Deploying jenkins war file using java command

I am trying to deploy a jenkins war file. I executed the following command
java -jar jenkins.war
Below is the log file.

Can anyone tell me what does the command java-jar jenkins.war do?
WHere did it deploy my war file?
Which web server does it use and how does localhost:8080 point to jenkins application?

Q. Can anyone tell me what does the command java -jar jenkins.war do?
java -jar expects a jar file name, in this case, jenkins.war.
An executable Java program can be packaged in a JAR file, along with any libraries the program uses. Executable JAR files have the manifest specifying the entry point class with Main-Class: myPrograms.MyClass and an explicit Class-Path (and the -cp argument is ignored). Some operating systems can run these directly when clicked. The typical invocation is "java -jar foo.jar" from a command line
Reference: http://en.wikipedia.org/wiki/JAR_(file_format)
Q. Where did it deploy my war file?
In case it is a RHEL/CentOS installation, your war is deployed at /var/lib/jenkins
You can find out the location by reading the file /etc/init.d/jenkins. You will find a variable named JENKINS_CONFIG
JENKINS_CONFIG=/etc/sysconfig/jenkins
Q. Which web server does it use and how does localhost:8080 point to jenkins application?
In case it is a RHEL/CentOS installation, you will generally find the file here: /etc/sysconfig/jenkins. In this file, you define port on which Jenkins runs.

1) It executes the java arvhive jenkins.war (see http://docs.oracle.com/javase/7/docs/technotes/tools/windows/jar.html)
2) From the output you posted yourself:
Running from: C:\Sites\jenkins.war webroot: $user.home/.jenkins
the user.home variable may refer to your ~ directory on Linux, or your Document and Settings on windows. See http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html
3) From the output you posted yourself:
jetty-8.y.z-SNAPSHOT
INFO: Started SelectChannelConnector#0.0.0.0:8080
See http://www.eclipse.org/jetty/. This is a web server that register a listener on port 8080.

it uses the Manifest.mf inside, if you open the war, you would understand how it runs
The Main class uses winstone http://winstone.sourceforge.net/
I would recommend to use glassfish, jetty or tomcat - for better control on configuration
there is a bug open for that
https://issues.jenkins-ci.org/browse/JENKINS-18366
Also see various container notes

Tomcat is automatically shutting down

I have installed Tomcat 7 with Java 7 on a debian box. It has 512 MB of RAM. I run tomcat out of the box, I have installed nothing, and it is consistently shutting down by itself. I am not even browsing the Tomcat landing page.
As you can see, it is running perfectly normal and then all of a sudden it stops:
Jul 21, 2013 6:11:20 AM org.apache.coyote.AbstractProtocol start
INFO: Starting ProtocolHandler ["ajp-bio-8009"]
Jul 21, 2013 6:11:20 AM org.apache.catalina.startup.Catalina start

INFO: Pausing ProtocolHandler ["ajp-bio-8009"]
Jul 21, 2013 8:22:35 AM org.apache.catalina.core.StandardService stopInternal
It just mysteriously stops. What can it be? I know the Tomcat distribution and the Java distribution are good because I downloaded them from the Tomcat site and Oracle, and FTP'd them over to my server.
There are no other errors in any other tomcat log files. Is is a permissions thing? Memory issue? Appreciate your help.

I think a memory issue would show up in the log. I would simply reinstall Tomcat and check if it's still buggy.

Google App Engine not being accessed via localhost

I am using Mac OS X 10.7.4, app engine sdk 1.7.0, eclipse juno and Java as programming language. The problem is that App runs perfectly well when deployed on appspot but does not work on localhost. When run as web application on port 8888 or any other port (if change it from the configuration), the log represents server is running but when I hit the URL, nothing happens and after some time connection times out. When, debugged it gives the error: Cannot connect to VM. Logs from console for both run and debugged are shown below, kindly help me, I have searched all over the 'net but could not find the solution.
Log when Debugged:

Check the following:
1) If the application has actually started. Enter "ps ax | grep java" in terminal
2) If the application has bound to the port. Install nmap (not sure how to do it on mac) and run it with "nmap localhost". You will see a list of ports and protocols used. If you don't see 8888 with http then something is wrong.

Have you tried running it from the command line? It looks like you're trying to start it in the debugger as well.. no? Try running from the command line, make sure that works. Then try running it from eclipse with "Run" not "Debug" and make sure that works before trying the debugger. Appengine is a little bit particular...

App engine "hello world" not working (java)

i downloaded the google app engine plugin for eclipse and i opened a new web project.
but when i try to run this project (untouched) the eclipse say:
"The server is running at http://localhost:8888/"
so i opened the browser and i get 101 error
"The connection to localhost was interrupted."
what i did wrong?
here is what the console present:

(little details: i have windows vista, eclipse Helios Service Release 2.
i tried with jre6 or jre7 )

This can occur because of your 'Hosts File Configuration' or 'Proxy settings' or 'Anti-Virus software on your system' or if you are using web-debugging/http-logging tools like Fiddler or TCPMon. Correct the configuration if it is not properly set and try it again.

An incompatible version 1.1.12 of the APR based Apache Tomcat Native library is installed, while Tomcat requires version 1.1.17

How can I solve this problem?
When I open the localhost:8080/manager/html it shows the following error:
HTTP Status 404 - /manager/html
type Status report
message /manager/html
description The requested resource (/manager/html) is not available.
Apache Tomcat/7.0.6

The first error certainly sounds like a version mismatch. The APR library is a library linked in at runtime based on your path (which itself can be based on where you execute Tomcat from). It sounds like you have the APR library for Tomcat 6. It's possible that Eclipse is providing this APR library.
Tomcat ships with an APR library but in order to ease installation Tomcat doesn't automatically modify the path to point at the APR library. The Eclipse Tomcat integration may (I'm not sure on this one, haven't used the integration before) include the APR libraries to make it easier to use Tomcat.
Check and make sure that Eclipse isn't configured to use an earlier version of Tomcat and if it is, either upgrade Eclipse to Tomcat 7 or downgrade Tomcat to the version specified in Eclipse.
If you can't figure it out then you don't necessarily have to worry about it at the moment. Tomcat should work anyways without the APR libraries. The only benefit you will get from the APR libraries is increased performance and since this is probably the start of your project that doesn't have to be worked out right away.
The second issue, the /manager/ page, could be Tomcat configuration. Tomcat won't actually display the manager page (and it will give you that error) unless users have been configured with manager permissions.
Try going to just / (i.e. http://localhost:8080), that page should load regardless of user configuration.

In my case I had inadvertently installed the APR library when I install once Tomcat locally on my Linux using the package manager. On Debian/Ubuntu this installed the APR package for a different Tomcat version (the one bundled with your distribution) which caused this error.
After simply
sudo apt-get purge libtcnative-1
The error was gone.
