Problem in displaying image in fop

[Kandukuri, Neelima \(CDC/CCID/OD\) \(CTR\)]

Hi,
    I am trying to generate rtf using xsl-fo. I am having problem in 
displaying a image in rtf. my app structure is 
FO/WebRoot/images/common/test1.gif.
 
code:
 In fop-config.xml
<entry>
       <key>baseDir</key>
       <value>\FOA\WebRoot\images</value>
    </entry>
 
I am calling this xml in java class and seting to userconfig
 fopFactory.setUserConfig(fop-config.xml)
 
In  xsl 
 
<fo:external-graphic src=common/CDClogo.gif /> 
when I use above code I am getting Image not available error.
 
help appreciated, ITs urgent.
 
thanks
