Subject AW: Schema generation with Ant
Date Thu, 15 Mar 2012 11:37:03 GMT
Hi Michael,

I found the Ant debug settings :) This seems to be the relevant part of the exception:

Caused by: java.lang.ClassNotFoundException: org.apache.cayenne.dba.postgres.PostgresAdapter
	at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(URLClassLoader.java:190)

	at org.apache.cayenne.di.spi.DefaultAdhocObjectFactory.newInstance(DefaultAdhocObjectFactory.java:51)
	... 22 more

I've added the classpathref attribute to the cdbgen task and verified that it actually contains
the cayenne-server.jar, but the classloader in DefaultAdhocObjectFactory does not load it,
as far as i could debug it.
I tried debugging the DbGeneratorClass in the tools.jar, but had no luck so far.

Regards,
Joerg

Hi Joerg,

Can you include more of the error message?  I didn't see anything
obvious, but I don't really use the Ant plugin, either.

Thanks,

mrg
