Re: Programmatically create a fileset and reference

Replies:
Seems like the most simple approach. Transforming the csv file to be
line delimited is not an issue, however something else seems to be amiss.

CSV file after transform:

C:\Documents and Settings\jweber\Desktop\db2_test\db2jcc_license_cu.jar
C:\Documents and Settings\jweber\Desktop\db2_test\db2jcc.jar

Copy Test:

   <copy toDir="./destination">
     <files includesfile="file.csv"/>
   </copy>

Yields the following weirdness:

  [copy] C:\Documents and Settings\jweber\Desktop\db2_test\db2jcc.jar
omitted
as C:\Documents and Settings\jweber\Desktop\db2_test\db2jcc.jar is up
to date.
  [copy] C:\Documents and
Settings\jweber\Desktop\db2_test\db2jcc_license_cu.
jar omitted as C:\Documents and
Settings\jweber\Desktop\db2_test\db2jcc_license_
cu.jar is up to date.
  [copy] No sources found.

Its Monday, am I missing something here?
