# Installation

To install this module, you need to install Java JDK Headlees, e.g.:

> apt-get install default-jre-headless

# Configuration

In order to start signing PDF documents you need to configure certificate(s) to use in your company.

- Go to `Settings > Companies > Companies > Your company`
- Go to `Report configuration` tab
- Click `Edit`
- Add a new item in `PDF report certificates` list
- Click `Create`
- Set name, certificate file, password file and model
- Optionally you can set a domain and filename pattern for saving as attachment

For example, if you want to sign only customer invoices in posted state:

- Model: `account.move`
- Domain: `[('move_type','=','out_invoice'), ('state', '=', 'posted')]`
- Save as attachment: `(object.name or '').replace('/','_') + '.signed.pdf'`

Note: Linux user that executes Odoo server process must have read access to certificate file and password file

## Java Memory Settings

If you are signing large amounts of reports at the same time, or if you have a lower worker memory size than the JVM defaults, you may need to tune the JVM heap memory limits. Do so by adding a `$JVM_ARGS` environment variable that contains the required flags. Check out these links too:

- StackOverflow answer.
- Java docs.

# Usage

User just prints PDF documents (only Qweb PDF reports supported) as usual, but signed PDF is automatically downloaded if this document model is configured as indicated above.

If ‘Save as attachment’ is configured, signed PDF is saved as attachment and next time saved one is downloaded without signing again. This is appropiate when signing date is important, for example, when signing customer invoices.

You can try the signing with the demo report that is included for customers called “Test PDF certificate”.

You can set extra parameters of JSignPdf library in the system parameter named ‘reportqweb_signer.java_position_parameters’, for example ‘-V’ to visible signature into pdf. You can also set extra parameters for Java in the system parameter named ‘reportqweb_signer.java_parameters’.

# Known issues / Roadmap

- When signing multiple documents (if ‘Allow only one document’ is disable) then ‘Save as attachment’ is not applied and signed result is not saved as attachment.
- Add tests.
- Why not taking the occasion to add the whole configuration at report level (if to be signed or not, the domain, etc…)? See https://github.com/OCA/reporting-engine/pull/533#issuecomment-898321161
