  • JPA DAO integration test not throwing exception when duplicate object saved?

    - by HDave
    I am in the process of unit testing a DAO built with Spring/JPA and Hibernate as the provider. Prior to running the test, DBUnit inserted a User record with username "poweruser" -- username is the primary key in the users table. Here is the integration test method: @Test @ExpectedException(EntityExistsException.class) public void save_UserTestDataSaveUserWithPreExistingId_EntityExistsException() { User newUser = new UserImpl("poweruser"); newUser.setEmail("[email protected]"); newUser.setFirstName("New"); newUser.setLastName("User"); newUser.setPassword("secret"); dao.persist(newUser); } I have verified that the record is in the database at the start of this method. Not sure if this is relevant, but if I do a dao.flush() at the end of this method I get the following exception: javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update

  • JNDI Issues: Jboss 4.2.2 Spring 2.5 and hibernate ejb

    - by jon077
    I have a strange problem, that is causing me some grief. If the following jar is in my classpath: <dependency> <groupId>org.hibernate</groupId> <artifactId>org.hibernate.ejb</artifactId> <version>3.3.2.GA</version> </dependency> My JNDI lookup for my datasource returns null. Here is the basic code I am using to do the lookup: InitialDirContext ctx = new InitialDirContext(env); DataSource dataSource = (DataSource)ctx.lookup("java:dataContent"); Otherwise, the DataSource returns fine from the context. Unfortunately, I need the jar in order to avoid ClassCastExceptions within Jboss 4.2.2. Any help is appreciated.

  • Hibernate3: Self-Referencing Objects

    - by monojohnny
    Need some help on understanding how to do this; I'm going to be running recursive 'find' on a file system and I want to keep the information in a single DB table - with a self-referencing hierarchial structure: This is my DB Table structure I want to populate. DirObject Table: id int NOT NULL, name varchar(255) NOT NULL, parentid int NOT NULL); Here is the proposed Java Class I want to map (Fields only shown): public DirObject { int id; String name; DirObject parent; ... For the 'root' directory was going to use parentid=0; real ids will start at 1, and ideally I want hibernate to autogenerate the ids. Can somebody provide a suggested mapping file for this please; as a secondary question I thought about doing the Java Class like this instead: public DirObject { int id; String name; List<DirObject> subdirs; Could I use the same data model for either of these two methods ? (With a different mapping file of course). --- UPDATE: so I tried the mapping file suggested below (thanks!), repeated here for reference: <hibernate-mapping> <class name="my.proj.DirObject" table="category"> ... <set name="subDirs" lazy="true" inverse="true"> <key column="parentId"/> <one-to-many class="my.proj.DirObject"/> </set> <many-to-one name="parent" class="my.proj.DirObject" column="parentId" cascade="all" /> </class> ...and altered my Java class to have BOTH 'parentid' and 'getSubDirs' [returning a 'HashSet']. This appears to work - thanks, but this is the test code I used to drive this - I think I'm not doing something right here, because I thought Hibernate would take care of saving the subordinate objects in the Set without me having to do this explicitly ? DirObject dirobject=new DirObject(); dirobject.setName("/files"); dirobject.setParent(dirobject); DirObject d1, d2; d1=new DirObject(); d1.setName("subdir1"); d1.setParent(dirobject); d2=new DirObject(); d2.setName("subdir2"); d2.setParent(dirobject); HashSet<DirObject> subdirs=new HashSet<DirObject>(); subdirs.add(d1); subdirs.add(d2); dirobject.setSubdirs(subdirs); session.save(dirobject); session.save(d1); session.save(d2);

  • Modifying annotation attribute value at runtime in java

    - by Lici
    Hi folks: some methods in our model pojos have been annotated like this: @Column(name="cli_clipping_id", updatable=false, columnDefinition = "varchar(" + ModelUtils.ID_LENGTH + ") COLLATE utf8_bin") columnDefinition attribute is database vendor dependant, so when trying to drop schema in HSQLDB using Hibernate it fails: [ERROR] 16 jun 12:58:42.480 PM main [org.hibernate.tool.hbm2ddl.SchemaExport] Unexpected token: COLLATE in statement [create table cms.edi_editorial_obj (edi_uuid varchar(23) COLLATE ] To fix this, i'm thinking on this solution (but don't want to spend time if it isn't possible) , at runtime, for each method column annotated: Get @Column annotation Create a copy of the column annotation, setting columnDefinition null using javaassist. set column method annotation to the copy column annotation object overriding the old one (i don't know it this is possible) Is it possible to "hack" these methods this way? Any help would be much appreciated ...

