Validation in Spring 3.x using @Valid annotation:
Below is snippet from the messages_en.properties. I have a form having Username and Password field. When user does not enter anything in Username field, it displays both these messages one below other.

NotEmpty.loginBean.username=Username cannot be Empty
Size.loginBean.username=Size must between 5 to 50 characters.

Any HTML tag given in the message.properties is not interpreted.

NotEmpty.loginBean.username=<li>Username cannot be Empty</li>

Above would display <li> as it is.
Questions:
1) Is there any ways to interpret HTML tag and display its output?
2) Can i show single message though both validation fails?

    Ad. 1) Yes, use htmlEscape="false":

    <form:errors path="nip" cssClass="error" htmlEscape="false" />

    Ad. 2) This is actually JSR303’s Achilles’ heel – it can be done, but is neither easy nor clean (see this issue). Order of validating each annotated field is undefined, so trick is to use @GroupSequence and custom groups like described here or here.

    Alternative solution would be to use custom annotation with @ReportAsSingleViolation, but it will not distinct NotEmpty and Size errors as it’ll have its own error message.
