JBoss EAP 6 - How to deploy huge exploded folder - deployment

We run JBoss 6 in standalone mode. We do have a folder (content.war/) in deployments that contains a symlink to a different folder (let's call it docs). Symlinking is enabled in jboss-web.xml with <symbolic-linking-enabled>true</symbolic-linking-enabled>. Our scenario is to use this to serve static files via this app context.
We do deploy the folder using touch content.war.dodeploy. It all works fine when the docs folder contains just few files. When the docs folder points to actual folder that has around 30GB the deployment seems to be stuck (the folder is not deployed and no other deployment works afterwards).
I believe that JBoss tries to somehow traverse or scan the whole folder. Is it possible to somehow disable this behaviour?

One workaround seems to do the trick. I can deploy an empty exploded war folder and once it is deployed I create the symlink to the huge folder.
Disadvantage: When JBoss is restarted it gets stuck again. I'd need to remove the link and create it again after deployment.

Another option is to use welcome-content that JBoss uses to serve static content. I can remove the original welcome-content folder and create a symlink to my folder instead.
ln ‐sv /home/mypath/my-static-content ${JBOSS_HOME}/welcome‐content
Disadvantage: This doesn't allow you to use any symlinks inside your folder or subfolders.

how to download war files from wildfly 8

Wildfly 8:
Where are the deployed war files located on the server file system?
How do I download them? I tried using the JBoss CLI as well as the Web Interface.
Found the war files to be located here. In this directory I found several subdirectories. The war files were all named content and did not have an extension. I could figure out what they were based on file size and timestamp.
wildfly location\standalone\data\content
You want the files 'after' they have been deployed? This generally isn't a good idea as it isn't guaranteed to be exactly the same as the source archive.
The standard location for the deployment archives is ./standalone/deployments/ although this can be changed in the configuration.
After an archive is deployed you can see the exact location of there the deployed archive came from in the configuration, it will be written to the bottom of the xml file.
There is a download button to download the .war
in the management console localhost:9990
click the view button near your war
on top you will find a download icon
I found it in the %WILDFLY_HOME%\standalone\temp\ directory. If it is not present there then you can perform a search in all the subdirectories of the wildfly.

Deploying GWT in localhost and see that webpage

I am a new user in GWT and I want to deploy one of existed samples in my localhost. I could run the example by eclipse and get the result. But I need to deploy that example in my localhost (IIS). How can I do this?
Copy the contents of your project's war directory to your server's document root. You could create a folder there, mproject for example. Then load your project on a web browser: localhost/mproject to view.
Go into your project's war directory For EX:
C:\workspace\HelloWorld\war
Select all the files & folders available inside war directory.
Zip all the selected files & folders in a file called HelloWorld.zip.
Rename HelloWorld.zip to HelloWorld.war.
Deploy it to the server

Tomcat6 not applying changes from deployed WAR file

Assume app myapp that is under Tomcat's webapps. It is deployed there via myapp.war, which is dropped in webapps. The most usual form of deployment.
However, after I make changes to a WAR constituent (e.g. a JSP) and redeploy the WAR (making sure the change made it into the WAR by expanding the archive after it was dropped in webapps), I start the server and the changes do not get deployed to the myapp final directory. If I delete the dir altogether, the change makes it in but but when I am just updating.
Does anybody have any idea why this bug is ocurring and what I need to do to remedy this deployment nuissance?
Into your project directory within webapp inter into the module directory (rename-to='module_name') and delete all files but don't delete directories

Can someone explain what GlassFish does with deployed directories

I have an exploded directory that I am editing in eclipse (created via setting location to directory location when creating New Project, deployed directory already existed). When I deploy this directory from the command line, it does not seem to save it locally (anywhere within glassfish\domain_
If I create a Java EE application in eclipse from scratch and deploy it from Eclipse Run -> on server, it copies it to glassfish\domains\domain1\eclipseapps
Is there a way to have GlassFish save deployed directories locally without using the GlassFish plugin magic?
Short Answer: No.
The whole point of directory deployment is speed and development convenience.
You tell GlassFish to not copy any files at all but to, instead, use the files already laid out on disk.
If you want to run from a copy of your app then just deploy the archive (war/rar/ear/jar) file.

Deploy war file with modifiable properties files

I am building a web service and am packaging it into a war file for deployment. Right now all of my config files (.properties and .xml) are being packaged into my .war file. This isn't going to work as some of these files will need to be modified for each individual installation. I know that some servlet containers will leave the .war files intact which would mean the config files would never be easily modified. My question is this: what is the best practice for deploying a .war file with these external config files? I'm thinking that the config files will need to be shipped separate from the .war file and placed into a directory that is in the classpath. Is there a default directory setup like this in Tomcat that these files can just be dropped into and my web service will be able to find without much trouble?
Maybe I shouldn't be using a war file for this setup? Maybe I should just be providing a zip file (with the same contents as the war file) and the deployment will simply be to extract the zip into the webapps directory?
I do not know any default directory in Tomcat to store configuration, my
attempts to solve the same issue have been :
1 - Move configuration to the DB and provide scripts or webpages to modify values.
2 - Have a script to deploy the war. The script would merge configuration from a user directory into web.xml or other deployed config files.
3 - Have webapps look first in a user directory for configuration and
if not found then look for configuration files deployed by the war.
Least favorite is 3 - it require all webapps to check two places for configuration and
you end up with two different xml files on the server with different values and it is not always clear which one is used.
Next favorite is 2 - the webapps can be written without knowledge of multiple config files, but you run into issue when someone does a deploy from Tomcat manager instead of using your script.
Favorite is 1. This just works in most cases. Problem is when you don't have a DB or
want to configure how you connect to the DB.
If having the file visible from all webapps is not an issue, you could put it $CATALINA_HOME/lib.
One solution is to modify property file after deployment of war file is to use ServletContext.getRealpath() method to get the real path means path of file in the server where it is deployed and then modify that file it will modify file in container only not the original file. So you need to backup it if it is important modification for you. So by this you do not need to redeploy war file as it is already modifying file from deployed container.
This solution can edit a file that is in webpages folder also from the java class.
If you want more description or how to do it then let me know i have did it.
