ant build.xml windows white space in path
Change it to
appserver.home="C:\\Program Files\\Apache Software Foundation\\Tomcat 6.0"
Variant with "/" instead "\" works on my system. Just need to delete " symbols before and after path structure.
Find the Windows short name for those directories using dir /x and use thme when setting path values.
Some more discussion at How does Windows determine/handle the DOS short name of any given file?
