I am working on some JavaScript files, replace the file in tmp/vfs folder. It works fine only two or three times.during work on static content (HTML and JS files) I found, that wildfly seems to stop reloading the changed files after 2 or 3 changes.
I am working on a larger project, it takes 10 min for redeployment.
but I have found some possible solution :
hot deployment is fixed in 8.2 . ( but I have some restriction to update the server)
bypass redeployment. here (I tried this method, but issue is remained)
I recommend you to use exploded deployment and some configuration to enable hot-deployment for static resources, instead of replace the file in tmp/vfs folder. see my blog entry for detail: http://www.nailedtothex.org/roller/kyle/entry/exploded-deployment-for-wildfly-on

Here's what I know:
When uploading files given by users, we should put them in a folder
outside the deployment folder. Let me call it D:\uploads.
We should (somehow) add that folder (D:\uploads) as a web app context.
Here's what I did:
I upload my files to the folder D:\uploads.
I tried adding the web app context as it's mentionned here by adding the following row to TOMCAT_DIR/conf/server.xml:
<Context docBase="D:\uploads" path="/uploads"/>
But that doesn't have any effect. When consulting http://localhost:8080/uploads/file.png or http://localhost:8080/uploads I get a HTTP Status 404 error.
So what I want to know:
What did I do wrong ? How can I add my upload folder to Tomcat?
Is there any better approach when it comes to uploading files ?
Because I'm wondering what should I change if I want to deploy my
application to another server where there's no D:\uploads.
Change the docBase attribute. Use D:/uploads (with slash) instead of D:\uploads (with backslash).
When dealing with files in Java, you can safely use / (slash, not backslash) on all platforms.
Regarding the differences you mentioned in the comments when starting the Tomcat from the IDE and from bin/startup.bat: It's very likely when you start the Tomcat from the IDE, it is not using the same context.xml your Tomcat is using. Just review the Tomcat settings in the IDE.
How to store uploaded files is a common topic at Stack Overflow. Just look around and you'll get surprised in how this topic is popular.
If you aren't happy enough in storing your files in D:/uploads or you'll have other servers accessing the files, you could consider storing them in some location in your network. Depending on your requirements, you can have one dedicated server to store your files or just share the folder which contains the files in your current server. The right decision will always depend on your requirements.
We have an MVC 4 application that has 4 resource files. The default one (Resource.resx), one for Chinese and German (Resource.zn-CH.resx and Resource.de-DE.resx) and then one for a custom language (Resource.en-PI.resx (English-Pirate)) for testing purposes.
Every setting for all of the resource files is exactly the same:
Build Action: Embedded Resource
Copy to Output Directory: Copy Always
Custom Tool: PublicResXFileCodeGenerator
Custom Tool Namespace: Resources
Whenever the application is built locally, in the bin folder we get the folders de-DE, en-PI and zh-CN which all include a dll named (ProjectName).resources.dll.
The problem is whenever this application is deployed to our DEV server the folder for en-PI is ignored and not copied and we have to manually copy that folder over for the en-PI language to work.
We have a build definition that will build the necessary projects to a certain folder and do other things and then copy them over to our DEV server. Everything works perfectly fine for the other 2 languages (de-DE and zh-CN) but the en-PI folder doesn't show up in the bin folder. Is there some setting somewhere that is causing this resource file not to be deployed because it is a custom language?
The way all of these resource files were added followed this example http://odetocode.com/Blogs/scott/archive/2009/07/16/resource-files-and-asp-net-mvc-projects.aspx
Figured it out. Microsoft explains it here under the section Resource Naming Conventions. Because the language is a custom language and has a custom code it doesn't have a name that the common language runtime expects which is why it doesn't get deployed correctly.
I set up unit testing in Zend Studio last week, and it was working fine.. until suddenly after some refactoring, I got an error that the following file was not found in ZendPHPUnit.php:
/var/folders/Td/Tdnh++2KEdWAsk8Y0O4N0k+++TI/-Tmp-/zend.phpunit.UserMapperTest.php.2428213892936827201.php
The file path is stored in $_SERVER['ZEND_PHPUNIT_TESTS_LOCATION'] in ZendPHPUnit.php
I checked the folder and I found
zend.phpunit.UserrMapperTest.php.6031927106542896607.php (the number is different)
I was a little desperate so I made it work by forcing
$_SERVER['ZEND_PHPUNIT_TESTS_LOCATION'] = '/var/folders/Td/Tdnh++2KEdWAsk8Y0O4N0k+++TI/-Tmp-/zend.phpunit.UserMapperTest.php.6031927106542896607.php';
Eventually, after I worked with a few other test cases, the problem fixed itself. Now, I refactored some code again, and the problem is back. None of my testcases work.
Restarting the comp doesnt help, Project -> Clean doesnt help. I am on a mac running Snow Leopard.
Any insights on what is causing this?
Thanks!
The problem is that PHPUnit doesn't work with the files themselves but with copies of the files that it creates on the fly and stores on directories that are also created on the fly. These files are modified to include PHPUnit logic. This goes for the test files themselves as well as for the php.ini (which forces you to load extensions in the main php.ini file for the tests, since additional .ini files are ignored). Every time you run the tests these files will be re-created with a new unique name (original name plus unique identifier).
