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

[Bill T. <wat...@al...>]

The error is:

Exception in thread "main" java.lang.NoSuchMethodError:
org.apache.http.impl.cookie.BrowserCompatSpecFactory.create(Lorg/apache/http/protocol/HttpContext;)Lorg/apache/http/cookie/CookieSpec;
at com.gargoylesoftware.htmlunit.CookieManager.<init>(CookieManager.java:54)
at com.gargoylesoftware.htmlunit.WebClient.<init>(WebClient.java:136)
at com.gargoylesoftware.htmlunit.WebClient.<init>(WebClient.java:199)
at asst.htmlUnit.RenderJavaScriptMain.main(RenderJavaScriptMain.java:21)

Line 21 of my main program is:

      WebClient webClient = new WebClient();

I have had a lot of trouble instantiating a WebClient because of Class Not
Found errors.  I ended up downloading several extra .jar files to get the
program to get this far.  The .jar files I am using are:

batik-ext-1.6-1.jar
commons-codec-1.9.jar
commons-collections-3.2.1.jar
commons-io-2.4.jar
commons-lang3-3.3.2.jar
commons-logging-1.1.3.jar
cssparser-0.9.14.jar
htmlunit-2.15.jar

nekohtml-1.9.21.jar

Thanks for your input.

Hi,

This is a classpath issue.

You may have different/incompatible HttpClient library version(s).

You can use maven, which automatically handles all dependencies, or use only the jars with HtmlUnit distribution.

Hi,

this is surely a classpath issue. In your list, httpcore-4.3.jar doesn't
look correct. You can download HtmlUnit with all it's dependencies or
use for instance Maven to be sure to have the right versions of the
different libraries.

Cheers,
Marc.

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.
