    <p>I am using Struts 2.3.7, struts2-jquery-grid-plugin-3.5.0 and hibernate 3.6. I want to show data on <code>jqgrid</code> which is coming from two different tables.</p> <p>My problem is that I have to show two tables data in one <code>jqgrid</code> .First three <code>jqgrid</code> column is filled by <code>Issue</code> table and last Column <code>name="assignedTo"</code> is filled by <code>Issue_Tracker</code> table. How to show the data in last column i.e. <code>assignedTo</code>. Any help would be appropriated.</p> <p><strong>My jqgrid is</strong> </p> <pre><code>&lt;sjg:grid id="gridtable" caption="Issue-Summary" dataType="json" href="%{remoteurl}" pager="true" gridModel="gridModel" rowList="10,15,20" rowNum="15" rownumbers="true" reloadTopics="reloadGrid" &gt; &lt;sjg:gridColumn name="issue_id" id="issueId" index="id" title="Issue-ID" formatter="integer" sortable="false"/&gt; &lt;sjg:gridColumn name="issue_description" index="id" title="Issue-Details" sortable="false"/&gt; &lt;sjg:gridColumn name="issue_raised_date" index="date" title="Issue-Date" formatter="date" sortable="false"/&gt; &lt;sjg:gridColumn name="assignedTo" index="assigned" title="Assigned To" sortable="false"/&gt; &lt;/sjg:grid&gt; </code></pre> <p><strong>I have pojo's:</strong></p> <p>Issue.java</p> <pre><code>public class Issue implements Serializable { private Integer issue_id; private String issue_description; private Date issue_raised_date; getters and setters </code></pre> <p><strong>another pojo is</strong> </p> <p>Issue_Tracker.java</p> <pre><code>public class Issue_Tracker implements Serializable { private Integer issue_id; private String assignedTo; </code></pre> <p><strong>and My Dao is as follows to show the list of Issues in jqgrid</strong></p> <pre><code>public List&lt;Issue&gt; showHelpDeskIssues(DetachedCriteria dc, int from, int size) { Session session = HibernateUtil.getSessionFactory().getCurrentSession(); try { Criteria criteria = dc.getExecutableCriteria(session); criteria.setFirstResult(from); criteria.setMaxResults(size); criteria.add(Restrictions.eq("status","Escalate To")); return criteria.list(); } catch (HibernateException e) { e.printStackTrace(); throw e; } } </code></pre>

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.