  • How can i have different LINQ to XML quries based on two different condition?

    - by Subhen
    Hi , We want the query result should be assigned with two results based on some condition like following: var vAudioData = (from xAudioinfo in xResponse.Descendants(ns + "DIDL-Lite").Elements(ns + "item") if((xAudioinfo.Element(upnp + "artist")!=null) { select new RMSMedia { strAudioTitle = ((string)xAudioinfo.Element(dc + "title")).Trim() }; } else select new RMSMedia { strGen = ((string)xAudioinfo.Element(dc + "Gen")).Trim() }; The VarAudioData should contain both if and else condition values. I have added the if condition just to project , what is my needs, m quite sure though that we can not use if and else. Please help if there are any other approach to accomplish this. Thanks, Subhen

  • Multivalue Mysql Inserts using HibernateTemplate

    - by Langali
    I am using Spring HibernateTemplate and need to insert hundreds of records into a mysql database every second. Not sure what is the most performant way of doing it, but I am trying to see how the multi value mysql inserts do using hibernate. String query = "insert into user(age, name, birth_date) values(24, 'Joe', '2010-05-19 14:33:14'), (25, 'Joe1', '2010-05-19 14:33:14')" getHibernateTemplate().execute(new HibernateCallback(){ public Object doInHibernate(Session session) throws HibernateException, SQLException { return session.createSQLQuery(query).executeUpdate(); } }); But I get this error: 'could not execute native bulk manipulation query.' Please check your query ..... Any idea of I can use a multi value mysql insert using Hibernate? or is my query incorrect? Any other ways that I can improve the performance? I did try the saveOrUpdateAll() method, and that wasn't good enough!

  • Is there a better way to deal with reserved characters when parsing XML/JSON data on the iPhone?

    - by Charles S.
    The following code works, but it's ugly and creates a bunch of autoreleased objects. I'm using similar code for parsing reserved HTML characters as well (for quotes, & symbols, etc). I'm just wondering... Is there a cleaner way? NSString *result = [[NSString alloc] initWithString:userInput]; NSString *result2 = [result stringByReplacingOccurrencesOfString:@"#" withString:@"\%23"]; NSString *result3 = [result2 stringByReplacingOccurrencesOfString:@" " withString:@"\%20"]; formatted = [[result3 stringByReplacingOccurrencesOfString:@"&" withString:@"\%26"] retain]; [result release];

  • Two collections manyToOne to same primary key

    - by Ethiel
    Hi, guys, I'm coding a web page in Hibernate-JPA and Oracle. I need the following: I have two classes: Place and Home. I need two collections of type Place in every Home: I do the following: Home: @ManyToOne @JoinColumn(name="ID_PLACES") private List<Places>places1; @ManyToOne @JoinColumn(name="ID_PLACES") private List<Places>Places2; However, hibernate got an exception (repeated column) and forces to me to mapping with insert and update to false. How Can I get Two ManyToOne relationship to same primary key with insert a true?.

  • What is the difference between these 2 XML LINQ Queries?

    - by Jon
    I have the 2 following LINQ queries and I haven't quite got my head around LINQ so what is the difference between the 2 approaches below? Is there a circumstance where one approach is better than another? ChequeDocument.Descendants("ERRORS").Where(x=>(string)x.Attribute("D") == "").Count(); (from x in ChequeDocument.Descendants("ERRORS") where (string)x.Attribute("D") == "" select x).Count())

  • C# + Querying XML with LINQ

    - by user336786
    Hello, I'm learning to use LINQ. I have seen some videos online that have really impressed me. In an effort to learn LINQ myself, I decided to try to write a query to the NOAA web service. If you put "http://www.weather.gov/forecasts/xml/sample_products/browser_interface/ndfdBrowserClientByDay.php?zipCodeList=20001&format=24+hourly&startDate=2010-06-10&numDays=5" in your browser's address bar, you will see some XML. I have successfully retrieved that XML in a C# program. I am loading the XML into a LINQable entity by doing the following: string xml = QueryWeatherService(); XDocument weather = XDocument.Parse(xml); I have a class called DailyForecast defined as follows: public class DailyForecast { public float HighTemperature { get; set; } public float LowTemperature { get; set; } public float PrecipitationPossibility { get; set; } public string WeatherSummary { get; set; } } I'm trying write a LINQ query that adheres to the structure of my DailyForecast class. At this time, I've only gotten to this far: var results = from day in response.Descendants("parameters") select day; Not very far I know. Because of the structure of the XML returned, I'm not sure it is possible to solely use a LINQ query. I think the only way to do this is via a loop and traverse the XML. I'm seeking someone to correct me if I'm wrong. Can someone please tell me if I can get results using purely LINQ that adhere to the structure of the DailyForecast class? If so, how? Thank you!

