we use ElasticSearch in a distributed environment. I tried to update the JDK from 1.6.x to 1.7.0_51. But when I do that the ElasticSearch Service cannot be started anymore.
Environment:
Win Server 2008
ElasticSearch 0.90
JDK 1.7.0_51
JAVA_HOME is set and functional (otherwise my JBoss would mention the missing JDK)
When I use the batch, ElasticSearch starts normally. Has anyone encountered the same problem?
JAVA_Home was ignored, so I tried to install a JRE
And this was the fix. I don't know why the JDK ignored.

I am trying to install weblogic on one of my local environment.
But when trying to install the weblogic application, it said java.exe or javaw.exe has stopped working
and the program crashes. Any idea on how to fix above issue?
Below is the java path in Weblogic folder
C:\bea\jdk131_14\bin
Thanks
Weblogic server does not support Java 13.
You must use Java 8 (or 7) with WebLogic server 12c.
I am newbie to web services. i am trying to generate stubs using Apache CFX on eclipse. when i try to add CFX in preferences using Windows >> Preference eclipse gives error "Invalid Type Name". i tried to change the JRE from JDK 6 to 7. change the versions of CFX but still problem persists.
Please help in resolve the problem
I found the solution. The problem because of multiple java version installed on my machine and CFX found two different versions of JAXB. I uninstalled java 7 from my machine and then it worked with java 6.
I am attempting to start Apache Geronimo using the command:
./bin/geronimo run
When I do this, it spins for a minute, issues the message "Main not found" and exits.
This article suggests that it is a system resource issue:
http://apache-geronimo.328035.n3.nabble.com/jira-Created-GERONIMO-5551-Failing-to-start-the-server-with-the-error-quot-Main-not-found-quot-td1324013.html
I have tried it on both an Amazon EC2 box (running Linux), and an Azure A1 box (running Windows Server), and I have tried the "Full Profile Release" and "Web Profile Release" of Geronimo, all with no change.
I'm at a complete loss as to what I could try. I am led to believe that the EC2 box, at the very least, should have the muscle to run Geronimo.
Any suggestions would be welcome.
Version 3 of Apache Geronimo is designed to run on JRE 1.7 instead of JRE 1.8. As stated in the other answers, the issue was caused by Geronimo being run on JRE 1.7 instead of 1.8.
You are not limited to JRE 1.7 and earlier in order to run Geronimo though. Therefore, all you have to do is to rename or copy the property jre-1.7 in the file etc/config.properties in your installation to jre-1.8. Afterwards, you should be able to run Geronimo without an error.
This has a huge benefit, since now you will be able to run programs on Geronimo that use Java 8 features.
It turns out that the issue is that I had the wrong version of the JDK installed. I had installed the most recent version (8), but Geronimo apparently won't work with that. When I instead installed version 6, everything worked fine.
I was getting the same error with Java 8. I tried the latest version of Java SE 7 and that resolved the problem. So I wouldn't use Java 6, since it is and has been out of support for awhile now (read: security issue).
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.
This is post is in continuation of the below post in Worklight:

As suggested by Idan in the last comment, there is no JAVA_HOME environment variable set as of now on the Linux machine.
The problem is even if I set the JAVA_HOME environment variable, I am not sure which jdk path to add as there are multiple instances present on the Linux machine.
Please suggest me as to which jdk path to pick.
Thanks
You can find the Worklight system requirements depending on what version you are using, and what set up you need. However, if I remember correctly, I think you are cool using Oracle JDK 1.7 or IBM JDK 1.6.
