Hi @Tessa_learner1, the ID field is use to set id attribute in html form element.

In general if you are using Action Type then you will not be able to use custom servlet. If you want to use your custom servlet with Form Container you will need to do some changes in Form Container component itself, as it does not give any configuration option to change servlet that handles it.

Please have a look into accepted message in this thread - [1] - it describes what needs to be done to use custom servlet with Form Container component - it's all there including sample code.

Nevertheless if you want to use custom servlet instead the one provided by Form Container, maybe it will be better to create your own custom form component - I have described few approaches in this thread - [2]

Hi @Tessa_learner1 ,

You need create sling Servlet using resource type and add  resource type to your form container component drop-down.then your Servlet getting called.
