  • Convert Javascript Regular Expression to PHP (PCRE) Expression

    - by Matt
    Hi all, I am up to my neck in regular expressions, and I have this regular expression that works in javascript (and flash) that I just can't get working in PHP Here it is: var number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; var oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]' + '|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; var str = '(?:\"' + oneChar + '*\")'; var varName = '\\$(?:' + oneChar + '[^ ,]*)'; var func = '(?:{[ ]*' + oneChar + '[^ ]*)'; // Will match a value in a well-formed JSON file. // If the input is not well-formed, may match strangely, but not in an unsafe // way. // Since this only matches value tokens, it does not match whitespace, colons, // or commas. var jsonToken = new RegExp( '(?:false|true|null' +'|[\\}]' + '|' + varName + '|' + func + '|' + number + '|' + str + ')', 'g'); If you want it fully assembled here it is: /(?:false|true|null|[\}]|\$(?:(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ,]*)|(?:{[ ]*(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ]*)|(?:-?\b(?:0|[1-9][0-9]*)(?:\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\b)|(?:"(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))*"))/g Interestingly enough, its very similar to JSON. I need this regular expression to work in PHP... Here's what I have in PHP: $number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; $oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; $string = '(?:\"'.$oneChar.'*\")'; $varName = '\\$(?:'.$oneChar.'[^ ,]*)'; $func = '(?:{[ ]*'.$oneChar.'[^ ]*)'; $jsonToken = '(?:false|true|null' .'|[\\}]' .'|'.$varName .'|'.$func .'|'.$number .'|'.$string .')'; echo $jsonToken; preg_match_all($jsonToken, $content, $out); return $out; Here's what happens if I try using preg_match_all(): Warning: preg_match_all() [function.preg-match-all]: Compilation failed: nothing to repeat at offset 0 in /Users/Matt/Sites/Templating/json/Jeeves.php on line 88 Any help would be much appreciated! Thanks, Matt

  • Weird RecordStore behavior when RecordStoreFullException occurs

    - by Michael P
    Hello everyone! I'm developing a small J2ME application that displays bus stops timetables - they are stored as records in MIDP RecordStores. Sometimes records can not fit a single RecordStore, especially on record update - using setRecord method - a RecordStoreFullException occurs. I catch the exception, and try to write the record to a new RecordStore along with deleting the previous one in the old RecordStore. Everything works fine except of deleting record from RecordStore where the RecordStoreFullException occurs. If I make an attempt to delete record that could not be updated, another Exception of type InvalidRecordIDException is thrown. This is weird and undocumented in MIDP javadoc. I have tested it on Sun WTK 2.5.2, MicroEdition SDK 3.0 and Nokia Series 40 SDK. Furthermore I created a code that reproduces this strange behaviour: RecordStore rms = null; int id = 0; try { rms = RecordStore.openRecordStore("Test", true); byte[] raw = new byte[192*10024]; //Big enough to cause RecordStoreFullException id = rms.addRecord(raw, 0, 160); rms.setRecord(id, raw, 0, raw.length); } catch (Exception e) { try { int count = rms.getNumRecords(); RecordEnumeration en = rms.enumerateRecords(null, null, true); count = en.numRecords(); while(en.hasNextElement()){ System.out.println("NextID: "+en.nextRecordId()); } rms.deleteRecord(id); //this won't work! rms.setRecord(id, new byte[5], 0, 5); //this won't work too! } catch (Exception ex) { ex.printStackTrace(); } } I added extra enumeration code to produce other weird behavior - when RecordStoreFullException occurs, count variable will be set to 1 (if RMS was empty) by both methods - getNumRecords and numRecords. System.out.println will produce NextID: 0! It is not acceptable because record ID can not be 0! Could someone explain this strange behavior? Sorry for my bad English.

