Re: Programmatically create a fileset and reference

Not sure that accomplishes what I need to do. The problem I wish to
solve is this:

I have a property that equates to this:

<property name="jdbc.jar" value="C:\Documents and
Settings\jweber\Desktop\db2_test\db2jcc.jar,C:\Documents and
Settings\jweber\Desktop\db2_test\db2jcc_license_cu.jar"/>

The value of this property is variable.

I then have a couple of tasks that perform the following:

  <!-- use filelist to copy the files to a temp dir so we can build a
fileset -->
   <copy toDir=".tmp_cp" overwrite="true" failonerror="false">
     <filelist files="${jdbc.jar}" />
     <flattenmapper/>
   </copy>

  <!-- create a referencable path object to be used in sql task -->
   <path id="sql.cp">
     <fileset dir=".tmp_cp"/>
   </path>*
*
This all works great (although not so straight forward), until there is
a space in one of the paths in jdbc.jar property. If you have another
approach I'd be willing to try but I dont think your suggest will work
for this.
