• iphone: memory problems after refactor

  - by agilpwc

  I had a NIB with several view controllers in it. I modified the code and used Interface Builder decomose interface to get all the view controllers in their own Nib. But now with empty core data database, I'm getting "message sent to deallocated instance" errors. Here is the code flow: From the RootViewController this is called: if (self.dogController == nil) { DogViewController *controller = [[DogViewController alloc] initWithNibName:@"DogViewController" bundle:nil]; self.dogController = controller; [controller release]; } self.dogController.managedObjectContext = self.managedObjectContext; [self.navigationController pushViewController:self.dogController animated:YES]; Then in a dogController a button is pressed to insert a new object and the following code is excuted and the error hits on the save, according to the trace NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext]; NSEntityDescription *entity = [[self.fetchedResultsController fetchRequest] entity]; NSManagedObject *newManagedObject = [NSEntityDescription insertNewObjectForEntityForName:[entity name] inManagedObjectContext:context]; // If appropriate, configure the new managed object. [newManagedObject setValue:[NSDate date] forKey:@"birthDate"]; [newManagedObject setValue:@"-" forKey:@"callName"]; // Save the context. NSError *error = nil; if (![context save:&error]) { Then the error produced in the console is * -[JudgeViewController numberOfSectionsInTableView:]: message sent to deallocated instance 0x598e580 I'm racking my brain for hours and I can't figure out where my minor changes made something messed up. Any ideas?

• Iphone Core Data Internal Inconsistency

  - by kiyoshi

  This question has something to do with the question I posted here: http://stackoverflow.com/questions/1230858/iphone-core-data-crashing-on-save however the error is different so I am making a new question. Now I get this error when trying to insert new objects into my managedObjectContext: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '"MailMessage" is not a subclass of NSManagedObject.' But clearly it is: @interface MailMessage : NSManagedObject { .... And when I run this code: NSManagedObjectModel *managedObjectModel = [[self.managedObjectContext persistentStoreCoordinator] managedObjectModel]; NSEntityDescription *entity =[[managedObjectModel entitiesByName] objectForKey:@"MailMessage"]; NSManagedObject *newObject = [[NSManagedObject alloc] initWithEntity:entity insertIntoManagedObjectContext:self.managedObjectContext]; It runs fine when I do not present an MFMailComposeViewController, but if I run this code in the - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { method, it throws the above error when creating the newObject variable. The entity object when I use print object produces the following: (<NSEntityDescription: 0x1202e0>) name MailMessage, managedObjectClassName MailMessage, renamingIdentifier MailMessage, isAbstract 0, superentity name (null), properties { in both cases, so I don't think the managedObjectContext is completely invalid. I have no idea why it would say MailMessage is not a subclass of NSManagedObject at that point, and not at the other. Any help would be appreciated, thanks in advance.

• jsf custom control strange behaviour

  - by Cristian Boariu

  hi, I have a jsf custom control which contains this: <rich:column> <c:if test="#{not empty columnTitle}"> <f:facet name="header"> <rich:spacer/> </f:facet> </c:if> <s:link view="#{view}" value="#{messages['edit']}" propagation="#{propagation}"> <f:param name="${paramName}" value="${paramValue}"/> </s:link> &#160; <h:commandLink action="#{entityHome.removeMethodName(entity)}" value="#{messages['remove']}"/> </rich:column> You see that command link action. I want it to call an action like this: action="#{documentHome.removeProperty(property)"} Well, in order to do this i call the control like: <up:columnDetails view="/admin/property.xhtml" columnTitle="yes" entity="#{property}" paramValue="#{property.propertyId}" propagation="nest" entityHome="documentHome" removeMethodName="removeProperty"/> So, i hardcode entityHome and removeMethodName. Well an error is firing. Caused by javax.servlet.ServletException with message: "#{entityHome.removeMethodName(entity)}: javax.el.MethodNotFoundException It seems that it cannot interpret "removeMethodName". If i print entityHome or removeMethodName it correctly shows the values i pass. But i think jsf has an error like not beeing able to "believe" that after an object.something, that something can be a parameter... Can anyone guide me...?

