  • passing custom object as parameter to a webmethod of asp.net web service

    - by Jon
    Hi, I have a custom class declared as follows (in vb.net) <Serializable()> _ Public Class NumInfo Public n As String Public f As Integer Public fc As char() Public t As Integer Public tc As char() Private validFlag As Boolean = True Public Sub New() End Sub 'I also have public properties(read/write) for all the public variablesEnd Class In my service.asmx codebehind class I have a webmethod as follows: <WebMethod()> _ <XmlInclude(GetType(NumInfo))> _ Public Function ConvertTo(ByVal info As NumInfo) As String Return mbc(info)'mbc is another function defined in my service.asmx "service" class End Function The problem is that when I start debugging it to test it, the page that I get does not contain any fields where I could input the values for the public fields of numInfo. How do I initialise the class? There is no "Invoke" button either. All I see are soap details as below: ConvertToTestThe test form is only available for methods with primitive types as parameters.SOAP 1.1The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.POST /Converter/BC.asmx HTTP/1.1Host: localhostContent-Type: text/xml; charset=utf-8Content-Length: lengthSOAPAction: "http://Services/ConvertTo"<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <ConvertTo xmlns="http://Services/"> <info> <n>string</n> <f>int&lt/f> <fc> <char>char</char> <char>char>/char> </fc>..etc.. What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button. I just can't seem to get it working with custom object. Help!

  • Spring transactions not committing

    - by Clinton Bosch
    I am struggling to get my spring managed transactions to commit, could someone please spot what I have done wrong. All my tables are mysql InnonDB tables. My RemoteServiceServlet (GWT) is as follows: public class TrainTrackServiceImpl extends RemoteServiceServlet implements TrainTrackService { @Autowired private DAO dao; @Override public void init(ServletConfig config) throws ServletException { super.init(config); WebApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(config.getServletContext()); AutowireCapableBeanFactory beanFactory = ctx.getAutowireCapableBeanFactory(); beanFactory.autowireBean(this); } @Transactional(propagation= Propagation.REQUIRED, rollbackFor=Exception.class) public UserDTO createUser(String firstName, String lastName, String idNumber, String cellPhone, String email, int merchantId) { User user = new User(); user.setFirstName(firstName); user.setLastName(lastName); user.setIdNumber(idNumber); user.setCellphone(cellPhone); user.setEmail(email); user.setDateCreated(new Date()); Merchant merchant = (Merchant) dao.find(Merchant.class, merchantId); if (merchant != null) { user.setMerchant(merchant); } // Save the user. dao.saveOrUpdate(user); UserDTO dto = new UserDTO(); dto.id = user.getId(); dto.firstName = user.getFirstName(); dto.lastName = user.getLastName(); return dto; } The DAO is as follows: public class DAO extends HibernateDaoSupport { private String adminUsername; private String adminPassword; private String godUsername; private String godPassword; public String getAdminUsername() { return adminUsername; } public void setAdminUsername(String adminUsername) { this.adminUsername = adminUsername; } public String getAdminPassword() { return adminPassword; } public void setAdminPassword(String adminPassword) { this.adminPassword = adminPassword; } public String getGodUsername() { return godUsername; } public void setGodUsername(String godUsername) { this.godUsername = godUsername; } public String getGodPassword() { return godPassword; } public void setGodPassword(String godPassword) { this.godPassword = godPassword; } public void saveOrUpdate(ModelObject obj) { getHibernateTemplate().saveOrUpdate(obj); } And my applicationContext.xml is as follows: <context:annotation-config/> <context:component-scan base-package="za.co.xxx.traintrack.server"/> <!-- Application properties --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>file:${user.dir}/@propertiesFile@</value> </list> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${connection.dialect}</prop> <prop key="hibernate.connection.username">${connection.username}</prop> <prop key="hibernate.connection.password">${connection.password}</prop> <prop key="hibernate.connection.url">${connection.url}</prop> <prop key="hibernate.connection.driver_class">${connection.driver.class}</prop> <prop key="hibernate.show_sql">${show.sql}</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.c3p0.min_size">5</prop> <prop key="hibernate.c3p0.max_size">20</prop> <prop key="hibernate.c3p0.timeout">300</prop> <prop key="hibernate.c3p0.max_statements">50</prop> <prop key="hibernate.c3p0.idle_test_period">60</prop> </props> </property> <property name="annotatedClasses"> <list> <value>za.co.xxx.traintrack.server.model.Answer</value> <value>za.co.xxx.traintrack.server.model.Company</value> <value>za.co.xxx.traintrack.server.model.CompanyRegion</value> <value>za.co.xxx.traintrack.server.model.Merchant</value> <value>za.co.xxx.traintrack.server.model.Module</value> <value>za.co.xxx.traintrack.server.model.Question</value> <value>za.co.xxx.traintrack.server.model.User</value> <value>za.co.xxx.traintrack.server.model.CompletedModule</value> </list> </property> </bean> <bean id="dao" class="za.co.xxx.traintrack.server.DAO"> <property name="sessionFactory" ref="sessionFactory"/> <property name="adminUsername" value="${admin.user.name}"/> <property name="adminPassword" value="${admin.user.password}"/> <property name="godUsername" value="${god.user.name}"/> <property name="godPassword" value="${god.user.password}"/> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory"> <ref local="sessionFactory"/> </property> </bean> <!-- enable the configuration of transactional behavior based on annotations --> <tx:annotation-driven transaction-manager="transactionManager"/> If I change the sessionFactory property to be autoCommit=true then my object does get persisited. <prop key="hibernate.connection.autocommit">true</prop>

