<antcall> opens a new scope for properties. Properties which are set
in the called target are not available in the calling target. Therefore
this should work:

<target name=3D"A">
    <antcall target=3D"B"><param name=3D"filename" =
value=3D"file1"/></antcall>
    <antcall target=3D"B"><param name=3D"filename" =
value=3D"file2"/></antcall>
</target>

<target name=3D"B.check">
    <available property=3D"filename_exist" file=3D"${filename}"/>
</target>

<target name=3D"B" depends=3D"B.check" if=3D"filename_exist">
    <echo>filename ${filename} exist</echo>
</target>

That should work without any external task library and with Ant 1.5.



For easier scripting AntContrib [1] could be something for you:

<target name=3D"A">
    <foreach param=3D"filename" list=3D"file1,file2" target=3D"B"/>
</target>

<target name=3D"B.check"/>   <!-- same as above -->
<target name=3D"B"/>


And with Ant 1.6 [2] maybe the *def family [3,4,5] would help.
