I want to install oracle weblogic server. I already downloaded it and it's fmw_12.1.3.0.0_wls.jar. In order to install it I'm instructed to run java -jar fmw_12.1.3.0.0_wls.jar. But when I run it I get
(...)X-Server access is denied on host
[Fatal Error] DISPLAY variable set incorrectly: :0
[Resolution] Verify that your DISPLAY environment variable is set correctly,
and that there is an X11 server on the system. If you are
running the Oracle Installer as a different user or on a different host,
you may need to use the xhost command to ensure that host/user
has permission to write to your display.

My system is: CentOS Linux release 7.6.1810 (Core) My java is: Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
I'm trying to perform this installation locally. I'm confused because every solution I came across assumed that I was logging via ssh or vnc server while I'm definitely not. What I tried:
set $JAVA_HOME to point to my jdk directory.
unset $ORACLE_HOME that was created for the database I have installed.
trying to set DISPLAY values to some other number than 0 (I know
its stupid but whatever).
reinstall java
I'm thinking if it might be the problem related with graphic drivers. Might it be that the defaults that were installed with X11 are somehow wrong? Or maybe centOS is not compatibile with this software? Should I maybe try oracle linux?
Add -Djava.awt.headless=true to your command line, e.g.
java -Djava.awt.headless=true -jar fmw_12.1.3.0.0_wls.jar
I solved my problem by using jdk 1.8 x64. This issue seemed to be caused by jdk 1.8 x86.
And yes, the problem was similar to yours. Give it a shot.

I stuck in install weblogic on my vm solaris. i try that
java -d64 -jar fmw_12.2.1.3.0_wls.jar
and i got an error
Checking monitor: must be configured to display at least 256 colors. DISPLAY environment variable not set. Failed <<<<
Any solution for these error?
This happens if you want to do an graphical install of the system without having a X11 running. The error message is quite normal for such an situation.
You could:
Not running the installer in the graphical mode by doing a silent install (please refer to https://docs.oracle.com/cd/E24329_01/doc.1211/e24492/silent.htm#WLSIG131 for information)
Install the nescessary package to have an X11 and stuff running in your VM with pkg install solaris-desktop. Then execute the java command again from the GUI . This obviously only works if you can get a the graphical output of the VM for example via VNC or other tools.
You could set the DISPLAY variable to an installed X11 implementation. For example i use Xquartz on my Apple notebook. Then configure DISPLAY and XAUTHORITY correctly. Or you could simply log into the Solaris system with ssh -X . I prefer the second one, as it does everything automatically.
I have installed XAMPP 7.2.10 on my Win 10 and other services like Apache and MySQL are working fine.
But the Tomcat service is not starting and is throwing an error as:
"Tomcat Started/Stopped with errors, return code: 1,
Make sure you have Java JDK or JRE installed and the required ports are free,
Check the "/xampp/tomcat/logs" folder for more information"
XAMPP Tomcat error image
I have installed Java JDK in "C:\Program Files\Java" and have set the environment variables path.
I have set the "JAVA_HOME" variable path as "C:\Program Files\Java\jdk-10.0.2"
Also, no other program is using the required ports.
When I run the "catalina_start.bat", I get error as:
"ERROR: The system was unable to find the specified registry key or value.
. [XAMPP]: Cannot find current JDK installation!
. [XAMPP]: Cannot set JAVA_HOME. Aborting ..."
What mistakes have I made here?
I had the same problem (XAMPP 7.3.0 / Windows Server 2016 / Java 11). I first checked the environment variables, the java installation - all seemed to be fine.
Sadly the XAMPP error message is not very meaningful, so i looked inside of tomcat installation. To my surprise XAMPP 7.3.0 uses a very old version of Apache Tomcat (7.0.56 from 2014!), that don’t work well with Java 9+. The reason is Tomcat 7.0.56 uses the "-Djava.endorsed.dirs" option, that is no longer supported in Java 9+. Up-to-date Tomcat versions have no problem with java 9+. To solve this you can just stay with Java 8 (if possible for you) or try to fix this on your own by modify Tomcat start-up: Go to your \xampp\tomcat\ folder and see this fix in Tomcat 7.0.73 doesn't work with java 9.
