Following files need to be changed along with mentioned changes:

  • LinkedinApiUrls.properties: Following code needs to be added under APIs mentioned under companies:

  • LinkedInApiUrls.java: Following code needs to be added:
    public static final String GET_COMPANY_STATUS_UPDATES = linkedInApiUrls.getProperty("com.google.code.linkedinapi.client.getCompanyStatusUpdates");
    
  • CompaniesApiClient.java: Following APIs need to be added:
    				
    /**
     * Gets the company by id.
     * 
     * @param id the id
     * 
     * @return the company by id
     */
    public Updates getCompanyStatusUpdates(String id);
    			
    				
    /**
     * Get comanpy updates by companyid and event type 
     * @param id
     * @param eventType
     * @return
     */
    public Updates getCompanyStatusUpdates(String id, String eventType );
    
    /**
     * Get company updates by companyid, event type, start index, count
     * @param id
     * @param eventType
     * @param start
     * @param count
     * @return
     */
    public Updates getCompanyStatusUpdates(String id, String eventType, int start, int count);
    
  • BaseLinkedInApiClient.java: Following implementations need to be added:
    				
    	@Override
    	public Updates getCompanyStatusUpdates(String id) {
            assertNotNullOrEmpty("id", id);
    
            LinkedInApiUrlBuilder builder = createLinkedInApiUrlBuilder(LinkedInApiUrls.GET_COMPANY_STATUS_UPDATES);
            String                apiUrl  = builder.withEmptyField(ParameterNames.FIELD_SELECTORS).withField(ParameterNames.ID,
            									id).buildUrl();
    
            return readResponse(Updates.class, callApiMethod(apiUrl));
    	}
    	
            @Override
             public Updates getCompanyStatusUpdates(String id, String eventType) {
                    assertNotNullOrEmpty("id", id);
                    assertNotNullOrEmpty("eventtype", eventtype);
                    LinkedInApiUrlBuilder builder = createLinkedInApiUrlBuilder(LinkedInApiUrls.GET_COMPANY_STATUS_UPDATES);
                    String apiUrl = builder.withEmptyField(ParameterNames.FIELD_SELECTORS)
                                           .withField(ParameterNames.ID, id)
                                           .withParameter(ParameterNames.EVENT_TYPE, eventType).buildUrl();
    
                    return readResponse(Updates.class, callApiMethod(apiUrl));
             }
    	
            @Override
            public Updates getCompanyStatusUpdates(String id, String eventType,
                           int start, int count) {
                    assertNotNullOrEmpty("id", id);
    
                    LinkedInApiUrlBuilder builder = createLinkedInApiUrlBuilder(LinkedInApiUrls.GET_COMPANY_STATUS_UPDATES);
                    String apiUrl = builder.withEmptyField(ParameterNames.FIELD_SELECTORS)
                                    .withField(ParameterNames.ID, id)
                                    .withParameter(ParameterNames.EVENT_TYPE, eventType)
                                    .withParameter(ParameterNames.START, String.valueOf(start))
                                    .withParameter(ParameterNames.COUNT, String.valueOf(count))
                                     .buildUrl();
    
                    return readResponse(Updates.class, callApiMethod(apiUrl));
            }
    

Once above files have been modified, you are all set to access the company status updates using following code:

public static void main(String[] args) {

        String consumerKeyValue = "your-consumer-key";
        String consumerSecretValue = "your-consumer-secret";

        String accessTokenValue = "use-your-access-token-value";
        String tokenSecretValue = "use-your-token-secret-value";

        final LinkedInApiClientFactory factory = LinkedInApiClientFactory.newInstance(consumerKeyValue, consumerSecretValue);
        final LinkedInApiClient client = factory.createLinkedInApiClient(accessTokenValue, tokenSecretValue);
	
        Updates updates = client.getCompanyStatusUpdates( "1441", "status-update", 10, 10 );
        List ulist  = updates.getUpdateList();
        if( ulist != null ) {
                Iterator uiter = ulist.iterator();
                while( uiter.hasNext() ) {
                        Update update = uiter.next();
                        CompanyStatusUpdate csu = update.getUpdateContent().getCompanyStatusUpdate();
                        if( csu != null ) {
                            System.out.println( "Status Updates: " + cssu.getShare().getComment() );
                        }
                }
        }
}
