    <p>here's the problem. I'm using Spring 3.0.4 to create a rest web service (and actually I am a novice). I want to persist an object via hibernate passed by the client as an XML representation. To accomplish this task I use jaxb2.</p> <p>The object the client send is a node having two sons objects, namely data and metadata.</p> <p>the problem is that when the client sends its XML the SIUserData is unmarshalled in an umpredictable byte[] array: sometimes a part of the imput is cut away and sometimes it is simply empty.</p> <p>for example this input</p> <pre><code>&lt;.SINode&gt; &lt;.SIUserMeta&gt;a lot of meta&lt;./SIUserMeta&gt; &lt;.SIUserData&gt;BBB&lt;./SIUserData&gt; &lt;./SINode&gt; </code></pre> <p>is unmarshalled in an object with an empty StorageInterfaceData content attribute.</p> <p>I believe the problem affects the handling of byte[] since I tryied to change the type of StorageInterfaceData content attribute in a String end everything works fine :S .</p> <p>It follows the code.</p> <p><strong>node</strong></p> <pre><code>@Entity @Table(name="sinode") @XmlRootElement(name="SINode") public class StorageInterfaceNode extends BulkObject implements Serializable{ private Integer id; private String name; private StorageInterfaceMetadata metadata; private StorageInterfaceData data; public StorageInterfaceNode() { super(); // TODO Auto-generated constructor stub } public StorageInterfaceNode(Integer id, String name, StorageInterfaceMetadata metadata, StorageInterfaceData data) { super(); this.id = id; this.name = name; this.metadata = metadata; this.data = data; } @Id @GeneratedValue(strategy=GenerationType.AUTO) @Column(name="id", unique=true, nullable=false) @XmlTransient public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } @XmlTransient @Column(name="name", unique=true) public String getName() { return name; } public void setName(String name) { this.name = name; } @OneToOne(cascade= CascadeType.ALL) @XmlElement(name="SIUserMeta") public StorageInterfaceMetadata getMetadata() { return metadata; } public void setMetadata(StorageInterfaceMetadata metadata) { this.metadata = metadata; } @OneToOne(cascade= CascadeType.ALL) @XmlElement(name="SIUserData") public StorageInterfaceData getData() { return data; } public void setData(StorageInterfaceData data) { this.data = data; } } </code></pre> <p><strong>data</strong></p> <pre><code>@Entity @Table(name="data") public class StorageInterfaceData extends BulkObject implements Serializable{ private Integer id; private String dataName; private byte[] content; public StorageInterfaceData() { super(); // TODO Auto-generated constructor stub } public StorageInterfaceData(byte[] content) { super(); this.content = content; } @Id @GeneratedValue(strategy=GenerationType.AUTO) @Column(name="id", unique=true) @XmlTransient public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } @Column(name="name", unique=true, nullable=false) @XmlTransient public String getDataName() { return dataName; } public void setDataName(String dataName) { this.dataName = dataName; } @Column(name="content", nullable=false) @XmlValue public byte[] getContent() { return content; } public void setContent(byte[] content) { this.content = content; } } </code></pre> <p><strong>bulkobject</strong></p> <pre><code>@XmlTransient public class BulkObject { private Integer id; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } } </code></pre> <p>metadata class is omitted not to be too verbose. Can anyone clear the thing please?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
