I need a windows shell script which will redeploy my .ear file. I wrote one:
net stop "JBAS50SVC"
copy /y O:\TEMP\app.ear C:\jboss-4.2.3.GA\server\default\deploy\app.ear
net start "JBAS50SVC"
But the problem is that when I try to stop the JBoss service it does not fully unload itself (my suggestion), so when I start it there's no app deployed in JBoss.
You mentioned that JBoss becomes very slow when you use autoDeploy and keep the server running for a month or more. That's likely to be because your permanent generation memory is filling up over time. See this related question.
I think you'd be best served by using the autoDeploy feature as other suggest, and restarting the entire server periodically to clear out PermGen. There's several ways to track PermGen utilization; I add the following to JAVA_OPTS in run.conf:
-XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -XX:+PrintTenuringDistribution -Xloggc:$LOGDIR/gc.log
Typically to redeploy an application that is self-contained in an ear in jboss just requires replacing the ear. If there is more to the application (such as classes that have to go in the jboss lib directory) then it may require a restart.
In terms of how to restart it, it depends what you are using to start jboss as a service. Some service starters do not actually control the jvm after they start it, so restarting the service just starts a second instance. You can shutdown jboss with the shutdown script in the JBOSS_HOME/bin directory (shutdown.bat) and then deploy and restart the service. Be sure to pause when you do this, as the shutdown command will issue the shutdown request, the server may still be running.
You can just COPY/RENAME the EAR file to deploy directory. JBoss will automatically take care of re-deployment for you.
As mentioned earlier jboss automatically deploys everything you copy into the deploy directory by default.
If not, check if you are working on a vhost that doesnt autodeploy ear files.
<Host name="vhost2" autoDeploy="false" .... />
other than that, I feel like this is a totally different error due to the fact that jboss takes care of deployment for you. Please check the log files for startup errors of your application.
You might want to check the JBoss community wiki on this, there are undoubtedly easier and more reliable methods than a batch file.
Stopping the server should not undeploy the application - that wouldn't make much sense.

Before I explain the problem, I just want to point out that I am completely new to NetBeans and Tomcat and I am doing a school project. That being said, the problem is exactly what the title says. Here is the output when I try to run a simple Hello World jsp:
In-place deployment at
C:\Users\lostl\OneDrive\Documents\NetBeansProjects\Project3\build\web
Deployment is in progress...
deploy?config=file%3A%2FC%3A%2FUsers%2Flostl%2FAppData%2FLocal%2FTemp%2Fcontext7180600714574256491.xml&path=/Project3
FAIL - Failed to deploy application at context path [/Project3]
C:\Users\lostl\OneDrive\Documents\NetBeansProjects\Project3\nbproject\build-impl.xml:1058: The module has not been deployed.
See the server log for details.
BUILD FAILED (total time: 0 seconds)
I am using Apache NetBeans 11.2 and Tomcat 9 if it is relevant.
Here is what I tried:
I checked the server log and it displays absolutely nothing.
I tried setting the context path directly to Project3 (i.e. including the -C:/... before Project3) in the context.xml file under META-INF folder.
I tried restarting NetBeans and cleaning and building the project.
I tried running NetBeans under admin privileges.
I might seem like such an idiot for not knowing how to fix this since no one else seems to have this problem, but please help me out.
If you have installed the Apache Tomcat appart from Netbeans, maybe your apache service is already running and it conflicts with Netbeans. You may stop the apache service and then run the application in Netbeans.
Because Netbeans start the apache service in a diffent way, so you don´t need to install the aplication on apache´s folder.
Check out the Windows Services (Services App) and stop the Apache Tomcat if running, then from Netbeans menu select Run->Run Project. Netbean will start Tomcat and deploy your web app onto the Tomcat server.
I fixed it. All I had to do was restart my computer. I feel so dumb.
clean your project if clean project failed to delete some file then,
Just check there must be a java process running at background.
If you are using windows 10 then follow these steps
open command prompt and type below commands
tasklist | findstr java (hit enter now you can see a task list with pid number )
taskkill /F /PID "PID_OF_JAVA_PROCESS" (where PID_OF_JAVA_PROCESS--> task pid hit enter)
now run the project again
I faced this problem and found a solution. It is very simple. All you need to do is stop the Tomcat services or restart your computer and run your program.
We know that during Tomcat startup, it will deploy the .war files of its web applications. My question is after the deployment I need to run a command to modify a file inside WEB-INF/ of the web application which is generated after deployment, and I need to let Tomcat do this automatically for me, is this possible to achieve ? Something like post_run command after deployment.
