问题 Having a trivial code like this: @XmlRootElement @XmlAccessorType(XmlAccessType.FIELD) class A { @XmlPath("B/text()") private String b; @XmlPath("C/text()") private Integer c; ... } It works absolutely fine as long as I have apt values in my XML. I'd like to mark the field c as required, so MOXy throw every time I try to read the document where c is either not set, or invalid. What's the easiest solution? Update: Setting default values will also do. 回答1: EclipseLink JAXB (MOXy) or any JAXB

问题 I generated a maven project with the quickstart archetype. So I obtained the following project structure: |-- src | |-- main | | |-- java | | |-- resources | |-- test | | |-- java | | |-- resources |-- pom.xml I modified the "pom.xml" file : <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com

问题 Is it possible to change the generated DDL statements of EclipseLink during the creation process? In the persistence.xml I use the table-creation-suffix, but it adds only some things to the CREATE TABLE statements. There are also a lot of ALTER TABLE statements, which I can not change. Something like a table-alteration-suffix would be nice. <property name="eclipselink.ddl-generation.table-creation-suffix" value=";" /> <property name="eclipselink.ddl-generation" value="drop-and-create-tables"

问题 I try to make a simple app using a rest service, eclipseLink and mysql. I want to make this run on a TomEE server (apache-tomee-plume-1.7.4). I deploy the app with eclipse. The deployment seems to be ok When I go to http://localhost:8080/eleve/ I'm getting : javax.servlet.ServletException: Error processing webservice request org.apache.tomee.webservices.CXFJAXRSFilter.doFilter(CXFJAXRSFilter.java:98) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) java.io.IOException:

问题 I am using the latest version of EclipseLink (2.2.0) with SQL Server 2005. Generating the classes, the type NVARCHAR is mapped to type Object in the classes. I suppose it should map to type String. Why is this happening? 回答1: How are you generating the classes? Are you using Eclipse Dali? I would just change the generate code to String. Perhaps report a bug with the IDE you are using. EclipseLink itself, does not generate classes. 来源： https://stackoverflow.com/questions/5883670/why

问题 I'm using EclipseLink as JPA provider in a Java SE project. I have properly configured the weaving to allow the Lazy Loading. Unlike Hibernate (which throws LazyInitializationException), EclipseLink can get a proxy of LAZY relationship, even with a closed EntityManager. To run this query, it gets a new connection from the pool. Is there some setting that disables or changes the behavior of this feature? I need to get a null value or an exception when trying to access an unloaded attribute,

问题 I am testing MOXy 2.5.0 RC1. I marshalled the following to a string: <c r="C3" xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main"> <v>20</v> </c> It is represented by https://github.com/plutext/docx4j/blob/master/src/xlsx4j/java/org/xlsx4j/sml/Cell.java Notice the absence of any @XmlRootElement annotation With the reference implementation, the result, as expected, is: javax.xml.bind.MarshalException - with linked exception: [com.sun.istack.internal.SAXException2: unable to

问题 I have two entities defined as: @Entity public class FileMaster implements java.io.Serializable{ @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long fileId; @NotNull @Column(unique = true) private String fileNumber = ""; private String subject = ""; @Temporal(TemporalType.DATE) private Date date=null; private String authPerson=""; private String authDesign=""; private String department=""; @OneToMany(mappedBy = "fileMaster", cascade = CascadeType.ALL, orphanRemoval = true)

问题 This is about using JAX-WS with EclipseLink MOXy and my problem of not being able to use MOXy's external mapping documents in this combination. (The same actually seems to apply to JAX-RS as well, but I'm limiting the details to JAX-WS to keep this from becoming even longer than it already is). I first describe (in some detail) the context of my requirements and the test code I've written to try and solve them. The actual question follows at the end of the post. The context: In some legacy
