If it's too much to post here, it's too much for me to go through I'm afraid.

Well, currently your ResizeImage method (should be resizeImage, to fit with standard naming practices) accepts both a path and a byte[].
When you want the default image then, if byte[] is null, give that method the path to the default image instead.

Indeed, I would split the resizeImage up.  It's currently doing too much, in my opinion.

First, the resize:

Then supply two methods to get an image:


Depending on where these live, I wouldn't expect them to be public methods, but I don't know your code structure.

ETA: This lot is hand written, so apologies for any compilation issues.

Nothing there is doubling the last digit.
What is the full output from that code?
Can you also print the card number in the constructor so you can see exactly what it is receiving?

There's nothing to stop you having a dummy image to use.
No point storing that in the database, just display it if the employee record has no image associated with it.

true, but I'm pretty sure I've never seen:

Lines 40 and 41 in the first bit of code assume you have a valid image file.
You need to check whether or not one has been supplied.
If it isn't then don't try and create an input stream...I think (though cannot guarantee) that you can just set the Blob to null in that case.

The error should have given you a stack trace, by the way, which would have helped to point us to where in the code you were getting this error.
Alway give the stacktrace, along with the full error message.

Then only shuffle once, picking th next item in the List each time they click the button.

Of course you then need to decide what to do when you get to the end of the List.

But you haven't got any repeating array items.

All those Quote instances are unique, so you won't get repeats from a shuffle of the array.

By the way, the last two should be attributed to Pilsudski, at a guess, and not Einstein.

Do any of your debug statements appear in your logs?
What happens on the browser?

Have you used the browser tools (F12) to see what is happening on the network (ie what requests and response are being made)?

It happened because somewhere inside the getInstance() method a GregorianCalendar is created and returned.

No, that's fair enough, I just couldn't see the route to get the null.
Should have figured it out, as it's similar to the old singleton issue.

Any hints what it ought to look like to see the issue?
I mean, download Tomcat and start it up.
Deploy your app to Tomcat.

That way I know when I deploy to Tomcat elsewhere it'll work, and Eclipse isn't hiding an issue.

When you say it worked under Eclipse, I assume this was the built in Tomcat?

Did you try and deploy to a local standalone Tomcat to ensure that deployment would work?
