> Hi *,

> I'm trying to make my web app run under tomcat but I'm experiencing
> problems with "scala-library-2.9.0-1.jar".
> If I take it off from lib folder the app run smoothly (without Cypher), as
> soon as I take it in tomcat does not starts.
> The app with cypher works great as standalone.

> Stack trace throws out an heap space issue, but I tried to increase tomcat
> heap and nothing changes.
> It gives the same error even with blank project with no code using that
> library.

> Any ideas? Could anyone make neo4j work as web app using the java embedded
> version and cypher?

> Thanks,
> Daniele
