Overview of the ServiceMix

...

Basic Example

This document describes how to run the Basic example and provides details about what it does. For information on the business use case, please refer to: Use Case for Basic.

The Basic example illustrates the following:

...

Code Block
cd [servicemix_install_dir]\examples\basic

 

Then type:

Code Block
[servicemix_install_dir]\bin\servicemix servicemix.xml

 

where servicemix_install_dir is the directory in which ServiceMix was installed.

Tip
titleHandy Hint

Add $SERVICEMIX_HOME\bin directory to $PATH variable to simplify execution of the example.

 

Stopping the Basic Example

To terminate the Basic example type "CTRL-C" in the command shell in which it is running and answer "y" to the "Terminate batch job (y/n)?" question.

Every 5 seconds logging information is written to the console, followed by information from the trace component. Note, that the triggers' property values of "name", "My Example Job", "group", and "ServiceMix" are displayed along with a timestamp. Typical output looks like the following:

Details

The following table provides more details about the function of each component and bean in the servicemix.xml file.

...

  1. Download the jencks-all-1.2.jar here.
  2. Wiki Markup
    Copy the jar file to \[servicemix_src_install_dir\]\assembly\target\servicemix-2.0.2\bin\servicemix-2.0.2\lib, where \[servicemix_src_install_dir\] is the directory in which the ServiceMix distribution is located.
  3. Delete jencks-all-1.1.1.jar from that directory.
  4. Wiki Markup
    Place a copy of the jar file in the ServiceMix web directory  at \[servicemix_src_install_dir\]\servicemix-2.0.2\tooling\servicemix-web\target\servicemix-web\WEB-INF as well.
  5. To run the example in the source distribution:
Code Block
cd [servicemix_src_install_dir]\assembly\target\servicemix-2.0.2\bin\servicemix-2.0.2\bin

..\..\bin\servicemix servicemix.xml

 

Note: It is not necessary to build the source distribution if you have previously done so. If ServiceMix has not been built, execute the above steps before building. The procedure on how to build the source distribution can be found here.
