To perform the necessary configurations, press the Config button next to your application server. In the case, you have several application servers you can configure them together or separately. To do this follow the steps:
Open the drop-down menu at the top of the configuration tab. It includes the list of all of the app servers in your environment.
Choose the one you need and make the configurations.
- only for the chosen server click Save only for current instance button from the drop-down menu;
- for all the servers click Save.
Note: if you create/rename a file or folder in the Configuration manager, this will be applied only in the list of the chosen node. You can’t save this change for all of the app servers available in the environment. If you want to also create/rename the file or folder in the other servers you need to do this manually.
Below you will see the list of the configuration files available for editing in the Java application servers:
- Tomcat 6
- Tomcat 7
- TomEE
- GlassFish 3
- Jetty 6
To get more information on which settings can be changed in the provided config folders, use the appropriate descriptions:
- server
- home
- webapps/work
- JAVA_HOME
- lib
- cron
- keys
- contexts
- server_lib
- apps
SERVER
The main Java servlet container configurations are performed in the files, located in the server folder.
Using the following config files, you can perform the actions listed below (these are just some examples):
context.xml
- configure session replication via Memcached
web.xml
- configure remote access via WebDav
- enable Multiple Domains
- configure memory settings for your java containers by stating your custom GC,
-Xmx, -Xms parameters (use standard parameters stating each at the new line):
-Xms< size >m
- set your custom environment variables for your Tomcat, TomEE, Jetty or GlassFish:
-Dmy.var3=/my/value
- configure JavaAgent interceptor
- enable remote debugging:
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address={port_number}
Note that this file is available only for Tomcat 6,7 and TomEE application servers. For configuring a GlassFish server, use the Admin Panel.
WEBAPPS / WORK
The webapps (for Tomcat/TomEE) and work (for Jetty) folders are used for storing the unpacked application deployed to the environment.
LIB
The lib folder is used for storing default and uploading custom jar libraries.
CRON
App servers include a cron folder with the config file, where cronjobs can be configured.
KEYS
It can be used for different cases by simply stating the path to your key:
/var/lib/jelastic/keys/{key_file_name}
