[izpack-users] How does variable substitution work?

[Bartz, Klaus]

Hi lionel,
variables are only used at installation time, not at packaging
("compile"). 
<pack> and the targetdir of a <file> will be used at installation time,
the source
at packaging. The IzPack compiler uses the src path to catch the file
and put it
into the installation jar file. Therefore you cannot use an IzPack
variable at that place.
 
Ok, what todo? Use an ant build script where you can use ant replace or
so before
calling the IzPack ant task.
Look into the build script of IzPack.
%IZ_HOME%\src\build.xml
 
Cheers
 
Klaus

	Hi guys,
	 
	I have moreover the same problem with the variable substitution
but all in the install.xml
	 
	I declare a variable
	<variable name="TomcatVersion" value="tomcat-5.5"/>
	 
	and in <pack> tag I want to use like this:
	 
	<file targetdir="$INSTALL_PATH"
src="dnabi-install/${TomcatVersion}"/>
	 
	But he don't replace the variable...
	Any tips? Because for me it's very usefull
	 
	Thanks in advance,
	lionel

		Hi Gernot,
		variables will be not substituted by the contents of
variables.
		I see to ways to solve your problem. 
		
		1: write a custom action which does the substitution.
		
		2: use
		in install.xml
		...
		<variable name="APPLICATIONS_SUB_PATH"
	
value="/OpenOffice/orgPortable/App/openoffice/program/soffice.exe"/> 
		...
		
		in your parsable file
	
<value>${APPLICATIONS_DEFAULT_ROOT}${APPLICATIONS_SUB_PATH}</value>
		
		Cheers