  • EJB3 JNDI Lookup Failure in JEE application client

    - by Hank
    I'm trying to access an EJB3 from a JEE client-application, but keep getting nothing but lookup failures. My JEE Application 'CoreServer' is exposing a number of beans with remote interfaces. I have no problem accessing them from a Web Application deployed on the same Glassfish v3.0.1. Now I'm trying to access it from a client-application: public class Main { public static void main(String[] args) { CampaignControllerRemote bean = null; try { InitialContext ctx = new InitialContext(); bean = (CampaignControllerRemote) ctx.lookup("java:global/CoreServer/CampaignController"); } catch (Exception e) { System.out.println(e.getMessage()); } if (bean != null) { Campaign campaign = bean.get(361); if (campaign != null) { System.out.println("Got "+ campaign); } } } } When I run deploy it to Glassfish and run it from the appclient, I get this error: Lookup failed for 'java:global/CoreServer/CampaignController' in SerialContext targetHost=localhost,targetPort=3700,orb'sInitialHost=localhost,orb'sInitialPort=3700 However, that's exactly the same JNDI-name I use when I lookup the bean from the WebApplication (via SessionContext, not InitialContext - does that matter?). Also, when I deploy 'CoreServer', Glassfish reports: Portable JNDI names for EJB CampaignController : [java:global/CoreServer/CampaignController!mvs.api.CampaignControllerRemote, java:global/CoreServer/CampaignController] Glassfish-specific (Non-portable) JNDI names for EJB CampaignController : [mvs.api.CampaignControllerRemote, mvs.api.CampaignControllerRemote#mvs.api.CampaignControllerRemote] I tried all four names, none worked. Is the appclient unable to access beans with (only) Remote interfaces?

  • Unresolved Host Exception Android

    - by Rob Stevenson-Leggett
    I'm trying to call a RESTful web service from an Android application using the following method: HttpHost target = new HttpHost("http://" + ServiceWrapper.SERVER_HOST,ServiceWrapper.SERVER_PORT); HttpGet get = new HttpGet("/list"); String result=null; HttpEntity entity = null; HttpClient client = new DefaultHttpClient(); try { HttpResponse response=client.execute(target, get); entity = response.getEntity(); result = EntityUtils.toString(entity); } catch (Exception e) { e.printStackTrace(); } finally { if (entity!=null) try { entity.consumeContent(); } catch (IOException e) {} } return result; I can browse to address and see the xml results using the Android Emulator browser and from my machine. I have given my app the INTERNET permission. I'm developing with eclipse. I've seen it mentioned that I might need to configure a proxy but since the web service i'm calling is on port 80 this shouldn't matter should it? I can call the method with the browser. Any ideas?

  • Django one form for two models

    - by martinthenext
    Hello! I have a ForeignKey relationship between TextPage and Paragraph and my goal is to make front-end TextPage creating/editing form as if it was in ModelAdmin with 'inlines': several field for the TextPage and then a couple of Paragraph instances stacked inline. The problem is that i have no idea about how to validate and save that: @login_required def textpage_add(request): profile = request.user.profile_set.all()[0] if not (profile.is_admin() or profile.is_editor()): raise Http404 PageFormSet = inlineformset_factory(TextPage, Paragraph, extra=5) if request.POST: try: textpageform = TextPageForm(request.POST) # formset = PageFormSet(request.POST) except forms.ValidationError as error: textpageform = TextPageForm() formset = PageFormSet() return render_to_response('textpages/manage.html', { 'formset' : formset, 'textpageform' : textpageform, 'error' : str(error), }, context_instance=RequestContext(request)) # Saving data if textpageform.is_valid() and formset.is_valid(): textpageform.save() formset.save() return HttpResponseRedirect(reverse(consults)) else: textpageform = TextPageForm() formset = PageFormSet() return render_to_response('textpages/manage.html', { 'formset' : formset, 'textpageform' : textpageform, }, context_instance=RequestContext(request)) I know I't a kind of code-monkey style to post code that you don't even expect to work but I wanted to show what I'm trying to accomplish. Here is the relevant part of models.py: class TextPage(models.Model): title = models.CharField(max_length=100) page_sub_category = models.ForeignKey(PageSubCategory, blank=True, null=True) def __unicode__(self): return self.title class Paragraph(models.Model): article = models.ForeignKey(TextPage) title = models.CharField(max_length=100, blank=True, null=True) text = models.TextField(blank=True, null=True) def __unicode__(self): return self.title Any help would be appreciated.

