I'm working on a web application that is packaged as an EAR with two WARs in it which are two apps accessed using different URLs within the app.
There is a lot of common jars and due to the size of the EAR there has been a task on backlog for ages to reduce this size by moving the common jars to the EAR.
After some reading online on the structure to use, I've updated the gradle scripts at EAR and WAR level to do this and I now have an EAR with the following structure:
EAR
APP-INF
lib
all the common jars
META-INF
application.xml
MANIFEST.MF
weblogic-application.xml
war1.war
war2.war
The manifest of each war has been updated with the Class-Path attribute which has the path to the jars in the APP-INF/lib directory.
Getting this far was easy.
The problem is that I cannot deploy the EAR with my weblogic server. I'm getting error on startup related to the jars that have been moved so its like weblogic cannot find them.
Maybe the stuff I've read is wrong and the layout I have is all wrong so I'm just looking for a steer. I'd be more familiar with tomcat than weblogic so I'm not confident that what I have is correct in terms of the format when putting common jars in the EAR rather than the WARs.
Note: I'm running weblogic server through IntelliJ if that makes a difference.

I have a resource bundle with language properties. If the local language is French, it loads french texts or else default English. My program works okay when using Intellij but when I create the jar file and try to run it by doing java -jar myapp.jar then it crashes and shows error.

This is how I use the resource bundle
ResourceBundle resBundle = ResourceBundle.getBundle("lng", Locale.getDefault());
if (Locale.getDefault().getLanguage().equals("fr")) {
usernameLabel.setText(resBundle.getString("username"));
passwordLabel.setText(resBundle.getString("password"));
loginButton.setText(resBundle.getString("login"));
exitButton.setText(resBundle.getString("exit"));
}
My program structure looks like this.
EDIT: This is how I created the jar executable file.
File -> Project Structure -> Artifacts -> click on the plus sign (+) -> Jar -> From modules with dependencies.
Select the main class and OK. Followed by Clicking on the + sign and adding all files from the javafx bin folder to the File ( all the dll files).
Go to Build -> Build artifacts -> Build.
The bundle name you are looking up is "lng", but your the files in your bundle have prefixes of "Lng".
The case of the resource file name and the bundle lookup string should match.
If you are using a Windows system, the lookup on the file name is case-insensitive when using the file protocol to access the unpackaged resources.
But, when packaged in a jar, the lookup of the resources using the jar protocol is case sensitive.
Which explains why you can find the resources when not packaged in a jar, and why the lookup fails after jar packaging.
In addition to the issue with the jar packaging, relying on case insensitive file names also means that the project would fail if used on an OS with a case sensitive file system, like a Mac or Linux system.

I can successfully load jxbrowser in the non-OSGi environment, as well as in OSGi environment when resources are already extracted.
Is there any way to make jxbrowser successfully extracts the resources from the jar?
It is looking like you don't have a correct OSGI bundle for JxBrowser. As far as I know jxbrowser supports OSGI bundle distribution, you can simply install it into your OSGI container.
Alternatively you can create your own bundle with which is only exports JxBrowser public API, but contains JxBrowser libraries you need. You can automate it with Felix bundle plugin for example http://felix.apache.org/documentation/subprojects/apache-felix-maven-bundle-plugin-bnd.html
In order to make such a bundle working you will need to initialize an temporary browser instance (just create a browser component) inside bundle activator. So that chromium binaries will be extracted when bundle is installed in your OSGi container.
My Project build in Intellij with maven and compiles fine and deployed in tomcat nothing problem in local system (window)
But after deployed war file in linux system. I tried to access method that throws, exception class not found.

I can see there are libraries in WAR excluded directory in linux (where I deployed)
My Code

What might be the problem please say some solution
I'm trying to run a RecommenderJob on amazon EMR. I have a jar called SmartJukebox.jar (not runnable) and it contains a class main.TrackRecommander (and that's it).
I created a job flow with the jar:
s3n://smartjukebox/SmartJukebox.jar
and args:
main.TrackRecommander --input s3n://smartjukebox/ratings.csv --output s3n://smartjukebox/output --usersFile s3n://smartjukebox/user.txt.
The class TrackRecommander uses the class RecommenderJob.
I run the job flow and i get this in the error log -

now i see that the JVM can't find RecommenderJob and i didn't put RecommenderJob in my jar. I thought EMR would have mahout jars built in, but i can't find anything about that.
what is the solution here?
Thanks.
You're problem is exactly what you say: "I didn't put RecommenderJob in my jar." Unless you put those classes in your JAR, of course it can't be found. Why would EMR have this built in? Add the Mahout ".job" file classes to your JAR first.
You will need to create a job jar which contains all the classes required by the code to run which includes the mahout classes too.
Take a look at
https://github.com/tdunning/MiA
Check how to create a job jar using maven assembly plugin in pom.xml and the job.xml in the src/main/resources directory.
IF you exclude the hadoop classes then you can run it on any hadoop instance.
I'm having trouble running a custom jar on Elastic Map-Reduce
I'm using jdk1.6.0_26, Hadoop 0.20.205, and compiling with Eclipse on my computer and everything works perfectly fine
for example if I ran the following on my computer it would be successful
hadoop jar MaxTemperature.jar input/temperature.txt output
I specified the jar as the following on AWS
s3n://chrishadoop/MaxTemperature.jar
and I specified the arguments as
s3n://chrishadoop/input/temperature.txt s3n://chrishadoop/output
I did not specify the main class because I pointed to it in the manifest
Here is the jar I'm using, I will make it public for a little while
https://s3.amazonaws.com/chrishadoop/MaxTemperature.jar
Here is the error I'm getting

There is a version of Jackson which is installed as part of the AMI, and I'm guessing you're bundling a different version of Jackson? The error seems to be happening in the support code which makes "enable debugging" work.