• Using an objects date (without time) for a table header instead of an objects date and time (iphone)

  - by billywilliamton

  I've been working on an iphone project and have run into an issue. Currently In the table view where it displays all the objects, I use headers based on the objects datePerformed field. The only problem is that my code apparently creates a header that contains both the date and time resulting in objects not being grouped solely by their date as I intended, but rather based on their date and time. I'm not sure if it matters, but when an object is created I use a date picker to pick the date, but not the time. I was wondering if anyone could give me any suggestions or advice. Here is the code where i set up the fetchedResultsController - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) { return fetchedResultsController; } // Create and configure a fetch request with the Exercise entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Exercise" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // Create the sort descriptors array using date and name NSSortDescriptor *dateDescriptor = [[NSSortDescriptor alloc] initWithKey:@"datePerformed" ascending:NO]; NSSortDescriptor *nameDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:dateDescriptor, nameDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Create and initialize the fetch results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"datePerformed" cacheName:@"Root"]; self.fetchedResultsController = aFetchedResultsController; fetchedResultsController.delegate = self; // Memory management calls [aFetchedResultsController release]; [fetchRequest release]; [dateDescriptor release]; [nameDescriptor release]; [sortDescriptors release]; return fetchedResultsController; } Here's where I set up the table header properties - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { // Display the exercise' date as section headings. return [[[fetchedResultsController sections] objectAtIndex:section] name]; } Any suggestions welcome. Thanks for your time. -Billy Williamton

• Entities used to serialize data have changed. How can the serialized data be upgraded for the new entities?

  - by i8abug

  Hi, I have a bunch of simple entity instances that I have serialized to a file. In the future, I know that the structure of these entities (ie, maybe I will rename Name to Header or something). The thing is, I don't want to lose the data that I have saved in all these old files. What is the proper way to either load the data from the old entities into new entities upgrade the old files so that they can be used with new entities Note: I think I am stuck with binary serialization, not xml serialization. Thanks in advance! Edit: So I have an answer for the case I have described. I can use a dataContractSerializer and do something like [DataMember("bar")] private string foo; and change the name in the code and keep the same name that was used for serialization. But what about the following additional cases: The original entity has new members which can be serialized Some serialized members that were in the original entity are removed Some members have actually changed in function (suppose that the original class had a FirstName and LastName member and it has been refactored to have only a FullName member which combines the two) To handle these, I need some sort of interpreter/translator deserialization class but I have no idea what I should use

• Work with function references

  - by Ockonal

  Hello, I have another one question about functions reference. For example, I have such definition: typedef boost::function<bool (Entity &handle)> behaviorRef; std::map< std::string, ptr_vector<behaviorRef> > eventAssociation; The first question is: how to insert values into such map object? I tried: eventAssociation.insert(std::pair< std::string, ptr_vector<behaviorRef> >(eventType, ptr_vector<behaviorRef>(callback))); But the error: no matching function for call to ‘boost::ptr_vector<boost::function<bool(Entity&)> >::push_back(Entity::behaviorRef&)’ And I undersatnd it, but can't make workable code. The second question is how to call such functions? For example, I have one object of behaviorRef, how to call it with boost::bind with passing my own values?

• Question about architecting asp.net mvc application ?

  - by Misnomer

  I have read little bit about architecture and also patterns in order to follow the best practices. So this is the architecture we have and I wanted to know what you think of it and any proposed changes or improvements to it - Presentation Layer - Contains all the views,controllers and any helper classes that the view requires also it containes the reference to Model Layer and Business Layer. Business Project - Contains all the business logic and validation and security helper classes that are being used by it. It contains a reference to DataAccess Layer and Model Layer. Data Access Layer - Contains the actual queries being made on the entity classes(CRUD) operations on the entity classes. It contains reference to Model Layer. Model Layer - Contains the entity framework model,DTOs,Enums.Does not really have a reference to any of the above layers. What are your thoughts on the above architecture ? The problem is that I am getting confused by reading about like say the repository pattern, domain driven design and other design patterns. The architecture we have although not that strict still is relatively alright I think and does not really muddle things but I maybe wrong. I would appreciate any help or suggestions here. Thanks !

• Using the JPA Criteria API, can you do a fetch join that results in only one join?

