kandi X-RAY | fabric-sdk-java Summary

fabric-sdk-java is a Java library typically used in Blockchain applications. fabric-sdk-java has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has medium support. You can download it from GitHub, Maven.

The SDK provides a layer of abstraction on top of the wire-level protobuf based communication protocol used by client applications to interact with a Hyperledger Fabric blockchain network. It allows Java applications to manage the lifecycle of Hyperledger channels and user chaincode. The SDK also provides a means to execute user chaincode, query blocks and transactions on the channel, and monitor events on the channel. The SDK acts on behalf of a particular User which is defined by the embedding application through the implementation of the SDK's User interface. Note, the SDK does not provide a means of persistence for the application defined channels and user artifacts on the client. This is left for the embedding application to best manage. Channels may be serialized via Java serialization in the context of a client. Channels deserialized are not in an initialized state. Applications need to handle migration of serialized files between versions. The SDK also provides a client for Hyperledger's certificate authority. The SDK is however not dependent on this particular implementation of a certificate authority. Other Certificate authority's maybe used by implementing the SDK's Enrollment interface. This provides a summary of steps required to get you started with building and using the Java SDK. Please note that this is not the API documentation or a tutorial for the SDK, this will only help you familiarize to get started with the SDK if you are new in this domain.

            How to notify client of block commit and/or transaction status using events in HLF?
            Asked 2020-May-08 at 07:28

            I am working on a client that needs to be notified of the status of any given blockchain transaction. To that end I am learning how to make use of events to achieve this. I tried referring to the official documentation on events in HLF 1.4 (found here) but the link to the SDK documentation is dead. I also found this question but the provided links are all dead as well.

            Then I came across the Fabric Gateway implementation (mentioned here), and I found BlockListenerTest, which forms the basis for this question.

            My current scratch code looks like this:

            To use the high level Gateway SDK, you need to start by creating a Gateway object, then get a network object from that (use the sample code here as a start). From the network object, you can invoke addBlockListener() passing in your consumer function. Then when you invoke submitTransaction on your contract object, your listener should get invoked.

            In terms of tests, you're probably better off looking at the scenario test code here, here and here for examples of usage.
