    <p>I have a shopping cart application where in the items are displayed as rows of a table. At the end of each row, there is an "Add to Cart" submit button. Currently, when I click that button the entire page disappears and an error 404 page appears as the form is submitted to the servlet. What I want is that when one row is submitted, the rest of the rows remain and only the clicked row changes color. As the user adds more rows(items), each one of those rows should change color. I have got the changing color part, but have not been able to figure out how to make the rest of the rows stay on the page. </p> <pre><code> &lt;h1&gt; Here is the product list as per your category selection&lt;/h1&gt; &lt;table cellpadding="10" border="1" id="tbl"&gt; &lt;tr valign="bottom" style="background-color: #FF00FF"&gt; &lt;th align="left"&gt;Sl No&lt;/th&gt; &lt;th align="left"&gt;Prod ID&lt;/th&gt; &lt;th align="left"&gt;Unit Price&lt;/th&gt; &lt;th align="left"&gt;Quantity&lt;/th&gt; &lt;th align="left"&gt;&lt;/th&gt; &lt;/tr&gt; &lt;form name="tableForm" &gt; &lt;c:forEach items="${listInServlet1}" var="regBean"&gt; &lt;tr style="background-color: #00FFFF"&gt; &lt;input type="hidden" value="sval" name="qtyTextHidden" /&gt; &lt;input type="hidden" name="reagentId" value="&lt;c:out Value = " ${regBean.prodId} "/&gt;" /&gt; &lt;td&gt; &lt;c:out Value="${regBean.prodCount}" /&gt; &lt;/td&gt; &lt;td&gt; &lt;c:out Value="${regBean.prodId}" /&gt; &lt;/td&gt; &lt;td&gt; &lt;c:out Value="${regBean.price}" /&gt; &lt;/td&gt; &lt;td&gt; &lt;input name="qtyText" type="text" size="2" value="" onChange="calculateTotalPrice(this, '${regBean.price}')" /&gt; &lt;/td&gt; &lt;td&gt; &lt;input name="totalprice" type="text" size="2" value="0" /&gt; &lt;/td&gt; &lt;td&gt; &lt;input type="submit" value="Add to Cart" name="addToCrtBtn" onClick="submitValues(event, '${regBean.prodCount}', '${regBean.price}')" /&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/c:forEach&gt; &lt;/form&gt; &lt;/table&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt; &lt;form name="tableForm" method="post" action="/myapp/myservlet"&gt; &lt;input type="submit" value="Done" id="submitOrder" /&gt; &lt;/form&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
