Thanks Doru ! I will see want I can do.

I used it with a couple of hand made profilers for some funny situations but not by instrumenting Java with Agents. What are the funny situations in which you have used this ? Because I am trying to find features to Moose what the others software can’t do. I also think that the Agent solution is the most robust way to go. I think I will take this solution. I found the sources of Java wiretap (https://www.iam.unibe.ch/scg/svn_repos/Students/fierz/profiler/) and it seems to use an agent. Yes, it did. But this is not maintained anymore and it was not more than a prototype at the time. Would you be interested in having this solution open-source? For now the solution will be not open source, but I will discuss this with my hierarchy. Ok. It's your prerogative :) However, if you only need the execution of SQL statements, you might also consider retrieving this information from log files. For example, if you have an application server, you can typically use a log4j configuration to output the SQL executions. Then you can parse the log file and create a report for that. You might not even need Dynamix. Ok. But the execution of SQL statements is just an example. And if I use log4j I have to modify the source code and I can’t do it, can’t I ? I simply pointed out that for quick things you can find other solutions that are not necessarily generic. In the case of SQL, it is very likely that you can enable the logging only by affecting a configuration while the production system is running without changing the code and without even restarting the system (yes, minor updates like these are possible even in Java :)).

They have many software projects (mainly in Java) and they want to audit them. The goal of my internship is to evaluate how Moose can be used to do this audit (performance, architecture, etc...) and be automatized to execute checking rules. A part of the audit is to see how a program interact with a database by counting the requests that are done. I thinks that part can't be deducted easily from the static model, so I thought to use Dynamix. I have already the static model of the program imported by VerveineJ in Moose and I want to instantiate the Dynamix part. So I search how I can do this. I can't modify the source code but I can add an agent on the JVM to see the calls made. That is why Java Wiretap seemed interesting.

Most of the time, a simple aspectJ aspect is good enough to gather the data. You then need to dump your data into a .mse file. The MSE file has to be fit with the Pharo model you have. And since you probably want to have the structure of the code, you probably need a second .mse file, obtained from VerveineJ. I am interested in that work.
