I'm about to download and run Java8 with Netbeans, but there seems to be 2 different download files that's confusing me, they seems the same but with different sizes :
At https://netbeans.org/downloads/ "Java EE" is the one I want, it's size is 191M and the Java SE's size is 90M.
At http://www.oracle.com/technetwork/java/javase/downloads/jdk-netbeans-jsp-142931.html the size of "Windows x64" is 260M.
Why so much difference ?
I'm running Win7 64bit and I want the Java EE with Netbeans, how do I choose which one ?
I think the first link will allow you to fetch the NetBeans installer only whilst the second link will fetch you the installer and the JDK.
If you want both, go for the 2nd link.

I wanted to install J2ME and configure it with Netbeans. I followed two different tutorials word by word but somehow mine would give me many errors. After so much searching I realized that the JDK, Netbeans and J2ME must all be of the same level ie. all to be of x32 or all to be of x64. Now, how do I know what level is each of them at?
How do I know if NetBeans is x32 or x64, as well as JDK and J2ME?
I am using JDK 1.8, Netbeans 8.2, J2ME 3.4
For Java, you can do java -version, and it'll tell you what version you have.
I did a quick look around for the other two but couldn't find anything immediately. However, if you search something like "check bit version for Netbeans/J2ME" then you might get it.
Another way to figure out would be based on your OS. Depending on how new/old it is, it might require certain bit version. You probably installed the correct one (or you should uninstall and re-install the correct one based on their respective installation guide), so you should know what bit version when you first installed.
For Netbeans and J2ME just open them, then open the Task Manager. On the list of Apps, the version of the software is shown as shown below.
About JDK, Open your C Drive and look for the installation folder of your JDK. If it is installed in the Program File folder then it is x64, if it is in the Program File(x86) then it is x32.
I am brand new to computer programming for CIS 210 and it's off to terrible start. Downloaded JDK 9 and Netbeans 8.2. Netbeans won't let me open a new project or file. No error message or anything, almost as if I'm not clicking it. Screen remains blank as seen in the link below. It's driving me insane.
Blank Screen when I click on new project:
If you had Netbeans installation over Java 9 then Please note Netbeans does not work with Java 9. Proof: [https://forums.netbeans.org/topic68000.html][1]
The solution is for Windows, but the same logic applied in Linux too.
Solution1:
You have to edit netbeans.conf find to your java installation path. You can find netbeans.conf inside etc folder of Netbeans installation folder.
Make your netbeans.conf like below.
Eg, netbeans_jdkhome="C:\Program Files (x86)\Java\jdk1.8.0_144"
NetBeans 8.2 does not support Java 9. It just won't work.
The solution is to download the latest nightly build of NetBeans, which does support Java 9:
Normally you would go to the NetBeans download page and click the Development link in the top right corner of the screen.
However, I just tried that and it looks like their web page for downloading nightly builds is not working properly at the moment due to "...violates the following Content Security Policy directive..." errors. I've never seen that before.
A temporary workaround for that problem is to go directly to Index of /download/trunk/nightly/latest/bundles/ and select the download that is appropriate for your environment. You should be able to parse the file names to work out which one you want, depending on whether you need 32-bit or 64-bit, whether you are running on Mac OS or Linux or Windows, etc. (To be clear, ignore this bullet point if the Development link in the first bullet point above is working properly.)
Also note that you can safely install and run multiple versions of NetBeans concurrently: use version 8.2 for Java 8 development, and use the Development Version of NetBeans for Java 9 development.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Update:
The page for downloading Development Builds of NetBeans is working again, so go there, select your Platform from the droplist, and then click the appropriate Download button.
NetBeans with Java 9 is working fine for me using that approach.
NetBeans 9 would be supported version for Java 9, which was supposed to be released by Aug 2017
NetBeans 9 will be released from Apache Software Foundation as new
Apache project. NetBeans is being donated to ASG by Oracle. NetBeans
9 main theme will be to support this upcoming Java SE 9 release.
Of course, you can use NetBeans daily build, but there won't be guarantee of it's stability.
I've just installed Eclipse Helios 64bit but when i try to install Acceleo, te download seems endless and Eclipse seems blocked.
Is there someone that can help me?
Thank you
The very first install of anything in a new Eclipse tend to be extremely long (Eclipse usually contacts all of its available update sites and checks for update on every single installed plugin before doing anything).
Within a new Eclipse and with a lot of update sites available, the longest I've seen it take for a single install was about 10 minutes. You can usually check whether Eclipse is actually doing something by opening the "Progress" view (Window > Show View > Progress).
I am one of the member of the dev' team of Acceleo and I am always working on a 64bits Eclipse with a 64 bits virtual machine and there are no problems. If you are experiencing this problem it is because of a timeout of the update site. Right now, it is the release of the sixth milestone of all the Eclipse projects so the server tends to be overloaded. You can try it again or just wait a few hours. If you absolutely want Acceleo today, you can always download the zip version directly from here.
After updating to the latest (and now deprecated, sniff...) update of Apple's JDK, Eclipse does not show the source code for JDK classes anymore. It asks me to attach the source location file or folder. Where can I find that?
It seems that Java for Mac OS X 10.6 Update 3 does not include the sources anymore. There is a separate package "Java for Mac OS X 10.6 Update 3 Developer Package" now. See http://lookfirst.com/2010/10/how-to-fix-missing-source-for-latest.html
For each update from Apple, I write a new blog post with the updated symlinks. I noticed a lot of traffic on my blog from one of the answers, so I figured I might as well update things with the latest release.
I could write a simple shell script to do this for you, but that would require you to download a file. Seems simpler to just execute a few easy commands.
This is the latest one for update 5:

