I recently downloaded eclipse Kepler and JDK 1.7 to my Debian-machine and setup eclipse to be in
/usr/local/bin/eclipse
and the JDK to
/usr/share/
When I work in terminal, I can start it just fine.
Now, I wanted to add a link to GNOME 3 applications menu. So I cat one of the files, and changed it accordingly. When I click on the icon in the applications-menu I am displayed with
"either a JDK or JRE must be present in eclipse/jre. java was not found in PATH".
Can I go around putting the JRE into the folder? How can I adjust the PATH when I use the applications-menu?
Add your eclipse.ini file:
--launcher.GTK_version

I am using Eclipse Luna (Java EE IDE). I need to add jdk because my project is been converted to maven. Whenever , I install maven console gives an error
No compiler is provided in this environment. Perhaps you are running
on a JRE rather than a JDK?
So i used Preference>installed jre's. However , when i am trying to change JRE to JDK by using Search button in Installed jre's. It shows me only JRE not JDK. Although , i am providing JDK path.
In short , I need to change my environment to JDK.
Thanks. Please help me out
In the preferences screen, remove the JRE listed there.
Add > Standard VM + Next > Directory + navigate to the jre directory inside jdk folder and Finish
If done right then JRE Home should look like "C:\Program Files\Java\jdk1.8.0_05\jre", NOT "C:\Program Files\Java\jre8"
Next, make sure you have the new JRE System Library listed under the Libraries tab in Java build path and in the Java Compiler (right click on project > properties) you define enable project specifics and set Compiler compliance level to the version you want.
Hope it helps.
Just open: Window-> Preferences ->Installed JREs and press SEARCH. Chose a folder and eclips find all avaliable jre and sdk.
I have JDK 1.6, JRE6 and JRE7 (64-bit & 32-bit) installed in my PC.
I am using Netbeans 7.3 BETA 2 and it is using JDK 6 and JRE 6.
I want to change it to JRE7. How can i achieve this ?
I have checked in Stackoverflow itself and found that we have to change the netbeans.conf file content for the netbeans_jdkhome value to the path of new Java path.
In another stackoverflow question, I found How to specify which JRE to use in Netbeans?.
But, in this also, I am not able to find how to get this resolved. Can anybody help on this ?
My installation path is as follows,
JDK6 path - C:\Program Files (x86)\Java\jdk1.6.0_31
JRE6 path - C:\Program Files (x86)\Java\jre6
JRE7 path - C:\Program Files (x86)\Java\jre7 (32-bit)
JRE7 path - C:\Program Files\Java\jre7 (64-bit)
Thanks in advance.
Goto Tools -> Platforms
Click "Add Platform", browse to the location where the JDK you want to add is installed....
Click on the JDK you want to add and select "Finish"
Updating projects
You can change the platform that projects use, by right clicking the project node and selecting properties and selecting Libraries. Here you change the platform that the project will use to build the classes with.
You can also change the source/binary format (version) which Netbeans is expecting to use. For example, you use JDK 7, but build/develop for Java 6
Changing the JDK that Netbeans itself uses to run
Goto {install/location/of/Netbeans}/etc and open the netbeans.conf.
There is a property called netbeans_jdkhome (it was towards the end of my file). You change this to what ever JDK you want Netbeans to be launched with
I copy the eclipse-jcde-0.2 into eclipse'plugin folder ,but the plugins in eclipse doesn't work, Do I still lack of something necessary such as FEATURES folder and how can I get the features ?
OS:windows
Eclipse version :3.2.
It is working fine for me.
I have followed exact instructions from the link eclipse-jcde
Only changes I have did is I have used Eclipse 3.5 instead of eclipse 3.2
For Installation in Eclipse 3.5 follow the below steps.
After downloading Eclipse 3.5, inside eclipse folder create plugins folder (if already not present.)
Paste all the jar files from the downloaded zip file (eclipse-jcde-0.2.zip\plugins folder) to plugins folder (there are 8 jars)
Start the eclipse in -clean mode.
To Start eclipse in clean mode : On the eclipse folder right click and open command prompt, then issue the command eclipse -clean.
Now follow the instruction to set the path for java-card-dev-kit-home as mentioned in the above link.
I am able to create java card project and applet and even start the JCWDE simulator as well.
I am having two JRE / SDK in my development environment, however it was necessary in my situation to set JAVA_HOME to 1.4.2, this is causing my eclipse IDE to stop running as it required 1.6 and above.
May i know how i can modify eclipse ini or environment home to use my other 1.6 installation?
Please try the eclipse.ini entry above the varargs (the following two lines must be two lines in the eclipse.ini file)
-vm
C:\Java\JDK\1.5\bin\javaw.exe
Find the JVM
Right click the project in Package Explorer -> Configure Build Path
Add Library -> JRE System Library
Set JRE system library to JDK
Verify JDK is the reference library
From the menu in the top.. Proceed as follows--
Project-->Properties--> Java Build Path--> Libraries--> JRE System Library.
Now click Edit . Select Alternate JRE. Click Installed JRE. Provide path to your other JDK. Then FINISH.
That's it.
I've instaled the Java for Developer package provided from Apple for 10.7 and java apps are running fine
but eclipse cannot find the JDK root path and I cant either.
Anybody any ideas?
You can download the 10.7 Lion JDK from http://connect.apple.com.
Sign in and click the java section on the right.
The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.
At the time of writing the JDK ended up here:
/Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
Open up eclipse preferences and go to Java --> Installed JREs page
Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location
At the time of writing Search is not aware of the new JDK location; we we will need to click on the Add button
From the Add JRE wizard choose "MacOS X VM" for the JRE Type
For the JRE Definition Page we need to fill in the following:
JRE Home: /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
The other fields will now auto fill, with the default JRE name being "Home".
You can quickly correct this to something more meaningful:
JRE name: System JDK
Finish the wizard and return to the Installed JREs page
Choose "System JDK" from the list
You can now develop normally with:
javadocs correctly shown for base classes
source code correctly shown when debugging
On newer versions of OS X you should find ALL JREs (and JDKs) under
/Library/Java/JavaVirtualMachines/
/System/Library/Java/JavaVirtualMachines/
the old path
/System/Library/Frameworks/JavaVM.framework/
has been deprecated.
Here is the official deprecation note:
http://developer.apple.com/library/mac/#releasenotes/Java/JavaSnowLeopardUpdate3LeopardUpdate8RN/NewandNoteworthy/NewandNoteworthy.html#//apple_ref/doc/uid/TP40010380-CH4-SW1
I have just ran into the same problem after updating. The JRE that is downloaded by OSX Lion is missing JavaRuntimeSupport.jar which will work but can wreck havoc on a lot of things. If you've updated, and you had a working JDK/JRE installed prior to that, do the following in Eclipse:
1) Project > Properties > Java Build Path > Select broken JRE/JDK > Edit
2) Select "Alternate JRE"
3) Click "Installed JREs..."
4) In the window that opens, click "Search..."
If all goes well, it will find your older JRE/JDK. Mine was in this location:
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
For Mountain Lion, Apple's java is up to 1.6.0_35-b10-428.jdk as of today.
It is indeed located under /Library/Java/JavaVirtualMachines .
You just download
"Java for OS X 2012-005 Developer Package" (Sept 6, 2012)
from
http://connect.apple.com/
In my view, Apple's naming is at least a bit confusing; why "-005" - is this the fifth version, or the fifth of five installers one needs?
And then run the installer; then follow the above steps inside Eclipse.
You can download jdk6 here http://support.apple.com/kb/DL1573
Wish it helps
