What is the main reason of a *.war file can't create anything at Tomcat?

Question

I'm trying to use Oxalis, which is an API for sending and receiving UBL document via specific AS2 protocol. Installation guide can be found at https://github.com/difi/oxalis. Pre-requiremetns are Java 1.8, Maven 3.x and Tomcat 9.0. My problem is, at end of instructions of installation guide, i obtain a oxalis.war file (Also i've already tried to do other guide, you can see at http://mmnclk.com/peppol-access-point-oxalis). After that i copy to the webapps folder of Tomcat. But after when i start Tomcat, being created oxalis folder. And I expect to see different files in this folder but only I have META_INF and WEB_INF folders. What could be the main reason of this? If you guys can help me, I would be very pleased.

Edit: After @slawek_k post, I got the following output.

c:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps>jar tvf oxalis.war

At the same time, as you can see in following link, i can't start application under the /oxalis folder under the manager application of Tomcat. When i tried to start just refresh the page.

Manager App

Note 1: This is my oxalis folder in the webapps folder.(This created after i put oxalis.war folder into the webapps)

My Oxalis Folder

Edit 3: When start Tomcat server i got this output.

Tomcat Start Error

The reason is probably that your war doesn't contain anything else. Why do you think it should contain anything else? What else do you expect to contain, and why? Why do you even care about that directory and don't test if the app behaved the way it should? — JB Nizet, Dec 25 '17 at 12:31
Because according to installation guide, after follow instructions,I should have seen some files (e.g. status, as2). But i didn't see anything. I've tried to contact with contributer but i didn't any response from him. — Kıvanç Eren, Dec 25 '17 at 14:11
I checked my log files. And i had punctuation error in my oxalis.conf folder i solved this. By the way, in localhost-access.log, i get 404 not found when server requests GET /oxalis HTTP/1.1". — Kıvanç Eren, Dec 28 '17 at 12:12

Check the environment of the user who has created the .war file. Especially the permission right. Control the contents of the .war file.

jar tvf yourfile.war

The permissions right of all files should match with the tomcat environment. Check the permission of your running tomcat ( tomcat or root ) environment and compare it with the one of your .war file.

Hi, thanks for your reply. After did this i got "Error: Could not find or load main class jar" message. I've looked for this problem and i found some solutions for that, but they didn't work for me. – Kıvanç Eren Dec 26 '17 at 11:01
Sorry for my delayed reply. I've edited my message with output of command. – Kıvanç Eren Dec 28 '17 at 07:03
By the way, i want to make a better explanation. I download this project from GitHub and after that i build with mvn clean install via cmd (and alsı i tried over Linux). And i obtain an oxalis.war file. After that i put this file into Tomcat webapps folder and after that create a directory which is oxalis file. According to the installation guide i can access https://localhost/oxalis/status but when i try to reach this url, i'm getting error everytime. And when i look at the oxalis folder, i see only two directories (WEB_INF and META INF). But i guess i should see other files. – Kıvanç Eren Dec 28 '17 at 07:11
This problem is known. See for example https://stackoverflow.com/questions/40204124/how-to-fix-jars-that-were-scanned-but-no-tlds-were-found-in-them-in-tomcat-9 – slawek Dec 29 '17 at 10:32
If I understood corectly, your war-file is not deployed completly and is not running. Try to restart the application and watch the messages. If your application is not started you should see any messages in catalina.out when you deploy your application.. Can you post the catalina.log if you copy the oxalis.war. – slawek Dec 29 '17 at 11:05
I don't have catalina.out. I tried this post (https://stackoverflow.com/questions/3424515/not-to-log-to-catalina-out) and nothing happened. But i edit my first post and you can see what happened about oxalis when start tomcat. – Kıvanç Eren Dec 29 '17 at 13:50
In your logging.config.file=C:\Program Files\Apache Software Foundation\Tomcat 9.0\conf\logging.properties set org.apache.catalina.core.ContainerBase.[Catalina].[localhost‌].level = FINE and/or org.apache.jasper.servlet.TldScanner.level = FINE to see more in catalina.log. You can find where is your catalina.log in the scripts setenv.sh or catalina.sh ( under Windows similar name but another suffix ). After you set new debug level , restart tomcat. You should see the jars without tlds. Post these log – slawek Jan 01 '18 at 08:42
@KıvançEren did you run this on windows using tomcat alongside? – Juliyanage Silva Feb 16 '22 at 15:21

What is the main reason of a *.war file can't create anything at Tomcat?
