Sonar Integration Tests Coverage not show + Selenium + Jboss +Jacoco - selenium

Question

I use Sonar 4.1.1, Jboss 6.x, Jacoco 0.6.4, execute tasks with Ant I am not allowed to use Maven. In an eclipse workspace, I have two projects, one is the web application another is selenium test.
I am able to get unit test and code coverage for unit test. But sonar is not able to read the integration test file created by Jacoco. I think there might be something wrong with the way I create jacoco-it.exec file so sonar can't read it. Because sonar does read my jacoco-ut.exec file. And I am able to have both reportPath and itReportPath to read my jacoco-ut.exec file with no problem. Also thinking maybe is something wrong in my build file. I did a lot of research and tried many different ways to create the jacoco-it.exec file, different Jacoco settings and followed different examples from sonar, jacoco, other blogs but still doesn't work. I must be missing something Help!! Thanks!!
I have VM arguments for Jboss like this
-javaagent:/path to jar/jacocoagent.jar=destfile=/path for create/jacoco-it.exec
When I run selenium, the above code create a file with some data, size about 1.3MB
Here is the part of build relate to this issue

Answer 1

The reason for that is, may be you are NOT attaching Jacocoagent.jar file to the "TARGET" (ex: JBoss / Tomcat) JVM's scope and stopping it so that it can flush the final code coverage data to the jacoco it exec file.
Once you do that (instead of using Maven/ANT's JVM scope), run your non-Unit (IT) tests and then STOP the target JVM.
After the target JVM is stopped, you'll get the final jacoco .exec file genreated for the IT tests. Use that file for sonar.jacoco.itReportPath variable and it'll work.
For ex: I pass/have this variable to the Tomcat's startup.sh script and while starting tomcat (target JVM), I use this variable within the Tomcat's actual start command.
