Не удается сохранить запись с помощью Persistent InputStream в OpenJPA

Question

Я пытаюсь сохранить запись с отображенным полем @Persistent InputStream. Контекст: JDK 1.8, LiferayPortal на Tomee 1.7.1 (OpenJPA 2.4-patch). Извините за стек, загрязненный Liferay.

@Entity 
@Table(name = "file_entries") 
public class FileEntry implements Serializable { 
    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private Long id; 

    @Column(length = 120) 
    private String createdBy; 

    @Temporal(TemporalType.TIMESTAMP) 
    private Date created; 

    @Column(length = 120) 
    private String modifiedBy; 

    @Temporal(TemporalType.TIMESTAMP) 
    private Date modified; 

    @Column(length = 200) 
    private String title; 

    @Column(length = 2000) 
    private String description; 

    @Column(length = 240) 
    private String filename; 

    @Column(length = 60) 
    private String extension; 

    @Column(length = 20) 
    private String version; 

    @Column(length = 240) 
    private String contentType; 

    @Persistent(fetch = FetchType.LAZY) 
    private InputStream content; 

    public Long getId() { 
     return id; 
    } 

    public void setId(Long id) { 
     this.id = id; 
    } 

    public String getCreatedBy() { 
     return createdBy; 
    } 

    public void setCreatedBy(String createdBy) { 
     this.createdBy = createdBy; 
    } 

    public Date getCreated() { 
     return created; 
    } 

    public void setCreated(Date created) { 
     this.created = created; 
    } 

    public String getModifiedBy() { 
     return modifiedBy; 
    } 

    public void setModifiedBy(String modifiedBy) { 
     this.modifiedBy = modifiedBy; 
    } 

    public Date getModified() { 
     return modified; 
    } 

    public void setModified(Date modified) { 
     this.modified = modified; 
    } 

    public String getTitle() { 
     return title; 
    } 

    public void setTitle(String title) { 
     this.title = title; 
    } 

    public String getDescription() { 
     return description; 
    } 

    public void setDescription(String description) { 
     this.description = description; 
    } 

    public String getFilename() { 
     return filename; 
    } 

    public void setFilename(String filename) { 
     this.filename = filename; 
    } 

    public String getExtension() { 
     return extension; 
    } 

    public void setExtension(String extension) { 
     this.extension = extension; 
    } 

    public String getVersion() { 
     return version; 
    } 

    public void setVersion(String version) { 
     this.version = version; 
    } 

    public InputStream getContent() { 
     return content; 
    } 

    public void setContent(InputStream content) { 
     this.content = content; 
    } 

    public String getContentType() { 
     return contentType; 
    } 

    public void setContentType(String contentType) { 
     this.contentType = contentType; 
    } 
} 

И когда сохраняющиеся:

logo = new FileEntry(); 
logo.setContent(new FileInputStream("some_local_file")); 
entityService.persist(logo); 

Я получаю следующее исключение.

Декларация единицы сохранения:

<persistence-unit name="uefiscdi" transaction-type="JTA"> 
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> 
    <jta-data-source>uefiscdiDS</jta-data-source> 
    <properties> 
     <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)" /> 
     <property name="openjpa.jdbc.DBDictionary" value="postgres" /> 
     <property name="openjpa.Log" value="DefaultLevel=INFO, Tool=INFO" /> 
    </properties> 
</persistence-unit> 

Декларация Datasource является:

<Resource id="uefiscdiDS" type="DataSource"> 
    JdbcDriver   org.postgresql.Driver 
    JdbcUrl    jdbc:postgresql://localhost:5432/db_name 
    UserName   user_name 
    Password   user_password 
    JtaManaged   true 
    DefaultAutoCommit false 
</Resource> 

Я попытался с DefaultAutoCommit истина/ложь/не объявлена ​​... тем же исключением.

Answer 1

Просто выстрел в темноте, но вы попробовали позвонить em.persist(...), а не em.merge(..)?

Если это не сработает, может быть полезно, если вы где-нибудь разместите полную трассировку стека. Боюсь, вы, возможно, отрезали важные части.
