tag

[Matt Sales <sa...@sealsco.com>]

Hello,
I'm having trouble with the <html:file> tag...

Here's a snippet of my jsp:

<html:form method="POST" action="/saveAction.do"
enctype="multipart/form-data">
    <html:file property="file"/>
...
</html:form>

I've also tried the <html:file> tag using the accepts attribute,
accepts="java.io.File", and
accepts="java.io.String",
with, of course, the corresponding property in the actionForm set to the
correct type.

Every time the form is submitted, I get a Servlet Exception:
BeanUtils.populate and ArgumentTypeMismatchException.
Am I missing something here?  Should the type of the upload actionForm
property be File? String?  something else?

If anyone knows of any documentation out there about this, I'd appreciate
it.

Thanks,
Matt

something else: org.apache.struts.upload.FormFile

Struts uses a user-configurable implementation of type 
org.apache.struts.upload.MultipartRequestHandler as a factory which 
produces an implementation of FormFile from the HttpServletRequest. 
You rarely have to worry about this detail, but you can set an 
alternative MultipartRequestHandler in the <controller> section of 
your struts-config.xml file.

All you really care about is that when you get the ActionForm in your 
Action, it has a property of type FormFile.

Hope that helps.

Joe

What I do:

JSP file:

<html:form method="post" action="/upload" enctype="multipart/form-data" >
<table border="0" cellpadding="0" cellspacing="0" width="100%">
                 <tr>
                   <td colspan="5"><html:file property="theFile" /></td>
                   <img src="picts/blind.gif" width="30" height="1" border="0">
                   <td><html:submit value=" Go " /></td>
                 </tr>
</table>
</html:form>



UploadActionForm:

protected FormFile theFile;

with get/set methods




UploadAction:perform:

if ( file != null )
{
...
stream = file.getInputStream();

zipFile = new File( user.path, user.kurzname + "-upload.zip" );
bos = new BufferedOutputStream( new FileOutputStream( zipFile ) );

int bytesRead = 0;
int count = 0;
byte[] buffer = new byte[ 8192 ];
while ( ( bytesRead = stream.read( buffer, 0, 8192 ) ) != -1 )
{
bos.write(buffer, 0, bytesRead);
count += bytesRead;


and so on...