  • codeigniter & cjax framework, fatal error class 'CI_Controller' not found

    - by Martin
    I'm having this weird error with Codeigniter 2.1.3 and latest cjax for codeigniter. Weird thing is, when I download the latest codeigniter, and latest cjax framework for codeitniger and copy to my friends server, and call: domain.com/ajax.php?test/test2 to show the test ajax examples ... it works like a breeze, but when I do this on my server, I get server error (even tho, we both have same php version and such). Server then throws in error log file this error: PHP Fatal error: Class 'CI_Controller' not found in /hosting/www/domain.com/www/application/response/test.php on line 3 Now, I've read thru stackoverflow with people having this problem and solving by changing the construct and calling CI_Controller instead of Controller. But I already do that ... - I mean it's in the basic example that is suppose to work without touching the code, and it does, just not on my domain for some crappy reason. Ajax.php from cjax framework for codeingter should load controller from folder response, named test and call function test2, which looks like this (the actual file named test.php): class Test extends CI_Controller { function __construct() { parent::__construct(); } /** * * ajax.php?test/test/a/b/c * * @param unknown_type $a * @param unknown_type $b * @param unknown_type $c */ function test($a = null,$b = null, $c = null) { $this->load->view('test', array('data' => $a .' '.$b.' '.$c)); } /** * ajax.php?test/test2 * * Here we are testing out the javascript library. * * Note: the library it is not meant to be included in ajax controllers - but in front-controllers, * it is being used here for the sake of simplicity in testing. */ function test2() { $ajax = ajax(); $ajax->update('response','Cjax Works'); $ajax->append('#response','<br /><br />version: '.$ajax->version); $ajax->success('Cjax was successfully installed.', 5); //see application/views/test2.php $this->load->view('test2'); } I was hoping someone could bring some light into this problem - or maybe someone has already experienced it? Thanks for your time! Mart

  • LINQ-to-SQL: Could not find key member 'x' of key 'x' on type 'y'

    - by Austin Hyde
    I am trying to connect my application to a SQLite database with LINQ-to-SQL, and so far everything has worked fine. The only hitch was that the SQLite provider I am using does not support code generation (unless I was doing something wrong), so I manually coded the 4 tables in the DB. The solution builds properly, but will not run, giving me the error message Could not find key member 'ItemType_Id' of key 'ItemType_Id' on type 'Item'. The key may be wrong or the field or property on 'Item' has changed names. I have checked and double checked spellings and field names on the database and in the attribute mappings, but could not find any problems. The SQL for the table looks like this: CREATE TABLE [Items] ( [Id] integer PRIMARY KEY AUTOINCREMENT NOT NULL, [Name] text NOT NULL, [ItemType_Id] integer NOT NULL ); And my mapping code: [Table(Name="Items")] class Item { // [snip] [Column(Name = "Id", IsPrimaryKey=true, IsDbGenerated=true)] public int Id { get; set; } // [snip] [Column(Name="ItemType_Id")] public int ItemTypeId { get; set; } [Association(Storage = "_itemType", ThisKey = "ItemType_Id")] public ItemType ItemType { get { return _itemType.Entity; } set { _itemType.Entity = value; } } private EntityRef<ItemType> _itemType; // [snip] } This is really my first excursion into LINQ-to-SQL, and am learning as I go, but I cannot seem to get past this seeming simple problem. Why cannot LINQ see my association?

  • WCF sending the same exception even if the service endpoint address is valid

    - by ALexr111
    Hi, I'm running into a really strange problem with WCF. I need to implement some recovery behavior for WCF service if not reachable endpoint IP address received or service can not bind. The flow is simple if the application fail on exception on service creation it terminate it and request from user another IP address and perform another attempt to create the service. (The code snippet below). If the address is not valid I get "A TCP error (10049: The requested address is not valid in its context) occurred while listening on IP Endpoint=.121.10.11.11" exception, but for any reason if I try the second attempt with valid address I've got the same exception with wrong IP address from previous attempt. Here is a code: ServiceHost service = null; try { Uri[] uris = { new Uri(Constants.PROTOCOL + "://" + address + ":" + port) }; service = new ServiceHost(typeof(IRemoteService), uris); NetTcpBinding tcpBinding = WcfTcpRemoteServicesManager.LessLimitedNewNetTcpBinding(int.MaxValue, int.MaxValue, int.MaxValue); ServiceEndpoint ep = service.AddServiceEndpoint(implementedContract.FullName, tcpBinding, serviceName); var throttle = service.Description.Behaviors.Find<ServiceThrottlingBehavior>(); if (throttle == null) { throttle = new ServiceThrottlingBehavior { MaxConcurrentCalls = Constants.MAX_CONCURRENT_CALLS, MaxConcurrentSessions = Constants.MAX_CONCURRENT_SESSIONS, MaxConcurrentInstances = Constants.MAX_CONCURRENT_INSTANCES }; service.Description.Behaviors.Add(throttle); } service.Open(); } catch (Exception e) { _debugLog.WriteLineMessage( "Failed to open or create service exception. Exception message:" + e.Message); if (service!=null) { try { service.Close(); } catch (Exception) { service.Abort(); service.Close(); throw e; } } } Thanks

