This behaviour (called Dynamic Variables) is already integrated in
 izpack 3.11. Look at the documentation on how to use it.

Betreff: [izpack-devel] variable substitution

Hi all,


I am defining a number of variables in my install.xml file e.g.
    <variables>
        <variable name="mcs.drws.device.repository.url"
 value="${INSTALL_PATH}/devicerepository/devices.mdpr"/> 
        <variable name="mcs.drws.cache.dir"
 value="${INSTALL_PATH}/webapp/WEB-INF/cache"/>
        <variable name="mcs.drws.log4j.config.file"
 value="${INSTALL_PATH}/webapp/WEB-INF/drws-log4j.xml"/>
        <variable name="mcs.drws.allow.non.secure.access"
 value="false"/>
    </variables> 


These are supposed to be substituted into various files at install
 time. And they are, however the 
${mcs.drws.device.repository.url} 
substitution point in one such file (for example) gets the value 
${INSTALL_PATH}/devicerepository/devices.mdpr
rather then also having the ${INSTALL_PATH} part replaced with the
 install time value.

It looks like either 
a) variables can not have substitution points in their own values
or
b) the variables are defined at compile time and never examined again.

I would like to modify this behaviour so the above example works (it is
 useful to have constructed variables esp. when they are paths as they
 get converted to platform specific paths at install)

Any hints on where this behaviour should be added?

Cheers


matthew
