Re: Building Struts with ANT question
Craig,
Thanks very much for your reply...guess I could have gotten that from the
ANT docs...sorry about that.

Ant provides a hierarchy of mechanisms by which properties can be defined.
Essentially, the following list is checked from top to bottom until an
appropriate definition is found:
* A command line setting (-Dservlet.jar=xx)
passed to Ant
* A system property named "servlet.jar" passed to
the JVM inside which Ant is running
* A setting inside the build script itself.
In the case of Struts, the build script ("build.sh" or "build.bat") that you use
looks for an environment variable named SERVLETAPI_HOME, and uses that to
construct an appropriate value:
java ... -Dservlet.jar=$SERVLETAPI_HOME/lib/servlet.jar ...
See the comments at the top of build.sh or build.bat for more documentation on
the environment variables you can use to control where the build gets its files
from. The Ant user's manual (which comes with the Ant distribution in file
"docs/index.html") is also very useful when trying to understand build.xml
files.

Building Struts with ANT question
I have successfully built Struts using the supplied ANT files, but have a
question. There are classpaths referencing the property ${servlet.jar} in
build.xml.. An example is the compile.example target...