  • WCF: Serializing and Deserializing generic collections

    - by Fabiano
    I have a class Team that holds a generic list: [DataContract(Name = "TeamDTO", IsReference = true)] public class Team { [DataMember] private IList<Person> members = new List<Person>(); public Team() { Init(); } private void Init() { members = new List<Person>(); } [System.Runtime.Serialization.OnDeserializing] protected void OnDeserializing(StreamingContext ctx) { Log("OnDeserializing of Team called"); Init(); if (members != null) Log(members.ToString()); } [System.Runtime.Serialization.OnSerializing] private void OnSerializing(StreamingContext ctx) { Log("OnSerializing of Team called"); if (members != null) Log(members.ToString()); } [System.Runtime.Serialization.OnDeserialized] protected void OnDeserialized(StreamingContext ctx) { Log("OnDeserialized of Team called"); if (members != null) Log(members.ToString()); } [System.Runtime.Serialization.OnSerialized] private void OnSerialized(StreamingContext ctx) { Log("OnSerialized of Team called"); Log(members.ToString()); } When I use this class in a WCF service, I get following log output OnSerializing of Team called System.Collections.Generic.List 1[Person] OnSerialized of Team called System.Collections.Generic.List 1[Person] OnDeserializing of Team called System.Collections.Generic.List 1[ENetLogic.ENetPerson.Model.FirstPartyPerson] OnDeserialized of Team called ENetLogic.ENetPerson.Model.Person[] After the deserialization members is an Array and no longer a generic list although the field type is IList< (?!) When I try to send this object back over the WCF service I get the log output OnSerializing of Team called ENetLogic.ENetPerson.Model.FirstPartyPerson[] After this my unit test crashes with a System.ExecutionEngineException, which means the WCF service is not able to serialize the array. (maybe because it expected a IList<) So, my question is: Does anybody know why the type of my IList< is an array after deserializing and why I can't serialize my Team object any longer after that? Thanks

  • .NET remoting exception: Permission denied: cannot call non-public or static methods remotely.

    - by Vilx-
    I'm writing a program which will allow to load a specific managed .DLL file and play with it. Since I want the ability to unload the .DLL file, I'm creating two AppDomains - one for the app itself, the other for the currently loaded .DLL. Since most of the objects in the loaded .DLL do not serialize well, I'm creating a MarshalByRefObject wrapper class which will keep the object itself in its own AppDomain, and expose some reflection functions to the main application AppDomain. However when I try to invoke a method on the remote object I get stuck with an exception: Permission denied: cannot call non-public or static methods remotely. This is very strange, because I'm not using any non-public or static methods at all. In essence, what I have is: class RemoteObjectWrapper: MarshalByRefObject { private Type SourceType; private object Source; public RemoteObjectWrapper(object source) { if (source == null) throw new ArgumentNullException("source"); this.Source = source; this.SourceType = source.GetType(); } public T WrapValue<T>(object value) { if ( value == null ) return default(T); var TType = typeof(T); if (TType == typeof(RemoteObjectWrapper)) value = new RemoteObjectWrapper(value); return (T)value; } public T InvokeMethod<T>(string methodName, params object[] args) { return WrapValue<T>(SourceType.InvokeMember(methodName, System.Reflection.BindingFlags.FlattenHierarchy | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.InvokeMethod | System.Reflection.BindingFlags.Public, null, this.Source, args)); } } And I get the exception when I try to do: var c = SomeInstanceOfRemoteObjectWrapper.InvokeMethod<RemoteObjectWrapper>("somePublicMethod", "some string parameter"); What's going on here? As far as I can understand, the InvokeMethod method doesn't even get executed, the exception is thrown when I try to run it. Added: To clarify - SomeInstanceOfRemoteObjectWrapper is constructed in the .DLL's AppDomain and then returned to my main AppDomain, The InvokeMethod<T>() is called from my main AppDomain (and I expect it to execute in the .DLL's AppDomain).

