My FileDownload Ability now works. But still one problem occurs:
I represent the uploaded Files in a Datatable. There is also a delete Button,
which moves the file into an "old" directory.
When I now first open the file with the open button and THEN afterwards I want
to delete the file, i get the little window for opening the file AGAIN?
(Nevertheless the file is moved into the old directory...)
I have no found out, that the problem occurs because of a Confirm Message which
I have on the JSF Page:
If I delete the onclick="Return confirmSubmit()" Javascript Function, then
everything works...
Is there a possiblity to "Kill" the former submit, so that it doesn't come up
again?
Here is the JSF PAGE CODE:
<h:commandButton onclick="return confirmSubmit()"
image="images/loeschen.gif"
action="#{detailsDto.deleteDatenblaetter}">
<t:updateActionListener
property="#{detailsDto.dashId}"
value="#{rowItem[0]}" />
<t:updateActionListener
property="#{detailsDto.uploadFileDirectory}" value="#{rowItem[3]}" />
<t:updateActionListener
property="#{detailsDto.uploadFileName}"
value="#{rowItem[4]}" />
</h:commandButton>
Here is the code for deleting the Datasheet:
public void deleteDatenblaetter() throws Exception {
Session session = HibernateUtil.currentSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
EtDatasheets datasheet = (EtDatasheets) session.get(
EtDatasheets.class, dashId);
session.delete(datasheet);
File newdirectory = new File(directory +
"old\\datasheets");
newdirectory.mkdirs();
//String sNewFile = uploadFileDirectory.substring(5);
String sNewFile = uploadFileDirectory;
File in = new File(sNewFile);
FileInputStream fis = new FileInputStream(in);
File out = new File(directory + "old\\datasheets\\"
+ new Date().getTime() + "_" +
uploadFileName);
FileOutputStream fos = new FileOutputStream(out);
byte[] buf = new byte[1024];
int i = 0;
while ((i = fis.read(buf)) != -1) {
fos.write(buf, 0, i);
}
fis.close();
fos.close();
in.delete();
tx.commit();
}
catch (Exception ex) {
if (tx != null)
tx.rollback();
msg = bundle.getString("errorDeleteDatasheet");
context.addMessage(null, new FacesMessage(
FacesMessage.SEVERITY_WARN, msg, null));
throw ex;
}
finally {
HibernateUtil.closeSession();
}
}
Thx for help!
Regards,
Andy
