OSGi PAX Logging Component (deprecated)

Since Camel 2.6

Only consumer is supported

The PAX Logging component can be used in an OSGi environment to receive PaxLogging events and process them.

Dependencies

Maven users need to add the following dependency to their pom.xml

<dependency>
  <groupId>org.apache.camel.karaf</groupId>
  <artifactId>camel-paxlogging</artifactId>
  <version>${camel-version}</version>
</dependency>

where ${camel-version} must be replaced by the actual version of Camel.

URI format

paxlogging:appender[?options]

where appender is the name of the pax appender that need to be configured in the PaxLogging service configuration.

By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

bundleContext (consumer)

The OSGi BundleContext is automatic injected by Camel
