I am following this tutorial to deploy my web_test app; when I enter http://0.0.0.0:8080/web_test-0.1.0-SNAPSHOT-standalone/ on the browser I see a "hello world" displayed . . . but that's not what I have in core.clj file! I have "Hello World; it works!"
I did everything over, I created a new .war file, and I ran Jetty again with
$ java -jar start.jar
but I see the same wrong "hello world"
What am I doing wrong?
As I was posting this related question came up, so do I need to change the configure file to redeploy? How?
That tutorial looks pretty far out of date.
The easiest way to test your ring app is to use lein ring server, which will start an embedded jetty (usually port 3000), and then automatically reload code as you make changes to your Clojure files. It's very lightweight and quite nice.
This tutorial is more up to date. http://zaiste.net/2013/05/getting_started_with_clojure_web_apps/

Is there a full download I can use which downloads leiningen and all related stuff in one go? I am not able to change the proxy settings on my local network, and this is the error I get:
"DownloadFile" with "2" argument(s): "The remote server returned an error: (407) Proxy Authentication Required."
Update
You need to download the Leiningen standalone jar and then point LEIN_JAR to it:
set LEIN_JAR=full path to leiningen standalone jar
For me - setting the proxies didn't work (and downloading the jar was unsatisfactory)
I got:
the wget binary, and
the wget dependencies
and put them on my PATH - ie h:\util contains:
wget.exe
libssl32.dll
libintl3.dll
libiconv2.dll
libeay32.dll
(where H:\util was already on my path. )
and then got a new terminal cmd.exe - and then lein self-install worked.
Assumptions:
Downloading the jar was unsatisfactory because the point of lein is to be a dependency manager (like maven). You need to keep downloading stuff. If you manually download the first jar - then when you add some more jar dependencies to your project you'll have to manually download those as well. Might as well chuck out lein and go back to doing things on the Java classpath.
In my view - in a windows environment proxy settings should be automatically detected. Lein can't do this (yet) - but the wget version I downloaded could. So you solve the problem of needing to explicitly specify the proxy. (In addition - manually setting the proxy just didn't work for me)
This should help:

You should work on your googling skills ;)
I want to post this as a comment to #hawkeye, but I dont have enough reputation. This work for me only when I set environment variable.

I am very new to plone. I have a project folder in eclipse. I have imported it from the cvs project. I have zope as server and I start zope with ./bin/instance restart. When I make changes in my folder, I cannot see the changes in the development website. I can't seem to find what is happening. I even restarted zope after making changes in python. Can anyone help me with this?
Make sure you start your Zope server with bin/instance fg, most likely the name of the script if you used the Plone universal installer buildout.
To see changes in python code you'll either need to restart the server (CTRL-C then start again) or use something like plone.reload to request a reload of changed code.
When starting your server with the fg command, it is automatically running in debug mode and any templates, resources and skin items are reloaded automatically. Start the server with console or start and it'll run in production mode and templates and such are loaded from disk only once.
See the Plone.org documentation on buildout for more information.
The bin/instance command has a built-in help command, try:
bin/instance help
for a list of supported commands or run:
bin/instance help console
to get help on a specific command; the above example will print the help on the console command.
Am using jettyrunner for executing my war files.I am using command java -jar jetty runner ex.war.But am running this jetty server from my java application by executing this commands from java.My problem is at first time its working good,but the second time if i am again executing another war file with the same code its executing the older war.i have found the reason that the older jetty server is keep on running.How could i stop this server from java in order to start the jetty server for another war.
One option should be:
http://wiki.eclipse.org/Jetty/Howto/Secure_Termination
Another would be to use the ShutdownHandler:
http://git.eclipse.org/c/jetty/org.eclipse.jetty.project.git/tree/jetty-server/src/main/java/org/eclipse/jetty/server/handler/ShutdownHandler.java
Or don't use the jetty-runner directly like that from java code and just write a small embedded usage:
http://wiki.eclipse.org/Jetty/Tutorial/Embedding_Jetty
Turned out, jetty-runner.jar doesn't have a feature to stop existing jetty process ran with stop-port and stop-key.
I found the answer in https://github.com/jetty-project/jetty-documentation/blob/master/src/docbkx/administration/runner/jetty-runner.xml
Then, to stop jetty from a different terminal, you need to
supply the same port and key information. For this you'll either
need a local installation of jetty, the jetty-maven-plugin jetty-ant plugin, or write a custom class
Fortunately, I was implementing gradle build, so jetty-ant satisfied my needs.
I'm a Jetty newb, but it's making life hell. First there was an Eclipse problem I described in another question. Rather than waste time on it, I decided to just run Jetty from the console. I started off importing a sample Tapestry project and was able to run it fine... the project is on the Tapestry page and is called tutorial1
I began work on my own project then and began introducing new functionality to it. At some point it stopped working. I tried backtracking my project to get it to a working state but every time I requested the home page it would just hang. At this point I still thought it was my fault, though I did think a more graceful error message would have been nice than the it attempting to load for a minute followed by a server timeout error.
I then shutdown jetty and attempted to load up the imported sample project using mvn jetty:run in my tutorial1 project directory. it doesn't work either! When I try going to localhost:8080/tutorial1 or the URL of my project the jetty console does show any output, almost as if it's not receiving the request.
I rebooted my entire machine but that doesn't help. I am not familiar with jetty architecture and am unsure if there is a way I can purge all my files from the jetty web application directory.
Any ideas?
Cliffs Notes:
Downloaded Tapestry Archetype project with maven.
Executed jetty from the command line using mvn jetty:run
Started new project
Executed jetty from the command line using mvn jetty:run
Modified new project
Error occurred, attempted fix and restarted Jetty (Ctrl + C, followed by mvn jetty:run)
Jetty restarted, but did not seem to handle requests for any pages
Tried starting jetty from Archetype project, experienced the same problem
If your project didn't deploy correctly, jetty won't serve any pages (they will either return 404 or some error in the 500s).
Look at the log folder and check if it is getting correctly deployed.
How can I configure a Tapestry5 project to run standalone (via java -jar) with embedded Jetty?
I'm looking for a short "recipe" regarding Tapestry5, Jetty, configuration of servlets/ handlers/ whatever is needed to connect the dots...
I've seen a few dots: How to Create an Executable War, Configuring Tapestry (ref Tapestry as servlet filter)
Edit: I'm thinking about a standalone running webapp due to server circumstances. It doesn't have to be embedded Jetty, but I can't rely on a stable appserver. Still looking for a recipe, though, so I don't spend much time on dead ends...
Also, I'd like for Jenkins (Hudson) to be able to stop and start the server automatically when deploying updates - I don't know if that influences what I can do with Jetty, f.ex.
Well, i believe this is a general "how to run a war question". Assuming you indeed have a war, you can use jetty or winstone to "run" it - see :
http://winstone.sourceforge.net
and
http://www.enavigo.com/2008/08/29/deploying-a-web-application-to-jetty/
In the first case, you can directly do
java -jar winstone.jar --warfile=<warfile>
https://github.com/ccordenier/tapestry5-hotel-booking/
<-- Check its maven build
http://tapestry.zones.apache.org:8180/tapestry5-hotel-booking/signin
I did some digging, and this is the short recipe I basically ended up following:
Start with the Maven Jetty plugin as configured in the pom.xml of the Tapestry 5 archetype
Add the stopKey and stopPort attribute to Maven Jetty plugin configuration
Let Jenkins CI run maven target jetty:stop and then clean install
Let Jenkins run shell script mvn jetty:run &
Voila - my Java app is up and running with automatically updated code, without any appserver.
