java.lang.NoClassDefFoundError: net/sf/ehcache/CacheExceptio

I'm using the CVS version of seam currently at 1.3.0.ALPHA, and I'm using seam-gen to reverse engineers cruds from the database. I'm sure that the setup is proper since I'm pretty familiar with it and generated a number of applications since version 1.0

Now the thing is that I'm getting the following exception when I'm reversing the code from the database:

$ ./seam.bat generate-entities
Buildfile: d:\workspace\src\java\jboss\jboss-seam-1.3.0.ALPHA\seam-gen\build.xml

Any hint on how to solve this? Is it the ehcache.jar that's missing?

Of course the JAR is missing. Or you need to switch to a different second-level cache provider in your Hibernate configuration.

This is actually a bug in our seam-gen build script - I'm trying to figure out what changed, since something else seems broken...

[fady.matar]

I got it sorted out. I have download the ehcache.jar and placed it in the lib folder of the distribution.

Please not that the jdbc driver must be placed in that directory as well, the previous versions 1.2.1.GA and earlier required those the jars to be copied to the seam-gen/lib directory.

I am also experiencing this problem. I don't understand it, and I don't know what changed.

[gavin.king]

OK, should be all fixed now.
