I want to read my console output logs, and I know that they are stored into "log" folder under the file catalina.out, but it doesn't exists! I have tried in different ways with no results. I don't know how to figure it out, I just want to see my java outputs logs
If the catalina.out is deleted after tomcat is stopped, it will create a new catalina.out once tomcat starts again and it is totally safe.
But if you remove the catalina.out while tomcat is running, it will keep on logging to catalina.out which is removed already (reference of the file is hold by the tomcat) hence the space will not be released. So you will need to restart the tomcat sever to release the space. It is not recommended.
Start/ Run Tomcat server and it should create catalina.out file without any error.
Following are the multiple ways of running tomcat. Just indicated in detail so this would help someone in need.
./catalina.sh run
Passing "run" argument for catalina.sh --> starts the Tomcat in the foreground and displays the running logs in the same console. when the console terminal is closed it will terminate the tomcat.
./catalina.sh start
Passing "start" argument for catalina.sh --> starts the Tomcat in the background. Since in background no issues closing down the terminal. The logs need to be viewed as below: tail -f $CATALINA_HOME/logs/catalina.out
./startup.sh
The last way is firing the startup.sh to start your Tomcat server. If you Vi the script you can see it calls catalina.sh script passing start as the argument. This will be running in background as well.
Now check your tomcat log directory and you should find the catalina.out
From catalina.sh , it says :
# CATALINA_OUT (Optional) Full path to a file where stdout and stderr
# will be redirected.
# Default is $CATALINA_BASE/logs/catalina.out
So , look at your script that is used to start Tomcat to find out what the value of the environment variable CATALINA_OUT.
go to the bin folder of tomcat and run below script
./catalina.sh start
now catalina.out exist in logs folder
When we upgraded our Beanstalks to Tomcat 8.5 with Corretto 11 running on 64bit Amazon Linux 2, catalina.out no longer existed and not all logs were present in catalina.date.log. We re-established the catalina.out with the following file dropped into /etc/rsyslog.d/catalina.conf
$umask 0000
$FileCreateMode 0644
template(name="Tomcat" type="string" string="%msg%\n") {
property(name="msg")
}
if $programname == 'tomcat' then {
action(type="omfile" file="/var/log/tomcat/catalina.out" template="Tomcat")
}
if $programname == 'server' then {
action(type="omfile" file="/var/log/tomcat/catalina.out" template="Tomcat")
}
you will want to restart rsyslog afterwards.
service rsyslog restart

I was having issues installing and running tomcat today and had to do a lot of research to get it running. I'm putting my solution here in case anyone runs into the same problem.
When I opened the url localhost:8080 in my browser, I would get a "refused to connect" error. I checked if the port 8080 was being used by another service, and it was not.
I then noticed that tomcat wasn't starting. I tried opening it through services but that didn't work either. Later services showed tomcat stuck in the "starting" status. I then tried to run tomcat through the command prompt with these commands.
cd: c:/filepathToTomcat/bin
bin>startup`
That gave me this error
jre_home variable undefined and java_home variable undefined
Using the solution to
https://stackoverflow.com/questions/18468681/tomcat-6-java-home
I created a setenv.bat file in the tomcat bin and set the java_home variable.
My setenv.bat file contained
#ECHO OFF
set "JAVA_HOME=C:\Program Files\Java\jdk-19"
set "JRE_HOME="
Tomcat still wouldn't run. A solution on
https://stackoverflow.com/questions/5398654/tomcat-not-starting
suggested using "catalina.bat run" on the command prompt instead of startup.
This showed that tomcat wouldn't start because it couldn't get the java virtual machine to run. I then uninstalled and reinstalled java and tomcat started working for me.
I used Java version 19 and tomcat 10.1.5 on a windows 11.
so I've manually installed tomcat version 9.0.10 and the newest java JDK.
I've correctly added the manager-gui and admin-gui users. i have went into the server.xml files and found that all the ports were correct.. (connecting to default port 8080) I had to do []# unset CATALINA_HOME or else it wouldn't let me start tomcat so I did and it started but when I went to the browser and typed in the localhost:8080 it didn't show, it only says firefox could not establish connection with server localhost:8080 so I went into logs to see if there were any errors and sure enough there was an error like so: /usr/local/tomcat/apache-tomcat-9.0.10/bin/catalina.sh: line 464: /usr/bin/Java/jdk-10.0.2/bin/bin/java does not exist.. and its probably right why would there be /bin/bin/ like that in a directory.. so i went into the catalina.sh file copied what it had inside into a blank file in documents and went to line 464 (txt editor numbered the lines for me) and what i found was this line at 464: eval $_NOHUP "\"$_RUNJAVA" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS %CATALINA_OPTS\
but I have no idea what to do about it.. i think i might have a path problem or could be a port problem but I don't think so... I've installed apache and it works great in the browser with localhost.. could that affect the tomcat access maybe?
anyway, id really appreciate any help I can get.. I'm very new to this by the way. I'm sorry, I couldn't copy and paste from my virtual machine so I had to type it. im on centos 7.
I think you are looking for tomcat deployment page where you can manage your artifact. If that is correct
First thing you need to check is that whether your installation contains tomcat manager application.