  - by Shaun

  Using JPA 2.0. It seems that by default (no explicit fetch), @OneToOne(fetch = FetchType.EAGER) fields are fetched in 1 + N queries, where N is the number of results containing an Entity that defines the relationship to a distinct related entity. Using the Criteria API, I might try to avoid that as follows: CriteriaBuilder builder = entityManager.getCriteriaBuilder(); CriteriaQuery<MyEntity> query = builder.createQuery(MyEntity.class); Root<MyEntity> root = query.from(MyEntity.class); Join<MyEntity, RelatedEntity> join = root.join("relatedEntity"); root.fetch("relatedEntity"); query.select(root).where(builder.equals(join.get("id"), 3)); The above should ideally be equivalent to the following: SELECT m FROM MyEntity m JOIN FETCH myEntity.relatedEntity r WHERE r.id = 3 However, the criteria query results in the root table needlessly being joined to the related entity table twice; once for the fetch, and once for the where predicate. The resulting SQL looks something like this: SELECT myentity.id, myentity.attribute, relatedentity2.id, relatedentity2.attribute FROM my_entity myentity INNER JOIN related_entity relatedentity1 ON myentity.related_id = relatedentity1.id INNER JOIN related_entity relatedentity2 ON myentity.related_id = relatedentity2.id WHERE relatedentity1.id = 3 Alas, if I only do the fetch, then I don't have an expression to use in the where clause. Am I missing something, or is this a limitation of the Criteria API? If it's the latter, is this being remedied in JPA 2.1 or are there any vendor-specific enhancements? Otherwise, it seems better to just give up compile-time type checking (I realize my example doesn't use the metamodel) and use dynamic JPQL TypedQueries.

• Android while getting HTTP response to file how to know it wasn't fully loaded?

  - by Stan

  I'm using this approach to store a big-sized response from server to parse it later: final HttpClient client = new DefaultHttpClient(new BasicHttpParams()); final HttpGet mHttpGetRequest = new HttpGet(strUrl); mHttpGetRequest.setHeader("Content-Type", "application/x-www-form-urlencoded"); FileOutputStream fos = null; try { final HttpResponse response = client.execute(mHttpGetRequest); final StatusLine statusLine = response.getStatusLine(); lastHttpErrorCode = statusLine.getStatusCode(); lastHttpErrorMsg = statusLine.getReasonPhrase(); if (lastHttpErrorCode == 200) { HttpEntity entity = response.getEntity(); fos = new FileOutputStream(reponseFile); entity.writeTo(fos); entity.consumeContent(); fos.flush(); } } catch (ClientProtocolException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); return null; } catch (final ParseException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); return null; } catch (final UnknownHostException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); return null; } catch (IOException e) { e.printStackTrace(); lastHttpErrorMsg = e.toString(); } finally{ if (fos!=null) try{ fos.close(); } catch (IOException e){} } now how could I ensure the response was completely received and thus saved to file? Assume client's device lost Internet connection while this code was running. So the app received only some part of real response. And I'm pretty sure it happens cuz I got parsing exceptions like "tag not closed", "unexpected end of file" etc. So I need to detect somehow this situation to prevent code from parsing partial response but can't see how. Is it possible at all and how to do it? Or has it has to raise IOException in such cases?

• Mapping many-to-many association table with extra column(s)

  - by user635524

  My database contains 3 tables: User and Service entities have many-to-many relationship and are joined with the SERVICE_USER table as follows: USERS - SERVICE_USER - SERVICES SERVICE_USER table contains additional BLOCKED column. What is the best way to perform such a mapping? These are my Entity classes @Entity @Table(name = "USERS") public class User implements java.io.Serializable { private String userid; private String email; @Id @Column(name = "USERID", unique = true, nullable = false,) public String getUserid() { return this.userid; } .... some get/set methods } @Entity @Table(name = "SERVICES") public class CmsService implements java.io.Serializable { private String serviceCode; @Id @Column(name = "SERVICE_CODE", unique = true, nullable = false, length = 100) public String getServiceCode() { return this.serviceCode; } .... some additional fields and get/set methods } I followed this example http://giannigar.wordpress.com/2009/09/04/m ... using-jpa/ Here is some test code: User user = new User(); user.setEmail("e2"); user.setUserid("ui2"); user.setPassword("p2"); CmsService service= new CmsService("cd2","name2"); List<UserService> userServiceList = new ArrayList<UserService>(); UserService userService = new UserService(); userService.setService(service); userService.setUser(user); userService.setBlocked(true); service.getUserServices().add(userService); userDAO.save(user); The problem is that hibernate persists User object and UserService one. No success with the CmsService object I tried to use EAGER fetch - no progress Is it possible to achieve the behaviour I'm expecting with the mapping provided above? Maybe there is some more elegant way of mapping many to many join table with additional column?

