Subject Re: Geronimo instances on the same server
Date Wed, 23 Aug 2006 12:16:26 GMT
Hello John,

Here is a quick summary of how this could work.

Out-of-the-box, Geronimo uses var/config/config.xml to identify the  
modules to be loaded upon start-up and also to override the out-of- 
the-box configuration of these modules (for instance, virtual hosting  
can be overridden in this configuration file).

As each developer needs to have full control of the modules that they  
want to start along with their configurations, each developer needs  
to have a dedicated config.xml. Also, each developer needs to have  
their own copy of the var directory. This copy can be rooted wherever  
you want. You can use one of the two following system properties to  
specify where this copy is located:

1. this property specifies the  
relative path of the cloned var folder.
2. org.apache.geronimo.home.dir: this property specifies the full  
path of the cloned var folder.

Whatever the method used, each developer needs to put their own  
config.xml file in var/config. At least, each developer should be  
allocated with dedicated HTTP, JMS et cetera ports and their  
config.xml should mirror this allocation. Note that you cannot simply  
allocate a virtual host to each developer.

Developers sharing the same server share the same Geronimo  
repository, i.e. the repository folder. This implies that a developer  
can see the modules deployed by other developers and can also  
override them. So, I think each developer should be allocated with a  
dedicated moduleId to prevent the override problem.

I may be wrong but I believe it is possible to add a dedicated  
repository for each developer. Perhaps that someone else can comment