You can verify this by looking in to this path ("apache-tomcat-9.0.10\webapps\manager") If this path is absent you may have to reinstall your tomcat.
Try downloading the zip from the below path and start the server.
If you are trying to deploy your custom application you may have to provide the context path for accessing you application. Also you can verify the deployment by looking in to the above path. For eg: if you are trying to deploy test.war then a folder named test will appear in the webapp folder.
Hope this helps.
I am running Ubuntu 16.04 and I need to install and run Restcomm JSS7 stack as a JBoss AS Service.
I followed this video tutorial to install JBoss AS 7. Then I set the JBOSS_HOME environment variable to installation directory of JBoss AS 7. As a result, I was able to start the JBoss AS successfully by executing ./run.sh in the bin sub-folder of the installation directory.
Then I followed this guide to install Restcomm JSS7 stack. For that, I downloaded restcomm-jss7-7.4.1404.zip, unzipped it to /opt/ and then navigated to the ss7-jboss sub-directory and then executed ant deploy,
and the result was
...
BUILD SUCCESSFUL
which according to the guide is an indication of the service deployed successfully.
Then I am following CHAPTER 4 SECTION 4.1 of this user manual to run it as a JBoss AS Service. According to it,
All you have to do to start the Service is start the JBoss AS. This
will automatically start the SS7 Service. To start the JBoss Server
you must execute the run.sh (Unix) or run.bat (Microsoft Windows)
startup script in the /bin folder (on Unix or
Windows).
TWO PROBLEMS:
My <jboss_install_directory>/bin does NOT have a run.sh script. Because of this reason, I tried by running JBoss AS by using the regular standalone.sh script.
Next in the user manual, it is stated:
Result: If the service started properly you should see following lines
in the Unix terminal or Command Prompt depending on your environment:
(Note: I have pasted the following excerpt from user manual here, since it is too long to paste in this question.)
But I see none of those lines in my terminal. Rather, my terminal output of running ./standalone.sh is pasted here.
So I don't know how and where to proceed from here. Please help.
NOTE: This question is NOT a duplicate of my other question. Like I mentioned in the question titles, this question is about why my JBoss AS installation doesn't contain a run.sh script, and what would be its alternative. The other question is about some possible command to find out the JBoss Services started when it is running? When a beginner is starting to learn something, their entire purpose Not getting the job done. They have many confusions/questions in their mind.
The documentation documents how to start a JBoss 5.1 server but your installation uses a JBoss 7.1 server, which is why you have to use standalone.sh instead of run.sh to start the server and why the logs are different.
Since you correctly reach the JBoss AS 7.1.0.Final "Thunder" started in 3955ms line I wouldn't worry too much (except about using a documentation that is clearly outdated).
The documentation of your product only declares compatibility with JBoss 5.1.0. While it may work on later releases, you might want to check if there's a more recent version of your product. I wouldn't recommend installing JBoss AS 5.1.0 as it isn't supported anymore and will contain security breaches.
Can anyone please explain the below problem.
I'm using tomcat 8 and when I'm trying to start startup.bat file, the command prompt is opening and closing immediately just like blinking. However in the past while I'm working with java programs it worked fine but recently I installed Xampp and there in it again tomcat is downloaded "C:\xampp\tomcat". The same problem comes here in this folder as well, when I try to run startup.bat file. But when I use "XAMPP control panel" to start the Tomcat its able to get start and I'm getting "localhost:8080" start page in the browser.
The connector port for both tomcats are 8080 and I tried with changing the port number in tomcat 8 but no use. There should not be 2 tomcat servers in a single system? If not, why? (I've not installed them, both are in C drive)
I want to work with java servlet programs now.So I need use of tomcat. I've set below environment user varibles:
JAVA_HOME to C:\Program Files\Java\jdk1.8.0_65;
path to C:\Program Files\Java\jdk1.8.0_65\bin;C:\apache-maven-3.3.9\bin
Please suggest the solutions.
Thanks in advance.
I think you should check the tomcat log to find some clues, it is in log folder of your tomcat installation folder. Maybe you have missed some startup variable in start.bat for your new installed things.
BTW, if you want to keep seeing what happened in startup, try to run startup.bat in a command line console, but not double click it through your mouse. It will continue on generating log output in that console.
I can view the webpage after deploying the war file.when i open the page for next day i cannot view the page again after restarting the apache tomcat server the page opens.
You must have shut down the machine. When you come on next day and access the same URL then you won't be able to see that page. You will have to restart the tomcat server again to see that page.
I assume you use Linux and encountered the same issue when security patches/ OS hardening is performed on the server where apache tomcat runs. Below is the way I tackled the problem starting tomcat right after server reboots.
You will need to use CronScheduler and is pretty easy. The Cron daemon is a built-in Linux utility that runs processes on your system at a scheduled time.
Open a Terminal
Type --> crontab –e
Add following Line into Crontab --> #reboot [path to tomcat`s startup.sh shell script in tomcat`s bin directory]
Press ESC key and Press ':' and Type "wq" (Save the changes into Cron via VIM/ VI)
Type crontab -l (This will show you the reboot statement added means all OK)
The job defined by this string runs at startup, immediately after Linux reboots.
