java.lang.AbstractMethodError running a webapp in Eclipse with jetty. -

-

I am working on a project in Eclipse that when I use the JETI plugin, I

< Pre> java.lang.AbstractMethodError: au.com.mycopmpany.impl.MyClassDAOIpl.findById (Ljava / lang / Integer;) Ljava / lang / object;

This file is okay in Eclipse and is implementing the code method that talks about the error. This error indicates to me that "on the runtime" JVM gets a class that has not implemented this method.

But I can assure you that MyClassDAOImpl does most definitely implement the findById method with the correct signature.

This eclipse looks like a bug in the compiler; I can fix this problem by running the maven package from the command prompt and then it works fine to run the app within the Elpsy.

It seems that there is some kind of bug in connection with the eclipse compiler. For this class, I had read something about online bug with the Eclase compiler (which uses this class generics) with generic , But this base class / interface has been re-implemented over and over in our code base and this is always a problem in this class. / P>

Does anyone know of an alternative solution to solve this problem, or better yet?

I can repeat this exception every time, so if any eclipse compiler developer reads it and it is known to the problem, please contact me to help keep an eye on this issue.

Update:

One of the many people implementing classes with this issue is Generic DAO where the normal interface is Defined: 

  Public Interface Generic DOA & lt; T, TLIT & gt;

This method is in the unsuccessful question: 

  Public T findsById (integer integer) throws APIException;

Try remodeling your code

It looks like you've got a DAO interface, and the interface's signature and impression is slightly different that the compiler does not implement the interface completely by the solid impact class. Eclipse may be out of par.

If this does not work, then see if eclipse allows you to navigate through the interface method for concrete implementation. If this can not happen, then this is a clue that the compiler is telling you.

Check your CLASSPATH. It may be that you think this transplant is being loaded by JVM.

Check the bug list if you think this is a problem with the compiler.

If you do not see a bug in the list, assume that you have problems many people use it; A bug that was seriously searched and fixed long ago.

Clear Jetties Deployment - War and all temporary files can be reconstructed and redistributed that the JT is placed on the older version of the class file, which explains why it works on the command line And when you work on the web.

Let's say you get the problem first, last, and always.

Update: Is there a way to switch JDK that uses Eclipse? Can you point to Sun JDK?

This is another reason that I hate eclipses.

Question: Are you implementing it?

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. 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...
