Store submitted data
[AEM Forms 6.5]{class="badge informative"}
The next step is to store the submitted data in the AEM Author’s repository. The servlet mounted on /bin/startworkflow saves the submitted data.
An AEM workflow launcher is configured to trigger every time a new resource of type nt:file is created under the <node_to_store_submitted_data> node. This workflow will create non-interactive or a static PDF by merging the submitted data with the xdp template. The generated pdf is then assigned to a user for review and approval.
To store the submitted data under <node_to_store_submitted_data> node, we make use of GetResolver OSGi service, which allows us to save the submitted data using the fd-service system user which is available in every AEM Forms installation.
The node under which the submitted data is stored can be configured using the ConfigMgr as explained in deploy sample assets