The best way that I've found to work around this issue is to create launch configurations for the tests and save them as .launch files in your project (right click -> run as -> create new PHPUnit config -> select "shared file" in the common tab). Once you have the launch configs you can just run this by opening on the editor and clicking the Run button. You will see that after every time you run them there will be a line like the following on each launch file that has changed (easy to see if the configs are in version control):
<mapEntry key="ZEND_PHPUNIT_TESTS_LOCATION" value="/var/folders/my/ph9spb0s45z5_11l9tqw256r0000gn/T/DefaultWorkspace.phpunit.AssignmentRequestControllerDateCriteriaTest.php.4951739174960507380.php"/>
I usually just commit this change together with whatever other changes I've been working on at that time.
It's still kind of annoying that the file changes and thus the launch config, but at least in this way your tests will always run and you don't have to worry about having to re-run the manually, or clean the project, or anything like that.
I have a problem that, after a lot of reading and research, seems like tomcat is running another instance of itself and thus serving an old version of my updated app (or somehow has cached an older version of my webapp somewhere only serves that.)
I work on the app in eclipse on a windows machine and deploy it on a Linux server as a ROOT app (Renaming the war file to a ROOT.war).
What I'd like to know is if there's a way to locate the older version that tomcat is serving by getting tomcat to log an output of the context root of the servlet that's serving the older version of the app.
As it stands it the moment any files created by the updated app get created in the right directory but because the app instances are different it can't access the files shortly after they're created.
Any help/hints would be welcomed
To answer the question in the title, let your code basically do the following:
System.out.println(getServletContext().getRealPath("/"));
To solve the problem described in the question, shutdown Tomcat and delete everything in its /work directory, delete the expanded WAR in /webapps and remove the /Catalina subdirectory of /conf directory (if any) and then restart.
Sometimes we have huge amount of JAR files in jboss/server/web/tmp/vfs-nested.tmp directory.
For example today this directory contained over 350k jar files.
But on other hosts there are only 2 jar files in this directory.
What can be the root cause of this problem?
We use JBoss 5.1
UPDATE:
I found following information in release notes for JBoss 5.1.0.GA:
JBoss VFS provides a set of different
switches to control it's internal
behavior. JBoss AS sets
jboss.vfs.forceCopy=true by default.
To see all the provided VFS flags
check out the code of the
VFSUtils.java class.
So I do not understand what should I set?
Should I set -Djboss.vfs.forceNoCopy=true or -Djboss.vfs.forceCopy=false?
Or should I set both of them?
UPDATE 1:
I have read entire thread http://community.jboss.org/thread/2148?start=0&tstart=0
and now I am not shure that I should change either jboss.vfs.forceCopy or jboss.vfs.forceNoCopy.
According to this thread I will have OutOfMemory error instead of huge amount of files in tmp dir.
From here: http://sourceforge.net/project/shownotes.php?release_id=575410
"Excessive nestedjarNNN.tmp files in the tmp directory. The VFS unwraps nested jars by extracting the nested jar into a tmp file in the java tmp directory. This can result in a large number of files that fill up the tmp directory. You can disable this behavior by setting -Djboss.vfs.forceNoCopy=true on command line used to start jboss. This will be enabled by default in a future release, JBAS-4389."
jskaggz has a good answer. In addition, I have this in the beginning of my run.bat file:
rmdir /s /q c:\apps\jboss-5.1.0.ga\server\default\tmp
rmdir /s /q c:\apps\jboss-5.1.0.ga\server\default\work
rmdir /s /q c:\apps\jboss-5.1.0.ga\server\default\log
mkdir c:\apps\jboss-5.1.0.ga\server\default\tmp
mkdir c:\apps\jboss-5.1.0.ga\server\default\work
mkdir c:\apps\jboss-5.1.0.ga\server\default\log
echo --- Cleared temp folders ---
I've had problems with old copies of classes hanging around, so this seems to help.
We have solved this problem by exploded deployment ( works for war and ear) as described in jboss documentation http://docs.jboss.org/jbossas/docs/Administration_And_Configuration_Guide/5/html/ch03s01.html
That's way vfs is not used.
I had the same issue described above in production and resolved it with the following solution.
Added java options
-Djboss.vfs.cache=org.jboss.virtual.plugins.cache.IterableTimedVFSCache
-Djboss.vfs.cache.TimedPolicyCaching.lifetime=1440
My setup also defines additional deployment directories so I needed to add these additional directories to vfs.xml file located in $JBOSS_SERVER_HOME/conf/bootstrap/ in order to see the benefit.
The lifetime setting I think is in minutes so I set it to a day as I have a scheduled restart of the server overnight.
Prior to finding this solution I had also tried using -Djboss.vfs.forceNoCopy=true and -Djboss.vfs.forceCopy=false
This appeared to work but I noticed the application ran a lot slower - presumably because these settings turn vfs caching off.
My Jboss version is jboss-5.1.0.GA
and my application runs in a cluster on production.
Found a lot others having the same problem running in cluster (or farm) environments.
https://issues.jboss.org/browse/JBAS-7126 desribes to solve the problem having a farm directory as deployment directory.
I had the same problem using a 2nd deploy directory.
The jar files out of my applications coming from this 2nd deploy directory got copied until the disk was full.
Tried adding the 2nd deploy directory the same way as at https://issues.jboss.org/browse/JBAS-7126 described for the farm directory.
It works well!
We were facing the same issue and were able to circumvent the issue by using a farm directory as deployment directory.
After putting that process in place we were facing one more issue due to the nature of our DEV environment ( We have clustered environment and we have many developers deploying on the shared DEV environment ) of not getting a consistent results while we were deploying the EARs and WARs that way .We circumvented the issue by making sure that the EARs and JARs that are being deployed are TOUCHED (http://en.wikipedia.org/wiki/Touch_(Unix) ) on the servers to make sure that inconsistencies are avoided .
