Subject Re: Error trying to enhance at build time
Date Thu, 04 Mar 2010 22:31:03 GMT
Hi remmons,

The PCEnhancer requires the path to the file instead of the package.  For
example:

To compile: javac -cp openjpa-all-2.0.0-beta2.jar;.
com\aurigen\openjpanys\Message.java

then...

To enhance: java -cp openjpa-all-2.0.0-beta2.jar;.
org.apache.openjpa.enhance.PCEnhancer
com\aurigen\openjpanys\Message[.java|.class]

hth,

-Jeremy