I found that CustomEventHookListener can probably do this How to run script on Tomcat startup?, but this involves in making a new Java class, and I'm not allowed to do so. I have to figure out way to modify the existing Tomcat configs like server.xml or tomcat.conf in TOMCAT_HOME/conf to do so.
The main issue about not using a Event Hook Listener is that there's no reliable way to tell if the application is ready or not, as Catalina implements it's own lifecycle for each of their components (as seen in https://tomcat.apache.org/tomcat-8.5-doc/api/org/apache/catalina/Lifecycle.html).
Your best shot is to use tail or some external program infer the component's state, but AFAIK there's no way to implement listeners directly in the configuration files.
Trying to restart from command line weblogic server but it is picking up EAR file i deployed from Eclipse previously. Thought it was some kinda caching issue so opened/closed eclipse and cmd no help. Still picking up this EAR even when i delete it manually from the temp folder WL_User. Cant start weblogic from Eclipse as weblogic closes suddenly due to VM shutdown request and eclipse hangs on publishing state. Not sure why it does that too no error messages except BEA: VM requested Shutdown.
Very confusing how it is picking it up. Really want to understand why? Thanks for help in advance.
Your weblogic domain is in a bad state. Normally I would suggest removing a deployment by opening the weblogic admin console and navigating to Deployments and then deleting the problematic deployment. If you can't do that, try the following:
Navigate to <domain folder>/servers/<server causing problems>
Delete the tmp, data, cache, and logs folders
Restart your server.
Another option (you should only use if you are really stuck) is to edit the following file:
<domain folder>/config/config.xml
search for and remove your <app-deployment>
If it still doesn't work, you have other problems with your VM. Edit the question and add more info as necessary.
I was able to deploy my WAR the first time I placed it under domains/domain1/autodeploy dir. However, after making some changes and redeploying the WAR to the autodeploy dir, the changes were not picked up. I even deleted domains/domain1/applications/myapp (where myapp corresponds to the myapp.jar being deployed) but the WAR was not redeployed. The server was started and stopped via asadmin:
asadmin start-domain
asadmin stop-domain
What am I doing wrong so that the app does not get redeployed?
UPDATE: I tried manually (re)deploying (also using --force option) the WAR but got the following error in server.log:
[#|2013-03-17T20:47:36.177-0400|SEVERE|glassfish3.1.2|javax.enterprise.system.tools.admin.org.glassfish.deployment.admin|_ThreadID=72;_ThreadName=Thread-2;|Application with name myprojectname is already registered. Either specify that redeployment must be forced, or redeploy the application. Or if this is a new deployment, pick a different name|#]
I do not know how to unregister/undeploy an app that's been once deployed. I tried removing all the references to my app in domain.xml but it didn't work. This seems like a very basic bug in the software.
I know this was answered long ago, but in case anyone else gets here via google like I did, I have another possible answer ...
After encountering this same issue, I found the following ... the autodeploy/.autodeploystatus directory still had a file referencing the application I was trying to redeploy by copying the war into the autodeploy directory. I had to delete the file in the autodeploy/.autodeploystatus directory, then my application was deployed when the war was copied into the autodeploy directory.
Hope that helps.
NOTE: Apparently, it is obvious to others who use glassfish that you have to delete all this stuff from the hidden .autodeploystatus directory to get your re-deploys to work. Why is it obvious to them? We may never know.
You can undeploy via asadamin with:
asadmin undeploy yourapplication
You can also visit the glassfish admin console http://localhost:4848 and undeploy via the graphical interface (look at Applications).
In general the re-autodeployment should work, but I would recommend using the normal deploy method or an incremental redeployment by some IDE like NetBeans...
Exactly the same problem reappears for an application running to be deployed in Payara 5.2021.10 (perhaps for other recent versions > 5.193) within a docker container.
The problem happens every time the docker container restarts - the deployment fails with a message:
Application with name {applicationName} is already registered. Either
specify that redeployment must be forced, or redeploy the application.
Or if this is a new deployment, pick a different name
The problem can be fixed by a forced redeploy. Place something like this into a Dockerfile of the application image:
ENV DEPLOY_PROPS="--force=true"
This environment variable allows to set custom parameters to asadmin's deploy command. How exactly is it applied can be seen in the script that generates the deploy commands, that is being run from within the container's entrypoint.
Documentation says if you have a context file here:
$CATALINA_HOME/conf/Catalina/localhost/myapp.xml
it will NOT be replaced by a context file here:
mywebapp.war/META-INF/context.xml
It is written here: http://tomcat.apache.org/tomcat-6.0-doc/config/context.html
Only if a context file does not exist for the application in the $CATALINA_BASE/conf/[enginename]/[hostname]/, in an individual file at /META-INF/context.xml inside the application files.