  • UML Modelling in C++Builder 2010 Professional

    - by Gordon Brandly
    I'd like to do some basic class diagram UML models in the Pro version of C++Builder 2010. Embarcadero has a C++Builder Features Matrix document, one line of which says "UML Code Visualization – at any time, get a UML model view of your source code" and has a check in the "Professional" column of that table -- I assume this means it should be available to me. Yet, when I open an existing project and do a View | Model View, there's nothing in the Model View window. The only diagram I can find is on the Graph tab of the C++ Class Explorer. I wouldn't call that a UML diagram myself -- is that what Embarcadero is referring to? Embarcadero's table shows that many UML diagrams are not available in Pro, but it looks to me like Class Diagrams should be available. Other lines in that same table indicate that both "Full two-way class diagrams with synchronization between code and diagrams" and "Diagram hyper-linking and annotations" are also supposed to be available in Pro. The Class Explorer graph is one-way only as far as I can tell, so I hope they're referring to something else I haven't been able to find so far. Thanks for any insight into this.

  • JNI - GetObjectField returns NULL

    - by Daniel
    I'm currently working on Mangler's Android implementation. I have a java class that looks like so: public class VentriloEventData { public short type; public class _pcm { public int length; public short send_type; public int rate; public byte channels; }; _pcm pcm; } The signature for my pcm object: $ javap -s -p VentriloEventData ... org.mangler.VentriloEventData$_pcm pcm; Signature: Lorg/mangler/VentriloEventData$_pcm; I am implementing a native JNI function called getevent, which will write to the fields in an instance of the VentriloEventData class. For what it's worth, it's defined and called in Java like so: public static native int getevent(VentriloEventData data); VentriloEventData data = new VentriloEventData(); getevent(data); And my JNI implementation of getevent: JNIEXPORT jint JNICALL Java_org_mangler_VentriloInterface_getevent(JNIEnv* env, jobject obj, jobject eventdata) { v3_event *ev = v3_get_event(V3_BLOCK); if(ev != NULL) { jclass event_class = (*env)->GetObjectClass(env, eventdata); // Event type. jfieldID type_field = (*env)->GetFieldID(env, event_class, "type", "S"); (*env)->SetShortField( env, eventdata, type_field, 1234 ); // Get PCM class. jfieldID pcm_field = (*env)->GetFieldID(env, event_class, "pcm", "Lorg/mangler/VentriloEventData$_pcm;"); jobject pcm = (*env)->GetObjectField( env, eventdata, pcm_field ); jclass pcm_class = (*env)->GetObjectClass(env, pcm); // Set PCM fields. jfieldID pcm_length_field = (*env)->GetFieldID(env, pcm_class, "length", "I"); (*env)->SetIntField( env, pcm, pcm_length_field, 1337 ); free(ev); } return 0; } The code above works fine for writing into the type field (that is not wrapped by the _pcm class). Once getevent is called, data.type is verified to be 1234 at the java side :) My problem is that the assertion "pcm != NULL" will fail. Note that pcm_field != NULL, which probably indicates that the signature to that field is correct... so there must be something wrong with my call to GetObjectField. It looks fine though if I compare it to the official JNI docs. Been bashing my head on this problem for the past 2 hours and I'm getting a little desperate.. hoping a different perspective will help me out on this one.

