Mandrill Wrapper API JAVA

我在eclipse中开发crm struts web应用程序。为了邮寄目的，我创建了mailchimp账户和mandrill集成。我找到了第三方包装API（cribbstechnologies-Java-Mandrill-Wrapper）。从main方法执行时，它会发出如下异常。我在MandrillHTMLMessage对象中提供了正确的API代码，所有邮件信息。Mandrill Wrapper API JAVA

private BaseMandrillResponse performPostRequest(BaseMandrillRequest request, String serviceMethod, Object responseClass, TypeReference reference) throws RequestFailedException { 
    try { 
     System.out.println("PostRequest Starts"); 
     request.setKey(config.getApiKey()); 
     HttpPost postRequest = new HttpPost(config.getServiceUrl() + serviceMethod); 
     String postData = getPostData(request);

.............

protected String getPostData(BaseMandrillRequest request) throws JsonGenerationException, JsonMappingException, IOException { 
     return objectMapper.writeValueAsString(request); 
}

异常在objectMapper.writeValueAsString（请求）;线如下

Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.codehaus.jackson.JsonFactory._getBufferRecycler()Lorg/codehaus/jackson/util/BufferRecycler; from class org.codehaus.jackson.map.ObjectMapper

如何解决例外。我在谷歌尝试，但没有找到结果。

请谁能帮我...提前

谢谢...
