Java Application Server Configuration

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:

  1. 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.


  2. Choose the one you need and make the configurations.

  3. To apply the changes:
  • only for the chosen server click Save only for current instance button from 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:

To get more information on which settings can be changed in the provided config folders, use the appropriate descriptions:

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

HOME

If you need to use any custom files/folders for configuring your application you can download/create them in the home directory which is used as a storage in your Java server.

As a result you can make configurations specifying the path to your downloaded/created files in the variables.conf file (server folder).


Note: though the server's directory, which refers to this folder, can be named temp for some servers, it is never automatically cleaned by Jelastic system.

WEBAPPS / WORK

The webapps (for Tomcat/TomEE) and work (for Jetty) folders are used for storing the unpacked application deployed to the environment.

KEYS

The keys directory is used as a location for uploading any private key which is needed for your application.

Generate the key, save it as a simple file and upload to the key folder.
It can be used for different cases by simply stating the path to your key:

/var/lib/jelastic/keys/{key_file_name}
