Glassfish error loading EJB client application container application

Whenever you load an EJB standalone client to be run within a client container into Glassfish 2 you get this error (with a whole stack trace following it):

Error attempting to process extensions from the manifest of JAR file C:\projectlocal\netbeans\SL351_D2\project\Auction\dist\gfdeploy\Auction-ejb.jar; ignoring it and continuing
java.io.FileNotFoundException: C:\projectlocal\netbeans\SL351_D2\project\Auction\dist\gfdeploy\Auction-ejb.jar (The system cannot find the file specified)

The error can be safely ignored, as Tim Quinn explains.

Still it clutters other server output, so I tend to set the deployment logging level (javax.enterprise.system.tools.deployment) to severe in the glassfish console to get rid of it. I just switch it back when in doubt.

Brazilian loggers are hiring hackers to break in to government systems and exceed their quota.
The Brazilian government will respond by raising the quota with 150%.

JMS producer code example

- ejb client container resource injection
- Queue/topic agnostic API (JMS 1.1)

EJB life cycle callback handlers

1 Create a JMS connection when the AuctionManagerBean is created.
   Make the connection an attribute of the bean
2 Close the JMS Connection when the bean is destroyed.

hiking sites

About a year ago a coleague at Uniway told me about geocaching.
Geocaching is a game, where you have to find hidden objects (caches) based on GPS coordinates and hints.
A great way to have an entertaining and beautiful walk in an area you don't know.
With our friends we did a cache related to the flooding of the Yzer estuary in World War I.

This weekend I stumbled upon routeyou, another nice walking site. They have got plenty of descriptions of hikes and bike trips. Here's an example walk.
