Subject Re: version compatibility plugin?
Date Thu, 03 Jul 2008 14:09:40 GMT
Hi Joe,

You could try adding

            <scope>provided</scope>

to the org.apache.geronimo.configs/jasper/{version}/car dependency in
the pom.xml.   I 've seen a similar error like this before and by
adding the scope fixed it.

Thanks,

Lin
