I want to create a web application running on Tomcat 7.0 with JRE JavaSE-1.6 on osx 10.8. I am using a tutorial from the developers site and the error occurs when I try to call
clientSecrets = GoogleClientSecrets.load(new JacksonFactory(), reader);
I added the Jar google-http-client-jackson-1.16.0-rc.jar to my build path and still get following error:
java.lang.NoClassDefFoundError: com/google/api/client/json/JsonFactory
java.lang.ClassNotFoundException: com.google.api.client.json.JsonFactory
My classpath specifically points to this Jar too.
I just fixed this by changing the following lines:
Original: import com.google.api.client.json.jackson.JacksonFactory;
Modified: import com.google.api.client.json.jackson2.JacksonFactory;
I had a similar problem and solved it by manually adding the required JAR's to my WEB-INF\lib folder outside Eclipse.
From this page here , it says you need 3 libraries: 1) The Generated Java client library for BigQuery 2) The Google HTTP Client Library for Java 3) The Google OAuth Client Library for Java
Do you have them all? It sounds like you have #2, but it sounds like you're missing the google HTTP client .
In POM add below dependency-
<dependency> <groupId>com.google.api-client</groupId> <artifactId>google-api-client-gson</artifactId> <version>2.1.1</version> </dependency> <dependency> <groupId>com.google.oauth-client</groupId> <artifactId>google-oauth-client-jetty</artifactId> <version>1.34.1</version> </dependency>
Note: In above dependency version can be changed
2.Import statement
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.gson.GsonFactory;
Usage
private static final JsonFactory JSON_FACTORY = GsonFactory.getDefaultInstance(); GoogleClientSecrets clientSecrets =GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
