Replacing tokens in file does not work!!

[Arun <ar...@gmail.com>]

Hi,

I am trying to implement a build number system where all static files in my
web application will have a build number appended the filenames.
Basically I am caching everything and when a new build happens all cache
should get cleared.
I have done renaming the files using <mapper> inside <fileset> element.
As a second step I need to add the same to all the filenames inside jsps
like accountmanager.js should be accountmanager_1.0.b25.js.
I have created a properties file which contain the original filenames. I
have used <pathconvert> and my own ant task to do this.
So this propery file gives all files that needs to be renamed and its new
name with build number appended.

I dont want to add @ @ to my tokens as that is not practical. I just want to
replace all occurences of these tokens inside all the jsp's with values as
in property file. I tried it for so long and finally came to filter chain ,
but it also did not do the job.
Does not ant have a way of replacing strings?.
Can I not have a token without any beginning and ending token?
I just want to rename the filenames inside the jsps. I dont want to edit my
jsps and add beginning token and ending token.
I tried ReplaceToken chain , but no help.
Any help is appreciated.


This is what I tried.

<copy todir="${web.build.dir}" >
<fileset dir="web"/>
<filterchain>
<filterreader classname="org.apache.tools.ant.filters.ReplaceTokens">
<param type="propertiesfile"
value="build_number_appended_files.properties"/>
</filterreader>
</filterchain>
<filterset begintoken="@" endtoken="@"
filtersfile="config/somecompanyempbuild.properties"/>
</copy>


Basically I have a fileset which matches certain file extensions and have a
property file which contain string to be replaced and its substitutions. I
dont want to follow any beginning token and end token fashions for this
inside any jsps.
My aim is to replace all static urls with a url which has a build number.
For this all I want to search is for a filename which is static and see its
substition and replace it.

Is it not possible to just do a simple string replace using fileset and
property files.
Any help would be grealty appreciated.
My caching system hangs on it.
