You can try this way to solve it !
1)Make sure eclipse version is 3.1M4
2)Make sure the jboss ide version is JBossIDE-1.4.1-e30.zip
3)Make sure the hibernate tools plug in version is 3.0alpha1
If all is ok,
you can install it to eclipse,
install jbosside first,and unzip the hibernate tools plug in.
or follow the install instruction from

2. Requirements

After you have downloaded the Hibernate Tools for Eclipse, unpack and copy the plugins to your Eclipse plugins directory. You will also need JDBC drivers for your database available to use the reverse engineering and querying support.
Please note that these tools do not try to hide any functionality of Hibernate. The tools make working with Hibernate easier, but you are still encouraged/required to read the documentation for Hibernate to fully utilize Hibernate.
