The following API has been released and available for download:

  • PubSub+ Messaging API for Java 1.0.0

Release Summary

This is the initial release of the PubSub+ Messaging API for Java. Solace created this API to modernize our JCSMP API. This is a separate standalone API which provides modern interfaces, patterns and usability in a native Java environment.

This version contains a feature set that allows for the common messaging patterns like publish/subscribe using Direct Messaging and Guaranteed Messaging. This API provides support for all deployments of PubSub+ across software, appliance, and cloud.

Future versions of the Java API will introduce more features as Solace builds out the roadmap for this API.

The Java API 1.0.0 supports:

  • Connection management to PubSub+ event brokers
  • Addition and removal of topic subscriptions
  • Sending and receiving Direct and Guaranteed Messages
  • Message compression
  • Use of Selectors
  • Kerberos authentication
  • Message Replay
  • Structured data types that allow interoperability between various architectures and programming languages
