== Gearman-Java library ==

A "pure java" implementation of the Gearman "client" and "worker" interfaces.

For the time being, portions of this library are licensed under the LGPL
license while other portions are licensed under BSD. We seek to rectify
this 'mix of licenses' in the very near future.

== KNOWN ISSUES ==

- Client and Worker will not attempt to re-establish connection to server if
  the connection drops.

== RUNTIME REQUIREMENTS ==

- JDK 5 or greater.

- A Gearman Job Server. The gearman-java library has been tested using the 0.8 C
  based gearmand Gearman Job Server, but in theory it should work with any
  server that understands the Gearman Protocol.

== BUILD REQUIREMENTS ==

- JDK 5 or greater.

- Ant 1.7 (may work with earlier versions).

- JUnit 4.6 (Junit only required if you want to run the regression suite).

== HOW-TO/EXAMPLES ==

- How to build the project jar file

  1) Ensure that ant 1.7 is on your path

  2) Change your working directory to the root of the gearman-java project.

     % cd ${PROJECT_ROOT}
  
  3) From the project root, execute an ant build specifying the 'dist'
     target.

     % ant dist
   
  4) When the build has completed, the jar file will be placed in the
     ${PROJECT_ROOT}/dist/lib directory and will be called
     gearman-java-${version}.jar (where ${version} represents the 
     current version number).

- How to build and run the regression suite

  1) Follow the steps used to build the project jar file (see above).

  2) Make sure that you jave JUnit 4.6 on your system and preferably on your
     class path.

  3) Start an instance of the gearmand server running on your localhost and
     listening on the default port.
     
     % ${PATH_TO_GEARMAND_BIN_DIR}/gearmand &

  4) From the project root, execute an ant build specifying the 'test' target.

     % ant test

     Note, if you do not have JUnit 4.6 on your class path, when you start
     the ant build you will need to specify the location of the JUnit jar file
     via the junit.jar property as shown below.

     % ant -Djunit.jar ${PATH_TO_JUNIT46_JAR} test

- How to use the example reverseFunction and reverseClient to reverse a 
  String.

  1) Start a Gearman Job Server running on your localhost and listening on 
     the default port.

     % ${PATH_TO_GEARMAND_BIN_DIR}/gearmand &

  2) Start the example reverse worker in a Java VM and background the job.

     % java -cp <PATH_TO_GEARMAN_JAVA_JAR> org.gearman.example.WorkerRunner \
       org.gearman.example.ReverseFunction &

  3) Execute the example reverse client, passing in the string you want to
     reverse.

     % java -cp <PATH_TO_GEARMAN_JAVA_JAR> org.gearman.example.ReverseClient \
       "hello world"

- For more examples on how to use gearman-java, see 
 ${PROJECT_ROOT}/src/org/gearman/examples. The following examples are worth
 noting:

 -ReverseClient.java: Shows how to create an instance of client, submit a job,
  and retrieve the job's results.

 -ReverseFunction.java: Shows how to implement your own function.

 -WorkerRunner.java: Shows how to create an instance of a worker and have it
  process jobs from a job server.