I am using Mac OS 10.8.5. I downloaded the java for Mac OS 10.7 and installed it. I found the src.jar file in
/Library/Java/JavaVirtualMachines/1.6.0_37-b06-434.jdk/Contents/Home/src.jar.
Then I
Opened eclipse(JUNO)
Eclipse > Prefereces > JAVA > Installed jre
Edit the java listed
In the jre system libraries section,
Expand the first one (i.e., classes.jar)
You can see that src is not attached
Double click that and provide the above location
That's it.
In my case the sources are in
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/src.jar
You might need to set this in the Eclipse preferences: Java - installed JREs. Select the 1.6 JVM and click edit. Now select classes.jar from the list of JRE system libraries, click source attachment and enter the path to your src.jar.
To all the guys who's been suffering from searching the source code here and there for hours but finally get nothing.
For Eclipse to attach(imperfectly available for 1.6):
jdk1.7.0_21_src_for_mac.zip
I'm using since today Eclipse on Windows 7 64bit. So eclipse is still pretty virgin, i just installed android plugin for it.
And I have many memory problems with it, which I didn't have with a worse computer however on 32-bit-Windows XP.
Did anybody make the same experience and what have you done to fix this out of memory errors?!
I read somewhere, that it's recommended to install beside JRE 64bit also the 32bit-version. Could it be true?
Thanks in advance,
Mur
Try to set higher Heap size using following options in your eclipse.ini file:
-Xms512m -Xmx1024m
Here I am setting max heap size as 1024 MB.
eclipse.ini file can be found in eclipse installation directory.
check other VM options here :

I guess, here is the answer:

I can confirm that this is a genuine problem due to an unknown incompatibility between OpenCV libraries and Windows 7 64-bit. I am not going to duplicate a huge amount of explanation why and what I am having trouble with so please follow my question raised in here http://answers.opencv.org/question/3996/cannot-do-anything-with-opencv-anymore-on-windows/
If you are running Windows 8 64-bit and you want to run Eclipse, follow these steps:
Unistall Java if you already have it.
Open Internet Explorer and go to the java official website.
Java Official Downloads Page
Click on the 64-bit version of Java to download, and install it.
Download Eclipse 64-bit version from eclipse website.
Eclipse Official Downloads Page
Click on the 64-bit version to download the zip file.
Extract all (you can rename it to simply "Eclipse" for convenience).
Run eclipse.exe inside the "Eclipse" folder and it should run.
Pick your Eclipse workspace and get some coding working. Hope this helps!
