com.google.api.client.googleapis.GoogleUtils.getCertificateTrustStore(), no such method.

[kerne...@gmail.com]

am working on a Spring-MVC application in which I would like to integrate Google calendar functionality. The problem I am facing currently is the initial httpTransport line is throwing me method not found error. I will paste the code I am trying to execute. Kindly let me know if that is correct.

• I also wanted to ask where should I give the username as parameter. I guess I will show the code and error.

Error code :

java.lang.NoSuchMethodError: com.google.api.client.googleapis.GoogleUtils.getCertificateTrustStore()Ljava/security/KeyStore;
