Hi,

I'm trying to use the httpclient within Jython (see
http://jakarta.apache.org/commons/httpclient/ for more information on
the httpclient).

My Jython version is:
Jython 2.1 on java1.4.2_04 (JIT: null)

My Java version is:
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

My CLASSPATH includes:
jdom.jar
xerces.jar
jython.jar
jt400.jar
log4j-1.2.8.jar
commons-httpclient-2.0.jar

When I just try to perform the import statements from example code I
get the error pasted below.

import org.apache.commons.httpclient.Cookie
import org.apache.commons.httpclient.HttpClient
import org.apache.commons.httpclient.HttpState
import org.apache.commons.httpclient.cookie.CookiePolicy
import org.apache.commons.httpclient.methods.GetMethod

Thanks for any help you can provide. If this is the wrong
forum...point me the right way.

This has nothing to do with Python or Jython.

You're missing Jakarta's commons LOGGING package.
(commons httpclient requires that jar).
Get it from the same place as commons-httpclient.
