BTM configuration settings are stored in a
Configuration object. It can be obtained by calling
TransactionManagerServices.getConfiguration(). All settings are documented in the javadoc.
How to configure BTM
Configuration object is implemented with sensible default settings. For a first time user, all default settings are good enough. After the initial testing phase, you might want to change some settings. This can be done in two ways: via a properties configuration file or by setting values directly on the
The properties configuration file
You can create a properties file in which you'll set some configuration settings. All the ones you omit will keep their default value.
The file can be stored anywhere on the file system in which case you need to set the
bitronix.tm.configuration system property to tell BTM where the file lies. This is generally done by adding a
-D argument to the virtual machine's command line:
Another way is to call the properties file
bitronix-default-config.properties and store it at the root of your classpath.
Setting values directly on the
You can call any setter you want on the object you get from the call to
TransactionManagerServices.getConfiguration(). This is convenient if you do not want to use the properties file to configure BTM but want to leverage - for instance - Spring instead.
Configuration object is a singleton, there is no need to pass it to any other object, BTM will pick it up at startup.
