java.lang.NoClassDefFoundError :-Could not initialize class org.apache.http.impl.conn.ManagedHttpClientConnectionFactory

Question

I'm working on a Spring webservice(SpringWSTemplate) and I am trying to override org.springframework.ws.transport.http.HttpComponentsMessageSender and I have a code like below:

public class CustomHttpComponentsMessageSender extends
org.springframework.ws.transport.http.HttpComponentsMessageSender {
@Override
public WebServiceConnection createConnection(URI uri) throws IOException {

CookieStore cookieStore = new BasicCookieStore();
HttpComponentsConnection conn = (HttpComponentsConnection) super
.createConnection(uri);
HttpClientBuilder httpClientBuilder=HttpClientBuilder.create();
HttpClient httpclient = httpClientBuilder.setDefaultCookieStore(cookieStore).build();
HttpPost httpGet = new HttpPost(uri);
HttpResponse response = httpclient.execute(httpGet);
return conn;
}

}

When the code execution reaches line : HttpClient httpclient = httpClientBuilder.setDefaultCookieStore(cookieStore).build();

I get the following exception

I use the jars in my build path and I have entries of jars in my classpath.

<classpathentry kind="lib" path="lib/httpclient-4.3.3.jar"/>
<classpathentry kind="lib" path="lib/commons-logging-1.1.3.jar"/>
<classpathentry kind="lib" path="/sapadtreco/lib/httpmime-4.3.1.jar"/>
<classpathentry kind="lib" path="lib/spring-ws-core-2.1.4.RELEASE.jar"/>
<classpathentry kind="lib" path="lib/fluent-hc-4.3.jar"/>

Quick help is greately appreciated.

Hi, did you get a solution? I have the same issue, also when I try exploding the jar , I see that the class file it is looking for is already present. — user_mda

It could be due to the invalid/corrupt/missing httpclient-4.3.3.jar file in the class path. Try exploding this file and check if its valid and contains the ManagedHttpClientConnectionFactory class inside it.

hello_earth Over a year ago

actually it is not that ManagedHttpClientConnectionFactory is missing - it cannot be initialized. had to look inside code to understand what was going on. to make the long story short, in my case, my application was referencing an uber-jar where a reference to an older version of httpcore library had crept, and although i referenced a later version in my main app, that older reference was picked up stackoverflow.com/questions/21864521/…
