How do i configure WebLogic 8.1 to use a specific JRE / JDK on my development machine. I realized that it is using hot spot and i would like to change it to run on JRockit.
You need to change the JAVA_VENDOR setting in the setDomainEnv.sh/.cmd file (depending whether you are running a Linux or Windows box).
Adding/changing the following lines to the start of your setDomainEnv file should work:
set JAVA_VENDOR=BEA
set BEA_JAVA_HOME=(path to your jrockit installation, e.g. c:\BEA\jrockit)
Now you should start the server. You can monitor, in the console (stdout), the indication about which Java version is being used:
starting weblogic with Java version:
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
BEA JRockit(R) (build R27.6.0-50_o-100423-1.6.0_05-20080626-2105-windows-ia32, compiled mode)
It is also possible to do it during the configuration wizard, when you are adding a domain, under the Java SDK Selections tab.

I need to add my installed Java 11 version to the project settings, because of this error (Error:java: invalid source release: 11).
When i go to project structure -> Project settings -> Project there it just shows Java 1.8.
When i try to add "java-11-openjdk-amd64" it fails with the reason "The selected directory points to a JRE, not a JDK.".
java -version
openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.4+11)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.4+11, mixed mode)
The java application is available in the Java Runtime Environment (JRE). The fact that java is available in version 11 does not necessarily mean that the Java Development Kit (JDK) is also installed for version 11. However, IntelliJ needs the JDK which includes tools like the compiler javac.
In order to use Java 11 in IntelliJ, you need to install the Java 11 JDK.
For example on Ubuntu you can do that by executing:
sudo apt install openjdk-11-jdk
I just updated to IntelliJ 2019.2 but I can't find the new Services tool window (described here). Neither View - Tool Windows - Services nor Alt + 8 is showing it. What am I missing?
Additional Information:
IntelliJ IDEA 2019.2 (Ultimate Edition)
Build #IU-192.5728.98, built on July 23, 2019
Runtime version: 11.0.3+12-b304.10 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Windows 7 6.1
The tool window automatically pops up when you run something related to a managed service (for example, run a Docker container). However, in case of run/debug configurations, you have to specify which types you want to be available in the Services tool window. For this, go to Run | Edit Configurations, select Templates, and add necessary configuration types to the Configurations available in Services list: https://blog.jetbrains.com/idea/2019/08/services-tool-window-one-place-to-rule-them-all/
I am stuck with the following problem regarding Intellij IDEA.
I had installed the following java version:
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode, sharing)
on my Win7 PC and using Intellij IDEA v14.1.3.
After some time, I have upgraded my jdk and now I have installed the following:
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) Client VM (build 24.71-b01, mixed mode, sharing)
I have consequently changed all the references to point to the new jdk in system variables and in Intellij in Project structure ...
Everything seemed to work fine (when I run a program from Intellij I see that the command java is invoked from the right path).
The problem is that for some reasons, when I open the integrated terminal in Intellij and write java -version the result is the old version (1.7.0_51).
I realized this because of some issues of the old version of java I face when I run my unit tests that should have been resolved in the new version.
Have anybody any idea how to solve this?
Thank you in advance!
I would not only update the java version, but completely delete it from the machine. Obviously, you have not removed all the references to the old java, as your problem statements describes.
Maybe the Java Uninstall tool might be helpful for this? Then make a clean new installation.
Configuration: Eclipse (Juno) 4.2.2
IBM Worklight version: 6.2.0.01
Java version:
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)
JDK: jdk1.7.0_71.jdk
Java Compiler: 1.7
My worklight studio was previously working and suddenly stops working after I had to force quit my eclipse. Even after reinstallation of the plugins, the error still recurs.
Here's a screenshot of the initial error log before 'Worklight server failed to start' and 'Failed to deploy application in the worklight server'. Any help to fix this issue will be deeply appreciated. Worklight studio issues like this is starting to get frustrating.
I uninstalled java from my mac. Reinstalled Java (JDK & JRE), new Eclipse (Juno 4.2.2) -> Then installed IBM Worklight Studio plugin. Figured it was the problem with Java as it was throwing the java exception 'unable to read the manifest'. Probably there was some issue after updating to Yosemite.
I had the same problem. You need to set correct IP for Worklight server. It doesn't work with "localhost" or "*".
It looks Java EE got corrupted somehow,
So as suggested the best approach would be to use a fresh Eclipse instance with a new plug-in installation and a new workspace as well. This way it makes sure everything is fresh and new.
I'm using Ti Studio on Win7, and my project builds and works when I have my Android plugged in via USB and I run using "Android Device".
However, when I try to buid it for distribution I get:
[ERROR] Program launch failed. Unable to locate Java VM. Please set JAVA_HOME environment variable.
I have looked at this thread which describes a similar problem, and verified that JAVA_HOME is set:
+>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.6.0_29
Also, in Ti Studio I have verified that Preferences->Studio->Platforms->Android has the "Android SDK Home" set to the path where Android SDK is installed.
Can anyone guide me on what else I need to do to fix this?
Thanks!
UPDATE FOR ANAND
+>javac -version
javac 1.6.0_29
+>java -version
java version "1.7.0_01"
Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
Java HotSpot(TM) 64-Bit Server VM (build 21.1-b02, mixed mode)
Did you read System Requirements?
From Documentation:
For Windows, the 32-bit version of Java JDK is required regardless of
whether Titanium is running on a 32-bit or 64-bit system.
Try to install additional 32bit version of Java (without removing the 64bit) and set the system variable.
You may refer this answer.
Hope it helped you
Configure environment variables as mentioned here and JDK must be 32 bit
