Re: Problems running the examples
I'm fine with that. I had an Apache-licensed project and included it. I have not found a crystal-clear statement on how the EJB specification classes are licensed, but I would be shocked if one cannot redistribute these API jars. I moved this out of the main code and into an examples directory so at least the main code does not depend on this either way, so that it would be less of an issue. You could argue it's fine to ask users to download ejb.jar to build examples... but I personally also think it is OK to include the EJB spec classes in this project's distribution.

Re: Problems running the examples
By the way, that heap size error message you got is not from running out of memory, but from the JVM not being able to allocate the initial heap size on startup. This usually comes from a typo of some kind in the "-Xms" or "-Xmx" flag. For example "-Xmx256" does not mean 256MB, it means 256 bytes. :) That causes this error. Or if you try "-Xmx4096m" on a 32-bit machine, well, you're not going to quite make it either. Yes there is no ejb.jar for license reasons. Really... I am not sure people use session EJBs anymore. I wrote that for EJB 2.1 a couple years ago and don't know if anyone ever used it. In the transition to "Taste 2.0" I shed some old stuff like that. I didn't remove it, just put it in the examples directory.

Re: Problems running the examples
The test run fine, its the examples that didn't run correctly, but I found a way to run them, by playing with the HADOOP_HEAPSIZE option in conf/hadoop-env.sh, it defaults to 1000 MB, I just set it to 128 and now its ok... by the way the Taste examples are missing a dependency (ejb.jar), is there a good reason not to include it (License issues perhaps) ? --- En date de : Mar 1.7.08, Jeff Eastman <[EMAIL PROTECTED]> a écrit : De: Jeff Eastman <[EMAIL PROTECTED]> Objet: Re: Problems running the examples À: mahout-dev@lucene.apache.org Date: Mardi 1 Juillet 2008, 17h32 I had to use an -Xmx 256m to get the tests to run without heap problems.
