java - Where to fit in Jasper Reports - front end or business? -

-

I'm trying to use Jesper reports (v3.5.2) Web app This webpage already uses JSF (woodstock) for front-end and a MySQL db with EJB3 (with JApa and as a hibernate provider firm).

My question is - Where to beat the code for the creation of Jasper based reports? I'm completely confused about it. Should I put it in JSF Front End? Or should it be a "report" module in business logic as the session's beans?

I would think that the right place for this is the business level as a separate module. I will call a business method with the name of the input method map and report format as the parameters of the business method. And in return, I can get PDF / html generated, after which I can send it to the browser. Am I on the right track with it?

Can you suggest ways to do this?

In addition to this, I would like to use EJBUL because I already have JpA

Thank you.

If you are going to embed jsper as part of your ear, then I would say that it should be flat in a class as you suggest. I am not sure that I will make a separate EJB for it, unless you are clustering or otherwise going to offload the report generation on any other JVM, or you need some special transaction.

Another common option is completely a separate report server that you will call from far away, and it will interact with the user.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