  • How to apply stereotypes on UML Relationships' MemberEnds?

    - by Cristi Potlog
    I'm running this code on a UML Class Diagram, and it works just fine, but when trying to apply stereotypes from PropertiesEditor in Visual Studio for relationship ends (FirstRole and SecondRole), the stereotypes combo doesn't load even if in code there seems to be applicable stereotypes valid for association properties. What should I put in metaclasses tag in the UML profile except for IProperty? <metaclassMoniker name="/MyUmlProfile/Microsoft.VisualStudio.Uml.Classes.IProperty"/> This is the code: using Microsoft.VisualStudio.Uml.Classes; foreach( IShape shape in currentDiagram.GetSelectedShapes<IElement>() ) { IElement element = shape.GetElement(); foreach( IStereotype stereotype in element.ApplicableStereotypes ) { if( element is Microsoft.VisualStudio.Uml.Classes.IClass ) { IClass classItem = (IClass)element; if( classItem.SuperClasses.Count() > 0 ) { if( stereotype.Name == "SubclassAttribute" ) { element.ApplyStereotype( stereotype ); } } else if( stereotype.Name == "ClassAttribute" ) { element.ApplyStereotype( stereotype ); } } else if( element is Microsoft.VisualStudio.Uml.Classes.IProperty ) { IProperty property = (IProperty)element; if( property.Association != null ) { if( stereotype.Name == "Set" && property.UpperValue != null && property.UpperValue.ToString() == "*" ) { element.ApplyStereotype( stereotype ); } else if( stereotype.Name == "ManyToOne" && ( property.UpperValue == null || property.UpperValue.ToString() == "1" ) ) { element.ApplyStereotype( stereotype ); } } else if( stereotype.Name == "Property" ) { element.ApplyStereotype( stereotype ); } } } }

  • Outlook Interop Send Message from Account

    - by Reiste
    Okay, the specs have changed on this one somewhat. Maybe someone can help me with this new problem. Manually, what the user is doing is opening an new message in Outlook (2007 now) which has the "From..." field exposed. They open this up, select a certain account from the Global Address List, and send the message on behalf of that account. Is this possible to do? I can get the AddressEntry from the Global address list like so: AddressList list = null; foreach (AddressList addressList in _outlookApp.Session.AddressLists) { if (addressList.Name.ToLower().Equals("global address list")) { list = addressList; break; } } if (list != null) { AddressEntry entry = null; foreach (AddressEntry addressEntry in list.AddressEntries) { if (addressEntry.Name.ToLower().Equals("outgoing mail account")) { entry = addressEntry; break; } } } But I'm not sure I can make an Account type from the Address Entry. It seems to happen manually, when they select the address to send from. How do I mirror this in the Interop? Thanks! (My Original Question): I developed a small C# program to send email using the Outlook 2007 interop. The client required that the mail not be send using the default account - they had a secondary account they needed used. No problem - I used the Microsoft.Office.Interop.Outlook.Account class to access the availabled accounts, and choose the correct one. Now, it turns out they need this to work in Outlook 2003. Of course, the Account class doesn't exist in the Outlook interop 11.0. How can I achieve the same thing with Outlook 2003? Thanks in advance.

  • SQL Exception: "Impersonate Session Security Context" cannot be called in this batch because a simul

    - by kasey
    When opening a connection to SQL Server 2005 from our web app, we occasionally see this error: "Impersonate Session Security Context" cannot be called in this batch because a simultaneous batch has called it. We use MARS and connection pooling. The exception originates from the following piece of code: protected SqlConnection Open() { SqlConnection connection = new SqlConnection(); connection.ConnectionString = m_ConnectionString; if (connection != null) { try { connection.Open(); if (m_ExecuteAsUserName != null) { string sql = Format("EXECUTE AS LOGIN = {0};", m_ExecuteAsUserName); ExecuteCommand(connection, sql); } } catch (Exception exception) { connection.Close(); connection = null; } } return connection; } I found an MS Connect article which suggests that the error is caused when a previous command has not yet terminated before the EXECUTE AS LOGIN command is sent. Yet how can this be if the connection has only just been opened? Could this be something to do with connection pooling interacting strangely with MARS? UPDATE: For the short-term we have implemented a workaround by clearing out the connection pool whenever this happens, to get rid of the bad connection, as it otherwise keeps getting handed back to various users. (Not too bad as this only happens a couple of times a day.) But if anyone has any further ideas, we are still looking out for a real solution...

