Hi
Thanks for the tips, but so far I have not managed to understand it.
How does Merlin decide what to start when it reads a block.xml that contains several
components and services?
In a simple Java application, there is main method that is the entry point for the
application. I would assume that Merlin is a container that deploys several
components and services, but somewhere in the process, there should
be something that resembles a main method. How does Merlin manage that?
As it comes to OpenIM, I am trying to learn Merlin by looking at the source code and
configuration of OpenIM.
The way I can see, it starts a .bat file that in turn starts merlin.bat. It supplies
merlin.bat with a jar-file, kernel.xml and config.xml. I could not find any thing
special in those xml-files, but I guess the real story is hidden somewhere
in the block.xml? Certainly, CLI is involved here.
BTW, I am running Merlin 3.3.
Thanks.
Best Regards

Subject: Entry point in block.xml in Merlin
Hi
I am trying to understand what the entry point in a block.xml is.
For example, I looket at OpenIM that is built upon Merlin. OpenIM is launched with:
merlin .... openim\jars\openim-server-impl-1.2.jar
Now when I look at the block.xml filen within the above jar file, I find lots of
component definition, but I cannot see which component is launched first.
Please help.
Thanks.
See the enclosed block.xml from openim.
Best Regards
