UpLoadForm代码

package com.DBConn.struts;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionForm;

public class UpLoadForm extends ActionForm {

private static final long serialVersionUID = 1L;
protected FormFile theFile;


private String InType;


public ActionErrors validate(ActionMapping actionMapping,
HttpServletRequest httpServletRequest) {

return null;
}


public void setInType(String InType) {
this.InType = InType;
}


public String getInType() {
return InType;
}

public FormFile getTheFile()
{
return theFile;
}

public void setTheFile(FormFile theFile)
{
this.theFile = theFile;
}

public void reset(ActionMapping actionMapping,
HttpServletRequest servletRequest) {
}

}


为什么红色的地方打印出来的值为null


我想把所属分类选中的值传过来，
谢谢了！
