2014 GSoC project integrated C++ interfaces with GenApp . This seem to be working well. Building on this prototype, GenApp could integrate with Apache Airavata's Java SDK. This project should produce meaningful samples to be released within Airavata's Java SDK. Further explore the long running application support of Airavata.
The project could also explore integrating with Airavata's AMQP based messaging system to get push based messaging support between GenApp, Airavata integration.
