List deployed webapps in Apache Tomcat

Question

I need to get a list of deployed webapps in Apache Tomcat. Also, for each webapp I need to get a list of initialized servlets and JSPs. Any ideas how this can be done?

Answer 1

In order to get a list of deployed apps of your tomcat you just need configure user/roles and use /manager/text/list tomcat endpoint

Configure user and roles in Tomcat

Add this in your /.../.../TOMCAT_HOME/conf/tomcat-users.xml

You could skip "admin-gui" & "admin-script" roles if you will not perform admin operations.

After that, restart tomcat

List apps using browser

Go to your favorite browser and enter this url:

http://some_ip:some_port/manager/text/list

A login will appear. Enter the user/password configured in your TOMCAT_HOME/conf/tomcat-users.xml

Using command line

Just execute this:

curl -v -u my_user:my_pass http://127.0.0.1:some_port/manager/text/list

The result should be:

OK - Listed applications for virtual host localhost
/manager:running:0:manager
/:running:0:ROOT
/docs:running:0:docs
/examples:running:0:examples
/host-manager:running:0:host-manager
/my_app:running:0:my_app
/my_other_app:running:0:my_other_app
....
* Connection #0 to host 127.0.0.1 left intact

List apps with curl is used by a plugins related to automated tomcat deploys (Devops)