  • REST web service keeps first POST parametrs

    - by Diego
    I have a web service in REST, designed with Java and deployed on Tomcat. This is the web service structure: @Path("Personas") public class Personas { @Context private UriInfo context; /** * Creates a new instance of ServiceResource */ public Personas() { } @GET @Produces("text/html") public String consultarEdad (@QueryParam("nombre") String nombre) { ConectorCliente c = new ConectorCliente("root", "cafe.sql", "test"); int edad = c.consultarEdad(nombre); if (edad == Integer.MIN_VALUE) return "-1"; return String.valueOf(edad); } @POST @Produces("text/html") public String insertarPersona(@QueryParam("nombre") String msg, @QueryParam("edad") int edad) { ConectorCliente c = new ConectorCliente("usr", "passwd", "dbname"); c.agregar(msg, edad); return "listo"; } } Where ConectorCliente class is MySQL connector and querying class. So, I had tested this with the @GET actually doing POST work, any user inputed data and information from ma Java FX app and it went direct to webservice's database. However, I changed so the CREATE operation was performed through a webservice responding to an actual POST HTTP request. However, when I run the client and add some info, parameters go OK, but in next time I input different parameters it'll input the same. I run this several times and I can't get the reason of it. This is the clients code: public class WebServicePersonasConsumer { private WebTarget webTarget; private Client client; private static final String BASE_URI = "http://localhost:8080/GetSomeRest/serviciosweb/"; public WebServicePersonasConsumer() { client = javax.ws.rs.client.ClientBuilder.newClient(); webTarget = client.target(BASE_URI).path("Personas"); } public <T> T insertarPersona(Class<T> responseType, String nombre, String edad) throws ClientErrorException { String[] queryParamNames = new String[]{"nombre", "edad"}; String[] queryParamValues = new String[]{nombre, edad}; ; javax.ws.rs.core.Form form = getQueryOrFormParams(queryParamNames, queryParamValues); javax.ws.rs.core.MultivaluedMap<String, String> map = form.asMap(); for (java.util.Map.Entry<String, java.util.List<String>> entry : map.entrySet()) { java.util.List<String> list = entry.getValue(); String[] values = list.toArray(new String[list.size()]); webTarget = webTarget.queryParam(entry.getKey(), (Object[]) values); } return webTarget.request().post(null, responseType); } public <T> T consultarEdad(Class<T> responseType, String nombre) throws ClientErrorException { String[] queryParamNames = new String[]{"nombre"}; String[] queryParamValues = new String[]{nombre}; ; javax.ws.rs.core.Form form = getQueryOrFormParams(queryParamNames, queryParamValues); javax.ws.rs.core.MultivaluedMap<String, String> map = form.asMap(); for (java.util.Map.Entry<String, java.util.List<String>> entry : map.entrySet()) { java.util.List<String> list = entry.getValue(); String[] values = list.toArray(new String[list.size()]); webTarget = webTarget.queryParam(entry.getKey(), (Object[]) values); } return webTarget.request(javax.ws.rs.core.MediaType.TEXT_HTML).get(responseType); } private Form getQueryOrFormParams(String[] paramNames, String[] paramValues) { Form form = new javax.ws.rs.core.Form(); for (int i = 0; i < paramNames.length; i++) { if (paramValues[i] != null) { form = form.param(paramNames[i], paramValues[i]); } } return form; } public void close() { client.close(); } } And this this the code when I perform the operations in a Java FX app: String nombre = nombreTextField.getText(); String edad = edadTextField.getText(); String insertToDatabase = consumidor.insertarPersona(String.class, nombre, edad); So, as parameters are taken from TextFields, is quite odd why second, third, fourth and so on POSTS post the SAME.

