Can we set values to only for some of the properties in Atomikos JTA properties and get the default values specified in jta.properties for others?

Question

I want to set value of com.atomikos.icatch.log_base_name property to transaction-log and value of com.atomikos.icatch.log_base_dir property to /log_dir. I need to change only these two and get the default values for all other properties in the jta.properties file. Can I do this by specifying the above two properties in a transactions.properties file and give its path as a system property to com.atomikos.icatch.file? Will the default values for the other properties be accessed using the jta.properties file if I am not specifying them in my transactions.properties file?

Answer 1

Here is how it works:

1. built-in defaults are loaded first
2. properties in transactions.properties are loaded and override 1
3. properties in jta.properties are loaded and override 2
4. properties in a custom "file" override 3
5. JVM properties (System properties) override 4
