Why are Bootstrap's form elements rendered terribly with Struts2-Boostrap-Plugin?
When I add struts tags, the formatting disappears. What do I do?
This is my code:
<div class="panel-body" style="background-color:;">
<div align="center">
<font size=3> <s:form id="FormAddUser" name="FormAddUser"
action="AddUser" method="post" class="form-horizontal">
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>User ID</label>
</div>
<s:textfield name="UserId" class="form-control"></s:textfield>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>Name</label>
</div>
<s:textfield name="Name" class="form-control"></s:textfield>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>Address</label>
</div>
<s:textarea name="Address" class="form-control"></s:textarea>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>Birth date</label>
</div>
<s:textfield name="DOB" class="form-control" placeholder="dd/mm/yy"></s:textfield>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>Password</label>
</div>
<s:password name="Password" class="form-control"></s:password>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>Email Id</label>
</div>
<s:textfield name="EmailId" class="form-control"
placeholder="firstname.lastname@iiitb.org"></s:textfield>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>Specialization</label>
</div>
<s:textfield name="Specialization" class="form-control"
placeholder="CS/DS/NC/SE"></s:textfield>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-6">
<div class="col-sm-4" align="right">
<label>Specialization</label>
</div>
<s:file name="Image" class="form-control" id="Image" key="Image"
label="Select a File to change photo" enctype="multipart/form-data"></s:file>
</div>
</div>
<br>
<div class="row" align="center">
<div class="col-sm-7">
<s:submit class="btn btn-primary" label="Add" onclick="check()" />
<a href="admin.jsp" class="btn btn-primary btn-md"> <span
class="glyphicon glyphicon-repeat"></span> Back
</a>
</div>
</div>
</s:form>
</font>
</div>
</div>
</div>
This is how it renders. The problem is because of the struts tags. I have included the struts-bootstrap jar. What could be the possible error?
Struts2 uses Themes to generate HTML from Tags: a different theme chosen, a different HTML in output.
The default theme is XHTML, that generates <td>, <label> and other stuff around your elements.
Usually, I recommend to use the simple theme, that generates almost no additional code, and that would make your code work as-is. Put this constant in struts.xml to check it out:
<constant name="struts.ui.theme" value="simple" />
But in your case, since you said you've included the Struts2-bootstrap-plugin in your project, then... simply use it ! You are NOT using it in your code... including the JAR is not enough, you need to set the bootstrap theme as the default one:
<constant name="struts.ui.theme" value="bootstrap" />
and declare the struts-bootstrap taglib to use the <sb:head/> tag, as described in the official documentation:
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sb" uri="/struts-bootstrap-tags" %>
<!DOCTYPE html>
<html lang="en">
<head>
...
<!-- Le HTML5 shim, for IE6-8 support of HTML elements -->
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<sb:head/>
</head>
<body>
...
</body>
</html>
Then remove all the HTML that you've written manually, and start using the plugin.
