如何实现%%文件读取

[adonn]

我在win2000中设置环境变量set SUMIT_CONFIG=c:\sumit\
然后想在java代码中实现
File file = new File("%SUMIT_CONFIG%\\config.xml");
运行程序后报错
log4j:ERROR Could not read configuration file [%SUMIT_CONFIG%/log4j.txt].
java.io.FileNotFoundException: %SUMIT_CONFIG%/log4j.txt (The system cannot find the path specified)

Properties p = new Properties();
FileInputStream fi = new FileInputStream("your.properties");
p.load((InputStream) fi);
String aaa = p.getProperty("SUMIT_CONFIG", "c:\\sumit\\");

//add you code here
File file = new File(aaa + "\\config.xml");

---your.properties
########################################################
# #
# sample properties file #
# #
########################################################

# lets set SUMIT_CONFIG as c:\sumit\
SUMIT_CONFIG = c:\\sumit\\

你是不能从win2000的环境中得到的，因为系统通过System.getProperties()只能得到如下的东东：
java.version
java.vendor
java.vendor.url
java.home
java.vm.specification.version
java.vm.specification.vendor
java.vm.specification.name
java.vm.version
java.vm.vendor
java.vm.name
java.specification.version
java.specification.vendor
java.specification.name
java.class.version
java.class.path
java.library.path
java.io.tmpdir
java.compiler
java.ext.dirs
os.name
os.arch
os.version
file.separator
path.separator
line.separator
user.name
user.home
user.dir
