RE: Flowscript - delete file
Hi Peter,
I did not test the script I wrote actually and I can tell you why the script
runs into an error.
.delete() is also a javascript method on an object. It will delete a property
by the name you specify. As you clearly want to call the delete method on the
file you need to use the workaround you used.
Kind regards,
Robby

Subject: Re: Flowscript - delete file
Hi Martin and Robby,
Thank you both for your help, what I have ended up with is:
importClass(Packages.java.io.File);
importClass(Packages.java.io.FileNotFoundException);
function deletefile() {
//var filePath = cocoon.parameters["file"];
var filePath = "D:/cocoon-2.1.11-wl/build/webapp/B&B/xml/.xml"; //for
testing
var file = new File(filePath);
try {
if (!file.exists()) {
throw new FileNotFoundException(filePath);
}
file.delete();
cocoon.sendPage('deletefilesuccess',{file:filePath});
} catch (e) {
cocoon.sendPage('deletefileerror',{file:e});
}
}
However, file.delete(); produces a syntax error.
If I comment out file.delete(), the rest of the script works correctly:
* If .xml exists, deletefilesuccess is accessed
* If .xml does not exist, deletefileerror is accessed and I get:
Error File java.io.FileNotFoundException:
D:/cocoon-2.1.11-wl/build/webapp/B&B/xml/.xml Not Found
What's wrong with file.delete(); ?
Regards
Peter

Hi Peter,
Ok, I missed something:
var xml_file =
Packages.java.io.File("D:\cocoon-2.1.11-wl\build\webapp\B&B\xml" + file +
".xml");
should be:
var xml_file = new
Packages.java.io.File("D:\cocoon-2.1.11-wl\build\webapp\B&B\xml" + file +
".xml");
But you should try the function Robby sent to the list. It's much
cleaner.

Try
xml_file.delete();
You just have to add the full "path" to the class when you
construct it. After this, the variable contains a reference and you
can just use it.

Re: Flowscript - delete file
Hi Peter, It's not flowscript, but I believe one can also use the source-writing transformer to delete xml files from the filesystem: ... context://doc/editable/my.xml ... One can insert the exact filename via a sitemap parameter/xslt variable earlier in the chain, then use: to delete. See: https://cocoon.apache.org/2.1/userdocs/sourcewriting-transformer.html Dan On 2012-12-29 3:05 AM, Peter Sparkes wrote: Solved I found the answer at http://markmail.org/message/7psype56uhu5kbad#query:+page:1+mid:ezqkl6i255bjdw75+state:results I amended file.delete(); to: file["delete"](); and it works, the file is deleted.

Re: Flowscript - delete file
Solved
I found the answer at
http://markmail.org/message/7psype56uhu5kbad#query:+page:1+mid:ezqkl6i255bjdw75+state:results
I amended file.delete(); to:
file["delete"]();
and it works, the file is deleted. However, I don't know why it works

Re: Flowscript - delete file
Hi Peter,
file.delete() doesn't get executed in this case.
Its:
if (!file.exists()) {
throw new FileNotFoundException(filePath);
that line of code that triggers your Error message and file.delete() has
not been reached.

Greg
