These properties are used to configure cOnException running in the Standard Job framework.

The Standard
cOnException component belongs to the Exception Handling family.

Basic settings

Usage

1. Drag and drop these components from the Palette onto the workspace: a cOnException component, a cFile component, a cBean
   component, and cProcessor component.
2. Link cFile to cBean using a Row >
   Route connection.
3. Link cBean to cProcessor using a Row >
   Route connection.
4. Label the components to better identify their roles in the Route.

1. Double-click the cOnException component,
   which is labelled Ignore_exception, to
   open its Basic settings view in the
   Component tab.
   

2. Click the plus button to add a line in the Exceptions table, and define the exception to catch. In this
   example, enter java.io.IOException to handle IO
   exceptions.
   In the Exception behavior area, select
   the Ignore the exceptions option to ignore
   exceptions and let message routing continue. Leave the other parameters as
   they are.
3. Double-click the cFile component, which
   is labelled Source, to open its Basic settings view in the Component tab.
   

4. In the Path field, enter the path of the
   message source, and leave the other parameters as they are.
5. Double-click the cBean component, which
   is labelled Throw_exception, to open its
   Basic settings view in the Component tab.
   

6. Select New Instance and in the Bean class field, enter the name of the bean to
   throw an IO exception, beans.throwIOException.class in this scenario.
   Note that this bean has already been defined in the Code node of the Repository
   and it looks like
   this:

   package beans; import java.io.IOException; import org.apache.camel.Exchange; public class throwIOException { /** * @throws IOException */ public static void helloExample(String message, Exchange exchange) throws IOException { throw new IOException("An IOException has been caught"); } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

   package beans;   import java.io.IOException;   import org.apache.camel.Exchange;     public class throwIOException {       /**        * @throws IOException      */     public static void helloExample(String message, Exchange exchange) throws IOException {         throw new IOException("An IOException has been caught");     } }

   For more information about creating and using Java Beans, see
   
   Talend Studio User Guide.
7. Double-click the cProcessor component,
   which is labelled Monitor, to open its
   Basic settings view in the Component tab.
   

8. In the Code area, customize the code to
   display the file name of the consumed message on the Run console:
   System.out.println("Message consumed: "+ exchange.getIn().getHeader("CamelFileName"));

   1 2	System.out.println("Message consumed: "+ exchange.getIn().getHeader("CamelFileName"));

9. Press Ctrl+S to save your Route.

1. Click the Code tab at the bottom of the
   design workspace to check the generated code.
   

   As shown above, Ignore_exception handles any IO exception
   thrown by .bean(beans.throwIOException.class) invoked by
   cBean_1, so that messages from the endpoint
   Source can be successfully routed onwards
   (continued(true)) in spite of the exception.
2. Press F6 to execute the Route.
   The route gets executed successfully and the files from the source are
   successfully routed to the destination.
   

3. Change the exception handling option in the cOnException component or deactivate the component and run
   the Route again.
   The exception thrown by the Java bean prevents the messages from being
   routed successfully.
