I have been reviewing the jetspeed 2 build process and believe it could be improved in several areas.
1. using maven features appropriately within the current project structure. For instance, it appears to me that using the multiproject plugin instead of the reactor can replace about 236 lines with 2 in the top level maven.xml file.
+1 we've been meaning to look into that.
2. restructuring the project to eliminate conditionals and clarify dependencies. Currently the build appears to be oriented entirely toward deploying on tomcat, and from my brief review this appears to permeate many areas of the project. I suggest removing all such dependencies from current build files and creating a new set of modules for each installation environment,
installation/tomcat installation/weblogic installation/geronimo ...
that will customize as appropriate for the target environment and provide appropriate installation tools.
Sounds good to me. Might want to include JBoss in there too ;-)
Similarly, I think it might be advisable to factor out the database setup support into separate modules such asWe generate the scripts with Torque. So the installation is generic across all databases. Thus Im -1 on this one
installation/database/hsqldb installation/database/oracle ...
I have not yet discovered to what extent the persistence support is pluggable, but if for instance you are using ojb via its jdo support the choice of jdo vendor and appropriate setup could also be isolated in separate modules.The persistence plugin allows you to swap out OJB with another persistence framework such as Hibernate or Castor DB.
IMO JDO would lessen the need for a persistence plugin, since we would always write to the JDO APIs and then JDO would function much like the plugin.
Unfortunately open source JDO implementations are still lagging behind the Hibernate and OJB non-standard implementations
Is Geronimo going to support JDO?
No objections to multi-project, target environments
I'd like to know if there are objections to this approach before I spend a significant amount of time experimenting with it.
However Im -1 on the installation/database/* proposal unless you can improve on the current process
Many thanks, david jencks
