Which is the java version supported by dbx sdk 7.0.0

Hi luigiafassina​ 

Because version 7.0.0 has a dependency on jakarta.servlet-api 6.0.0 (which requires Java 11 or higher), you will need to use Java 11 (or higher) to compile and run your project with SDK version 7.0.0.

It is not possible to compile the SDK with JDK 11 and then run it on JDK 8, as Java does not support running code that depends on APIs from a newer JDK on an older JDK.

Thanks for your answer.

One more question to solve my doubts..

This is the only place in my code where I need jakarta.servlet.

private DbxSessionStore getSessionStore(final HttpServletRequest request) {
    HttpSession session = request.getSession(true);
    String sessionKey = "dropbox-auth-csrf-token";
    return new DbxStandardSessionStore(session, sessionKey);
}

I created a custom CustomDbxSessionStore class that implements DbxSessionStore but still uses javax.servlet.http.HttpSession.

import com.dropbox.core.DbxSessionStore;
import javax.servlet.http.HttpSession;

/**
* Custom implementation of DbxSessionStore that uses javax.servlet instead of jakarta.servlet
*/
public class CustomDbxSessionStore implements DbxSessionStore {

private final HttpSession session;
private final String sessionKey;

public CustomDbxSessionStore(HttpSession session, String sessionKey) {
this.session = session;
this.sessionKey = sessionKey;
}

@Override
public String get() {
return (String) session.getAttribute(sessionKey);
}

@Override
public void set(String value) {
session.setAttribute(sessionKey, value);
}

@Override
public void clear() {
session.removeAttribute(sessionKey);
}
}

and I change the getSessionStore(..) method for using this class

private DbxSessionStore getSessionStore(final HttpServletRequest request) {
    HttpSession session = request.getSession(true);
    String sessionKey = "dropbox-auth-csrf-token";
    return new CustomDbxSessionStore(session, sessionKey);
}

It looks like this will allow me to use JDK 8 at runtime, even with the updated SDK.

Dropbox has authenticated me and allows me to import my files. Can you spot any potential issues? Can you suggest some tests to see if something isn't working? My app asks for permission from Dropbox, then imports the files, and if anything changes in Dropbox, it receives notifications and manages them.

We’re not able to assess whether there may be issues in your specific implementation, and we can’t make any guarantees about how your code will behave.

If you run into a specific error or unexpected behavior while using the Dropbox API or the official Java SDK, please share the request and response details (excluding any sensitive data), and we’ll be happy to take a look.

Looking the documentation https://github.com/dropbox/dropbox-sdk-java I see that "The current release of Dropbox SDK Java supports Java 8+" and it is referred to sdk 7.0.0.
Given that my server is running JDK 1.8, what steps should I follow to properly use this SDK in my environment?

I don't need to compile the sdk - I just need to use the SessionStore in the following flow

// V2 api /oauth2/token
DbxWebAuth webAuth = new DbxWebAuth(reqConfig, appInfo);

DbxAuthFinish authFinish = webAuth.finishFromRedirect(redirectUri, sessionStore, params);

FullAccount accountInfo = getDropboxClientInstance().getCurrentAccount(authFinish.getAccessToken());

My goal is to retrieve the AuthorizationToken and verify wheter the user is authorized.

At the moment, with a custom SessionStore implementation that still imports javax.servlet, should I already notice if some flows don't work? Or should I wait until January to be sure that it works?

thanks