  • Using Java classes(whole module with Spring/Hibernate dependency) in Grails

    - by Sitaram
    I have a Java/Spring/Hibernate application with a payment module. Payment module has some domain classes for payment subscription and transactions etc. Corresponding hibernate mapping files are there. This module uses applicationContext.xml for some of the configuration it needs. Also, This module has a PaymentService which uses a paymentDAO to do all database related work. Now, I want to use this module as it is(without any or minimal re-writing) in my other application(Grails application). I want to bring in the payment module as a jar or copy the source files to src/java folder in Grails. With that background, I have following queries: Will the existing applicationContext.xml for Spring configuration in the module will work as it is in Grails? Does it merge with rest of Grails's Spring config? Where do I put the applicationContext.xml? classpath? src/java should work? Can I bundle the applicationContext.xml in Jar(If I use jar option) and can overwrite in Grails if anything needs to be changed? Multiple bean definition problems in that case? PaymentService recognized as regular service? Will it be auto-injected in controllers and/or other services? Will PaymentDAO use the datasource configuration of Grails? Where do I put the hbm files of this module? Can I bundle the hbm files in Jar(If I use jar option) and can overwrite in Grails if anything needs to be changed? Which hbms are picked? or, there will be problems with that? Too many questions! :) All these concerns are actually before trying. I am going to try this in next few days(busy currently). Any help is appreciated. Thanks. Sitaram Meena

  • Prevent <xsi:nil="true"> on Nullable Value Types when Serializing to XML.

    - by Nat Ryall
    I have added some nullable value types to my serializable class. I perform a serialization using XmlSerializer but when the value is set to null, I get an empty node with xsi:nil="true". This is the correct behaviour as I have found here: http://msdn.microsoft.com/en-us/library/ybce7f69%28VS.80%29.aspx Is there a way to switch off this option so that nothing is output when the value type is null?

  • HQL: illegal attempt to dereference collection

    - by skip
    The situation is like this: I have an entity Book that holds a one-to-many relationship with Chapter. Now if I try the query, "from Book book inner join book.chapters chapter where chapter.title like '%hibernate%'", it gives me the desired result. But if I try, "from Book where book.chapters.title like '%hibernate%'", I get the error illegal attempt to dereference collection. The thing is that I only want the collection of Book objects in return and not a collection of pair of Book and Chapter objects in return which I get with the former query. Could someone help me understand?

  • How to reference a string from another package in a library using XML in Android?

    - by Garret Wilson
    The Android documentation tells me that I can access a string from another package by using the "package name", whatever that means: @[<package_name>:]<resource_type>/<resource_name> So in my manifest I want to access a string that I've placed in a separate library project, in the com.globalmentor.android package---that's where my R class is, after all: <activity android:label="@com.globalmentor.android:string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> That doesn't even compile. But this does: <activity android:label="@string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> Why? What does the Android documentation mean which it talks about the "package_name"? Why doesn't the first example work, and why does the second example work? I don't want all my resource names merged into the same R file---I want them partitioned into packages, like I wrote them.

  • How easy would it be to refactor a small JSP/Servlet/JDBC project to SpringMVC/Hibernate

    - by John
    With reference to this post, I am considering starting a new web-based Java project. Since I don't know Spring/Hibernate I was concerned if it's a bad plan to start learning them while creating a new project, especially since it will slow down the early development. One idea I had was to write a prototype using tech I do know, namely JSP/Servlets/JDBC, since I can get this running much quicker with my current knowledge. I could then throw the whole thing away and start over with Spring, etc, but I'd like to consider how easy it would be to refactor a smallish project from JSP/Servlets/JDB to SpringMVC/Hibernate? My DB could of course be re-used but what about other code... would I expect to save most of it plugged into an MVC framework, or is the paradigm shift big enough this would cause more trouble than it avoids? Please use the other question for more general advice on choosing technologies