• NSPredicate (Core Data fetch) to filter on an attribute value being present in a supplied set (list)

  - by starbaseweb

  I'm trying to create a fetch predicate that is the analog to the SQL "IN" statement, and the syntax to do so with NSPredicate escapes me. Here's what I have so far (the relevant excerpt from my fetching routine): NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; NSEntityDescription *entity = [NSEntityDescription entityForName: @"BodyPartCategory" inManagedObjectContext:_context]; [request setEntity:entity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(name IN %@)", [RPBodyPartCategory defaultBodyPartCategoryNames]]; [request setPredicate:predicate]; The entity "BodyPartCategory" has a string attribute "name". I have a list of names (just NSString objects) in an NSArray as returned by: [RPBodyPartCategory defaultBodyPartCategoryNames] So let's say that array has string such as {@"Liver", @"Kidney", @"Thyroid"} ... etc. I want to fetch all 'BodyPartCategory' instances whose name attribute matches one of the strings in the set provided (technically NSArray but I can make it an NSSet). In SQL, this would be something like: SELECT * FROM BodyPartCategories WHERE name IN ('Liver', 'Kidney', 'Thyroid') I've gone through various portions of the Predicate Programming Guide, but I don't see this simple use case covered. Pointers/help much appreciated!

• How to use JOIN using Hibernate's session.createSQLQuery()

  - by javauser71

  Hi All, I have two Entity (tables) - Employee & Project. An Employee can have multiple Projects. Project table's CREATOR_ID field refers to Employee table's ID field. Employee entity maintains a list of Project. Using EntityManager following query works fine - "entityManager.createQuery("select e from EmployeeDTO e, ProjectDTO p where p.id = ?1 and p.creator.id=e.id"); But since I have the LAZY association relationship, I get error: "Could not initialize proxy - no Session" if I try to access Project info from Employee entity. This is expected and so I am using Hibernate's Session to create query as shown below. Session session = HibernateUtil.getSessionFactory().openSession(); org.hibernate.Query q = session.createSQLQuery("SELECT E FROM EMPLOYEE_TAB E, PROJECT_TAB P WHERE P.ID = " + projectId + " AND P.CREATOR_ID = E.ID") .addEntity("EmployeeDTO ", EmployeeDTO.class) .addEntity("ProjectDTO", ProjectDTO.class); But I get error like: "Column 'E' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification..." Can anyone suggest what will be the right JOIN syntax for such case? If I use ("SELECT * FROM EMPLOYEE_TAB E, ........") - it gives other error: "java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to com.im.server.dto.EmployeeDTO". Thanks in advance.

• '??' Not a valid unicode character, but in the unicode character set?

  - by Steve Cotner

  Short story: I can't get an entity like '𠂉' to store in a MySQL database, either by using a text field in a Ruby on Rails app (with default UTF-8 encoding) or by inputting it directly with a MySQL GUI app. As far as I can tell, all Chinese characters and radicals can be entered into the database without problem, but not these rarely typed 'character components.' The character mentioned above is unicode U+20089 and html entity &#131209; I can get it to display on the page by entering <html>&#131209;</html> and removing html escaping, but I would like to store it simply as the unicode character and keep the html escaping in place. There are many other Chinese 'components' (parts of full characters, generally consisting of 2 or 3 strokes) that cause the same problem. According to this page, the character mentioned is in the UTF-8 charset: http://www.fileformat.info/info/unicode/char/20089/charset_support.htm But on the neighboring '...20089/index.htm' page, there's an alert saying it's not a valid unicode character. For reference, that entity can be found in Mac OS X by searching through the character palette (international menu, "Show Character Palette"), searching by radical, and looking under the '?' radical. Apologies if this is too open-ended... can a character like this be stored in a UTF-8-based database? How is this character both supported and unsupported, both present in the character set and not valid?

• UITabbleView Sections /cellForRowAtIndexPath method

• Lucene - querying with long strings

  - by Mikos

  I have an index, with a field "Affiliation", some example values are: "Stanford University School of Medicine, Palo Alto, CA USA", "Institute of Neurobiology, School of Medicine, Stanford University, Palo Alto, CA", "School of Medicine, Harvard University, Boston MA", "Brigham & Women's, Harvard University School of Medicine, Boston, MA" "Harvard University, Cambridge MA" and so on... (the bottom-line being the affiliations are written in multiple ways with no apparent consistency) I query the index on the affiliation field using say "School of Medicine, Stanford University, Palo Alto, CA" (with QueryParser) to find all Stanford related documents, I get a lot of false +ves, presumably because of the presence of School of Medicine etc. etc. (note: I cannot use Phrase query because of variability in the way affiliation is constructed) I have tried the following: Use a SpanNearQuery by splitting the search phrase with a whitespace (here I get no results!) Tried boosting (using ^) by splitting with the comma and boosting the last parts such as "Palo Alto CA" with a much higher boost than the initial phrases. Here I still get lots of false +ves. Any suggestions on how to approach this? If SpanNearQuery the way to go, Any ideas on why I get 0 results?