  • Recommendations for a C++ polymorphic, seekable, binary I/O interface

    - by Trevor Robinson
    I've been using std::istream and ostream as a polymorphic interface for random-access binary I/O in C++, but it seems suboptimal in numerous ways: 64-bit seeks are non-portable and error-prone due to streampos/streamoff limitations; currently using boost/iostreams/positioning.hpp as a workaround, but it requires vigilance Missing operations such as truncating or extending a file (ala POSIX ftruncate) Inconsistency between concrete implementations; e.g. stringstream has independent get/put positions whereas filestream does not Inconsistency between platform implementations; e.g. behavior of seeking pass the end of a file or usage of failbit/badbit on errors Don't need all the formatting facilities of stream or possibly even the buffering of streambuf streambuf error reporting (i.e. exceptions vs. returning an error indicator) is supposedly implementation-dependent in practice I like the simplified interface provided by the Boost.Iostreams Device concept, but it's provided as function templates rather than a polymorphic class. (There is a device class, but it's not polymorphic and is just an implementation helper class not necessarily used by the supplied device implementations.) I'm primarily using large disk files, but I really want polymorphism so I can easily substitute alternate implementations (e.g. use stringstream instead of fstream for unit tests) without all the complexity and compile-time coupling of deep template instantiation. Does anyone have any recommendations of a standard approach to this? It seems like a common situation, so I don't want to invent my own interfaces unnecessarily. As an example, something like java.nio.FileChannel seems ideal. My best solution so far is to put a thin polymorphic layer on top of Boost.Iostreams devices. For example: class my_istream { public: virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) = 0; virtual std::streamsize read(char* s, std::streamsize n) = 0; virtual void close() = 0; }; template <class T> class boost_istream : public my_istream { public: boost_istream(const T& device) : m_device(device) { } virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) { return boost::iostreams::seek(m_device, off, way); } virtual std::streamsize read(char* s, std::streamsize n) { return boost::iostreams::read(m_device, s, n); } virtual void close() { boost::iostreams::close(m_device); } private: T m_device; };

  • Multiple CSS Classes: Properties Overlapping based on the order defined.

    - by Jian Lin
    Is there a rule in CSS that determines the cascading order when multiple classes are defined on an element? (class="one two" vs class="two one") Right now, there seems to be no such effect. Example: both divs are orange in color on Firefox <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <style> .one { border: 6px dashed green } .two { border: 6px dashed orange } </style> </head> <body> <div class="one two"> hello world </div> <div class="two one"> hello world </div>

