struts.xml redirect action with 'file' param?

Question

Assume I have an action to validate a form. If this method returns success, it is being redirected to a new action with all its parameters. One of my parameters is of type:

java.io.File

And this causes the redirected action to return INPUT instead of SUCCESS.

Here's my code:

   public String validateMemberForm() {
    int fails = 0;
    if (service.findMemberByCompany(company) != null) {
        addFieldError("company", "This company is already registered!");
        fails++;
    }
    if (service.findMemberByEmail(email) != null) {
        addFieldError("email", "This email is already registered!");
        fails++;
    }
    if (fails != 0) {
        return INPUT;
    }
    return SUCCESS;
}

My redirect inside struts.xml:

<action name="validate_member" class="managementAction" method="validateMemberForm">
        <result name="success" type="redirectAction">
            <param name="actionName">create_member</param>
            <param name="company">${company}</param>
            <param name="upload">${upload}</param> <!-- THIS PARAM IS OF TYPE FILE -->
            <param name="uploadContentType">${uploadContentType}</param>
            <param name="uploadFileName">${uploadFileName}</param>
            <param name="email">${email}</param>
        </result>
        <result name="input">/pages/authenticated/memberSave.jsp</result>
    </action>

And my 'create_member' action returns INPUT.

Not to be overtly picky but why not just use: public void validate() method to contain your field error code? See: http://struts.apache.org/release/2.3.x/docs/form-validation.html then you don't need the redirect and the action dedicated to validation only. — Quaternion, Dec 02 '14 at 19:34
HTTP params are strings. You can't redirect with a file in any meaningful way. — Dave Newton, Dec 02 '14 at 19:59
Thanks. @Quaternion I want my class to contain more than one actions, that's why I do not use void validate(). — Bravo, Dec 02 '14 at 22:37
You can use the validateXxx() form to include multiple validation methods into one class... Dave pointed out the redirect limitation but if you insist on this separation you could chain... — Quaternion, Dec 02 '14 at 23:47
Cheers @Quaternion. Didn't know about this approach, this has solved my problem. — Bravo, Dec 03 '14 at 00:25
