8c1be9) ******INITIALIZED ELEMENT: focusable => true, width => 100px {nifty-button#panel}, backgroundImage => button/button.png {nifty-button#panel}, label => button2, paddingLeft => 7px {nifty-button#panel}, imageMode => sprite-resize:100,23,0,2,96,2,2,2,96,2,19,2,96,2,2 {nifty-button#panel}, paddingRight => 7px {nifty-button#panel}, id => button2, visibleToMouse => true, height => 23px {nifty-button#panel}, style => nifty-button, name => button, inputMapping => de.lessvoid.nifty.input.mapping.MenuInputMapping, childLayout => center, controller => gui.BaseElementController, y => 224, x => 381 ******INITIALIZED SCREEN: de.lessvoid.nifty.screen.Screen@4a1ab1c1 ******INITIALIZED ELEMENT: panel1 (de.lessvoid.nifty.elements.Element@373ec894) ******INITIALIZED ELEMENT: id => panel1, height => 30%, style => nifty-panel-simple, width => 50%, backgroundImage => panel/nifty-panel-simple.png {nifty-panel-simple}, controller => gui.BaseElementController, childLayout => center, padding => 5px {nifty-panel-simple}, imageMode => resize:9,2,9,9,9,2,9,2,9,2,9,9 {nifty-panel-simple}, y => 334, x => 282 ******INITIALIZED SCREEN: de.lessvoid.nifty.screen.Screen@4a1ab1c1 ******INITIALIZED ELEMENT: layer4 (de.lessvoid.nifty.elements.Element@6427d489) ******INITIALIZED ELEMENT: id => layer4, backgroundColor => #fff0, controller => gui.BaseElementController, childLayout => absolute the button2 object is getting bound to my BaseElementController, but i can't seem to get it into the defined "onClick" call.

• "'0.offsetWidth' is null or not an object" - Coda Slider - Javascript Error Question

  I implemented the Coda Slider tutorial successfully that is located here: http://jqueryfordesigners.com/coda-slider-effect/ The slider works great but I am getting a javascript error that I am not sure how to fix.

• Object hierarchy returned by WCF Service is different than expected

  - by robalot

  Good Day Everyone... My understanding may be wrong, but I thought once you applied the correct attributes the DataContractSerializer would render fully-qualified instances back to the caller. The code runs and the objects return. But oddly enough, once I look at the returned objects I noticed the namespacing disappeared and the object-hierarchy being exposed through the (web applications) service reference seems to become "flat" (somehow). Now, I expect this from a web-service…but not through WFC. Of course, my understanding of what WFC can do may be wrong. ...please keep in mind I'm still experimenting with all this. So my questions are… Q: Can I do something within the WFC Service to force the namespacing to render through the (service reference) data client proxy? Q: Or perhaps, am I (merely) consuming the service incorrectly? Q: Is this even possible? The service code looks like… [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] public class DataService : IFishData { public C1FE GetC1FE(Int32 key) { //… more stuff here … } public Project GetProject(Int32 key) { //… more stuff here … } } [ServiceContract] [ServiceKnownType(typeof(wcfFISH.StateManagement.C1FE.New))] [ServiceKnownType(typeof(wcfFISH.StateManagement.Project.New))] public interface IFishData { [OperationContract] C1FE GetC1FE(Int32 key); [OperationContract] Project GetProject(Int32 key); } [DataContract] [KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class Project { [DataMember] public wcfFISH.StateManagement.ObjectState ObjectState { get; set; } //… more stuff here … } [DataContract] KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class C1FE { [DataMember] public wcfFISH.StateManagement.ObjectState ObjectState { get; set; } //… more stuff here … } [DataContract(Namespace = "wcfFISH.StateManagement")] [KnownType(typeof(wcfFISH.StateManagement.C1FE.New))] [KnownType(typeof(wcfFISH.StateManagement.Project.New))] public abstract class ObjectState { //… more stuff here … } [DataContract(Namespace = "wcfFISH.StateManagement.C1FE", Name="New")] [KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class New : ObjectState { //… more stuff here … } [DataContract(Namespace = "wcfFISH.StateManagement.Project", Name = "New")] [KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class New : ObjectState { //… more stuff here … } The web application code looks like… public partial class Fish_Invite : BaseForm { protected void btnTest_Click(object sender, EventArgs e) { Project project = new Project(); project.Get(base.ProjectKey, base.AsOf); mappers.Project mapProject = new mappers.Project(); srFish.Project fishProject = new srFish.Project(); srFish.FishDataClient fishService = new srFish.FishDataClient(); mapProject.MapTo(project, fishProject); fishProject = fishService.AddProject(fishProject, IUser.UserName); project = null; } } In case I’m not being clear… The issue arises as there is a difference in (the name spacing) that I expect to see (returned) is different from what is actually returned. fishProject.ObjectState should look like... srFish.StateManagement.Project.New fishC1FE.ObjectState should look like... srFish.StateManagement.C1FE.New fishProject.ObjectState looks like... srFish.New1 fishC1FE.ObjectState looks like... srFish.New …“Help me Obi-Wan Kenobi, you’re my only hope!”

