i'm using Eclipse (Helios SR1 build 20100917-0705) and Hibernate (latest plugin from JBoss (v3.4.0?)) and Maven (v2.2.1) when i try to reverse engineer a table i get the following:

taskdef class org.hibernate.tool.ant.HibernateToolTask cannot be found

via the web and other posts (here) i found that "hibernate-tools.jar" contains that class. i found that jar file deep in the bowels of Eclipse (plugins/org.hibernate.eclipse_3.4.0.v....) and in several other places in eclipse. i unjar'd the file and verified the class is indeed within it.

so, now i have "hibernate-tools.jar"...but where to put it (or put a reference to it)?? here's what i've tried thus far:
1) i created a system CLASSPATH and added the jar file. No Go (still got class not found)!
2) i copied it into \java\jdk\lib. No Go!
i *think* i need this on the classpath for Eclipse..not my project that needs to be able to reverse engineer classes.

1) why can't Eclipse "see" this file...it's in the plugins directory (several times)?
2) since Eclipse cannot "see" this file...where can i put it s.t. it's in Eclipses' CLASSPATH?

thanks!

when i search for "hibernate-tools.jar" i find it in ....

C:\tools\eclipse\plugins\org.hibernate.eclipse_3.4.0.v20101206-2100-H28-Beta2\lib\tools

since this used to work (2 months ago). i assume i upgraded something i shouldn't have.

i added "hibernate-tools.jar" to the build path of my project. when i now rerun reverse generate i get the following:

java.lang.IncompatibleClassChangeError: Found class org.hibernate.cfg.Mappings, but interface was expected

from other posts i think this is caused by incompatible versions (Core/Tools/Annotations). http://community.jboss.org/wiki/Hiberna ... lityMatrix

just trying to solve the problem ("class not found") that was presented to me. :-(

i've given up on getting this to work on Eclipse Helios as there is only Beta level hibernate support. i've downgraded Eclipse to Galileo and installed Hibernate. now i don't get "class not found". when i run the reverse generate ("Run"..."Hibernate Code Generation") i get a nice progress bar, no errors, yet nothing happens (the table specified in my hibernate.reveng.xml doesn't appear anywhere (least not in the directory/package i specified)).

well...i got it to work. i can now reverse engineer tables. why? well, as best i can figure the DB Driver connection information (NOT the hibernate configuration) was setup incorrectly. I was making screen shots to show you...

when i noticed - during Editing the Hibernate Config file that during Editing the Database Connection i peeked at "Driver Properties" and noticed that i hadn't hit the "Edit Driver Definition" icon/button. when i looked there at the Properties i noticed that the connection string was wrong (default??). i corrected it to match what i had setup for the Hibernate Config and viola! i'm able to revGen!

thanks for your assistance!

p.s. How did you get the ER Diagram in Eclipse????
