The request sent by the client was syntactically incorrect.-Spring MVC + JDBC Template

Question

I am newbie to Spring MVC. I was stuck by an error while running my project Error-The request sent by the client was syntactically incorrect. I have an enti

Answer 1

In my case, I try to create an object that has ID and NAME as attributes. ID is int, NAME is String. But my js set values like this ID = '', NAME = 'brabrabra...'

After set ID = 0, problem is fixed.

Answer 2

I had a similar issue recently and solved it by annotating my Date field with the @DateTimeFormat. In your case, you would edit your PatientInfo.java file to:

    import org.spring.framework.annotation.DateTimeFormat;

    @Column(name = "DateOfBirth")
    @Temporal(TemporalType.TIMESTAMP)
    @DateTimeFormat(pattern = ${pattern})
    private Date dateOfBirth;

Make sure to replace ${pattern} with a string representing the format that will be received (e.g. "yyyy-MM-dd").

Answer 3

I think the issue is that Spring doesn't know how to deserialize the date your browser client sends when submitting the following input field in

<tr name="tstest">
    <td>Date Of Birth</td>
    <td><form:input path="dateOfBirth" name="timestamp" value=""/>
        <a href="javascript:show_calendar('document.tstest.timestamp', document.tstest.timestamp.value);"><img src="../images/cal.gif" width="16" height="16" border="0" alt="Click Here to Pick up the timestamp"></a>
    </td>
</tr>

Spring doesn't know how to take the value that you enter into that field and convert it into a Date object. You need to register a PropertyEditor for that. For example, add the following to your @Controller class

@InitBinder
public void initBinder(WebDataBinder binder) {
    SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
    sdf.setLenient(true);
    binder.registerCustomEditor(Date.class, new CustomDateEditor(sdf, true));
}

Obviously, change the SimpleDateFormat to whatever your client is sending.

On a related note, you're sending a 302 response by sending a redirect

return "redirect:/full-reg";

Remember that request and model attributes only live for the duration of one request. So when your client send the request to full-reg, none of the form input parameters you sent originally exist any more. You should re-think how you do this.

Answer 4

I came across the same error this morning. The problem with my code was that I had declared a variable as an integer in my form binding object but on the actual form I was capturing text. Changing the variable to the correct type worked out for me

Answer 5

This happens when the defined binding does not match to what the user is sending. The most common issues are:

• Missing PathVariable declaration
• Incomplete PathVariable declaration (for example missing value="variableName")
• Wrong data type, such as Sotirios Delimanolis answer above. If the Class of an input parameter cannot be serialized the request is not processable

So, in general, be sure that:

• Each PathVariable is declared
• A value is assigned that corresponds to value to be match in the path - @PathVariable(value="myVariableName", String myVariable) where the path defines @RequestMapping(value = "/userInfo/myVariableName", method = RequestMethod.GET)
• Each class declared for a PathVariable must be serializable.

Answer 6

try with this (with /add-update2 instead of just add-update2) and replace modelAttribute by commandName

<form:form commandName="patientInfo" method="POST" action="/add-update2">