But everytime I re-deploy the war it replaces this myapp.xml with the /META-INF/context.xml!
Why does it do it and how can I avoid it?
Thanx
Undeploy part of redeploy deletes app and the associated context.xml.
If you use maven tomcat plugin you can avoid deleting context.xml if you deploy your app with command like this:
mvn tomcat:deploy-only -Dmaven.tomcat.update=true
More info here: https://tomcat.apache.org/maven-plugin-2.0-beta-1/tomcat7-maven-plugin/deploy-only-mojo.html
You can use deploy-only with parameter mode to deploy the context.xml too.
The short answer:
Just make the TOMCATHOME/conf/Catalina/localhost dir read-only, and keep reading for more details:
For quick deployment mode (Eclipse dynamic web project, direct Tomcat
connection, etc.) on a local/non-shared Tomcat server you can just define your JDBC datasource (or any
other 'web resource') using the META-INF/context.xml file inside the
WAR file. Easy and fast in your local environment, but not suitable for staging, QA, or
production.
For build deployment mode (usually for staging, QA, or prod), JDBC
datasources and other 'web resources' details are defined by the
QA/production team, not the development team anymore. Therefore, they
must be specified in the Tomcat server, not inside the WAR file
anymore. In this case, specify them in the file
TOMCATHOME/conf/Catalina/localhost/CONTEXT.xml (change Catalina
by the engine, and localhost by the host, and CONTEXT by your context accordingly). However,
Tomcat will delete this file on each deployment. To prevent this
deletion, just make this dir read-only; in Linux you can type:
chmod a-w TOMCATHOME/conf/Catalina/localhost
Voila! Your welcome.
The long answer
For historical reasons Tomcat allows you to define web resources (JDBC datasources, and others) in four
different places (read four different files) in a very specific order of precedence, if you happen to define the same resource multiple times. The ones named in the
short answer above are the more suitable nowadays for each purpose, though you could still
use the others (nah... you probably don't want to). I'm not going to
discuss the other ones here unless someone asks for it.
On tomcat7, also woth autoDeploy=false the file will be deleted on undeploy. This is documented and not a bug (althought it avoids good automated deployments with server-side fixed configuration).
I found a workaround which solved the problem for me:
create a META-INF/context.xml file in your webapp that contains
on the Server create a second context "/config-context" in server.xml and put all your server-side configuration parameters there
on the application use context.getContext("/config-context").getInitParameter(...) to access the configuration there.
This allows a per-host configuration that is independent of the deployed war.
It should also be possible to add per-context configurations by adding contexts like "/config-context-MYPATH". In your app you can use the context path oth the app to calculate the context path of the config app.
According to the documentation (http://tomcat.apache.org/tomcat-8.0-doc/config/automatic-deployment.html#Deleted_files) upon redeploy tomcat detects the deletion (undeploy) of your application. So it will start a cleanup process deleting the directory and xml also. This is independent of auto deployment - so it will happen upon redeployment through manager and modification of war also. There are 3 exceptions:
global resources are never deleted
external resources are never deleted
if the WAR or DIR has been modified then the XML file is only deleted
if copyXML is true and deployXML is true
I don't know why, but copyXML="false" deployXML="false" won't help.
Secondly: Making the directory read only just makes tomcat throwing an exception and won't start.
You can try merging your $CATALINA_BASE/conf/Catalina/localhost/myapp-1.xml, $CATALINA_BASE/conf/Catalina/localhost/myapp-2.xml, etc files into $CATALINA_BASE/conf/context.xml (that works only if you make sure your application won't deploy its own context configuration, like myapp-1.xml)
If someone could tell what is that "external resources" that would generally solve the problem.
The general issue as described by the title is covered by Re-deploy from war without deleting context which is still an open issue at this time.
There is an acknowledged distinction between re-deploy which does not delete the context, and deploy after un-deploy where the un-deploy deletes the context. The documentation was out of date, and the manager GUI still does not support re-deploy.
Redeployment means two parts: undeployment and deployment.
Undeployment removes the conf/Catalina/yourhost/yourapp.xml because the
<Host name="localhost" appBase="webapps" unpackWARs="true"
autoDeploy="true"> <!-- means autoUndeploy too!!! -->
</Host>
Change the autoDeploy="false" and Tomcat has no order anymore to remove the conf/Catalina/yourhost/yourapp.xml.
There is an feature that allowes us to make those steps (undeploy/deploy) as one single step (redeploy) that do not remove the context.xml. This feature is available via the manager-text-interface, but the option is not available using the manager-html-interface. You might have to wait until the bug in tomcat is fixed. You can use the method described in this answer as an workaround.