But i would recommend you to install a up-to-date version of tomcat and don’t use the XAMPP one (what i finally did) - at least until XAMPP updates there tomcat version .
I am getting following error while running /tmp/jprofiler8/bin/jpenable
No suitable Java Virtual Machine could be found on your system.
The version of the JVM must be at least 1.6 and at most 1.7.
Please define INSTALL4J_JAVA_HOME to point to a suitable JVM.
You can also try to delete the JVM cache file
I have also set INSTALL4J_JAVA_HOME to point to suitable JVM.
Java version on my machine is 1.4.2.
Can anyone please suggest what might be wrong or missing?
Unfortunately you did not mention details about your environment, so I don't know which Linux distribution you use.
There are some options though:
install a current JRE alongside the installer for JProfiler
As you can't install or update Java, you could provide a JRE in a kind of "portable application" setup. Simply unzip the server jre Oracle provides or (if you are not on an x64 architecture) unzip the jdk you also can download from Oracle.
But if the code you want to profile is limited to your pre-installed Java 1.4 you will run into another problem, because as far as I know Java 1.5 is the minimum JProfiler expects
use a different machine for profiling
Unless your code depends heavily on the environment you run it in you can even take a Windows 8.1 machine and profile the code there. Code that is slow is slow on any operating system. Or make use of a different Linux computer.
I want to use iReport on ubuntu 12.04. When I try to start it, it stands still and just gives me this error:
Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /tmp/jna4023560596826437553.tmp which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
How can I solve this problem ?
Edit: I tried: execstack -c /tmp/jna4023560596826437553.tmp but that didn't help.
This error seems more related to a JVM problem instead of jasper. Indeed, Java 7 on linux has a feature which blocks code written in C (or other languages like Ruby etc) and linked into Java (the so-called Java Native Interface - JNI) from halting the whole VM if it’s written badly or maliciously.
So, if you're using java version 1.7, getting back to 1.6 should do the trick. But if you want to keep this version, then try a clean uninstall and re-install of java:
Uninstall,
Install
Notice that if you're not running on 1.7 , it could be a compatibility problem. Try to match the right jars required for iReport to get it work on linux.
I'm using ubuntu and I did below,
Opened the ireport.conf
and uncomment jdkhome
and added java 7 paths (since my default is java 8)
jdkhome=/home/bhanuka/Apps/jdk-7u80-linux-x64/jdk1.7.0_80
I am Using Ubuntu 12.04 and i want to run OpenLaszlo 4.9.0 in my system. I have read many tutorial, e.g.
http://wiki.openlaszlo.org/Installing_OpenLaszlo#Installing_the_DevKit_on_Unix.2FLinux
that say that put server in JAVA_HOME but i do not know where is JAVA_HOME in Ubuntu 12.04.
I have OpenLaszlo also . But I do not know how to start server of OpenLaszlo and where to put it? or how many things required for it? please tell me. I have Red5 server,i have install java-7-openjdk.
Thanks in advance.
JAVA_HOME is an environment variable. It stores the path to java runtime environment (jre). You can have several JVMs installed on your system, of course. So JAVA_HOME defines the default one.
Setting this variable after installing Ubuntu package from the repository is a little tricky. It is discussed, for example, here:
Jenkins, specifying JAVA_HOME,
What is the correct target for the JAVA_HOME envrionment variable for a Linux OpenJDK Debian-based distribution?
OpenLaszlo is a Web-application that should be run under some application server (usually Apache TomCat or its derivatives such as IBM WebSphere Application Server Community Edition).
It is available on the off.site as a bundle that includes TomCat and also as a .war file (a servlet) that should be deployed under your application server.
In the 1st case you can extract an archive wherever you want (read carefully about file permissions). But at the moment the server starts it needs Java system files so JAVA_HOME should be already defined.
