Any idea why this is happening? I am using OSX Maverick and Eclipse.
I have no Add method used in my program and I don't see the reason it's nagging about it.
You could try to restart the Eclipse. I had this problem too and it works.
"The debugger issue is a restriction of the Eclipse hot-swap JPDA/JVM mechanism. Presently there is a limitation to how much a class may be modified and still be replaceable through the JPDA. My understanding is that can the shape of a class may not be modified, i.e., add/remove fields or methods. The "may be out of sync" warning indicates the change to a class within Eclipse has not been replaced in the server's JVM. To resolve this problem you must restart your server. In the near future we are planning to add an application RELOAD feature that we believe will workaround this problem. " ------myEclipseide.com

I think that JVM run by Eclipse is not the same as the JVM running your Java application.

I am developer who is using xTend. The docs for this kind of programming language are introduced at this link:
https://www.eclipse.org/xtend/documentation/
When I used Eclipse Photon version to develop my product. I ran into the issue related to debugging.
AFAIK, xTend code will always be intermediately compiled to java code first.
The issue description as below:
The debugger can hit breakpoints if they are toggled in java code.
But, when I toggle breakpoints in xTend code, the debugger doesn't hit the breakpoints any longer.
I tried some times to refresh my Eclipse workspace (delete old one / create new one), even used other version of Eclipse. But, still didn't solve the issue.
Who had already run into this situation, could you share your idea or solution on this ?
I have resolved the problem.
This happened because the configuration not adequate.
If you have same situation to me,
please consider to check all below Eclipse debugger's configurations.
I was working this afternoon in my project without problems. Before come home I did a commit to my svn to continues it in home, but now when I try to run it shows a code error that hadn't shown before. The Following code it's supposed to initiate new scene using controllers and passing parameters. Error:
Someone knows what is happening? If you say "The code is wrong" it's not possible cause I was using the exactily same code in my work.
Detail, in the afternoon i was using Mac OS and now I'm using Windows. And IDE is Netbeans in booth places
My problem was not about code, actually the code is right.
The problem ocurred because my Netbeans was pointing to a old version of JavaFX. The way to fix it was to uninstall everything about java from my computer and after reinstall with the newer versions of JDK, JavaFx and Netbeans.
Cast your loaders to their appropriate types. For the first cast it to the Login Controller and for the second cast it to the MainViewController.
NetBeans only see's an abstract Object being returned, even though what is actually being returned is a little more specific. I'm not sure why this happened when you moved from one platform to the next (I assume you have the same version and everything), but some compliers will catch this as an error and others will not. Technically there is no error, just questionable results.
I am in a very very upset situation. My program worked 100% fine when it is in netbeans, but when I build it it has some issues. That is, in my program, there is an one interface and 10 implementation classes. Program calls correct correct implementation class based on how the user save the file (eg: if user save it as game.yellow, it will call "YellowImpl.java", if saved as game.red, then "RedImpl.java" likewise).
But when it is built, it is calling everything fine, instead YellowImpl!! Which means, if the user saves it as game.red, it will call "RedImpl" correctly and same to all other implementations instead YellowImpl. When the user save the file as game.yellow, the program do nothing!!! But this is not happening when it is inside the netbeans! I tried clean and build too, still not good! What is causing this ? Please help!
However, I am unable to provide the code, because it has lot of codings
PS: I am using some libs too
It's difficult to understand exactly what issue you are having with your explaination and no code. However I assume you are having issue with implementation naming conventions.
Perhaps the below link can help.
Java Interfaces/Implementation naming convention
I am agree with #Rhys: it is hard to understand what happens in your application. Just let me give you an advice: do not think (even for 1 second) that there is a bug in java compiler, JVM etc. It is definitely your bug.
How to find it? I suggest you to use remote debugging.
Run your application outside IDE (NetBeans in your case) with enabled remote debugger, connect to it with net beans and debug your application. I believe you will fined the problem within minutes.
How to enable remote debugging? Add the following long string to your java execution command line:
-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
If something happens in very beginning of your program execution use suspend=y.
Now connect to this application from NetBeans. It is simple, just configure it to port 8000 according to the configuration of your application.
That's it. Good luck.
Thanks a lot for the replies guys. However, I managed to find the issue. That was a simple, capital case!! I have a package called "kolor" and all the implementations are inside that. In my "YelloImpl" class, I have mentioned the package as "Kolor" (Note that "K" is capital). It was fine in netbeans, but outside it wasn't. After clearing this out, everything went fine. Thanks all for the replies again.
So, nothing has changed with my setup over the past week. I have recently upgraded to Lion, but I have run this application several times since I have done that.
Today, I click the "Run Main Project" arrow in NetBeans 6.8, and I get a dialog box I have never seen before...
I have absolutely no idea what to do. I can find no reference to this error in Google.
Steps I have taken:
Reviewed the logs (nothing unusual up to the point where NetBeans freaks out.
Reverted to a backup Netbeans installation (no change in behavior)
Attempted to change the username/login information to the administrative Glassfish panel (no change in behavior)
Removed the .netbeans directory from my home, and restored to a known good offsite backup.
I have absolutely no idea what "8228 8228 8228" means.
One thing important to note is that Glassfish is running and the creds that I have supplied to NetBeans do work. I can log into the running Glassfish admin panel with them.
Any suggestions at all?
Leaving this here for anyone who happens to run into the same problem.
I would wager that this affects all versions of NetBeans.
I am not entirely sure what caused the original issue, but it appears that NetBeans attempted to "auto-discover" a proxy that I had installed on my system. (GlimmerBlocker, for blocking ads, among other things)
When it did this, Glimmerblocker did not report its IP address correctly (or NetBeans interpreted it incorrectly), resulting in something that looked like:
127.0.0.1
127.0.0.1:8228
8228
8228
Well, needless to say, when the Java NumberFormatter got a hold of that, it didn't like it one bit.
Setting NetBeans to "No Proxy" in it's settings, and restoring from backup again (to undo all the troubleshooting damage I had done) took care of the problem.
Again, leaving this only in the hopes that it helps at least one other problem who may run into something similar.
I am building an application in Java using Netbeans IDE. I am trying to debug some errors in my code. But even when I modify messages passed in the log statements, I do not see a corresponding change in the logged messages. This implies that when execute the code, it probably runs an older version of code & prints the old version of log messages as well.
What is the cause of this error ? & how should I rectify this ?
Thanks for helping..
I had that same problem...closing and reopening netbeans fixed it for me...
By saving the code. I assume, you are have compile-on-save enabled. If not then you have to build it before running it.
Yes you need to enable build-on-save, otherwise GlassFish wouldn't be able to show you the changes, because the new changes have never been deployed. Sometimes, deploying on save bothers a lot. So, what I do is, I don't enable build-on-save and work with tests and thereby run my tests to see the result of the change. When everything seems fine, then I build the app and deploy it on the server for further verifications.
Compile on save must be set.
See the properties of your project.
(Right click, select properties, then select compile).
Another possibility is that you have to redeploy
your project. In such a case I would recommend to
take a look at jRebel.
