Accessing object storage bucket with a pre-authenticated request using oci java sdk

Question

I have only preauthenticated URL,namespace and bucket name. Is there any way to upload and download data using key with help of oci java sdk. Is there a proper documentation for this, and If there is then which version of java and maven it supported and all the dependencies with it.

I was trying, firstly make a builder with endpoint(URL). Using builder make a objectStorageClient but in argument it requires AuthenticationDetailsprovider. So I pass an empty object of AuthenticationDetailsprovider. But I am getting this error.

java.util.NoSuchElementException: No http provider available; add dependency on one of the oci-java-sdk-common-httpclient-* choices, e.g. oci-java-sdk-common-httpclient-jersey at

Answer 1

Please refer to the documentation for how to create PARs using the Java SDK.

I believe you haven't created your configuration file properly, which you are passing to AuthenticationDetailsprovider. Basically, the following line of code parses the default profile from the config file added. You should not pass an empty object.

final ConfigFileReader.ConfigFile configFile = ConfigFileReader.parseDefault();