• Java Refuses to Start - Could not reserve enough space for object heap

  - by Randyaa

  Background We have a pool of aproximately 20 linux blades. Some are running Suse, some are running Redhat. ALL share NAS space which contains the following 3 folders: /NAS/app/java - a symlink that points to an installation of a Java JDK. Currently version 1.5.0_10 /NAS/app/lib - a symlink that points to a version of our application. /NAS/data - directory where our output is written All our machines have 2 processors (hyperthreaded) with 4gb of physical memory and 4gb of swap space. We limit the number of 'jobs' each machine can process at a given time to 6 (this number likely needs to change, but that does not enter into the current problem so please ignore it for the time being). Some of our jobs set a Max Heap size of 512mb, some others reserve a Max Heap size of 2048mb. Again, we realize we could go over our available memory if 6 jobs started on the same machine with the heap size set to 2048, but to our knowledge this has not yet occurred. The Problem Once and a while a Job will fail immediately with the following message: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. We used to chalk this up to too many jobs running at the same time on the same machine. The problem happened infrequently enough (MAYBE once a month) that we'd just restart it and everything would be fine. The problem has recently gotten much worse. All of our jobs which request a max heap size of 2048m fail immediately almost every time and need to get restarted several times before completing. We've gone out to individual machines and tried executing them manually with the same result. Debugging It turns out that the problem only exists for our SuSE boxes. The reason it has been happening more frequently is becuase we've been adding more machines, and the new ones are SuSE. 'cat /proc/version' on the SuSE boxes give us: Linux version 2.6.5-7.244-bigsmp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Mon Dec 12 18:32:25 UTC 2005 'cat /proc/version' on the RedHat boxes give us: Linux version 2.4.21-32.0.1.ELsmp ([email protected]) (gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-52)) #1 SMP Tue May 17 17:52:23 EDT 2005 'uname -a' gives us the following on BOTH types of machines: UTC 2005 i686 i686 i386 GNU/Linux No jobs are running on the machine, and no other processes are utilizing much memory. All of the processes currently running might be using 100mb total. 'top' currently shows the following: Mem: 4146528k total, 3536360k used, 610168k free, 132136k buffers Swap: 4194288k total, 0k used, 4194288k free, 3283908k cached 'vmstat' currently shows the following: procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 610292 132136 3283908 0 0 0 2 26 15 0 0 100 0 If we kick off a job with the following command line (Max Heap of 1850mb) it starts fine: java/bin/java -Xmx1850M -cp helloworld.jar HelloWorld Hello World If we bump up the max heap size to 1875mb it fails: java/bin/java -Xmx1875M -cp helloworld.jar HelloWorld Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. It's quite clear that the memory currently being used is for Buffering/Caching and that's why so little is being displayed as 'free'. What isn't clear is why there is a magical 1850mb line where anything higher means Java can't start. Any explanations would be greatly appreciated.

