SleepyBatchlet sample for Java EE7

SleepyBatchlet is a simple sample batchlet for use with the Batch Programming Model in Java EE 7, as specified by JSR 352.

The batchlet itself is rather uninteresting. All it does is sleep in 1 second increments for a default time of 15 seconds. The sleep time is configurable via batch property sleep.time.seconds. The batchlet prints a message to System.out each second, so you can easily verify that it's running.

WAS Liberty

Maven

The sample can be built using Apache Maven. In the directory where you cloned the repository issue the following command to build the source.

n install

Then, in the sleepybatchlet-webapp directory issue the following command to run it on a Liberty server.

n liberty:run-server

WebSphere Development Tools (WDT)

The WebSphere Development Tools (WDT) for Eclipse can be used to control the server (start/stop/dump/etc.), it also supports incremental publishing with minimal restarts, working with a debugger to step through your applications, etc.

WDT also provides:

• content-assist for server configuration (a nice to have: server configuration is minimal, but the tools can help you find what you need and identify finger-checks, etc.)
• automatic incremental publish of applications so that you can write and test your changes locally without having to go through a build/publish cycle or restart the server (which is not that big a deal given the server restarts lickety-split, but less is more!).

Installing WDT on Eclipse is as simple as a drag-and-drop, but the process is explained on wasdev.net.

To import the source code into Eclipse/WDT:

1. In the Enterprise Explorer view, right click and select Import -> Existing Maven Projects
2. Browse… to the top level directory titled sample.javaee7.sleepybatchlet
3. Verfiy all three boxes are checked and select Finish

Manual Deployment

1. Add batch-1.0 to your server.xml.

2. Install the sample app to your server by copying sample.javaee7.sleepybatchlet.war that was made from running mvn install

3. Start the server.

4. Run the sample by hitting the following URL using your servers hostname and port

   http://hostname:port/sample.javaee7.sleepybatchlet/

WAS Traditional

Note: In WebSphere Application Server traditional the support for JSR 352 is limited to an in-memory (non-persistent) job repository.
