Accessing a directory on Unix

[Jain, Manish (MED, TCS)]

 Hello,
       I have read in the ant documentation that build files have access
  to environment variables, but I am unable to get this to work. On DOS
prompt
  I am setting a variable:  

 set WEBAPP=//<IP ADDRESS>/a/b/c (I intend to give a directory on Unix
box)

 In my build.xml, I  have the following  lines:

        <property name="src" value="${myenv.WEBAPP}"/>
        <property name="dist" value="${myenv.WEBAPP}/dist"/>
         
        <mkdir dir="${dist}"/>

 
 I am running this build.xml from my NT machine.My build.xml is unable
to read WEBAPP as a unix path (it is reading it as 
 DOS path \\<IP ADDRESS>\a\b\c )
 and is failing to create the dist directory on Unix machine(error
message: directory creation was not successful for an  unknown reason).
 Can someone please point out what I am doing wrong here?  Or if this is
 a known problem?

 
 Thanks,
 Manish
