What versions of Apache commons jars?

[thedesktop]

FDS includes a few Apache jars in WEB-INF/lib that it needs
to work properly (such as commons-loging.jar and
commons-httpclient.jar). I can't find a definition anywhere of
which versions of these jars are required. I'm getting the
equivalent in Java of "dll hell" - a version clash between FDS and
the Java code I'm integrating into FDS, specifically with
commons-httpclient.jar. Anyone know which versions of these jars
FDS supports?

FDS 2 shipped the following versions of apache jars in
/WEB-INF/lib (you can usually find this info inside a jar in the
/META-INF/MANIFEST.MF file).



Apache Commons HTTPClient 3.0

Apache Commons Codec 1.2

Apache Commons Logging 1.0.4



(The other apache jars under /WEB-INF/flex/jars are not in
normal the web app classpath and are for the MXML webtier compiler
only).



Have you tried deleting the commons-logging.jar that ships
with FDS?



Can you give me more details on specifically what error
you're seeing? What application server are you deploying on? What
is the nature of the deployment, how many apps, servers etc. We've
probably dealt with specific conflicts before so we may be able to
help.

Thanks for the reply.



Note that the problem I'm having is with httpclient.jar not
logging.jar. Yes, I have tried using the jars that ship with FDS.
I'm assuming I'm not at liberty to change any of the jars that ship
with FDS as I don't want to break FDS. The problem is that the code
I'm integrating in with FDS was built against
commons-httpclient-2.0.2.jar. This call fails when it runs against
the Apache Commons HTTPClient 3.0 jar that ships with FDS.



org.apache.commons.httpclient.util.EncodingUtil.formUrlEncode(
httpclient.NameValuePair[] pairs , "UTF-8" ) ;



It's not a big deal as I can modify the code to make it work
with the newer v3.0 jar but without your answer I had no way of
knowing whether FDS depended on a later or earlier version of the
jar.



I suspect this jar version information should be in the
Release Notes.

Yes, you're right. I'll log a bug and inform release
engineering to ensure this is fixed for future releases.
