Ant Property Madness??
Hi all,
today we upgraded to Ant 1.1. Before we had been using the prerelease for
quite a long time and were very satisfied so far. Today we made an odd
experience. Out init target setting all directories was placed somewhere in
the middle of the file. Before that were targets copying files, after that
targets compiling and zipping up classes. All properties are set in the init
target. With the old version everything was just fine. After the update, Ant
did not seem to parse the properties anymore and interprets them as plain
text. After some playing around with the buildfile, we figured out that
everything works fine if we place all targets using properties after the
init target. Did we miss something obvious? Please find a snippet of the
version not working anymore below.
Kind Regards
Daniel Hoppe

ANT and classpath problem (newbie)
Posted by Alberto Silva <al...@nmp.es>.
Hi,
I'm having an error when trying to compile with ant the sample web aplication that comes with tomcat-3.1 ($TOMCAT_HOME/docs/appdev/sample). I always get an eror about 'java.lang.NoClassDefFoundError'. I think the error is made by ant, but... I am newbie with Java, servlets and jsp, so i am not sure.
I get 3 diferent errors (I think the build.xml file is correct):
Error N1

Any idea?? The error changes and I have tried all the distributios from ant (ant1.1, ant1.0.8, ant from tomcat 3.1, ant from tomcat 3.0, src, nigthly, etc)
It seems that something is wrong with my jdk installation, I can't compile the ant or the tomcat src too, I always get the 'java.lang.NoClassDefFoundError'
My enviroment:
RedHat 6.1
JDK 1.2.2 Release Candidate 4
jswdk-1.0.1
jaxp1.0.1
Tomcat 3.1 (bin distro)
ant 1.1 (bin distro)
I would like to start making my own web applications, but without ant, it is imposible to me.
Lots of thanks for your support.

This is the way Ant 1.1 works and I'm a little bit puzzled as to why
it should have been different in earlier versions. Which version has
this been - i.e. can you remember when and where you've obtained it?
The behavior of <property> and ${} expansion has been changed in CVS
very recently, your old build files would probably work as expected
with 1.2alpha2 but I wouldn't recommend using it in a production
environment yet.
