[Trinidad] How do I convert image url's to absolute paths?

[Korhan Bircan]

Does anyone know how I can convert image url strings (eg. 
url('/adf/images/close.gif')) to absolute paths (eg. C:\Documents and 
Settings\user\Application 
Data\JDeveloper\system11.1.1.1.32.51.70\o.j2ee\drs\trinidad\trinidad-demo-webapp\WEB-INF\classes\META-INF\adf\images\close.gif)?  
I'm in *.trinidad.internal.style.cache.FileSystemStyleCache.java.

Thanks in advance,