• 401 Using Multiple Authentication methods IE 10 only

  - by jon3laze

  I am not sure if this is more of a coding issue or server setup issue so I've posted it on stackoverflow and here... On our production site we've run into an issue that is specific to Internet Explorer 10. I am using jQuery doing an ajax POST to a web service on the same domain and in IE10 I am getting a 401 response, IE9 works perfectly fine. I should mention that we have mirrored code in another area of our site and it works perfectly fine in IE10. The only difference between the two areas is that one is under a subdomain and the other is at the root level. www.my1stdomain.com vs. portal.my2nddomain.com The directory structure on the server for these are: \my1stdomain\webservice\name\service.aspx \portal\webservice\name\service.aspx Inside of the \portal\ and \my1stdomain\ folders I have a page that does an ajax call, both pages are identical. $.ajax({ type: 'POST', url: '/webservice/name/service.aspx/function', cache: false, contentType: 'application/json; charset=utf-8', dataType: 'json', data: '{ "json": "data" }', success: function() { }, error: function() { } }); I've verified permissions are the same on both folders on the server side. I've applied a workaround fix of placing the <meta http-equiv="X-UA-Compatible" value="IE=9"> to force compatibility view (putting IE into compatibility mode fixes the issue). This seems to be working in IE10 on Windows 7, however IE 10 on Windows 8 still sees the same issue. These pages are classic asp with the headers that are being included, also there are no other meta tags being used. The doctype is being specified as <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//" "http://www.w3.org/TR/html4/loose.dtd"> on the portal page and <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> on the main domain. UPDATE1 I used Microsoft Network Monitor 3.4 on the server to capture the request. I used the following filter to capture the 401: Property.HttpStatusCode.StringToNumber == 401 This was the response - Http: Response, HTTP/1.1, Status: Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authetication Methods, see frame details ProtocolVersion: HTTP/1.1 StatusCode: 401, Unauthorized Reason: Unauthorized - ContentType: application/json; charset=utf-8 - MediaType: application/json; charset=utf-8 MainType: application/json charset: utf-8 Server: Microsoft-IIS/7.0 jsonerror: true - WWWAuthenticate: Negotiate - Authenticate: Negotiate WhiteSpace: AuthenticateData: Negotiate - WWWAuthenticate: NTLM - Authenticate: NTLM WhiteSpace: AuthenticateData: NTLM XPoweredBy: ASP.NET Date: Mon, 04 Mar 2013 21:13:39 GMT ContentLength: 105 HeaderEnd: CRLF - payload: HttpContentType = application/json; charset=utf-8 HTTPPayloadLine: {"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"} The thing here that really stands out is Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authentication Methods With this I'm still confused as to why this only happens in IE10 if it's a permission/authentication issue.

• Per-pixel per-component alpha blending in Windows

  - by Crend King

  I have a 24-bit bitmaps with R, G, B color channels and a 24-bit bitmap with R, G, B alpha channels. I want to alpha blend the first bitmap to a HDC in GDI or RenderTarget in Direct2D with the alpha channels respectively. For example, suppose for one pixel, the bitmap color is (192, 192, 192), the HDC color is (0, 255, 255) and the alpha channels are (30, 40, 50). The final HDC color should be (22, 245, 242). I know I can BitBlt the HDC to a memory HDC first, do alpha blending by manually calculating the color of each pixel and finally BitBlt back. I just want to avoid the additional blitting and leave APIs do their job (faster since they are in kernel space). The first idea comes to my mind is to split the source bitmap into 3 red-only, green-only and blue-only 8-bit bitmaps, do normal alpha blending, then composite the 3 output bitmaps into the HDC. But I don't find a way to do the splitting and composition natively in Windows (would Direct2D layer help?). Also, the splitting and compositing may require many additional copying. The performance overhead would be too high. Or maybe do the alpha blending in 3 passes. Each pass apply the blending for one channel, while maintaining the other 2 unchanged. Thanks for any comment. EDIT: I found this question, and the answer should be good reference to this problem. However, besides AC_SRC_OVER, there is no other blending operation supported. Why don't Microsoft improve their API?

