Re: [Htmlunit-user] I am getting a No Such Method error when I call new WebClient();

[Ashutosh S. <ash...@gm...>]

Please refer to my earlier post.
If you are running your code within a mananged environment(like IBM WAS,
Oracle Weblogic or JBoss etc...) - you will encounter this issue.
As all these managed container has pre-packaged apache httpClient.jar
already and at the runt time - Class loader will load and try to use the
apache httpClient.jar that came with the container and not your bundled one.

We encountered this issue in IBM WAS8.x and used the parent classloading in
WAS Admin console to fix this issue. Parent class loading will make sure
that the apache httpclient.jar that is part of your implementation(under
WEB-INF/lib) is being loaded before the WAS's apache httpclient.jar file.

Hope this helps.