  • Code Analysis Error: Declare types in namespaces

    - by George
    Is VS2010, I analyzed my code and got this error: Warning 64 CA1050 : Microsoft.Design : 'ApplicationVariables' should be declared inside a namespace. C:\My\Code\BESI\BESI\App_Code\ApplicationVariables.vb 10 C:\...\BESI\ Here is some reference info on the error. Essentially, I tried to create a class to be used to access data in the Application object in a typed way. The warning message said unless I put my (ApplicationVariables) class in a Namespace, that I wouldn't be able to use it. But I am using it, so what gives? Also, here is a link to another StackOverflow article that talks about how to disable this warning in VS2008, but how would you disable it for 2010? There is no GlobalSuppressions.vb file for VS2010. Here is the code it is complaining a bout: Public Class ApplicationVariables 'Shared Sub New() 'End Sub 'New Public Shared Property PaymentMethods() As PaymentMethods Get Return CType(HttpContext.Current.Application.Item("PaymentMethods"), PaymentMethods) End Get Set(ByVal value As PaymentMethods) HttpContext.Current.Application.Item("PaymentMethods") = value End Set End Property 'Etc, Etc...

Class A: @interface ClassA - (NSString*)foo; @end Class A category @interface ClassA (Properties) - (void)someCategoryMethod; @property (nonatomic, readonly) NSString *foo; @end Now when I do this, it seems to work, but it gives me warnings because I am not synthesizing the property in my category implementation. How do I tell the compiler everything is actually just fine since the original class synthesizes the property for me?

  • Eager loading OneToMany in Hibernate with JPA2

    - by pihentagy
    I have a simple @OneToMany between Person and Pet entities: @OneToMany(mappedBy="owner", cascade=CascadeType.ALL, fetch=FetchType.EAGER) public Set<Pet> getPets() { return pets; } I would like to load all Persons with associated Pets. So I came up with this (inside a test class): @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration public class AppTest { @Test @Rollback(false) @Transactional(readOnly = false) public void testApp() { CriteriaBuilder qb = em.getCriteriaBuilder(); CriteriaQuery<Person> c = qb.createQuery(Person.class); Root<Person> p1 = c.from(Person.class); SetJoin<Person, Pet> join = p1.join(Person_.pets); TypedQuery<Person> q = em.createQuery(c); List<Person> persons = q.getResultList(); for (Person p : persons) { System.out.println(p.getName()); for (Pet pet : p.getPets()) { System.out.println("\t" + pet.getNick()); } } However, turning the SQL logging on shows, that it executes 3 queries (having 2 Persons in the DB). Hibernate: select person0_.id as id0_, person0_.name as name0_, person0_.sex as sex0_ from Person person0_ inner join Pet pets1_ on person0_.id=pets1_.owner_id Hibernate: select pets0_.owner_id as owner3_0_1_, pets0_.id as id1_, pets0_.id as id1_0_, pets0_.nick as nick1_0_, pets0_.owner_id as owner3_1_0_ from Pet pets0_ where pets0_.owner_id=? Hibernate: select pets0_.owner_id as owner3_0_1_, pets0_.id as id1_, pets0_.id as id1_0_, pets0_.nick as nick1_0_, pets0_.owner_id as owner3_1_0_ from Pet pets0_ where pets0_.owner_id=? Any tips? Thanks Gergo

  • How do I model teams and gameplay in this scorekeeping application?

    - by Eric Hill
    I'm writing a scorekeeping application for card game that has a few possibly-interesting constraints. The application accepts user registrations for players, then lets them check-in to a particular game (modeled as Event). After the final player registers, the app should generate teams, singles or doubles, depending on the preference of the person running the game and some validations (can't do doubles if there's an odd number checked in). There are @event.teams.count rounds in the game. To sum up: An event consists of `@event.teams.count` rounds; Teams can have 1 or more players Events have n or n/2 teams (depending on whether it's singles or doubles) Users will be members of different teams at different events Currently I have a rat's nest of associations: class User < ActiveRecord::Base has_many :teams, :through => :players has_many :events, :through => :teams class Event < ActiveRecord::Base has_many :rounds has_many :teams has_many :players, :through => :teams class Player < ActiveRecord::Base belongs_to :user belongs_to :team end class Team < ActiveRecord::Base has_many :players belongs_to :event end class Round < ActiveRecord::Base belongs_to :event belongs_to :user end The sticky part is team generation. I have basically a "start game" button that should freeze the registrations and pair up teams either singly or doubly, and render to Round#new so that the first (and subsequent) matches can be scored. Currently I'm implementing this as a check on Round#new that calls Event#generate_teams and displays the view: # Event#generate_teams def generate_teams # User has_many :events, :through => :registrations # self.doubles is a boolean denoting 2 players per team registrations.in_groups_of(self.doubles ? 2 : 1, nil).each do |side| self.teams << Player.create(self,side) end end Which doesn't work. Should there maybe be a Game model that ties everything together rather than (my current method) defining the game as an abstraction via the relationships between Events, Users, and Rounds (and Teams and Players and etc.)? My head is swimming.