• SimpleXMLElement (PHP) throwing error on XML root attributes

  - by Greg

  I am working on a project that will take XML data submitted through a textarea input in a form then extract the data and throw it into a database. I am getting errors about the attribute in the root field of my XML (it is the same schema each time, but with different values). If i remove these attributes it works fine, but I don't want to have to remove these attributes each I time I go to send the data to the script. here is a sample of my data and code I am using (the part that is giving me errors): <raid generatedFrom="HeadCount" version="1.7.4"> --snip-- </raid> If I post the data as such, i get errors such as: Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : AttValue: " or ' expected in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : attributes construct error in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : Couldn't find end of Start Tag raid line 1 in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : Extra content at the end of the document in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: <raid generatedFrom=\"HeadCount\" version=\"1.7.4\"> in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php:13 Stack trace: #0 /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php(13): SimpleXMLElement->__construct('<raid generated...') #1 {main} thrown in /home/content/g/V/i/gViscardi/html/guilds/sanctum/headcount.php on line 13 If I remove the attributes from the root node then it works fine with no errors.

• Saving child collections with NHibernate

  - by Ben

  Hi, I am in the process or learning NHibernate so bare with me. I have an Order class and a Transaction class. Order has a one to many association with transaction. The transaction table in my database has a not null constraint on the OrderId foreign key. Order class: public class Order { public virtual Guid Id { get; set; } public virtual DateTime CreatedOn { get; set; } public virtual decimal Total { get; set; } public virtual ICollection<Transaction> Transactions { get; set; } public Order() { Transactions = new HashSet<Transaction>(); } } Order Mapping: <class name="Order" table="Orders"> <cache usage="read-write"/> <id name="Id"> <generator class="guid"/> </id> <property name="CreatedOn" type="datetime"/> <property name="Total" type="decimal"/> <set name="Transactions" table="Transactions" lazy="false" inverse="true"> <key column="OrderId"/> <one-to-many class="Transaction"/> </set> Transaction Class: public class Transaction { public virtual Guid Id { get; set; } public virtual DateTime ExecutedOn { get; set; } public virtual bool Success { get; set; } public virtual Order Order { get; set; } } Transaction Mapping: <class name="Transaction" table="Transactions"> <cache usage="read-write"/> <id name="Id" column="Id" type="Guid"> <generator class="guid"/> </id> <property name="ExecutedOn" type="datetime"/> <property name="Success" type="bool"/> <many-to-one name="Order" class="Order" column="OrderId" not-null="true"/> Really I don't want a bidirectional association. There is no need for my transaction objects to reference their order object directly (I just need to access the transactions of an order). However, I had to add this so that Order.Transactions is persisted to the database: Repository: public void Update(Order entity) { using (ISession session = NHibernateHelper.OpenSession()) { using (ITransaction transaction = session.BeginTransaction()) { session.Update(entity); foreach (var tx in entity.Transactions) { tx.Order = entity; session.SaveOrUpdate(tx); } transaction.Commit(); } } } My problem is that this will then issue an update for every transaction on the order collection (regardless of whether it has changed or not). What I was trying to get around was having to explicitly save the transaction before saving the order and instead just add the transactions to the order and then save the order: public void Can_add_transaction_to_existing_order() { var orderRepo = new OrderRepository(); var order = orderRepo.GetById(new Guid("aa3b5d04-c5c8-4ad9-9b3e-9ce73e488a9f")); Transaction tx = new Transaction(); tx.ExecutedOn = DateTime.Now; tx.Success = true; order.Transactions.Add(tx); orderRepo.Update(order); } Although I have found quite a few articles covering the set up of a one-to-many association, most of these discuss retrieving of data and not persisting back. Many thanks, Ben

• HQL over ternary map with subcollection

  - by Diego Mijelshon

  I'm stuck with a query I need to write. Given the following model: public class A : Entity<Guid> { public virtual IDictionary<B, C> C { get; set; } } public class B : Entity<Guid> { } public class C : Entity<Guid> { public virtual int Data1 { get; set; } public virtual ICollection<D> D { get; set; } } public class D : Entity<Guid> { public virtual int Data2 { get; set; } } I need to get a list of A instances that have a D containing some data for the specified B (parameter) In the object model, that would be: listOfA.Where(a => a.C[b].D.Any(d => d.Data2 == 0)) But I wasn't able to write a working HQL. I'm able to write something like the following, which filters on C.Data1: from A a where a.C[:b].Data1 = 0 But I'm unable to do anything with the elements of a.C[:b].D (I get various parsing exceptions) Here are the mappings, in case you're interested (nothing special, generated by ConfORM): <class name="A"> <id name="Id" type="Guid"> <generator class="guid.comb" /> </id> <map name="C"> <key column="a_key" /> <map-key-many-to-many class="B" /> <one-to-many class="C" /> </map> </class> <class name="B"> <id name="Id" type="Guid"> <generator class="guid.comb" /> </id> </class> <class name="C"> <id name="Id" type="Guid"> <generator class="guid.comb" /> </id> <property name="Data1" /> <bag name="D"> <key column="c_key" /> <one-to-many class="D" /> </bag> </class> <class name="D"> <id name="Id" type="Guid"> <generator class="guid.comb" /> </id> <property name="Data2" /> </class> Thanks!

