JSF2+RichFaces 4.0: fileUpload

[apostle]

Hello, Dear Community,

I need single file to be upload to a server from a page. I tried using fileUpload richfaces component but was failed to adjust it accordingly. Is it possible to make my own component to upload only one file when form is submitted or use some from external framework?

I also tried to implement file uploading like it is suggested here http://ironicprogrammer.blogspot.com/2010/03/file-upload-in-jsf2.html, but even if I added "multipart/form-data" enctype for a form and use a4j:commandButton request content type is always "application/x-www-form-urlencoded" not "multipart/form-data". If I use h:commandButton the request type is "multipart/form-data", but action from back-end bean is never called

Below is a part of JSF with two buttons

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

            <h:panelGroup id="mainPanel">

                <h:panelGrid columns="1">

                    <h:outputLabel for="name" value="#{msg['name']}"/>

                    <h:inputText value="#{documentController.name}" id="name"/>

                    <rich:message for="name" styleClass="err"/>

                </h:panelGrid>

                <input type="file" name="vcardFile"/>

                <a4j:commandButton value="#{msg['save']}" action="#{documentController.uploadFile}" />

                <h:commandButton action ="#{documentController.uploadFile}" value="Submit"/>

            </h:panelGroup>

        </h:form>

Please, give me any tip how can I make it work or provide any solution for a single file upload.

Thanks

Hi Pavel,

a4j's application/x-www-form-urlencoded comes from the Ajax-Request. There are other components like Tomahawk that support direct File-Upload (as you defined in your code snippet, see http://ertantoker.blogspot.com/2009/03/fileupload-mit-apache-tomahawk.html). Tomahawk also provides own commandButtons, but multipart/form-data should work with RF4.

Best regards,

Mark

Hi, Mark,

thanks for your help. In fact Tomahawk inputFileUpload component works with Richfaces 4, but only with h:commandButton. So, there reason why it did not work for me was about using a4j:commandButton. Now what if I want to show a popup window after user uploaded a file? Is it possible with h:commandButton?

Getting an Event after the Upload is complete is difficult. A good approach would be either to redirect the user to a page where the popup is triggered or setting some property in your model and query the model in a JavaScript on your upload page. Since it's a page submit, you're free to do this.

Hi, Mark,

I see your point. Thanks for helping me out.
