Handler processing failed; nested exception is java.lang.NoClassDefFoundError: org/apache/http/client/protocol/HttpClientContext

Question

I am struggling with a NoClassDefFound exception in access to spring-social linked in and facebook. What is strange is I have a project which works using the same code for connexion and one which does nt. I have gone thru the differences between the 2 of them and doesnt see any which makes sense to me.

Here is the full trace I get. Any hint or search direction is welcome.

    type Exception report
    message Handler processing failed; nested exception is java.lang.NoClassDefFoundError:     org/apache/http/client/protocol/HttpClientContext

Answer 1

org/apache/http/client/protocol/HttpClientContext is a class packaged in httpcomponents-client since the 4.3 (https://hc.apache.org/httpcomponents-client-4.3.x/httpclient/apidocs/org/apache/http/client/protocol/HttpClientContext.html). I think you don't have the right version or the project at all.

Try adding this:

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.3.2</version>
</dependency>
