[Max Rydahl Andersen (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-4531?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12475280#action_12475280 ] 

Max Rydahl Andersen commented on JBIDE-4531:
--------------------------------------------

1) this file should just stay there in both M2 and M3 for now. 
It is there so Hibernate Tools can load the class SeamUtil when asked for it, if you put it into the seam plugins it wont work since hibernate does not have access to their classes.

2) The right solution for this is in trunk is to when we execute seam-gen to add the seamgen.jar to the classpath of the console configuration used to run with it. Then it should pick it up correctly and we would not need to have this copy/pasted class anymore.

> When using Jboss Tools's "Generate Entities", a ClassCastException occurs and the entities cannot be generated when clicking on the "Finish" button (see screenshot).
> The exception message is:  "org.hibernate.tool.hbm2x.ExporterException: Exception when instantiating tool hibernatetool.util.toolclass with org.hibernate.eclipse.launch.SeamUtil".
> The root cause seems that the org.hibernate.eclipse.launch.SeamUtil class could not be found (ClassNotFoundException).
> In JBossTools-ALL-win32-3.0.1.GA-R200905070146-H18.zip, there was a SeamUtil class in "eclipse\plugins\org.hibernate.eclipse_3.2.4.GA-R200905070146-H18\org.hibernate.eclipse.jar\org\hibernate\eclipse\launch\"
> In JBossTools-ALL-win32-3.1.0.M2-N200906241801-H293.zip, this is not the case anymore: the "launch" package is no more in "eclipse\plugins\org.hibernate.eclipse_3.3.0.M2-N200906241801-H293\org.hibernate.eclipse.jar\org\hibernate\eclipse\"
> Since there is a workaround, I set the severity to "Critical" rather than "Blocker".
