Extra character(,) is added while using Textbox in spring - spring

Question

I am new to JSP and Spring. I want to insert a userID(U0005) using textbox in spring form but it is storing(,U0005). From where the "," is inserted?
The code I have written is:
/* In Register.jsp: */
<c:url var="addAction" value="/libUsr/add"></c:url>
<form:form action="${addAction}" commandName="libUsr">
<table>
<tr>
<td>
<form:label path="id">
<spring:message text="ID" />
</form:label>
</td>
<td><form:input path="id" required="true" /></td>
</tr>
</table>
</form:form>
/*
In UserController.java:
*/
#RequestMapping(value= "/libUsr/add", method = RequestMethod.POST)
public String addLibUsr(#ModelAttribute("libUsr") LibUsr libUsr){
libUsrDAO.saveOrUpdate(libUsr);
return "redirect:/register";
}
/*
In DAOImpl:
Saving the data through DAOs
*/
#Transactional
public void saveOrUpdate(LibUsr libusr) {
sessionFactory.getCurrentSession().saveOrUpdate(libusr);
}

Your problem is with this tag:
<form:label path="id">
As you are adding the attribute path to one label, which wont store any value, spring try to get the value and returns empty,yourID.
Change the path attribute of your label to:
<form:label for="id">
<spring:message text="ID" />
</form:label>
If you want to show the value of the id into that label use:
<label>${yourObject.id}</label>
or
<label th:value="${yourObject.id}"></label>
Path attribute is just for input, select, checkbox...not static values as label, span...
