New fileUpload component

[shane.bryzak]

I've committed a basic working version of a fileUpload tag to CVS. It doesn't need all the additional jar files that the tomahawk component requires, and is greatly simplified from the 17 levels of abstraction that the Apache version implements. Usage is as such:

page:

<s:fileUpload id="picture" value="#{register.picture}"/>

web.xml:

<filter>
 <filter-name>Seam Multipart Filter</filter-name>
 <filter-class>org.jboss.seam.servlet.SeamMultipartFilter</filter-class>
 </filter>

 <filter-mapping>
 <filter-name>Seam Multipart Filter</filter-name>
 <url-pattern>*.seam</url-pattern>
 </filter-mapping>

action class:

@Name("register")
public class RegisterAction implements Register
{
 private byte[] picture;

 public void setPicture(byte[] picture)
 {
 this.picture = picture;
 }

 public byte[] getPicture()
 {
 return picture;
 }
}

That's all there is to it. It doesn't do anything fancy yet such as progress notification, etc, or for that matter even store the filename. It would be nice though if someone could give it a try and report back any issues/feature requests either in this thread, or on the following JIRA page:

http://jira.jboss.org/jira/browse/JBSEAM-630

Thanks!

Nice! And may be even just in time :)

One more thing I forgot to mention - the form tag needs to set the encoding type to multipart/form-data:

<h:form enctype="multipart/form-data">
...
</h:form>

Hi,
This fileUpload component is very easy to use, but I am wondering how to get the uploaded file properties, e.g. type, name. Thank you.

This fileUpload component is very easy to use, but I am wondering how to get the uploaded file properties, e.g. type, name. Thank you.

Shane added that last night. It looks like:

<s:fileUpload data="#{component.bytes}" contentType="#{component.type}" fileName="#{component.name}"/>

[gus888]

Very nice. This will be very easy to value-bind file with entity bean. Thank you so much.

I'm using JSF 1.1 RI and the file upload component doesn't work.

It will work just fine if I include the following lines of code in the FileUpload.decode():

 if (request instanceof HttpServletRequestWrapper) { // Needed for JSF 1.1 RI
 request = ((HttpServletRequestWrapper) request).getRequest();
 }

FileUpload.decode():

 @Override
 public void decode(FacesContext context)
 {
 super.decode(context);

 Object request = context.getExternalContext().getRequest();

 if (request instanceof HttpServletRequestWrapper) { // Needed for JSF 1.1 RI
 request = ((HttpServletRequestWrapper) request).getRequest();
 }

 if (request instanceof MultipartRequest)
 {
 MultipartRequest req = (MultipartRequest) request;

 String clientId = getClientId(context);
 byte[] fileData = req.getFileBytes(clientId);
 String contentType = req.getFileContentType(clientId);
 String fileName = req.getFileName(clientId);

 getValueBinding("data").setValue(context, fileData);

 ValueBinding vb = getValueBinding("contentType");
 if (vb != null)
 vb.setValue(context, contentType);

 vb = getValueBinding("fileName");
 if (vb != null)
 vb.setValue(context, fileName);
 }
 }

Dear Shane I have used this component of yours and its working fine.

Can you please tell me, how can we regenerate the saved images in the database to our front end in JSF. Currently i have tried it as:

<h:graphicImage id="image" url="#{hotel.image}">
</h:graphicImage>

but it is not displaying the image, can you please help me in this matter.

Thank you very much