• How to remove a model object from an EMF model and its GEF Editor via Adapter

  - by s.d

  This question is principally a follow-up to my question about EMF listening mechanisms. So, I have a third-party EMF model (uneditable) which is based on a generic graph model. The structure is as follows: Project | ItemGraph | Item | Document | DocumentGraph / | \ Tokens Nodes Relations(Edges) I have a GEF editor which works on the DocumentGraph (i.e., not the root object, perhaps this is a problem?): getGraphicalViewer().setContents(documentGraph). THe editor has the following edit part structure: DocumentGraphEP / \ Primary Connection LayerEP LayerEP / \ | TokenEP NodeEP RelationEP PrimaryLayerEP and ConnectionLayerEP both have simple Strings as model, which are not represented in the EMF (domain) model. They are simply used to add a primary (i.e., node) layer, and a connection layer (with ShortestPathConnectionRouter) to the editor. Problem: I am trying to get myself into the workings of EMF adapters, and have tried to make use of the available tutorials, mainly the EMF-GEF Eclipse tutorial, vainolo's blog, and vogella's tutorial. I thought I'd start with an easy thing, so tried to remove a node from the graph and see if I get it to work. Which I didn't, and I don't see where the problem is. I can select a node, and have the generic delete Action in my toolbar, but when I click it, nothing happens. Here is the respective source code for the different responsible parts. Please be so kind to point me to any errors (of thinking, coding errors, whathaveyou) you can find. NodeEditPart public class NodeEditPart extends AbstractGraphicalEditPart implements Adapter { protected IFigure createFigure() { return new NodeFigure(); } protected void createEditPolicies() { .... installEditPolicy(EditPolicy.COMPONENT_ROLE, new NodeComponentEditPolicy()); } protected void refreshVisuals() { NodeFigure figure = (NodeFigure) getFigure(); SNode model = (SNode) getModel(); PrimaryLayerEditPart parent = (PrimaryLayerEditPart) getParent(); // Set text figure.getLabel().setText(model.getSName()); .... } public void activate() { if (isActive()) return; // start listening for changes in the model ((Notifier)getModel()).eAdapters().add(this); super.activate(); } public void deactivate() { if (!isActive()) return; // stop listening for changes in the model ((Notifier)getModel()).eAdapters().remove(this); super.deactivate(); } private Notifier getSDocumentGraph() { return ((SNode)getModel()).getSDocumentGraph(); } @Override public void notifyChanged(Notification notification) { int type = notification.getEventType(); switch( type ) { case Notification.ADD: case Notification.ADD_MANY: case Notification.REMOVE: case Notification.REMOVE_MANY: refreshChildren(); break; case Notification.SET: refreshVisuals(); break; } } @Override public Notifier getTarget() { return target; } @Override public void setTarget(Notifier newTarget) { this.target = newTarget; } @Override public boolean isAdapterForType(Object type) { return type.equals(getModel().getClass()); } } NodeComponentEditPolicy public class NodeComponentEditPolicy extends ComponentEditPolicy { public NodeComponentEditPolicy() { super(); } protected Command createDeleteCommand(GroupRequest deleteRequest) { DeleteNodeCommand cmd = new DeleteNodeCommand(); cmd.setSNode((SNode) getHost().getModel()); return cmd; } } DeleteNodeCommand public class DeleteNodeCommand extends Command { private SNode node; private SDocumentGraph graph; @Override public void execute() { node.setSDocumentGraph(null); } @Override public void undo() { node.setSDocumentGraph(graph); } public void setSNode(SNode node) { this.node = node; this.graph = node.getSDocumentGraph(); } } All seems to work fine: When a node is selected in the editor, the delete symbol is activated in the toolbar, but when it is clicked, nothing happens in the editor. I'd be very thankful for any pointers :).

