    <p>Isn't that an empty while loop?</p> <p>you have:</p> <pre><code>try { ...code } finally { } while (something); </code></pre> <p>put some whitespace in there, and you actually have:</p> <pre><code>try { ...code } finally { } while (something) ; </code></pre> <p>your while loop isn't related to your try/finally. if your original try statement fails and the file isn't created, that while loop will never complete, because the try/finally will never execute a second time.</p> <p>did you intend to make that a do{ all your code } while (your while statement)? because that isn't what you have there.</p> <p>EDIT to clarify: my suggestion would be to change your while loop to have more info of why it can't delete:</p> <pre><code>while (!file.delete()) { if (!file.exists()) break; // the file doesn't even exist, of course delete will fail if (!file.canRead()) break; // the file isn't readable, delete will fail if (!file.canWrite()) break; // the file isn't writable, delete will fail } </code></pre> <p>because if delete fails once, its just going to fail over and over and over, of course its going to hang there. you aren't changing the state of the file in the loop.</p> <p>Now that you've added other info, like Tomcat, etc, is this a permissions issue? are you trying to write to a file that the user tomcat is running as (nobody?) vm can't create? or delete a file that the tomcat process can't delete?</p> <p>If process explorer/etc say java has a lock on the file, then something still has an open stream using it. someone might have not properly called close() on whatever streams are writing to the file?</p>

    1. COThe while loop isn't empty, exactly. It says, while the file isn't successfully being deleted, try again to delete it.

    2. COYes, your while isn't "empty", but your while is "dumb". its checking the exact same state over and over, and the inside of the while loop doesn't do anything to change it. how many times do you want the OS to tell you "you can't delete that file" without putting in some code to figure out why?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
