How to implement multiple files upload

Question

RichFaces has a cool component for uploading multiple files with flash. But we use ADF and we need to deploy it on a 10G server. With multiple upload I mean that it should be possible to press a browse button and in the file dialog select multiple files instead of the standard one file.
Do you know any open source flash fileupload applications and do you have an example of how to integrate it with ADF?

Answer 1

I have done that but rather then using a single <af:inputFile> to upload a file i have used multiple of the same and set their rendered property as true when user clicks on add another attachments. The trick to call a java method from the doDML method of entity object and writing your custom logic their. Also you need to used Partial Submit =true on the Submit button of the creation page so that page does not get submited and you do not loose the Uploaded File Objects when you press commit button.
How to call method from doDML
make your backing bean scope as session
protected void doDML(int operation, TransactionEvent e) {
if(operation==1){
FacesContext ctx = FacesContext.getCurrentInstance();
Class c[]=new Class[3];
String s="rohit";
oracle.jbo.domain.Number n=new oracle.jbo.domain.Number();
c[0]=s.getClass();
c[1]=s.getClass();
c[2]=s.getClass();
MethodBinding vb = ctx.getApplication().createMethodBinding("#{AddIwoAttachment.insert}",c);
Object para[]=new Object[3];
para[0] = getIwoNo();
para[1]= getProjectNo().toString();
para[2]= getRemarks();
vb.invoke(ctx,para);
// AddIwoAttachment o=(AddIwoAttachment)vb.getValue(ctx.getCurrentInstance());
// System.out.println(o.fileName1);
else{
super.doDML(operation, e);
Where MethodBinding vb = ctx.getApplication().createMethodBinding("#{AddIwoAttachment.insert}",c); creates the methodBinding to the same object whick backs the af:inputFile ActionListener and mehtodBinding .invoke calls the method and para is used to supply other attribute values.
Hope this helps.
