Getting started

Add the following Maven/Gradle dependencies:

Feature Artifact
Servlet integration for defining fiber-per-request servlets. co.paralleluniverse:comsat-servlet:0.7.0
A fiber-blocking Clojure Ring adapter based on Jetty 9.3. co.paralleluniverse:comsat-ring-jetty9:0.7.0
HTTP Kit-based fiber-blocking HTTP client. co.paralleluniverse:comsat-httpkit:0.7.0
Jersey server integration for defining REST services. co.paralleluniverse:comsat-jersey-server:0.7.0
Dropwizard integration including Jersey, ApacheHttpClient and JDBI. co.paralleluniverse:comsat-dropwizard:0.7.0
Spring Framework Web MVC fiber-blocking controller methods integration. co.paralleluniverse:comsat-spring-webmvc:0.7.0
Spring Boot auto-configuration support for Web MVC controllers. co.paralleluniverse:comsat-spring-boot:0.7.0
Spring Security configuration support for fibers. co.paralleluniverse:comsat-spring-security:0.7.0
JAX-RS client integration for HTTP calls with fibers. co.paralleluniverse:comsat-jax-rs-client:0.7.0
ApacheHttpClient integration for HTTP calls with fibers. co.paralleluniverse:comsat-httpclient:0.7.0
Retrofit integration with fibers. co.paralleluniverse:comsat-retrofit:0.7.0
JDBI integration with fibers. co.paralleluniverse:comsat-jdbi:0.7.0
JDBC integration with fibers. co.paralleluniverse:comsat-jdbc:0.7.0
jOOQ integration with fibers. co.paralleluniverse:comsat-jooq:0.7.0
MongoDB fiber-blocking integration for the Allanbank API. co.paralleluniverse:comsat-mongodb-allanbank:0.7.0
OkHttp HTTP+SPDY client integration. co.paralleluniverse:comsat-okhttp:0.7.0
The Web Actors API. co.paralleluniverse:comsat-actors-api:0.7.0
Deploy HTTP, SSE and WebSocket Web Actors as Undertow handlers. co.paralleluniverse:comsat-actors-undertow:0.7.0
Deploy HTTP, SSE and WebSocket Web Actors as Netty handlers. co.paralleluniverse:comsat-actors-netty:0.7.0
Deploy HTTP, SSE and WebSocket Web Actors in J2EE 7 Servlet and WebSocket (JSR-356) embedded and standalone containers. co.paralleluniverse:comsat-actors-servlet:0.7.0
Use Comsat in the Tomcat servlet container without the java agent. co.paralleluniverse:comsat-tomcat-loader:0.7.0[:jdk8] (for JDK 8 optionally add the jdk8 classifier)
Use Comsat in the Jetty servlet container without the java agent. co.paralleluniverse:comsat-jetty-loader:0.7.0[:jdk8] (for JDK 8 optionally add the jdk8 classifier)
Spring Framework Web integration allows using fiber-blocking controllers. co.paralleluniverse:comsat-spring-web:0.7.0
Apache Kafka producer integration module. co.paralleluniverse:comsat-kafka:0.7.0
Apache Shiro realms integration module. co.paralleluniverse:comsat-shiro:0.7.0

Or, build and install from sources (after installing Gradle locally) in your local maven repository with:

gradle install

The full testsuite can be run with gradle build.


A Gradle template project and a Maven archetype using various integration modules and featuring setup with both Dropwizard and standalone Tomcat are also available for jumpstart and study. Both have a without-comsat branch which is useful to clearly see the (minimal, if any) porting effort required (branches comparison works very well for this purporse).

There's a Comsat-Ring Clojure Leiningen template as well which includes an auto-instrument branch that doesn't need any explicit suspendable-marking code (suspendable!, defsfn, sfn etc.) thanks to Pulsar's new auto-instrumentation feature.

You can also have a look at additional examples.

Finally there are several regularly updated third-party bootstrap projects: Comsat + Dropwizard + jOOQ, Comsat Web Actors Stock Quotes (ported from Akka), Spring MVC + Tomcat standalone servlet container.
