Hi,
I'd like to deploy forrest as a webapp, and include the environment as a
parameter in the command line. This parameter should be used to set some
variable in the site.xml, depending on the environment targeted.
Any way to pass variable from Ant to site.xml?
I'm not aware of any easy way to do this in 0.7, it can be done in
0.8-dev very easily.
Do you want the hard way (0.7) or the easy way (0.8-dev)?
Either way, please provide a speicifc example of what you want to do,
i.e. what property, how will it be used. Please provide code where
possible, it prevents confusion in the explanation.
Ross
I prefer the hard way ;.)
Glutten for punishment eh?
In my site.xml, some part of href attributes needs to be set to the right server
adress.
In the xml:
<site ...>
<external-refs>
<mySite href="http://localhost:8080/"/>
</external-refs>
</site>
I would like to replace the 'localhost' and the '8080' by some environment
parameters comming from the command line used to build the war, or coming from
properties choosen with this parameter.
Before I go into the solution I have in mind let me ask a couple of
questions, I'm not sure an "environment parameter" is the right idea.
Since you are building a war the values are static once built. So why
not just change them in the site.xml file before they are built?
You could do this manually each time it is built, or, if you need to
automate it you could write an ANT task that takes the property value
from the command line, builds the correct site.xml file using filtersets
and then continues with a normal forrest build.
See http://ant.apache.org/manual/CoreTypes/filterset.html for more info
To see a fairly clear example of how to use this take a look at the
seed-plugin template in "FORREST_HOME/plugins/build.xml".
Doing it this way means that you don't have to play with Forest core, so
you get easier upgrades between Forrest versions.
