[Shaheer4636]

I have added all vprofile-2.war to /var/lib/tomcat9/webapps/ROOT.war. But still the webapp is no accessible on the browser. Its giving 404 error.

I have checked application.properties. they are correct and fine

Facing the same issue.....

I was able to resolve the issue.

First I checked the /var/log/tomcat9/localhost.YYYY-MM-DD.log file.

In the file, I could see RMQ errors:

Caused by: com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.
at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:342)
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:909)
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:859)
at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:1000)
at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:355)

This is is because the RMQ user was not created.

I then created the user and restarted the server.

sudo rabbitmqctl add_user test test
sudo rabbitmqctl set_user_tags test administrator
sudo systemctl restart rabbitmq-server

Then restarted tomcat9 also.

After that I was able to see the login page.
