jboss-5.1.0.GA + ejb3-tutorials\source\entity = NameNotFoundException

gebro Jun 9, 2010 4:25 PM

Hi everyone,

I am new to the world of application servers and EJB and read through the jboss ejb3 tutorials: http://docs.jboss.org/ejb3/docs/tutorial/1.0.7/html_single/index.html

Everything worked fine when deploying and running the examples stateless and stateful with ant.

But now I face the following Problem when trying to run entity from a clean server:

Me@JoeWin /cygdrive/c/Programme/jboss-5.1.0.GA/source/entity
$ ant run
Buildfile: C:\Programme\jboss-5.1.0.GA\source\entity\build.xml

prepare:

compile:
    [javac] C:\Programme\jboss-5.1.0.GA\source\entity\build.xml:52: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to
false for repeatable builds

ejbjar:

I noticed that some NameNotFound exceptions occure sometimes even with examples that worked before. I guess this is due to the slowness of my PC. Probably the Application is still not deployed and ant already tries to run it on the server, but, as I said, I am just guessing there.

So the second Exception occurs all the time now, no matter how often I try to run it.

It would be kind if you could help me to correct the problem.

Thanks a lot,

Johannes

Hi,

does your app deploy without errors (check the console output of your jboss server)?

If this is really a timing issue, you might add a "sleep" statement to your build.xml:

{code:xml}
<sleep seconds="60"/>
{code}

Hope this helps

Wolfgang

I actually thought we did have sleep in the tutorial builds to wait for a few seconds before the application is deployed. But looking at it now, I don't see any. So yes, as Wolfgang suggests, you might want to add that sleep in the build. Or you can run the "ejbjar" and the "run" target separately:

ant ejbjar

and then check the server console to see that the application is deployed. After the application is deployed, run

ant run
