    <p>I know this question has been asked quite a few times over here, but none of the solutions seemed to worked for me. Pardon me for asking this one again as I am new to both maven and hibernate.</p> <p>hibernate dependency in pom.xml</p> <pre><code>&lt;hibernate.version&gt;4.2.0.Final&lt;/hibernate.version&gt; &lt;dependency&gt; &lt;groupId&gt;org.hibernate&lt;/groupId&gt; &lt;artifactId&gt;hibernate-entitymanager&lt;/artifactId&gt; &lt;version&gt;${hibernate.version}&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.hibernate&lt;/groupId&gt; &lt;artifactId&gt;hibernate-validator&lt;/artifactId&gt; &lt;version&gt;${hibernate.version}&lt;/version&gt; &lt;/dependency&gt; </code></pre> <p>This gives me following jars:</p> <pre><code>hibernate-entitymanager-4.2.0.Final hibernate-core-4.2.0.Final hibernate-validator-4.2.0.Final hibernate-jpa-2.0-api-1.0.1.Final </code></pre> <p>I also have:</p> <pre><code>hibernate-commons-annotations-4.0.1.Final </code></pre> <p>But I am not sure how I got it.</p> <p>I am using the one-to-one relationship for a Category - Product relationship.</p> <pre><code>@Entity @Table(name="Products") public class Product { @Id @Column(name="id") @GeneratedValue int productId; @NotEmpty @Length(max=50) @Column(name="name") String name; @Column(name="category_id") int categoryId; @OneToOne @ForeignKey(name="categoryId") private Category category; // getters and setters } </code></pre> <p>Edit:</p> <p>Since it is clear that Weblogic 11g jpa jar is taking precedence over the 'hibernate-jpa-2.0-api'. Should I fallback to an older version of hibernate that uses jpa-1.0 or is there a way I can enforce weblogic to use 'hibernate-jpa-2.0-api' instead of its jpa jar?</p>

    1. COI guess that additionally to maven configuration you have some code. Could you try to search for `ophranRemoval` and share results with the comunity?

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.