• HttpClient multithread performance

  - by pepper

  I have an application which downloads more than 4500 html pages from 62 target hosts using HttpClient (4.1.3 or 4.2-beta). It runs on Windows 7 64-bit. Processor - Core i7 2600K. Network bandwidth - 54 Mb/s. At this moment it uses such parameters: DefaultHttpClient and PoolingClientConnectionManager; Also it hasIdleConnectionMonitorThread from http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html; Maximum total connections = 80; Default maximum connections per route = 5; For thread management it uses ForkJoinPool with the parallelism level = 5 (Do I understand correctly that it is a number of working threads?) In this case my network usage (in Windows task manager) does not rise above 2.5%. To download 4500 pages it takes 70 minutes. And in HttpClient logs I have such things: DEBUG ForkJoinPool-2-worker-1 [org.apache.http.impl.conn.PoolingClientConnectionManager]: Connection released: [id: 209][route: {}-http://stackoverflow.com][total kept alive: 6; route allocated: 1 of 5; total allocated: 10 of 80] Total allocated connections do not raise above 10-12, in spite of that I've set it up to 80 connections. If I'll try to rise parallelism level to 20 or 80, network usage remains the same but a lot connection time-outs will be generated. I've read tutorials on hc.apache.org (HttpClient Performance Optimization Guide and HttpClient Threading Guide) but they does not help. Task's code looks like this: public class ContentDownloader extends RecursiveAction { private final HttpClient httpClient; private final HttpContext context; private List<Entry> entries; public ContentDownloader(HttpClient httpClient, List<Entry> entries){ this.httpClient = httpClient; context = new BasicHttpContext(); this.entries = entries; } private void computeDirectly(Entry entry){ final HttpGet get = new HttpGet(entry.getLink()); try { HttpResponse response = httpClient.execute(get, context); int statusCode = response.getStatusLine().getStatusCode(); if ( (statusCode >= 400) && (statusCode <= 600) ) { logger.error("Couldn't get content from " + get.getURI().toString() + "\n" + response.toString()); } else { HttpEntity entity = response.getEntity(); if (entity != null) { String htmlContent = EntityUtils.toString(entity).trim(); entry.setHtml(htmlContent); EntityUtils.consumeQuietly(entity); } } } catch (Exception e) { } finally { get.releaseConnection(); } } @Override protected void compute() { if (entries.size() <= 1){ computeDirectly(entries.get(0)); return; } int split = entries.size() / 2; invokeAll(new ContentDownloader(httpClient, entries.subList(0, split)), new ContentDownloader(httpClient, entries.subList(split, entries.size()))); } } And the question is - what is the best practice to use multi threaded HttpClient, may be there is a some rules for setting up ConnectionManager and HttpClient? How can I use all of 80 connections and raise network usage? If necessary, I will provide more code.

