My application context is defined as an XML file located in
<Context docBase='/my/path/to/myApp/myAppWarFile.war'> <Environment name='my_config_dir' value='/my/path/to/myApp' type='java.lang.String'/> </Context>
/my/path/to/myApp contains the WAR file myAppWarFile.war and a number of externalized properties that are read by Spring.
Tomcat is configured with autoDeploy turned off. When I start Tomcat, it creates
my/path/to/Tomcat/conf/webapps/my-app/ and the WAR file gets unpacked into this location as expected, and the application of course can run as expected.
When I want to deploy a new version without restarting Tomcat, I run the undeploy command as follows:
curl http://localhost:8080/manager/text/undeploy?path=/my-app --user my-username:my-password
... and that works. But when I instruct Tomcat to deploy with the following curl statement, I get a failure.
curl http://localhost:8080/manager/text/deploy?config=file:/my/path/to/Tomcat/conf/Catalina/localhost/my-app.xml --user my-username:my-password # Tomcat response FAIL - Invalid context path null was specified
Adding the path does not help much, I still get a failure.
curl http://localhost:8080/manager/text/deploy?config=file:/my/path/to/Tomcat/conf/Catalina/localhost/my-app.xml\&path=/my-app --user my-username:my-password # Tomcat response FAIL - Failed to deploy application at context path /my-app
The worst part is that tailing catalina.out does not yield any insight. And on top of that, Tomcat deletes the application context XML file
Naturally I have reviewed Tomcat documentation (https://tomcat.apache.org/tomcat-8.0-doc/manager-howto.html#Deploy_using_a_Context_configuration_%22.xml%22_file) and I have googled all day to figure this out, but I have not found anything that can help me with this particular configuration.
It feels as though the choice is:
- Tomcat with autoDeploy on (not recommended for production) in which case simply dropping the new WAR to
/my/path/to/myApp/will cause Tomcat to hot deploy the app.
- Tomcat with autoDeploy off, but re-deploying requires a Tomcat restart because the deploy API does not seem to be working as advertised.
Has anybody made this work with this configuration?
I turned up the logging on Catalina. When I run the first deploy command without the path, I get this set of log entries:
