Jenkins fails to start up and empty plugins directory

I am new to jenkins, I upgraded a couple of plugins(don't remember which), after that I when I try java -jar jenkins.war I end up getting the following error.
jenkins.InitReactorRunner$1 onTaskFailed
SEVERE: Failed Loading global config
java.io.IOException: Unable to read /home/.jenkins/config.xml
I went through several links which address this issue, but no luck yet. In this link which I found https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=764711 it says some plugins are missing, and surprisingly, my /home/.jenkins/plugins/ is empty!!!
How do I restore the necessary plugins from my command line?
I am using CentOS release 6.8 (Final)
Thank you :)

I had encountered this issue somedays back,however after restarting jenkins service solved the issue.
The best you can do now is rename your config file. This way jenkins will load with the default startup.

Boxfuse run command does not find file in application.properties

I have a Spring Boot application that has application.properties file in resource folder. That file also includes:
server.ssl.key-store=classpath:certificate.jks .
When running boxfuse on my local machine (boxfuse run myJar.jar) everything is ok (Payload started in 01:02.631s -> https://127.0.0.1:8448) but when I try to do boxfuse run -env=dev myJar:1.0 the application fails to start due to vb-1d056c6c => java.io.FileNotFoundException: /app/certificate.jks (No such file or directory) . I do not think this is a problem with my app, but with Boxfuse. What should I do?

The problem was that I already had an image with version 1.1 so Boxfuse created a new version number. I was not paying atenttion to the log so when I ran the deploy to AWS command, I was actually deploying the old version. Got to pay attention to logs

Activiti Explorer - Request resource is not available

I have big problem to run activiti-explorer when i try access: http://localhost:8080/activiti-explorer/ tomcat shows me HTTP Status 404 - The requested resource is not available. I'm really don't have any idea why that dosen't work. Can you help me?
This what have I done on my PC:
I'm using 5.19.0 version of activiti-explorer
7.0.63 tomcat
JDK 1.8.0.77 (i think there is no point to downgrade java to previous versions (<=1.7) becouse my main application using this version)
I'm sure I have correctly configured environment variables (JAVA_HOME,JRE_HOME,PATH,CATALINA_HOME)
I configured data base connection (db.properties, context.xml) in activiti-explorer.war and i moved this file to tomcat/webapps
I don't have any errors about activiti during tomcat start

Check if activiti explorer is deployed to tomcat in manager.
http://{host}:{port}/manager/html
More info in https://tomcat.apache.org/tomcat-7.0-doc/manager-howto.html

Check the catalina.out log. There will be something in there that leads you to the solution.

Check Admin Console (cmd that runs behind) after hitting the link. most recent exception occurred will be displayed there.

java 8 with Glassfish 4.1 Artifact HelloWorld:war exploded: Server is not connected. Deploy is not available

I create a simple java web service project in intellij idea and configured the glassfish 4.1 server. and just run the application. output window shows the following messages

Attempting to start domain1.... Please look at the server log for more details.....
[2015-06-10 01:35:00,667] Artifact HelloWorld:war exploded: Server is not connected. Deploy is not available.
Detected server admin port: 4848
Detected server http port: 8080
server is running fine. but webservice is not deployed. can anyone help me.
I use java 8. intellij 14, glassfish 4.1 and windows 8.1
I followed following posts, but none of these are helps me.
post one , post two , post 03, post 04
I spend last two day to find an answer, please help me.

Check your Facets and your Artifacts are all right. Facets must have web deployment description and Web Resource description, the absolute path is all right.
Check the Artifact output directory, make directories:
WEB-INF/class/{your compile output},
the resource directory for example web app directory content.
I think the IntelliJ use ant as it's deployment tools, then you can image how it work, just denote the path the project need

Unable to start server in Eclipse Gallileo IDE with WAS7

Server not starting in Eclipse Gallileo IDE with WAS7.
I run the server from outside of Eclipse but I want to start it from within the eclipse
Below are the details of my Workspace configurations :
Eclipse Java EE IDE for Web Developers.
WAS 7.0
An alert is coming saying "Cannot connect to VM socket closed".
I got the following exception in console :
JVMSHRC154E Escape character g not valid for cache name
<JIT: FullSpeedDebug: ignoring countString>
<JIT: FullSpeedDebug: ignoring countString>
JVMJ9VM015W Initialization error for library j9shr24(13): JVMJ9VM009E J9VMDllMain failed

Per the JVMSHRC154E, it appears that somehow -Xshareclasses:name=...%g... is being added to your server JVM command line. I do not know why there would be a difference between Eclipse and the command-line (perhaps a product issue that should be reported to IBM), but you could try working around the issue by adding -Xshareclasses:nonfatal to your server's generic JVM arguments.

IBM has released development tools for WebSphere Application Server (WAS).
You can download it from eclipse market place.
There are tools for the WAS7 and up. (IBM Information page)
You probably need WAS 7 Tools - marketplace page.
The short instruction is:
In the eclipse click Help->Eclipse Market Place->Search WebSphere Application Server Tools.

Inside eclipse installation folder go to \plugins.....\cdcla\eclipse\launch\simple.
Open the file websphere70.properties.
You will see the following content and remove the
"_%g"
part and save it
shareclasses=webspherev70_%g,groupAccess,nonfatal
