IPluginServletAction (FORMCYCLE: BOM 7.0.2 API)

All Superinterfaces:

IFCPlugin, INamedUiElement, INameProviding, ITransferable, Serializable
```
public interface IPluginServletAction
extends IFCPlugin
```
Interface for plugins servlet action plugins. A servlet action plugin is called in response to a HTTP request to a certain URL. The plugin may perform any arbitrary logic and send a response to the HTTP request. It can be used, for example, to serve resources (statically or dynamically) or to trigger certain actions within the system from the outside.
Assuming FORMCYCLE runs on the URL https://example.com/formcycle, the URL to a servlet plugin looks as follows:
```
 http://example.com/formcycle/plugin?name=PLUGIN-NAME&client-id=CLIENT_ID
 
```
The given PLUGIN-NAME determines which servlet action is executed. The PLUGIN-NAME must be the IFCPlugin.getName() of the plugin. The CLIENT_ID must be the ID of the client where the plugin was installed. It must be omitted in case the plugin was installed as a system plugin. When no servlet plugin with the given name exists, a general error response is returned.
