Constructor Detail

ServletRequestDataBinder

public ServletRequestDataBinder(java.lang.Object target,
                                java.lang.String name)

Method Detail

bind

public void bind(javax.servlet.ServletRequest request)

Bind the parameters of the given request to this binder's target. This call can create field errors, representing basic binding errors like a required field (code "required"), or type mismatch between value and bean property (code "typeMismatch").

Parameters:

request - request with parameters to bind

closeNoCatch

public void closeNoCatch()
                  throws ServletRequestBindingException

Treats errors as fatal. Use this method only if it's an error if the input isn't valid. This might be appropriate if all input is from dropdowns, for example.

Throws:

ServletRequestBindingException - subclass of ServletException on any binding problem
