Including other xml files in build.xml

[Mills, Maurice]

I am trying to include a generic xml file in various build.xml files.  This
is how I am doing it:

<?xml version="1.0"?>

<!DOCTYPE web-app [
    <!ENTITY common SYSTEM "..\common\cinfin_build.xml">
]>

<project ....>

  ....

  %common;
  
  
</project>

When I try to run the build I get the following message.

BUILD FAILED

C:\workarea\TestApp\.\build.xml:5: Relative URI
"..\common\cinfin_build.xml"; can not be resolved without a document URI.

I think this means that it can not handle the relative path, however I need
it to be relative because it may change from one machine/user to the next.

Any suggestions?

Thanks,
Maury