• Migrate Spring JPA DAO unit testing to google app engine

  - by twingocerise

  I'm trying to put together a simple environment where I can get Spring, Maven, JPA, Google App Engine and DAO unit testing working happily all together. The goal is to be able to run a simple DAO unit test creating an entity and then load it again with a simple find to check it's been created properly - all of this from my maven build. My dao is making use of the JPA entity manager (query(), persist(), etc.) I've got it working no problem with hsqldb and a datasource, etc. but I'm struggling to get it working with appengine. My questions are: 1) I'm using an entity manager, injecting my persistence unit as followed. Is it OK? Is there any need for a datasource or something special? I thought not but correct me if I'm wrong. applicationContext.xml <bean id='entityManagerFactory' class='org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean'> <property name="persistenceUnitName" value="transactions-optional" /> </bean> Persistence.xml <persistence-unit name="transactions-optional"> <provider>org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider</provider> <properties> <property name="datanucleus.NontransactionalRead" value="true"/> <property name="datanucleus.NontransactionalWrite" value="true"/> <property name="datanucleus.ConnectionURL" value="appengine"/> </properties> </persistence-unit> 2) what are the dependencies I need to add to my pom file to be able to run the unit test making use of the entityManager? What about versions ? I found loads of things about appengine-api-labs/stubs/testing but none them got it working i.e. I'm getting jdo dependency missing while I'm using JPA... I also get loads of conflicts when I try to add some jars (datanucleus and stuff). So far I'm trying appengine-api-1.0-sdk v1.7.0 - ASM-all v3.3 - datanucleus core/api-jpa/enhancer v3.1.0 - datanucleus-appengine v2.0.1.1 and all the gae testing jars v1.7.0 3) Is there anything I need to add to my surefire plugin (test runner) to make sure it picks up all the dependencies? I'm getting an exhausting ClassNotFound on DatastorePersistenceProvider while it is in my classpath (I checked the jars and the mvn dependency:tree) I had a look at this but it doesn't seem to be working at all: http://www.vertigrated.com/blog/2011/02/working-maven-3-google-app-engine-plugin-with-gwt-support/ 4) Do I need to use any sot of localhelper to test my DAOs? Ideally I'd want to test my dao layer "as is" with the entity manager... what's your opinion ? Has anyone managed to run a unit test using JPA on google app engine ? 5) Do I need to set up any sort of gae.home somewhere in my pom file? Would anyone make use of it (a plugin or something) ? 6) Is the gwt-maven plugin any helpful if I don't use gwt - I'm writing a simple webservice making use of appengine, not a GWT app... Any help would be much appreciated as I've been struggling for 2 days now... Cheers, V.

• L2S DataContext out of synch: row not found or changed

  - by awrigley

  The Problem I am getting a number of errors that imply that the DataContext, or rather, the way I am using the DataContext is getting out of synch. The error occurs on db.SubmitChanges() where db is my DataContext instance. The error is: Row not found or changed. The problem only occurs intermitently, for example, adding a row then deleting it. If I stop the dev server and restart, the added row is there and I can delete it no problem. Ie, it seems that the problem is related to the DataContext losing track of the rows that have been added. IMPORTANT: Before anyone votes to close this thread, on the basis of it being a duplicate, I have checked the sql server profiler and there is no "Where 0 = 1" in the SQL. I have also recreated the dbml file, so am satisfied that the database schema is in synch with the schema represented by the dbml file. Ie, no cases of mismatched nullable/not nullable columns, etc. My Diagnosis (for what it is worth): It seems to be a problem related to how I am using the DataContext. I am new to MVC, Repositories and Services patterns, so suspect that I have wired things up wrong. The Setup Simple eLearning app in its early stages. Pupils need to be able to add and delete courses (Courses table) to their UserCourses. To do this, I have a service that gets a specific DataContext instance Dependency Injected into its constructor. Service Class Constructor: public class SqlPupilBlockService : IPupilBlockService { DataContext db; public SqlPupilBlockService(DataContext db) { this.db = db; CoursesRepository = new SqlRepository<Course>(db); UserCoursesRepository = new SqlRepository<UserCourse>(db); } // Etc, etc } The CoursesRepository and UserCoursesRepository are both private properties of the service class that are of Type IRepository (just a simple generic repository interface). Sql Respoitory Code: public class SqlRepository<T> : IRepository<T> where T : class { DataContext db; public SqlRepository(DataContext db) { this.db = db; } #region IRepository<T> Members public IQueryable<T> Query { get { return db.GetTable<T>(); } } public List<T> FetchAll() { return Query.ToList(); } public void Add(T entity) { db.GetTable<T>().InsertOnSubmit(entity); } public void Delete(T entity) { db.GetTable<T>().DeleteOnSubmit(entity); } public void Save() { db.SubmitChanges(); } #endregion } The two methods for adding and deleting UserCourses are: Service Methods for Adding and Deleting UserCourses: public void AddUserCourse(int courseId) { UserCourse uc = new UserCourse(); uc.IdCourse = courseId; uc.IdUser = UserId; uc.DateCreated = DateTime.Now; uc.DateAmended = DateTime.Now; uc.Role = "Pupil"; uc.CourseNotes = string.Empty; uc.ActiveStepIndex = 0; UserCoursesRepository.Add(uc); UserCoursesRepository.Save(); } public void DeleteUserCourse(int courseId) { var uc = (UserCoursesRepository.Query.Where(x => x.IdUser == UserId && x.IdCourse == courseId)).Single(); UserCoursesRepository.Delete(uc); UserCoursesRepository.Save(); } Ajax I am using Ajax via Ajax.BeginForm I don't think that is relevant. ASP.NET MVC 3 I am using mvc3, but don't think that is relevant: the errors are related to model code.
