Subject RE: Flowscript - delete file
Date Sat, 29 Dec 2012 17:26:57 GMT
Hi Peter,

I did not test the script I wrote actually and I can tell you why the script runs into an

.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,

Hi Martin and Robby,

Thank you both for your help, what I have ended up with is:


function deletefile() {

    //var filePath = cocoon.parameters["file"];

    var filePath = "D:/cocoon-2.1.11-wl/build/webapp/B&B/xml/9999.xml";  //for testing
    var file = new File(filePath);
     try {
        if (!file.exists()) {
           throw new FileNotFoundException(filePath);
    } catch (e) {

However, file.delete(); produces a syntax error.

If I comment out file.delete(), the rest of the script works correctly:

  *   If 9999.xml exists, deletefilesuccess is accessed
  *   If 9999.xml does not exist, deletefileerror is accessed and I get:

Error File D:/cocoon-2.1.11-wl/build/webapp/B&B/xml/9999.xml
Not Found
What's wrong with file.delete(); ?

Hi Peter,

Ok, I missed something:

 var xml_file ="D:\cocoon-2.1.11-wl\build\webapp\B&B\xml" + file
+ ".xml");

should be:

 var xml_file = new"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

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.
