Trace flow of method call

Christophe Elek [IBM]

All,
a couple months ago i found a java property that would allow me to trace
the method in/method out of my packages

it looked like

java -D<property>=org.mypackage.* <main class>

Which would trace all in/out of each method in my package...

I cannot find the doc :( anyone knows what I am talking about ?

Thanks IchBin,
The link did not provide me with the answer... directly :)
They reminded me it could be a IBM JDK thingy and not a SUN one

I found IBM JDK has such a feature, named method trace (which I do not see
in SUN JDK)
It is -Xtrace in JDK 5 and -Dibm.dg.trc.methods in JDK 1.4.2

http://www-128.ibm.com/developerwork...jdk/diagnosis/
Interestingly, IBM JDK also has a java API to dump a stack trace... :)

com.ibm.jvm.Dump#JavaDump()/ #HeapDump() / #SystemDump()

Thanks for the hint though :)