  • SubmitChanges doesn't save but removes inserts from change set, no errors

    - by winston schröder
    Hi Everybody, I have a deeper question regarding debug functionality of Linq to Sql SubmitChanges() Function. I want to save a record in a table of a locally cached db (localdbcache: server SqlExpress 2008 client SqlCE). Before calling SubmitChanges I can find the new item via DataContext.GetChangeSet(). After calling Submit Changes, the items to insert have been removed from the ChangeSet. (That's what this function is supposed to do.) There are no Changes Conflicts and no error in the db's log output. No Exception at all. The table's Count stays at the same value. if ((e.Parameter == null) || (!e.Parameter.GetType().Equals(typeof(LibDB.Client.Vehicles)))) return; LibDB.Client.Vehicles tmp = e.Parameter as LibDB.Client.Vehicles; try { ChangeSet cs = this._dc.GetChangeSet(); if ((tmp == null) || (this._dc == null)) return; if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 0) this._dc.Vehicles.InsertOnSubmit(tmp); else if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 1) this._dc.Vehicles.Attach(tmp, true); else return; using (TransactionScope ts = new TransactionScope()) { try { this._dc.SubmitChanges(); //this._dc.Refresh(RefreshMode.OverwriteCurrentValues, this._dc.Vehicles); } catch (Exception ex) { Console.WriteLine(ex.Message); } } if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 1) MessageBox.Show("Vehicle not saved."); this.vehSelector.ResetLayout(); } I would appreciate any help since I'm loosing hope to find any error, Thanks in Advance Winston

  • Creating generic list of instances of a class.

    - by Jim Branson
    I have several projects where I build a dictionary from a small class. I'm using C# 2008, Visual studio 2008 and .net 3.5 This is the code: namespace ReportsTest { class Junk { public static Dictionary<string, string> getPlatKeys() { Dictionary<string, string> retPlatKeys = new Dictionary<string, string>(); SqlConnection conn = new SqlConnection("Data Source=JB55LTARL;Initial Catalog=HldiReports;Integrated Security=True"); SqlDataReader Dr = null; conn.Open(); SqlCommand cmnd = new SqlCommand("SELECT Make, Series, RedesignYear, SeriesName FROM CompPlatformKeys", conn); Dr = cmnd.ExecuteReader(); while (Dr.Read()) { utypPlatKeys rec = new utypPlatKeys(Dr); retPlatKeys.Add(rec.Make + rec.Series + rec.RedesignYear, rec.SeriesName); } conn = null; Dr = null; return retPlatKeys; } } public class utypPlatKeys { public string Make { get; set; } public string Series { get; set; } public string RedesignYear { get; set; } public string SeriesName { get; set; } public utypPlatKeys(SqlDataReader dr) { this.Make = dr.GetInt16(dr.GetOrdinal("Make")).ToString("D3"); this.Series = dr.GetInt16(dr.GetOrdinal("Series")).ToString("D3"); this.RedesignYear = dr.GetInt16(dr.GetOrdinal("RedesignYear")).ToString(); this.SeriesName = dr["SeriesName"].ToString(); } } } The immediate window shows all of the entries in retPlatKeys and if you hover over retPlatKeys after loading it indicates the number of elements like this: "retPlatKeys| Count = 923 which is correct. I went to create a new project using this pattern only now the immediate window says retPlatKeys is out of scope and hovering over retPlatKeys after loading I get something like retPlatKeys|0x0000000002578900. Any help is greatly appreciated.

