The bloated JFileChooser seems to be missing one feature: a way to suggest the file name when saving a file (the thing that usually gets selected so that it would get replaced when user starts typing).
Do you know a way around this?
TIA.

i wrote a class that tests for equality, less than, and greater than with two doubles in java. My general case is comparing price that can have an accuracy of a half cent. 59.005 compared to 59.395. Is the epsilon i chose adequate for those cases? thanks...

Here's the basic idea:
There is a java window (main) that opens another java window (child). When the child is created, part of the initialization sets the focus in the appropriate text field in the child window:
childTextField.requestFocusInWindow();
childTextField.setCaretPosition(0);
The child is generally opened through a seriou...

I have an Array of Objects that need the duplicates removed/filtered.
I was going to just override equals & hachCode on the Object elements, and then stick them in a Set... but I figured I should at least poll stackoverflow to see if there was another way, perhaps some clever method of some other API?

I've been trying to find information on this, but due to the immaturity of the Spring Integration framework I haven't had much luck.
Here is my desired work flow:
New files are placed in an 'Incoming' directory
Files are picked up using a file:inbound-channel-adapter
The file content is streamed, N lines at a time, to a 'Stage 1' chan...

I'm using JavaMail to send email requests to an SMTP server. I'm setting both "mail.smtp.connectiontimeout" and "mail.smtp.timeout" properties to 5 and 30 seconds respectively and passing both of these to Session.getDefaultInstance(). However, when I go to do the Transport.send(), the timeouts I set appear to be ignored and it's taking...
For my application, I want a Combo Box that displays its elements when dropped down as a Tree. Problem is, I'm not versed well enough in Swing to know how to go about doing this. At least without ending up writing a new widget from scratch, or something to that effect.
How would I do something like this without creating one from scrat...
