It's not a Struts bug, and it's not even a Struts-related problem. Any time you need to upload files, you must use a POST request with an 'enctype' of "multipart/form-data". Your form element should look like this:
<html:form action="/imageUpload.do" type="imageUploadForm" enctype="multipart/form-data"> -- Martin Cooper "Bryan Hunt" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > Hi there list, > I have been trying to get the most simple file upload example working with > and have been receiving a strange error message that I just can't seem > to shake. > > Here is the basics of my action form > snip= > public class ImageUploadForm extends ActionForm { > // --------------------------------------------------------- > Instance Variables > /** imageFile property */ > protected FormFile file; > > // --------------------------------------------------------- Methods > > public ActionErrors validate( > ActionMapping mapping, > HttpServletRequest request) { > > if(file == null){ > System.out.println("file is empty"); > } > return null; > } > > public FormFile getFile() { > return file; > } > > public void setFile(FormFile file) { > this.file = file; > } > =snip > > Here is the basics of the action > snip= > public ActionForward execute( > blah) { > System.out.println("at least i managed to get called"); > throw new UnsupportedOperationException("Generated method > 'execute(...)' not implemented."); > } > =snip > > Here is the basics from my struts config file > snip= > <form-bean name="imageUploadForm" > type="ie.jestate.struts.form.ImageUploadForm"> > <form-property name="file" > type="org.apache.struts.upload.FormFile" /> > </form-bean> > <action > attribute="imageUploadForm" > input="/form/imageUpload.jsp" > name="imageUploadForm" > path="/imageUpload" > type="ie.jestate.struts.action.ImageUploadAction" > scope="request" > validate="true" > > > <forward name="imageuploadsuccess" > path="/form/imageUpload.jsp" /> > </action> > =snip > > Here is the jsp file > > snip= > <%@ page language="java"%> > <%@ taglib uri="http://jakarta.apache.org/struts/tags-bean"; prefix="bean"%> > <%@ taglib uri="http://jakarta.apache.org/struts/tags-html"; prefix="html"%> > <html> > <head> > <title>JSP for imageUploadForm form</title> > </head> > <body> > <html:form action="/imageUpload.do" type="imageUploadForm" > > File : > <html:file property="file"/> > <html:submit/> > </html:form> > <body> > </html> > =snip > > And here is the abreviated version of the error message > snip= > > *exception* > > javax.servlet.ServletException: BeanUtils.populate > org.apache.struts.util.RequestUtils.populate(RequestUtils.java:1254) > org.apache.struts.action.RequestProcessor.processPopulate(RequestProcessor.j ava:821)* > > cause mère* > > java.lang.IllegalArgumentException: argument type mismatch > sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > =snip > > I have tried changing the type to text and the type to String in > the form and that works but use this FormFile class and everything > seems to go fubar. > > > It never even gets to call the action , instead it generates this error > message , > but the setters and getters are right and the variable is public, this > only happens > with the FormFile.
