How to provide/pass filenames to af:fileDownloadActionListener method.

Question

Hi,
I have a use case that lets the user download a list of files that are in the filesystem.
Is there a way to pass the file names to the af:filedownloadActionListener method?
<af:commandButton value="Download File 1">
<af:fileDownloadActionListener filename="file1.txt"
contentType="text/plain; charset=utf-8"
method="#{myBean.doDownload}"/>
</af:commandButton>
<af:commandButton value="Download File 2">
<af:fileDownloadActionListener filename="file2.pdf"
contentType="text/plain; charset=utf-8"
method="#{myBean.doDownload}"/>
</af:commandButton>
Can I access the filename attribute of af:fileDownloadactionListener programmatically somehow?
public void doDownload(FacesContext facesContext, OutputStream out) {
try {
FileInputStream fis;
fis =new FileInputStream(Filename????); // how does one get the file name
int n;
byte[] b;
while ((n = fis.available()) > 0) {
b = new byte[n];
int result = fis.read(b);
out.write(b, 0, b.length);
} catch (IOException e) {e.printStackTrace();}
Please help with any suggestion, examples or links.
Thanks

Hi All,
Does anyone have an idea on how to resolve of passing download file name to the fileDownloadActionListener action? Frank suggested using memory attribute, but I do not know to do that. Can any one show me how to accomplish that.
Thanks,