• Symfony2: validate an object that is not an entity

  - by Marronsuisse

  I am using CraueFormFlowBundle to have a multiple page form, and am trying to do some validation on some of the fields but can't figure out how to do this. The object that needs to be validated isn't an Entity, which is causing me trouble. I tried adding a collectionConstraint in the getDefaultOption function of my form type class, but this doesn't work as I get the "Expected argument of type array or Traversable and ArrayAccess" error. I tried with annotations in my object class, but they don't seem to be taken into account. Are annotations taken into account if the class isn't an entity? (i set enable_annotations to true) Anyway, what is the proper way to do this? Basically, I just want to validate that "age" is an integer... class PoemDataCollectorFormType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { switch ($options['flowStep']) { case 6: $builder->add('msgCategory', 'hidden', array( )); $builder->add('msgFIB','text', array( 'required' => false, )); $builder->add('age', 'integer', array( 'required' => false, )); break; } } public function getDefaultOptions(array $options) { $options = parent::getDefaultOptions($options); $options['flowStep'] = 1; $options['data_class'] = 'YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector'; $options['intention'] = 'my_secret_key'; return $options; } } EDIT: add code, handle validation with annotations As Cyprian, I was pretty sure that using annotations should work, however it doesn't... Here is how I try: In my Controller: public function collectPoemDataAction() { $collector = $this->get('yop.poem.datacollector'); $flow = $this->get('yop.form.flow.poemDataCollector'); $flow->bind($collector); $form = $flow->createForm($collector); if ($flow->isValid($form)) { .... } } In my PoemDataCollector class, which is my data class (service yop.poem.datacollector): class PoemDataCollector { /** * @Assert\Type(type="integer", message="Age should be a number") */ private $age; } EDIT2: Here is the services implementation: The data class (PoemDataCollector) seems to be linked to the flow class and not to the form.. Is that why there is no validation? <service id="yop.poem.datacollector" class="YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector"> </service> <service id="yop.form.poemDataCollector" class="YOP\YourOwnPoetBundle\Form\Type\PoemDataCollectorFormType"> <tag name="form.type" alias="poemDataCollector" /> </service> <service id="yop.form.flow.poemDataCollector" class="YOP\YourOwnPoetBundle\Form\PoemDataCollectorFlow" parent="craue.form.flow" scope="request"> <call method="setFormType"> <argument type="service" id="yop.form.poemDataCollector" /> </call> </service> How can I do the validation while respecting the craueFormFlowBundle guidelines? The guidelines state: Validation groups To validate the form data class a step-based validation group is passed to the form type. By default, if getName() of the form type returns registerUser, such a group is named flow_registerUser_step1 for the first step. Where should I state my constraint to use those validation groups..? I tried: YOP\YourOwnPoetBundle\PoemBuilder\Form\Type\PoemDataCollectorFormType: properties: name: - MinLength: { limit: 5, message: "Your name must have at least {{ limit }} characters.", groups: [flow_poemDataCollector_step1] } sex: - Type: type: integer message: Please input a number groups: [flow_poemDataCollector_step6] But it is not taken into acount.

• Jaxb unmarshalls fixml object but all fields are null

  - by DUFF

  I have a small XML document in the FIXML format. I'm unmarshalling them using jaxb. The problem The process complete without errors but the objects which are created are completely null. Every field is empty. The fields which are lists (like the Qty) have the right number of object in them. But the fields of those objects are also null. Setup I've downloaded the FIXML schema from here and I've created the classes with xjc and the maven plugin. They are all in the package org.fixprotocol.fixml_5_0_sp2. I've got the sample xml in a file FIXML.XML <?xml version="1.0" encoding="ISO-8859-1"?> <FIXML> <Batch> <PosRpt> <Pty ID="GS" R="22"/> <Pty ID="01" R="5"/> <Pty ID="6U8" R="28"> <Sub ID="2" Typ="21"/> </Pty> <Pty ID="GS" R="22"/> <Pty ID="6U2" R="2"/> <Instrmt ID="GHPKRW" SecTyp="FWD" MMY="20121018" MatDt="2012-10-18" Mult="1" Exch="GS" PxQteCcy="KJS" FnlSettlCcy="GBP" Fctr="0.192233298" SettlMeth="G" ValMeth="FWDC2" UOM="Ccy" UOMCCy="USD"> <Evnt EventTyp="121" Dt="2013-10-17"/> <Evnt EventTyp="13" Dt="2013-10-17"/> </Instrmt> <Qty Long="0.000" Short="22000000.000" Typ="PNTN"/> <Qty Long="0.000" Short="22000000.000" Typ="FIN"/> <Qty Typ="DLV" Long="0.00" Short="0.00" Net="0.0"/> <Amt Typ="FMTM" Amt="32.332" Ccy="USD"/> <Amt Typ="CASH" Amt="1" Rsn="3" Ccy="USD"/> <Amt Typ="IMTM" Amt="329.19" Ccy="USD"/> <Amt Typ="DLV" Amt="0.00" Ccy="USD"/> <Amt Typ="BANK" Amt="432.23" Ccy="USD"/> </PosRpt> Then I'm calling the unmarshaller with custom event handler which just throws an exception on a parse error. The parsing complete so I know there are no errors being generated. I'm also handling the namespace as suggested here // sort out the file String xmlFile = "C:\\FIXML.XML.xml"; System.out.println("Loading XML File..." + xmlFile); InputStream input = new FileInputStream(xmlFile); InputSource is = new InputSource(input); // create jaxb context JAXBContext jc = JAXBContext.newInstance("org.fixprotocol.fixml_5_0_sp2"); Unmarshaller unmarshaller = jc.createUnmarshaller(); // add event handler so jacB will fail on an error CustomEventHandler validationEventHandler = new CustomEventHandler(); unmarshaller.setEventHandler(validationEventHandler); // set the namespace NamespaceFilter inFilter = new NamespaceFilter("http://www.fixprotocol.org/FIXML-5-0-SP2", true); inFilter.setParent(SAXParserFactory.newInstance().newSAXParser().getXMLReader()); SAXSource source = new SAXSource(inFilter, is); // GO! JAXBElement<FIXML> fixml = unmarshaller.unmarshal(source, FIXML.class); The fixml object is created. In the above sample the Amt array will have five element which matches the number of amts in the file. But all the fields like ccy are null. I've put breakpoints in the classes created by xjc and none of the setters are ever called. So it appears that jaxb is unmarshalling and creating all the correct objects, but it's never calling the setters?? I'm completely stumped on this. I've seen a few posts that suggrest making sure the package.info file that was generated by xjc is in the packags and I've made sure that it's there. There are no working in the IDE about the generated code. Any help much appreciated.

