4.4. Important notes
Important notes for the Fuse 7.2 release of the Fuse standalone distribution:
- Generating an authentication token for camel-linkedin
LinkedIn has started responding to login forms using a CAPTCHA, which makes it impossible to use the username/password login approach for a standalone headless Fuse process. As an alternative the component was enhanced so that a LinkedIn access token can be generated and configured in an
accessTokencomponent property. Also anexpiryTimeproperty allows configuring the token expiry time in milliseconds since the Unix Epoch, which defaults to 60 days if not provided. The component tries to login again if the token expires, but the username/password approach is likely to result in a CAPTCHA response and a failed login. Hence the component is unable to automatically refresh tokens on its own.The token can be generated using a web browser and a utility such as
curland following the OAuth login process for LinkedIn as documented at https://developer.linkedin.com/docs/oauth2. As the document describes, user needs to login using a browser to generate an authorization code, which in turn is used to generate an access token to be configured in the LinkedIn component. The generated token is valid for 60 days, so the process has to be repeated periodically to manually update the token and the Fuse application needs to be restarted with the refreshed token.- camel-kafka component has been updated to use Kafka 2.0.0 client
-
For better compatibility with AMQ Streams (Red Hat’s distribution of Apache Kafka), the
camel-kafkacomponent has been upgraded to use the the Kafka 2.0.0 client library. - Using XA transactions on AMQ connections
-
When using an XA connection to an AMQ broker, you should set the connection parameter
jms.xaAckMode=1on the broker URL explicitly for theXAConnectionFactory. Spring Boot actuator health checks may not work in this configuration and they should be disabled by settingmanagement.health.jms.enabled=falsein theapplication.propertiesfile.
