lttng-ust provides JUL and log4j java agents that leverage the current lttng stack.

We do not provide a Java CTF writer as is AFAIK.
Cheers.

Hi Lea,
Trace Compass has some branches that try out CTF writing, I would like to know, are you looking to trace your execution (JUL log into LTTng is the best answer there) or do you want to output results of a simulation to CTF? in that case, maybe we can help.
Matthew

Hello,
I am working on a Java API that permits to create UML state machine and to run them. I have created a Java interface allowing to implement customizable trace for this tool: the user can implement its own way to gather information from the execution for instance print in the console via System.out.println() or print in a xml file, etc...
In the scope of the project I am working on I would like to provide the users a Java class implemeting my interface with the CTF format but I can not manage to find a code able to write a CTF trace in Java.
Does such a code exist?
Since CTF traces seem to be really specific I do not want to intent to write my own version of a CTF trace because I am scared it would not be accurate and would not work with the already existing CTF readers.
Thank you in advance.