• Android inserting into SQLite JSON object

  - by Nizmon

  I'm trying to insert the below json response from a server into my sqlite DB and then read from the DB. The problem I am getting is that when I run my code it compiles fine and runs with no errors. But when trying to read from the DB I just get back what seems like an empty string so I know that the table is being created. I have the correct permissions within the manifest. I have also reference all my classes within there. {"locations": [{"locations":"Newcastle","location_id":"1"},{"locations":"London","location_id":"2"},{"locations":"Sunderland","location_id":"3"}]} Below where I use: Log.v("one", one); Log.v("two", two); below It only prints out the first set within the JSON object so Newcastle and 1. I don't get any errors at all which is stumping me. When I call the method getName within the Location class I just seem to get a blank string back! // This class creates the table as well as inserts and returns data from the sqlite DB public class Location { private DatabaseHelper mDbHelper; private SQLiteDatabase mDb; private final Context mCtx; private static final String vd_location = ("CREATE TABLE " + TABLE_VD_LOCATION + " (" + LOCATION + " TEXT," + LOCATION_ID + " TEXT " +");"); private static class DatabaseHelper extends SQLiteOpenHelper { DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL(vd_location); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { } } public Location(Context ctx) { this.mCtx = ctx; } public Location open() throws SQLException { this.mDbHelper = new DatabaseHelper(this.mCtx); this.mDb = this.mDbHelper.getWritableDatabase(); return this; } public void close() { this.mDbHelper.close(); } public void addOffer (JSONObject json){ try{ JSONArray earthquakes = json.getJSONArray("offers"); for(int i=0;i<earthquakes.length();i++){ open(); JSONObject e = earthquakes.getJSONObject(i); String one = e.getString("locations"); String two = e.getString("location_id"); Log.v("one", one); Log.v("two", two); mDb.execSQL("INSERT INTO " + TABLE_VD_LOCATION + " ( locations, location_id ) " + "VALUES (?, ?)", new Object [] { e.getString("locations"), e.getString("location_id")}); close(); } }catch(Exception e){ }finally{ close(); } } public String getName(long l) throws SQLException{ String[] columns = new String[]{ LOCATION, LOCATION_ID}; Cursor c = mDb.query(TABLE_VD_LOCATION, columns, null, null, null, null, null); String result = ""; int iRow = c.getColumnIndex(LOCATION); int iName = c.getColumnIndex(LOCATION_ID); for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()){ result = result + c.getString(iRow) + " " + c.getString(iName) + " " + "\n"; } return result; } } // This code reads from the DB, this is just some very hacked together code so excuse it, it also works when used on other tables public void getData(){ boolean didItWork = true; try { Location loc = new Location(this); loc.open(); String data = loc.getName(0); loc.close(); Dialog t = new Dialog(this); t.setTitle("get" + data); t.show(); } catch (Exception e) { didItWork = false; String error = e.toString(); Dialog d = new Dialog(this); d.setTitle("Dang it!"); TextView tv = new TextView(this); tv.setText(error); d.setContentView(tv); d.show(); } finally { if (didItWork) { Dialog d = new Dialog(this); d.setTitle("Heck Yea!"); TextView tv = new TextView(this); tv.setText("Success"); d.setContentView(tv); d.show(); //entry.close(); } } }
