Package org.imixs.workflow.wopi

Class WopiDocumentConverterAdapter

java.lang.Object

org.imixs.workflow.wopi.WopiDocumentConverterAdapter

All Implemented Interfaces:

org.imixs.workflow.Adapter, org.imixs.workflow.SignalAdapter

public class WopiDocumentConverterAdapter
extends Object
implements org.imixs.workflow.SignalAdapter

The WopiDocumentConverterAdapter can be used to convert office documents into PDF and other file formats. The Adapter simply calls a build in RestAPI of Collabora to convert documents based on the JODConverter (https://github.com/sbraconnier/jodconverter)

There is no need to implement the libraries in case a Collabora instance is up and running. In this case the rest API endpoint 'lool/convert-to/' provides a convenience function. See details here: https://www.collaboraoffice.com/de/document-conversion/

Documents can be converted into different formats by calling the corresponding endpoint.

• https://localhost:9980/lool/convert-to/pdf for pdf
• https://localhost:9980/lool/convert-to/png for png

The rest service automatically detects the input document format.

The adapter simply posts a given document to the service endpoint. The adapter can be configured by the event workflow result:

 
    <wopi-converter name=
"api-endpoint">https://localhost:9980/lool/convert-to/</wopi-converter>
    <wopi-converter name="filename">......</wopi-converter>
    <wopi-converter name="convert-to">pdf</wopi-converter>
   
 

The Collabora API endpoint must point to a collabora instance. The 'filename' is the file attached to the current workitem. This can also be a regular expression. The option 'convert-to' is optional and default value is 'pdf'