  • a java applet question

    - by Robert
    Hello there. I have a question on the java applet.I've created a java applet,which is a board game,that can have a 2*2 array with row number and column number both set to 9 by default. Now I want to extend my applet a bit,that the user can specify the size they want on the command-line,then the applet class will create an applet with correspoding size. I try to add a constructor in the applet class,but the Eclipse complains,I also tried another class,which will create an instance of this applet with size as an instance variable,but it is not working. Could anyone help me a little bit on where to put a main() method that can take care of user-specified board sized,then create an array in my applet class accordingly? Thanks a lot. Rob

  • Extension methods for encapsulation and reusability

    - by tzaman
    In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself?

  • Send keystrokes to TextBox

    - by tanascius
    I have a derived TextBox where I intercept the userinput to manipulate it. However I have to preserve the original typed input. So my idea was to hold an inner TextBox within my derived class and send the user's input to that TextBox before manipulating it. The reason for this approach is that I do not want to take care of all this special actions like: typing something, ctrl+a, [del], type something else, [backspace] and so on ... However I do not know how to send a single keystroke (keycode, ascii, char) to a TextBox. Maybe you have another idea without an inner TextBox at all? Thank you!

  • New to programming

    - by Shaun
    I have a form (Quote) with an auto-number ID, on the form at the moment are two subforms that show different items (sub 1 shows partition modules sub 2 shows partition abutments) both forms use the same parts tables to build them. Both forms are linked to the quote form using the ID. All works well until the forms is refreshed or re-loaded, subform 1 shows the module names and quantities and blank spaces for the abutment names but shows the quantiews for the abutments, the reverse of this is shown in the abutments subform 2. When the lists for the variuos types and the detailed parts lists are printed they are correct. This seems to be only a visual problem. All based on Access 2003. Subform 1 SELECT Quote_Modules.ModuleID, Quote_Modules.QuoteID, Quote_Modules.ModuleDescription, Quote_Modules.ModuleQty, Quote.Style, Quote.Trim FROM Quote INNER JOIN Quote_Modules ON Quote.QuoteID=Quote_Modules.QuoteID ORDER BY Quote_Modules.ModuleID; Subform 2 SELECT Quote_Modules.ModuleID, Quote_Modules.QuoteID, Quote_Modules.ModuleDescription, Quote_Modules.ModuleQty, Quote.Style, Quote.Trim FROM Quote INNER JOIN Quote_Modules ON Quote.QuoteID=Quote_Modules.QuoteID ORDER BY Quote_Modules.ModuleID;

  • no Jquery only Javascrip fadein function with cleartype fot text

  • Customizing error handling of JAXB unmarshall process

    - by ekeren
    Assuming I have a schema that describes a root element class Root that contains a List<Entry> where the Entry class has a required field name. Here is how it looks in code: @XmlRootElement class Root{ @XmlElement(name="entry") public List<Entry> entries = Lists.newArrayList(); } @XmlRootElement class Entry{ @XmlElement(name="name",required=true) public String name; } If I supply the following XML for unmarshalling: <root> <entry> <name>ekeren</name> </entry> <entry> </entry> </root> I have a problem because the second entry does not contain a name. So unmarshall produces null. Is there a way to customize JAXB to unmarshall a Root object that will only contain the "good" entry?