  • Enum "does not have a no-arg default constructor" with Jaxb and cxf

    - by Dave
    A client is having an issue running java2ws on some of their code, which uses & extends classes that are consumed from my SOAP web services. Confused yet? :) I'm exposing a SOAP web service (JBoss5, Java 6). Someone is consuming that web service with Axis1 and creating a jar out of it with the data types and client stubs. They are then defining their own type, which extends one of my types. My type contains an enumeration. class MyParent { private MyEnumType myEnum; // getters, settters for myEnum; } class TheirChild extends MyParent { ... } When they are running java2ws on their code (which extends my class), they get Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions net.foo.bar.MyEnuMType does not have a no-arg default constructor. this problem is related to the following location: at net.foo.bar.MyEnumType at public net.foo.bar.MyEnumType net.foo.bar.MyParent.getMyEnum() The enum I've defined is below. This is now how it comes out after being consumed, but it's how I have it defined on the app server: @XmlType(name = "MyEnumType") @XmlEnum public enum MyEnumType { Val1("Val1"), Val2("Val2") private final String value; MyEnumType(String v) { value = v; } public String value() { return value; } public static MyEnumType fromValue(String v) { if (v == null || v.length() == 0) { return null; } if (v.equals("Val1")) { return MyEnumType.Val1; } if (v.equals("Val2")) { return MyEnumType.Val2; } return null; } } I've seen things online and other posts, like (this one) regarding Jaxb's inability to handle Lists or things like that, but I'm baffled about my enum. I'm pretty sure you can't have a default constructor for an enum (well, at least a public no-arg constructor, Java yells at me when I try), so I'm not sure what makes this error possible. Any ideas? Also, the "2 counts of IllegalAnnotationsExceptions" may be because my code actually has two enums that are written similarly, but I left them out of this example for brevity.

  • Algorithm for converting hierarchical flat data (w/ ParentID) into sorted flat list w/ indentation l

    - by eagle
    I have the following structure: MyClass { guid ID guid ParentID string Name } I'd like to create an array which contains the elements in the order they should be displayed in a hierarchy (e.g. according to their "left" values), as well as a hash which maps the guid to the indentation level. For example: ID Name ParentID ------------------------ 1 Cats 2 2 Animal NULL 3 Tiger 1 4 Book NULL 5 Airplane NULL This would essentially produce the following objects: // Array is an array of all the elements sorted by the way you would see them in a fully expanded tree Array[0] = "Airplane" Array[1] = "Animal" Array[2] = "Cats" Array[3] = "Tiger" Array[4] = "Book" // IndentationLevel is a hash of GUIDs to IndentationLevels. IndentationLevel["1"] = 1 IndentationLevel["2"] = 0 IndentationLevel["3"] = 2 IndentationLevel["4"] = 0 IndentationLevel["5"] = 0 For clarity, this is what the hierarchy looks like: Airplane Animal Cats Tiger Book I'd like to iterate through the items the least amount of times possible. I also don't want to create a hierarchical data structure. I'd prefer to use arrays, hashes, stacks, or queues. The two objectives are: Store a hash of the ID to the indentation level. Sort the list that holds all the objects according to their left values. When I get the list of elements, they are in no particular order. Siblings should be ordered by their Name property. Update: This may seem like I haven't tried coming up with a solution myself and simply want others to do the work for me. However, I have tried coming up with three different solutions, and I've gotten stuck on each. One reason might be that I've tried to avoid recursion (maybe wrongly so). I'm not posting the partial solutions I have so far since they are incorrect and may badly influence the solutions of others.

  • OJB Reference Descriptor 1:0 relationship? Should I set auto-retrieve to false?

    - by godzillasdm
    Hi, I am having an issue while using Apache OJB with Spring 2 inside my web app. I'm using OJB reference-descriptor with 2 foreign key properties. I have an object A (parent) and object B (referenced object). The thing is, for an object A, there may or may not be an object B. In the case where there is no object B to go with Object A, the object B seems to be instantiated (through Spring?) anyways. However, I am unable to access object B's members. Whenever I test if Object B == null, it always returns false even though there is no matching value in the database. Since this Object is never null, I figured I can test the object's member like so: if( objectb.getDocumentNumber == null) { return false; } However, I get an exception in the jsp: javax.servlet.jsp.el.ELException: An error occurred while getting property "documentNumber" from an instance class org.sample.pojo.Objectb$$EnhancerByCGLIB$$78022a2 and this exception in the debugger when it's creating the objectB: com.sun.jdi.InvocationException occurred invoking method. I am guessing that the reference-descriptor must be a 1:1+ relationship, instead of a 1:0+ relationship. I was wondering if I should set the property 'auto-retrieve' to false, and then use the PersistenceBroker.retrieveAllReferences(Object obj); method as directed. However, this method's return value is 'void', so I am guessing that Spring somehow creates, and sets the reference class for me. (Returning me back to the same issue I'm having.) I will need a way to test whether the reference object exists first. If not, don't call this retrieveAllReferences method, but I don't see how. Am I going about this all wrong? Does reference-descriptor not allow 1:0 relations? Any work around to my problem? Your suggestions are greatly appreciated!

