Hi Archana, I see the problem here. When using temporary credentials in AWS, the session token must be included in a request header [1], so you need to provide it when configuring the jclouds context with the credentials.
By default, the "ContextBuilder.credentials" signature does only allow to pass the access key and secret key, but there is no place to specify that session token. However, the ContextBuilder provides an alternate mechanism to configure custom credentials. You can use the "ContextBuilder.credentialsSupplier" method as follows: ContextBuilder.newBuilder("aws-ec2") ... .credentialsSupplier(new Supplier<Credentials>() { @Override public Credentials get() { return SessionCredentials.builder() .accessKeyId("temporary access key") .secretAccessKey("temporary secret key") .sessionToken("session token") .expiration(new Date()) // Change to a proper value .build(); } }) ... Could you try this? HTH! I.
