Hi,

I've been using Middlegen-Hibernate-r5 and it's been working great. just recently, I can no long be able to generate java files using hbm2java in Middlegen. I'm getting this error:

I've checked my classpath and made sure all the jar files are there. Everything seems to be in place, but I'm not sure why it stops working on my computer. Any idea? Any body?

C:\Middlegen-Hibernate-r5>ant
Buildfile: build.xml

hbm2java:
[hbm2java] Processing 3 files.
[hbm2java] Building hibernate objects

You obvious know what the error message is saying, eg, classpath issue. It was working and now it is not - ask yourself what you had changed? Sorry but this is the best that can be offered.