  • AS3 : RegExp exec method in loop problem

    - by Boun
    Hi everyone, I need some help about RegExp in AS3. I have a simple pattern : patternYouTube = new RegExp ( "v(?:\/|=)([A-Z0-9_-]+)", "gi" ); This pattern is looking for the youTube id video. For example : var tmpUrl : String; var result : Object; var toto : Array = new Array(); toto = [http://www.youtube.com/v/J-vCxmjCm-8&autoplay=1, http://www.youtube.com/v/xFTRnE1WBmU&autoplay=1]; var i : uint; for ( i = 0 ; i < toto.length ; i++) { tmpUrl = toto[i]; result = patternYouTube.exec ( tmpUrl ); if ( result.length != 0 && result != null ) { trace(result); } } When i == 0, it works perfectly. Flash returns me : v/J-vCxmjCm-8,J-vCxmjCm-8 When i == 1, it fails. Flash returns me : null When I revert the two strings in my array such as : toto = [ http://www.youtube.com/v/xFTRnE1WBmU&autoplay=1, http://www.youtube.com/v/J-vCxmjCm-8&autoplay=1 ]; When i == 0, it works perfectly : Flash returns me : xFTRnE1WBmU When i == 1, it fails : Flash returns me : null Do you have any idea about the problem in the loop ?

  • (1 2 3 . #<void>)- heapsort

    - by superguay
    Hello everybody: I tried to implement a "pairing heap" with all the regular operations (merge, delete-min etc.), then I've been requested to write a function that would sort a list using my newly constructed heap implementation. Unfortunately it seems that someting goes wrong... Here's the relevant code: (define (heap-merge h1 h2) (cond ((heap-empty? h1) h2) ((heap-empty? h2) h1) (else (let ((min1 (heap-get-min h1)) (min2 (heap-get-min h2))) (if ((heap-get-less h1) min1 min2) (make-pairing-heap (heap-get-less h1) min1 (cons h2 (heap-get-subheaps h1))) (make-pairing-heap (heap-get-less h1) min2 (cons h1 (heap-get-subheaps h2)))))))) (define (heap-insert element h) (heap-merge (make-pairing-heap (heap-get-less h) element '()) h)) (define (heap-delete-min h) (define (merge-in-pairs less? subheaps) (cond ((null? subheaps) (make-heap less?)) ((null? (cdr subheaps)) (car subheaps)) (else (heap-merge (heap-merge (car subheaps) (cadr subheaps)) (merge-in-pairs less? (cddr subheaps)))))) (if (heap-empty? h) (error "expected pairing-heap for first argument, got an empty heap ") (merge-in-pairs (heap-get-less h) (heap-get-subheaps h)))) (define (heapsort l less?) (let aux ((h (accumulate heap-insert (make-heap less?) l))) (if (not (heap-empty? h)) (cons (heap-get-min h) (aux (heap-delete-min h)))))) And these are some selectors that may help you to understand the code: (define (make-pairing-heap less? min subheaps) (cons less? (cons min subheaps))) (define (make-heap less?) (cons less? '())) (define (heap-get-less h) (car h)) (define (heap-empty? h) (if (null? (cdr h)) #t #f)) Now lets get to the problem: When i run 'heapsort' it returns the sorted list with "void", as you can see: (heapsort (list 1 2 3) <) (1 2 3 . #)..HOW CAN I FIX IT?

  • Scope of Connection Object for a Website using Connection Pooling (Local or Instance)

    - by Danny
    For a web application with connection polling enabled, is it better to work with a locally scoped connection object or instance scoped connection object. I know there is probably not a big performance improvement between the two (because of the pooling) but would you say that one follows a better pattern than the other. Thanks ;) public class MyServlet extends HttpServlet { DataSource ds; public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } void SomeWork(String sql) { Connection conn = null; try { conn = ds.getConnection(); // execute some sql ..... } finally { if(conn != null) { conn.close(); // return to pool } } } } Or public class MyServlet extends HttpServlet { DataSource ds; Connection conn;* public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { try { conn = ds.getConnection(); SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } finally { if(conn != null) { conn.close(); // return to pool } } } void SomeWork(String sql) { // execute some sql ..... } }
