But additionally there are a couple of servlets that a deploy in the same war file that produce some raw data for AJAX-scripts. Currently one can bypass the authentication from WebSphere Portal if one knows the URL to that particular servlet. I want to change this and check if the user is currently logged in to the Portal. How do I do this? I tried ((PumaHome) new InitialContext().lookup(new CompositeName(PumaHome.JNDI_NAME)))

I have tried rewriting the URL, using the "from" & "to" tags, but in vain. I don't know what is the actual & correct way of doing this, as I'm a newbie in Magento. Please anybody provide some good fundamental & correct answer, so that at least the concept gets clear. Also, if possible, please tell me, what is the actual purpose of the controller, for both the frontend & the back-end? Any help is greatly appreciated. 回答1

I'm trying to keep my parent DIV (and children) in focus until I focus out of the div, and it seems surprisingly hard to accomplish. This solution I thought would work but it looks to only applies to sibling elements and not the actual div itself. Here's a demo of what I'm trying to do http://jsfiddle.net/nosfan1019/9Eg3k/3/ . I need it so you can click on the gray portion and not have it disappear. 回答1: Okay, I think that this is what you want: Demo: http:/

I have a specific example, however, and was hoping I can make clean and Pythonic code out of it: #lst is an arbitrary iterable #f must return the smallest non-zero element, or return None if empty def f ( lst ): flt = filter ( lambda x : x is not None and

For exemple, UserA want to display dates like MM/dd/yyyy and UserB want to display dates like dd/MM/yyyy. To do this, I use this thymeleaf parameter : th:value="${#dates.format(myDate, dateFormat)}" The value "dateFormat" is based on the user preference. This works fine. My problem is that the date input is in a form, and when I submit the form, it doesn't take the good format. I always get MM/dd/yyyy
