Replaceregexp tag in build.xml to pass the value dynamically

Question

Hi,
First of all I apologizes as this is not a java question, but sure you guys can help me out. In my build.xml, i have some thing like this:-
<target name="all"
depends="compile,clean_classes,replaceTemplates"/>
<target name="compile"
depends=" create.dir,compileclasses,jar,run"/>
     <target name="clean">
     <delete dir="${build.dir}"/>
     </target>
<target name="clean_classes">
<delete dir="${classes.dir}"/>
</target>
<target name="create.dir" depends="clean_classes">
<mkdir dir="${classes.dir}"/>
</target>
     <target name="replaceTemplates" depends="clean_classes">
          <replaceregexp file="${sourcefiles}/com/test/BusinessService.java"
                              match="%%VALUE%%"
replace="1"/> // this will be fetched dynamically from .properties
</target>
In my BusinessService.java,
I have a String strValue = "%%VALUE%%";
When i ran the build.xml, the strValue is not replaced with the value "1" as been specified in the build.xml. It seems that everything is fine the class file name path, etc. But some how it is not displaying the value "1" inplace of the placeholder? Please clarify.
One more question on this:-
If the value "1" is displayed for strValue variable, and if i have updated the value in the build.xml replace="2" for <replaceregexp>, in such case the updated value "2" wont be populated. Hence what is the approach we need follow, whether we need to create another folder and copy the "src" code there and make the changes in it like instead of:-
<target name="replaceTemplates" depends="clean_classes">
          <replaceregexp file="${sourcefiles}/com/test/BusinessService.java"
                              match="%%VALUE%%"
replace="1"/> // this will be fetched dynamically from .properties
</target>
the new one will be like:-
<target name="replaceTemplates" depends="clean_classes">
          <replaceregexp file="*${build}/*src/com/test/BusinessService.java"
                              match="%%VALUE%%"
replace="1"/> // this will be fetched dynamically from .properties
</target>
Please clarify.
Thanks
